Abstract Aim The purpose of this clinical and radiographic investigation was to evaluate the treatment outcomes of endodontically treated teeth obturated with Soft-Core™ versus cold lateral compaction. Methods and Materials A total of 98 teeth were endodontically prepared using the Quantec LX rotary system with a crown-down pressureless technique and obturated with either Soft-Core™ or cold lateral compaction. The outcome of treatments were evaluated clinically and radiographically by two blinded evaluators after three years. Statistical analysis was performed using an unpaired t-test and the Mann Whitney test at the level of significance set at 95%. Results Regardless of the periapical status of the teeth, no statistically significant difference was found between the two obturation techniques (p>0.05). The Kappa value for the interobserver agreement was 0.73. Conclusion Within the limits of the study, it is concluded the Soft-Core obturation technique did not result in a significantly different treatment outcome when compared with cold lateral compaction after three years. Further investigations should be carried out on the Soft-Core technique. Clinical Significance Using the Soft-Core system reduced working time, and the difference was found to be statistically different (p=0.00056) from the working time required for cold lateral compaction. This reduction in canal filling time holds the potential for cost savings for clinicians while maintaining the quality of the clinical outcome. Citation Özer SY, Aktener BO.

Abstract Aim The aim of this study was to evaluate the effects of multiple consecutive coatings of a one-step self-etch adhesive system (Clearfil Tri-S Bond) on the microtensile bond strength (MBS) to dentin. Methods and Materials Nine caries-free human lower third molars were sectioned perpendicular to the long axis to expose the mid-coronal dentin. The teeth were separated into three experimental groups (n=3) according to the number of adhesive resin coats applied. In Group 1 one layer of Clearfil Tri-S Bond was applied according to the manufacturer's instructions. In Group 2 and Group 3 the adhesive was applied in two and three layers, respectively. In these two groups the first layer was applied according to the manufacturer's instructions but the second and third layers of adhesive were not light cured after application. After the placement of the composite, the teeth were sectioned to obtain approximately 1 mm2 beams for testing. Eighteen beams were prepared for each group using the ‘non-trimming’ method. The MBS values of all specimens were tested, and fracture modes were then determined using a stereomicroscope. Results The mean MBS values (in MPa) of Group 1 (one coat of the adhesive) was significantly lower (p=0.04) than those of Group 3 (three applied coats of the adhesive). There were no statistically significant differences between Groups 1 and 2 and Groups 2 and 3. Conclusion Within the limitations of this in vitro study the application of multiple coats of a one-step self-etch adhesive may provide an increase in bond strength compared to the application of only one coat of adhesive. Clinical Significance Three consecutive coats of one-step self-etching adhesive application can improve MBS. Citation Arisu HD, Eligüzeloğlu E, Üçtaşli M, Ömürlü H.

Abstract Aim To determine the association of impacted maxillary canines with other developmental dental anomalies and compare them with a control population and to compare palatally and labially impacted canine associated anomalies. Methods and Materials Ninety non-syndromic orthodontic patients from a south Indian population, with either labial or palatal impactions of one or both maxillary canine teeth, were selected for the study group. A group of 250 patients who had normally erupted maxillary canines were selected as controls. Clinical findings and panoramic radiographs were used to identify dental anomalies. Results Prevalence of premolar rotation was found to be 80% in the study group followed by canine rotation (20%), taurodontism (26.6%), infraocclusion of premolars (25.5%), impacted mandibular canine (11.1%), and peg lateral (7.7%). Forty-nine (54.4%) palatally impacted, 37 (41.1%) labially impacted, and 4 (4.4%) centrally impacted canines were also observed. Of the 250 subjects in the control group 78.8% presented with premolar rotation. Maxillary canine transmigration, infraocclusion of premolars, anomalies of maxillary lateral incisors, and taurodontism showed significant associations with palatally impacted canines (P<0.05). Conclusion The present study illustrates a significant association of anomalous maxillary lateral, anomalous mandibular canine, taurodontism, infra occlusion of premolar, over retained deciduous molar, and maxillary canine transmigration with ectopically placed canines. These associations suggest these conditions may share a common genetic origin and existence of these anomalies can anticipate maxillary canine impaction which can help in cautious observation and early treatment for maxillary canine impaction. Clinical Significance Anomalous lateral incisors can serve as a predictor for palatal maxillary canine impaction. These anomalies could serve as an easily recognized, early warning sign for the monitoring of the canine position and timely early referral in appropriate cases. Citation Nagpal A, Pai KM, Sharma G.

Abstract Benign fibrous histiocytoma is a rare and usually painless oral neoplasm found in adults that may affect either soft tissue or bone typically noted in their fifth decade. This case was found in a 32 year-old Caucasian male who presented with a fairly well circumscribed unilocular radiolucent lesion extending from the mandibular right first incisor to the left first premolar and reaching the inferior mandible on a panoramic radiograph. A bony window was created and the intrabony lesion was curetted. Multiple sections revealed a cellular tumor composed of uniform spindle-shaped cells arranged in a prominent whorled or storiform pattern. Scattered xanthoma cells, multinucleated giant cells, lymphocytes, and deposits of hemosiderin were noted throughout the lesional stroma. Although malignant fibrous histiocytoma of the bone is relatively well known, benign fibrous histiocytoma of the bone is very rare. Citation Ertas U, Büyükkurt MC.

Abstract Aim The aim of this report is to describe the relationship of some salivary parameters to dental erosion resulting from excessive citric acid consumption and present a description of a prosthetic approach used to restore the damaged dentition of a patient with severe erosion. Background The high consumption of dietary sources of acids can lead to erosion or the excessive wear of dental hard tissues. Erosion may be modified by salivary parameters such as flow rate, pH, and buffering capacity. Porcelain-fused-to-metal (PFM) restorations and composite resin veneers can be used successfully to restore impaired esthetics and eliminate tooth hypersensitivity in such cases. Results A 37-year-old woman with a history of excessive lemon consumption presented with a complaint of tooth hypersensitivity and the poor appearance of her dentition due to erosion. Stimulated and unstimulated salivary samples of the patient were evaluated for flow rate, pH, and buffering capacity before and after treatment. The pre-treatment values were found to be higher than post-treatment values. Stimulated samples showed an increase of salivary flow rate, pH, and buffering capacity. The measured parameters put forth the defensive potential of saliva against the acidic diet, and the salivary flow rate and buffering capacity decreased after reducing acidic consumption. The excessively eroded teeth were restored using PFM restorations whereas the superficially eroded teeth were restored with composite resins. Summary The introduction of acidic foods, beverages, or other agents can exceed the natural buffering capacity of saliva. The result is a lowering of the pH of the oral environment which can lead to erosion of enamel and dentin. Loss of tooth structure due to erosion can compromise the esthetics of the dentition and lead to hypersensitivity of the teeth. Teeth damaged by erosion can be successfully restored by composite resin or porcelain restorations and esthetics and function of dentition can be improved. Clinical Significance This report is a profound example of how the over consumption of acidic agents affect not only dental tissues but also the chemical balance of the oral environment as well as the oral habitat.

Abstract The purpose of this study was to compare the surface pH level of four different type sealers after mixing at various time intervals in vitro. After cleaning and shaping root canals in 50 recently extracted, singlerooted human teeth, they were divided into six groups. Each of four groups was obturated with Apexit, N2, Sealapex, and Grossman sealers. The remaining groups served as controls. In group 1 nothing was added to the vial of saline solution. In group 2 canals had been instrumented but not obturated with sealer. The pH level of saline solutions was determined at intervals of 1 hour, 4 hours, 1 day, 2 days, 3 days, 1 week, and 4 weeks after teeth were placed in them. The pH levels of the five solutions were compared to each other and to that of saline solution only. Citation Evcil MS, Çolak M.

Based on the data of daily maximum temperature in 26 meteorological stations in the North Center Region, Vietnam over the period of 1980 to 2013, the authors conducted the research on the spatial distribution of the number of hot days. The initial result shows that in general, in the north of the study area, the large number of hot days occurred in the plain, and tended to decrease westward and eastward. In the south, this number tends to increase from the west to the east. Especially, the largest number occurred in two areas: The Ma and Ca River's valleys (Thanh Hoa and Nghe An provinces) and the coastal areas (Thua Thien Hue province), creating two heat centers in Tuong Duong district, Nghe An province and Nam Dong district, Thua Thien Hue province.ReferencesAdina-Eliza Croitoru, Adrian Piticar, Antoniu-Flavius Ciupertea, Cristina FlorinaRosca, 2016 Changes in heat wave indices in Romania over the period 1961-2015.

Abstract In this study one-year clinical results of high-viscosity glass ionomer cement (GIC) (Fuji IX, A3, GC, Japan) were determined in class I and class II restorations in 68 primary molars with occlusal or approximal caries. Following caries removal and cavity preparation, the teeth were restored with Fuji IX. The restorations were evaluated according to the U.S. Public Health Service's (USPHS) criteria at the end of one year. Statistical analyses of the data obtained were analyzed using the X2 test. The evaluations showed no statistically significant difference between class I and class II restorations in terms of the color mismatch, anatomic form, marginal adaptation, and secondary caries (P>0.05), but they were statistically significant with regard to cavosurface marginal discoloration (P<0.05). At the end of one year, the success rate of the class I and class II restorations of the primary molars restored with Fuji IX was 94%. Citation Yilmaz Y, Eyuboglu Ö, Kocogullari ME, Belduz M.

Abstract This study investigated weight changes of seven different light-cured composite restorative materials, one polyacid glass ionomer compomer, and one light-cured glass-ionomer cement following short-term and long-term storage in water. Two packable composites, three universal (hybrid) composites, one microglass composite, one polyacid glass ionomer resin composite (compomer), one microhybrid low-viscosity (flowable) composite, and one light cured glass ionomer composite cement were evaluated in this study. The weight changes of these specimens were measured daily (short-term storage), and they were measured after six weeks (long-term storage) using an electronic analytical balance. A significant difference was found in Ionoliner, Dyract AP, Opticor flow, Charisma, and Solitare 2, but no significant difference was found in the others (Filtek Z 250, Filtek P60, TPH Spectrum, and Valux Plus). Weight change showed a tendency to increase with the time of water storage. The greatest weight change occurred in light-cured glass ionomer composite cement (Ionoliner), which is followed in order by the weight changes in Dyract AP, Opticor Flow, Charisma, Solitare 2, Filtek Z250, Filtek P60, TPH Spectrum; Valux Plus had the least amount of change.

Abstract Aim The aim of this report is to present the management of an aggressive, highly proliferative pregnancy tumor with clinical and radiographic characteristics highly suggestive of a malignant neoplasm. Background Pregnancy tumor is a benign hyperplastic gingival lesion occurring during pregnancy that is indistinguishable from a pyogenic granuloma arising in nonpregnant females, or in males. The lesion usually grows over a few months and tends to bleed. Case Description A 28-year-old woman at four months of gestation was referred for a massive gingival swelling (5.5 cm in greatest diameter) on the mandibular left side. The lesion was painful and continued to grow very rapidly over a threeweek period, with spontaneous bleeding, and it interfered with speech and mastication. Advanced alveolar bone loss also was found beneath the lesion. A malignant process was suspected, and an incisional biopsy revealed a pregnancy tumor. The lesion was excised under general anesthesia during the pregnancy with no untoward reactions. Summary Pregnancy tumor represents an important differential diagnosis of oral masses and can behave in a very aggressive fashion, mimicking a malignant tumor. Clinical Significance This lesion should always be included in the differential diagnosis of soft tissue masses in a pregnant woman even if the lesion is clinically very aggressive. It is acceptable practice to excise aggressive variants of this lesion during pregnancy to avoid distressing side effects. Citation Ababneh K, Al-Khateeb T.

Abstract The aims of this study were to determine the characteristics of patients and type of dental treatment carried out using dental general anesthesia (DGA) during two years in a following three year period. A total of 182 patients received treatment between 1999 and 2001. The mean age was 4.9 years. The main indication for DGA was behavior management problems. Complete oral rehabilitation including complex restorative treatment and extractions was provided under DGA at a single visit. Failure to return for recalls was common; 83% of patients returned for the post-operative recall but only 26% after a three year period. Most of the patients requiring further treatment accepted it in the dental chair. Only one patient received a second DGA during the three years following treatment.

Abstract The aim of this study was to evaluate the median survival time of fixed and removable space maintainers related to age groups, gender, and their distribution in upper and lower dental arches. The adherence of patients to a periodic recall program and the success rate of different types of space maintainers related to different arches were also evaluated. This study included 663 patients aged between 4-15 years old that were treated between the years of 1997 and 2002. The patients were categorized into four main groups: lost to follow-up, failed, successful, and censored at the end of study. Three hundred forty-five space maintainers were considered lost to follow-up, 83 were considered failed, 206 successful, and 20 censored-at-end. The overall median survival time of the appliances was 6.51 months. Median survival time was 7.25 months in the 4-6 age group, 6.35 months in the 7-12 age group, and 7.0 months in the 13+ age groups. Median survival time was 5.76 months in girls and 7.11 months in boys. Median survival time of space maintainers was 7.17 months for maxilla and 6.69 months in the mandible. Median survival time was 5.25 months for space maintainers fabricated in both arches. Citation Tulunoglu Ö, Ulusu T, Genç Y.

Abstract Aim The aim of this study was to compare self reported joint related temporomandibular disorder (TMD) symptoms in Lebanese and Italian dental and non-dental students and to detect any correlation between different symptoms. Methods and Materials A questionnaire was distributed in Sardinia (Italy) to dental and psychology students and in Lebanon to dental, physical therapy, and biology students to investigate the prevalence, intensity, and correlation of four temporomandibular joint (TMJ) symptoms. Results Prevalence of earache varied among the groups from 10.1% to 29.2%, ear stuffiness from 22.5% to 30.8%, TMJ pain from 13.2% to 21.2%, and TMJ sounds from 18.4% to 46.2%. Discussion Different prevalence and intensity of earache and TMJ sounds were found in the examined subpopulations diverse in cultural background and education. However, prevalence and intensity of ear stuffiness and TMJ pain were similar. Association between TMJ sounds and TMJ pain was detected in selected subpopulations, and correlation between one symptom on one side of the head with the same symptom on the contralateral side were noted suggesting most of these symptoms are bilateral. Conclusion The results of the study might be useful to anticipate the possible occurrence of associated symptoms or the same symptom on both sides of the head. Correlations with cultural background and education are difficult to establish. Citation Abou-Atme YS, Zawawi KH, Melis M.

Abstract Aim The aim of this research was to evaluate patients. preferences for resin analogs of four major connector designs formulated to have equal rigidity once fabricated in the same alloy Methods and Materials Nineteen Kennedy Class I or II partially edentulous patients participated at two centers. The four major connector analogs (MCAs) were fabricated for each subject using light-polymerizing acrylic resin. The subjects were asked to wear each of them in the mouth for 30 seconds in six pairs in random order, and to report their preference for each pair. Based on these data, the four analogs were ranked in a descending preference order for each patient. Within-subject comparisons preferences were performed with the Friedman test, and the multiple comparisons were performed with the Wilcoxon Signed Ranks test for data of each sample independently. Results Statistically significant and consistent preference orders were revealed for both samples, and the thin and wide design was significantly preferred to the thick and narrow design. However, a higher variation was observed for the first preference of each subject. Conclusions Subjects demonstrated a tendency to prefer thinner MCAs. However, the individual predilections of patients may not be an appropriate basis for an attempt to find a .best design. applicable to all patients.

Abstract Objective The aim of this study was to evaluate the topographic relationship between the inferior dental canals (IDCs) and the roots of impacted mandibular third molars. Methods Preoperative orthopantomograms (OPGs) were examined and the proximity of the IDC to the roots of impacted mandibular third molars was categorized into the following: groups: superimposition, adjacent, perforation, grooving, notching, or none. The categories notching, grooving, and perforation were regrouped together and called the true relationship between the IDC and the root apices. The type of impaction, age, and sex of the patient were also noted. Results The positional category of 96.1% of the radiographs with bilateral impactions was identical on both sides of the mandible. Out of 2526 impacted mandibular third molars examined, 1146 (45.3%) belonged to the superimposition category, 663 (26.2%) were adjacent, 312 (12.3%) showed grooving, 78 (3.08%) showed notching, and 9 (0.35%) were actually perforating the IDC. The results showed 15.7% of the total cases were in true relationship with the IDC. There was a significant association (p = 0.000) between patient's age and true relationship. Conclusions Identical positional relationship of the bilateral impacted third molars to the IDC was noted in 96.1% of the radiographs. The position of the IDC in relation to the roots of impacted third molars varied according to the patient's age. Citation Hazza'a AM, Albashaireh ZSM, Bataineh AB.

Abstract Aim The aim of this study was to evaluate the influence of four photoactivation systems [quartz tungsten halogen (QTH), light-emitting diode (LED), argon ion laser (AL), and plasma arc curing PAC)] on cementum/ dentin and enamel microleakage of Class II restorations using a microhybrid [Z250 – 3M ESPE] and two packable composites [(SureFil - Dentsply and Tetric Ceram HB – Ivoclair/Vivadent]. Methods and Materials Three hundred sixty “vertical-slot Class II cavities” were prepared at the mesial surface of bovine incisors using a 245 carbide bur in a highspeed handpiece. Specimens were divided into twelve groups (composite-photoactivation systems). Half of the specimens had the gingival margin placed in enamel (n=15) and the other half in cementum/dentin (n=15). Composites were inserted and cured in 2 mm increments according to manufacturers’ recommended exposure times. After polishing, the samples were immersed in 2% methylene blue solution, sectioned, and evaluated at the gingival margins. Data were submitted to statistical analysis using the Kruskal–Wallis and Mann-Whitney tests. Results No significant differences were found among the photoactivation systems and among resin composites (p>0.05). Microleakage was not significantly affected by location (enamel vs. cementum/dentin, p>0.05). These findings suggested neither the photoactivation systems nor the resin composite types might have an effect on the microleakage at gingival margins Class II cavities.

Abstract Aim Treatment of periodontal diseases is based on efficient scaling and root planing (SRP) and adequate maintenance of the patient. The effectiveness of SRP is influenced by operator skill, access to the subgingival area, root anatomy, and the quality and type of instrument used for SRP. The aim of this study was to evaluate the cutting edges of Gracey curettes after manufacturing and after resharpening using several techniques. Methods and Material The cutting edges of a total of 41 new #5-6 stainless steel Gracey curettes were evaluated blindly using scanning electron microscopy (SEM). The quality of the cutting edges was evaluated blindly by a calibrated examiner using micrographs. Data were analyzed using a Kruskal Wallis test and nonparametric two-way multiple comparisons. Results and Conclusions Different sharpening techniques had significantly different effects on the sharpeness of cutting edges (p<0.05). Sharpening by passing the lateral face of curettes over a sharpening stone and then a #299 Arkansas stone produced a high frequency of smooth, sharp edges or slightly irregular edges between the lateral and coronal faces of the curettes. Sharpening by passing a blunt stone over the curette's lateral face produced the poorest quality cutting edge (a bevel). Sharpening of the coronal curette face produced extremely irregular cutting edges and non-functional wire edges. Sharpening with rotary devices produced extremely irregular cutting edges.

A discussão em torno de políticas públicas ambientais direcionadas à sustentabilidade da agricultura familiar tem significativa importância no cenário nacional, em vista da contribuição que os pequenos e médios empreendimentos rurais têm dado à preservação do meio ambiente e à criação de empregos e renda. Nesse sentido, a presente pesquisa tece uma analisa das políticas públicas voltadas ao desenvolvimento sustentável da agricultura familiar no município de Parauapebas, localizado no sudeste do Pará. Para a realização deste estudo, primeiramente foi realizado levantamento bibliográfico e documental sobre a temática, seguido da coleta de dados através de documentos institucionais e governamentais disponibilizados pela Secretaria Municipal de Meio Ambiente (SEMMA) e pela Secretaria de Produção Rural (SEMPROR) e, por fim, foi elaborada uma estrutura das políticas públicas distribuídas por esfera governamental. Na expectativa de ocupação e desenvolvimento da Amazônia, foram implantadas políticas públicas que contribuíram para o nascimento de pequenos e médios empreendimentos familiares rurais, que apresentam participação significativa na economia brasileira e necessitam de apoio técnico e financeiro para que desenvolvam suas atividades produtivas alinhadas às práticas de sustentabilidade sob o ponto de vista econômico, social e ambiental. Nesse contexto, dentre as dificuldades apresentadas para o desenvolvimento da agricultura familiar estão: escassez de infraestrutura, dificuldades de acesso à informação e ao aperfeiçoamento técnico, onerosidade do processo de regularização fundiária e ambiental para a comercialização dos produtos. Na pesquisa foi possível identificar a execução de políticas públicas em benefício da sustentabilidade para agricultura familiar pela Prefeitura de Parauapebas com objetivo de fomentar produções rentáveis e sustentáveis.

Abstract The aim of the present study was to evaluate the swallowing patterns of the tongue using B-mode sonography. A total of 65 patients aged between eight and 35 years were enrolled in the study including 25 controls. The swallowing patterns of the 40 patients were divided into groups of ten normal, 12 inconsistent, and 18 abnormal. Eight patients with a swallowing abnormality had Angle Class I occlusions, two had Class II, and the remaining ten patients had Class III. The majority of abnormal or inconsistent swallowing patterns were found in cases of mandibular prognathism. Quantitative data was not analyzed in this study. The results of this study show that B-mode sonography, being a non-invasive procedure permitting direct visualization of the movements of the tongue in both coronal and sagittal planes, can be used with certainty for diagnosing swallowing abnormalities.

Abstract Pigmentation is both the normal and abnormal discoloration of oral mucous membrane. Pigmentation has multifactorial etiology. Most of the pigmentation is physiologic but sometimes it can be a precursor of severe diseases. Melanin pigment irregularities and color changes of the oral tissues could provide significant diagnostic evidence of both local and systemic disease. The differential diagnosis, clinical, etiology, and histopathological features of pigmentation are discussed and the current literature is reviewed. Citation Çiçek Y.

Abstract Aim The purpose of this clinical report is to present a description of the prosthetic rehabilitation of a bilateral complete maxillectomy patient using a two piece magnetically connected prosthesis. Background A complete bilateral maxillectomy defect presents a considerable reconstructive challenge for the prosthodontist. It results in devastating effects on cosmetic, functional, and psychological aspects of the patient. Report A 46-year-old woman reported with a chief complaint of missing teeth in the upper jaw. Her primary concerns were a poor facial appearance, inability to chew food, and regurgitation of the food into the nasal cavity. She was diagnosed with carcinoma of the maxillary sinus, for which a bilateral maxillectomy was done followed by post surgical radiation therapy. The prosthetic treatment objectives were to separate the nasal and oral cavities, restore the mid-facial contour, and improve her masticatory functions by providing a full complement of maxillary teeth using a two-piece connected hollow obturator prosthesis connected by a magnet. Summary Insertion and removal of a large prostheses used for rehabilitation of midfacial defects requires good neuromotor coordination and an adequate mouth opening. Because these factors were problematic for this patient, the treatment plan was to fabricate a two piece magnetically connected prosthesis. After fabrication and insertion of the prosthesis, the fit between two sections was evaluated and instructions for insertion, removal, and maintenance of the obturator were given. The patient's speech, masticatory efficiency, and swallowing dramatically improved after insertion. Citation Chandra TS, Sholapurkar A, Joseph RM, Aparna IN, Pai KM.

Rationale: Cytomegalovirus (CMV) infection is a common cause for neurodisability among poor populations in developing countries, including Bangladesh. Some studies have shown that ganciclovir therapy is effective in reducing neurodevelopmental morbidity; while others remain equivocal.Objective : The objective of this study was to evaluate neurodevelopmental outcome of children with symptomatic CMV treated with ganciclovir compared to matched control.Methods: Out of 218 children seropositive for CMV admitted into the neurology ward between 2003-2006, 91 were treated with intravenous ganciclovir for 2-3 weeks; of whom 43 came for follow-up at an interval of 3 months to 1 year. At each visit neurodevelopmental status was recorded for cognition, vision and hearing. 41 untreated age-matched cases with follow-up records were retrospectively enrolled as control.Results: Among treated children compared to untreated controls, there was significant improvement in hearing (58% vs. 27%; p value=.012). Improvement remained consistent, without statistical significance, for vision (53% vs. 39%; p value=.071)) and cognition (51% vs. 54%; p value=.344).Conclusion: Ganciclovir treatment improved neurodevelopmental outcomes of very young children with symptomatic CMV infection. In a country where limited resources are available for children with disability, early recognition and treatment of CMV infection is recommended.DOI: http://dx.doi.org/10.3329/bjch.v35i3.10498 Bangladesh J Child Health 2011; Vol 35 (3): 97-101

Testo completoAbstract (sommario):
Abstract The aim of the study was to determine how the morphology of occlusal surfaces might affect occlusal loading that is transferred to the tooth apex. Photoelastic methods were used to assess apical stress generated by seven variations of occlusions. A test assembly with a 2 kg weight was applied to teeth to create a vertical load. By analyzing the direction and magnitude of the apical principle stress under the polar light that was measured at the apexes of mandibular teeth, the occlusal loading position of each tooth and its direction was obtained based on general mechanical principles. It was found distal incline planes (or slopes) of cusps and lingual incline planes (or slope) of buccal cusps of mandibular posterior teeth carried the greatest occlusal load in normal occlusion. In the other six variations of occlusion presented in this study, the principle apical stresses changed more or less as a result of the different occlusal contact relationships. The magnitude of principle apical stress increased considerably in the flat surface occlusion because of the lack of distribution of occlusion loading by the smooth dentition surface. It is concluded the occlusal surface morphology has a significant effect on the direction and magnitude of apical stress. To establish a suitable relationship of occlusion that can conduct favorable occlusal loading physiologically is very important. Citation Wang M, Zhang M, Zhang J.

Abstract The purpose of the present study was to determine the mean and standard deviation of eruption for primary dentition in children from Saudi Arabia and to compare it with another sample of full-term children who are clinically healthy between the ages of 4-40 months. The results were significantly different from available literature on eruption patterns in children. Moreover, there is a slightly delayed eruption of primary teeth in Saudi children when compared to Caucasians. However, the order of eruption of primary teeth was the same as reported in other studies. Citation Al-Jasser NM, Bello LL. Time of Eruption of Primary Dentitionin Children from Saudi Arabia.

Gagnon, B., Ziadi, N. and Grant, C. 2012. Urea fertilizer forms affect grain corn yield and nitrogen use efficiency. Can. J. Soil Sci. 92: 341–351. Controlled-release urea may be a good management strategy to increase the efficiency of N fertilizers. In a 3-yr study (2008–2010) conducted on a clay soil near Quebec City, Canada, we compared the effect of polymer-coated urea (PCU), nitrification inhibitor urea (NIU), dry urea and urea ammonium nitrate 32% (UAN) on corn yield, plant N accumulation and soil NO3-N remaining at harvest. Corn was fertilized with urea and PCU at 50, 100 and 150 kg N ha−1 in addition to an unfertilized control (0 N), and NIU and UAN at 150 kg N ha−1. Urea, PCU, and NIU were pre-plant broadcast whereas UAN was side-banded at the six-leaf stage of corn. Response to N fertilization occurred in all years, but the magnitude of the response varied with years. In wet years (2008 and 2009), PCU and NIU resulted in higher grain yield than urea, but the increase was greater for PCU (+0.8 to 1.6 Mg ha−1) than for NIU (+0.3 to 0.6 Mg ha−1). In a dry year (2010), no significant difference was found between urea, PCU and NIU. Yields and apparent N recovery were comparable for PCU and UAN except in the dry year, when plant N accumulation was much higher for the UAN treatment. At harvest, soil NO3-N was increased by PCU in all years. Economic analysis revealed that despite 30% higher cost, PCU gave comparable net returns at equivalent N rate than UAN in wet years. We conclude that controlled-release urea, particularly PCU, would be an additional option to farmers instead of sidedressed UAN application for fertilizing corn grown in eastern Canada.

Abstract Aim The aim of this report is to describe the restorative treatment of an 18-year-old patient diagnosed with autossomal recessive hypocalcified-hypoplastic amelogenesis imperfect (AI). Background Esthetic and functional rehabilitations in AI cases are challenging and should consider individual aspects, such as age, socioeconomic status, AI type, and intraoral condition. Report AI was diagnosed in an 18-year-old patient. Summary Considering the short length of crowns and roots, patient life expectancy, minimal invasiveness, amount of treatment time required, and lower costs, oral rehabilitation with overdentures provided an adequate functional and esthetic rehabilitation of the patient. Clinical Significance This report demonstrated overdentures to be a viable, relatively inexpensive, and noninvasive treatment choice of a patient with AI with concerns about treatment longevity, invasiveness, cost, esthetics, and long-term maintenance.

Abstract The aim of this study was to identify the perceived sources of stress among dental students, dental hygiene students, and dental technology students enrolled at Jordan University of Science and Technology (JUST). The modified dental environment stress questionnaire was administered to 183 students. The perceived stressors varied between major and year. Dental students gave high scores for examinations, reduced holidays, inadequate time for relaxation, fear of failure, completing clinical requirements, and differences in opinion between staff. Dental hygiene students gave the highest scores for uncertainty about the field of study as future career, examinations, inadequate clinical training and supervision, inadequate relaxation, and discrimination between students. Dental technology students also gave high scores for uncertainty about future career, examinations, approachability of the staff, inadequate relaxation, and completing requirements. Females are more stressed than males with regard to personal factors. Dental technology and/or dental hygiene students have significantly higher scores than dental students in 12 items. Students who reported their first choice of study was not their current field of study showed more stress concerning their future careers. The high scores reported for some stressors among students emphasize the need to address student's concerns. Citation Al-Omari WM. Perceived Sources of Stress within a Dental Educational Environment.

Abstract Objective The aim of the present study was to examine: (1) the prevalence of tooth loss in persons living in community dwellings and (2) the strength of the association identified between tooth loss experience and the psychosocial factors of lifestyle, stress, and anxiety. Material And Methods A cross-sectional study was carried out in a convenience sample where data were collected by means of self-administered questionnaires of lifestyle and psychosocial factors (stress and anxiety) and a clinical examination. A total of 516 subjects aged 14-30 years of age were included in the study. Subjects had a visual dental examination. Prevalence and mean of tooth loss were calculated excluding third molars, and their related factors were adjusted in a binary logistic regression. Results Mean age of participants was 17.4±3.0 years; 45.5% were men. The prevalence of tooth loss (when at least one tooth was lost) was 20.5%. Among the 516 persons, a total of 201 teeth were lost with a mean tooth loss 0.39±0.95 overall. Mean tooth loss in subjects with at least one missing tooth was 1.90±1.26 teeth. Results adjusted by anxiety in the multivariate logistic regression model showed tooth loss was associated with lifestyle (OR=1.95, 95% CI=1.17 – 3.24), age (OR=2.65, 95% CI=1.64 – 4.26), and Angle's malocclusion II and III (OR=2.86; 95% CI=1.67 – 4.90). A slight association toward tooth loss was observed (p<0.10) in the sex and stress variables. Conclusions Lifestyle and tooth loss have a substantial association. According to age group, these results suggest tooth loss is an oral health problem in the study population.

Abstract Purpose The purpose of this study was to evaluate three different methods (ST: Standard technique; PS: Pea-size; TT: Transverse technique) for dentifrice use in children between 5-7 years of age, as well as to compare the amount of dentifrice dispensed by using tubes with different orifices (cresent or round shaped). Methods and Materials One hundred children who dispensed the dentifrice themselves were asked to apply the quantity of dentifrice they usually used (ST or TT) (Phase-I). In Phase-II they were instructed to apply a PS amount, and in Phase III the TT was demonstrated. Statistical analysis was obtained by using Anova and t-test. Results Most of the children (82 patients) preferred to use the ST rather than the TT (18 patients). A decrease in the dentifrice amount was obtained with both of the shaped orifices after the instruction of PS or demonstration of the TT (p< 0.05). It was observed the amount of dentifrice dispended decreased when a cresent-shaped orifice was used. Conclusion Children usually preferred to use the ST rather than the TT before the instruction or demonstration by the operator. The amount of dentifrice dispensed generally decreased when a dentifrice tube with a crescentshaped orifice was used. Citation Ölmez A, Tüfekciogğlu D, Erdemli E.

Abstract Aim The aim of this study was to assess the frequency of nine tongue conditions and evaluate their relationship to oral hygiene status and personal habits in a Northern Iranian population. Methods and Materials This descriptive study evaluated 1901 healthy subjects (1142 women, 759 men) >12 years who were referred to the Dental Faculty of Babol University during a period from February 2005 to July 2006. A questionnaire was designed according to the aims of the study. Each subject completed the questionnaire and received a complete dental and oral examination. Statistical analysis was performed using SPSS software and Chi-square and Fisher's exact probability tests. Results Six hundred seventy-two (35.3%) of 1901 subjects had tongue lesions with a frequency of 38.6% in women and 47.7% in men which was statistically significant (P<0.0001). A strong association was found between tongue lesions and smoking (p<0.0001), black tea drinking (p=0.021), and poor oral hygiene (p<0.0001). Hairy tongue (p<0.0001), coated tongue (p<0.0001), and fissured tongue (p=0.014) conditions were significantly higher in males, while crenation of the tongue was more frequent in women (p<0.0001). Conclusion This epidemiologic survey of adult dental outpatients of Northern Iran assessing tongue conditions and lesions found the frequency of these conditions in 47.7% of males and 38.6% of females in this population. Tongue conditions and lesions were more frequent among smokers, black tea drinkers, and those with poor oral hygiene. The results of this epidemiological survey can only be interpreted for the population studied and as such cannot be generalized to the wider population of Iran, but future studies should be designed to assess the frequency of these conditions on a countrywide basis. Clinical Significance The results of this study suggest efficient oral hygiene programs and encouraging people to drink less tea and quit smoking may reduce tongue lesions in adult dental outpatients in Northern Iran.

Testo completoAbstract (sommario):
Проведено сравнительное исследование токсического действия ионов свинца, кадмия и меди на организм почвенной нематоды Caenorhabditis elegans линии дикого типа N2. Двухчасовая экспозиция нематод к растворам Pb(NO3)2, Cu(NO3)2 или Cd(NO3)2 в концентрации 10 и 20 мМ повышала чувствительность моторной программы плавания, индуцированного механическим стимулом, к агонисту никотиновых рецепторов ацетилхолина левамизолу в концентрации 2, 4 и 8 мкМ. Повышение чувствительности локомоции C. elegans к левамизолу проявлялось в снижении доли нематод, сохранивших способность поддерживать плавание в течение 10 с после стимула. В условиях экспериментов наиболее сильное токсическое действие на нематод оказывал нитрат меди, наименее токсичным был нитрат свинца. 30-минутная экспозиция C. elegans к Pb(NO3)2, Cu(NO3)2 или Cd(NO3)2 в концентрации 10 и 20 мМ с последующим восстановлением нематод в течение 24 часов на среде выращивания с бактериями также повышала чувствительность моторной программы плавания к левамизолу. Выявленное повышение чувствительности локомоции C. elegans к левамизолу после кратковременной экспозиции к ионам Pb2+, Cd2+ и Cu2+ не может быть следствием накопления этих токсикантов во внутренней среде из-за наличия у нематод кутикулы, ограничивающей проникновение токсикантов во внутреннюю среду организма. Кратковременная экспозиция нематод к высоким дозам Pb(NO3)2 могла вызвать гибель части дофаминергических нейронов, что привело к снижению уровня эндогенного дофамина. Снижение уровня эндогенного дофамина, в свою очередь, могло привести к повышению содержания эндогенного ацетилхолина и, как следствие, повышению чувствительности никотиновых холинорецепторов к их агонисту левамизолу. Возможным объяснением выявленного в работе повышения чувствительности локомоции C. elegans к левамизолу после кратковременного действия Cd(NO3)2 и Cu(NO3)2 может быть изменение функций холинергических и ГАМКергических нейронов в системе нейронов, участвующей в реализации моторной программы плавания нематод.

Abstract Aims The aim of the present study was to investigate the incidence of impacted mandibular canines, the associated pathology of these teeth, and to classify them. Methods and Materials This is a retrospective cohort study of 5022 panoramic radiographs taken of patients who presented to the Oral and Maxillofacial Surgery Service of the Faculty of Dentistry at Ataturk University in Erzurum, Turkey between January, 1998 and March, 2006. The panoramic radiographs and clinical data were reviewed. Observations were made on the status of missing permanent mandibular canines; retained deciduous canines; side and number of mandibular canines; sex and age of patients; and any other associated pathology or symptoms as well as treatment methods employed. Results The incidence of mandibular canine impaction is 1.29% in the 5022 individuals of this Turkish subpopulation. A total of 65 patients had impacted mandibular canines with 33 being females and 32 males. In this study 41 impacted mandibular canines were extracted. Twenty-three canines were attached to bonded buttons for orthodontic eruption purposes. After surgical exposure, one impacted canine was transplanted and the others were left in place for observation. Conclusions Maxillary canine impaction is more frequent than mandibular canine impaction. Mandibular canine impaction incidence in this study was found higher than in the published literature to date. This result may be evidence of an actual increase of the number of impacted mandibular canine teeth among patients. Citation Yavuz MS, Aras MH, Büyükkurt MC, Tozoglu S. Impacted Mandibular Canines.

Проведено изучение возможной роли рецепторов дофамина DOP-1, DOP-2 и DOP-3 в модуляции чувствительности почвенной нематоды Caenorhabditis elegans к токсическому действию нитрата свинца. Эксперименты проводили с нематодами четырех линий: линия дикого типа N2 и мутантные линии LX636 (dop-1(vs101)X), LX702 (dop-2(vs105)V), LX703 (dop-3(vs106)X) с нуль-мутациями одного из генов рецепторов дофамина (dop-1, dop-2 и dop-3 соответственно). Нуль-мутации генов рецепторов дофамина DOP-2 и DOP-3 не вызывали достоверных изменений устойчивости поведения C. elegans к действию Pb(NO3)2 в концентрации 0.25–1.0 мМ. Нуль-мутация гена рецептора DOP-1 повышала чувствительность поведения C. elegans к ионам Pb2+ в течение 30–120-минутной экспозиции к токсиканту. Введение в среду инкубации дофамина в концентрации 8 мМ не оказывало существенного влияния на поведение C. elegans, но снижало чувствительность нематод линий с мутациями генов dop-1 и dop-3 к Pb(NO3)2. Дофамин в концентрации 4 мМ не оказывал достоверного влияния на локомоцию C. elegans всех четырех линий как сам по себе, так и при добавлении в среду с нитратом свинца. Нарушения моторной программы плавания у dop-1 мутантов могут быть следствием пониженного содержания эндогенного ацетилхолина в моторных нейронах в результате недостаточной DOP-1 дофаминергической трансмиссии. Снижение чувствительности dop-1 и dop-3 мутантов к Pb(NO3)2 при введении в среду инкубации 8мМ дофамина свидетельствует о том, что у C. elegans этих линий чувствительность к дофамину сохраняется.

Abstract About 40% to 50% of Down syndrome (DS) patients can have significant congenital heart defects such as patent ductus arteriosus, Tetralogy of Fallot, and septal defects. Patients with large septal defects may develop Eisenmenger syndrome (ES), which is defined by the cardiac septal defect and pulmonary hypertension coupled with a reverse right to left shunting of blood flow. DS patients that suffer from this condition require special considerations in the delivery of their dental care to prevent further medical complications or emergencies such as infection, cyanotic episodes, and thromboemboli. Collaboration with the cardiologist is also essential to ensure a complete and comprehensive pre-operative work up. The purpose of this article is to describe the dental management of DS patients with ES under general anesthesia. Citation Chung EM, Sung EC, Sakurai KL.

Abstract Background There are no published case reports that hematomas occur on the floor of the mouth as a result of periodontal surgery. Report These three case reports document post surgical hematoma formation on the floor of the mouth that pose problems with the diagnosis, prognosis, and patient management. All cases involved periodontal surgery where extensive reduction of tori and bony exostoses were required. Two cases resulted in hematomas in the floor of the mouth. However, a change in the post surgical management for a third case demonstrated possible prevention of hematoma formation. Summary Hematomas in the floor of the mouth can be a resolving post surgical phenomenon or a serious vascular insult to this region of the oral cavity. This report clarifies the diagnosis, prognosis, and the best management protocol through the presentation of three cases. Citation Mantzikos K, Segelnick SL, Schoor R.

Abstract Aim The purpose of this article is to describe a case of multiple giant cell lesions of the mandible that occurred in a 14-year-old girl with phenotypic characteristics associated with Noonan Syndrome (NS). Background NS is a dysmorphic disorder characterized by hypertelorism, short stature, congenital heart defects, short and webbed neck, skeletal anomalies, and bleeding diathesis. Report A 14-year-old girl with a previous diagnosis of NS (sporadic case) presented with multiple radiolucent lesions in the body and ramus of her mandible. Summary In terms of clinical behavior and the described radiographic characteristics, giant cells lesions with Noonan-like phenotype can be considered a form of cherubism. Therefore, surgical intervention is not necessary, but radiographic follow-up and observation is very important during the control and gradual regression of the lesions.

Abstract Abstract 4648 We have demonstrated the thrombopoietic effects of Chinese Medicine Dang Gui Bu Xue Tong (DBT), a formula composed of Radix Angelicae Sinensis and Radix Astragali in a thrombocypenic mouse model (Yang M et al, J Ethnopharm 2009). In this study, we further test the effect of polysaccharide (APS) from the root of Radix Angelicae Sinensis (APS) in in-vivo thrombopoiesis and in in-vitro megakaryocytopoiesis. A myelosuppression and thrombocytopenia mouse model was treated with APS (10 mg/kg/day), thrombopoietin (TPO) and saline as control. Peripheral blood cells from APS, TPO and vehicle-treated samples were then counted in different time-points. Using the colony-forming unit (CFU) assays, we determined the effects of APS on the hematopoietic stem/progenitor cells and megakaryocytic lineages. Analyses of Annexin V, Caspase-3, and Mitochondrial Membrane Potential were also conducted in megakaryocytic cell line M-07e. Lastly, the effects of APS on cells treated with Ly294002, a Phosphatidylinositol 3-Kinse inhibitor and the effect of APS on the phosphorylation of AKT were further studied in megakaryocytic cells. Our results showed that APS significantly enhanced the platelets and other blood cells recovery and CFU formation in this model. Morphological examination of bone marrows showed that APS treatment significantly increased the recovery of the megakaryocytic series and other hematopoietic progenitor cells. We observed the antiapoptotic effects of APS on M-07e cells. Addition of Ly294002 alone increases the percentage of cells undergoing apoptosis. In contrast, additional of APS to Ly294002-treated cells reversed the percentage of cells undergoing apoptosis. Furthermore, addition of APS significantly increased the phosphorylation of AKT. Our studies demonstrate that APS promotes platelet recovery in the mouse model and has anti-apoptosis effect in megakaryocytic cells. This effect is likely to be mediated by the PI3K/AKT pathway.

Abstract Aim The purpose of this article is to report a rare case of primary tuberculosis of the tongue. Background Tuberculosis is an infectious, chronic granulomatous disease that can involve almost any organ in the body, but primary lesions are usually confined to the lungs. Oral lesions are an infrequent occurrence in tuberculosis, and tuberculosis of the oral cavity is often a consequence of active pulmonary tuberculosis. Although primary tuberculosis in the oral cavity has been documented, it is a rare occurrence. Report A 42-year-old male patient presented with chief complaints of severe pain and ulceration on the ventrolateral surface of the left side of the tongue, measuring about 1.25×1.50 cm with surrounding erythema and induration of one-month duration. The ulcer was initially painless but became painful later with increased severity over time. The sore tongue caused difficulty in eating, drinking, swallowing, and even talking. The patient also complained of malaise for some duration, but there was no history of fever, cough, weight loss, and his bladder-bowel habits were normal. An excisional biopsy differentiated the lesion from squamous cell carcinoma and confirmed the diagnosis. Summary Even though primary tuberculosis in the oral cavity is a rare finding, it must be included in the differential diagnosis of mucosal lesions. This case provides a clinical example of the importance of this inclusion for the well being of the patient and for the community due to the communicable nature of the disease.

Abstract Objective To evaluate dentists’ prescription writing patterns and their appreciation of the characteristics of antibiotics. Design Evaluation of drug prescriptions written over a six-month period. Setting Dental Hospital, Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife, Nigeria. Subjects Retrospective analysis of 313 prescriptions written by dentists attending to outpatient dental patients. Results The total number of drugs on one prescription ranged from one to seven with Penicillins being the most commonly prescribed drug. Some prescriptions were found to be incorrect with regards to dose, frequency, and duration. Instructions as to the best time of administering drugs with regards to meals were not stated in any prescription. Conclusion Improvement through continuing education is desired on the part of prescribers to ensure a good standard of care and avoid practices that may increase antimicrobial resistance. Drug information services including side effects and drug interactions for professionals and consumers at the hospital is highly desirable. Citation Ogunbodede EO, Fatusi AO, Folayan MO, Olayiwola G.
