(1) Background: Periodontal instrumentation with dental curettes is associated with discomfort, fatigue, and musculoskeletal diseases. The goal of this study was to compare comfort, fatigue, and muscle work using three different curettes. (2) Methods: Eight hygienists each scaled three typodonts using the three different curettes. Curette A was a prototype with a novel adaptive design, Curette B had a conventional stainless-steel design, and Curette C featured a conventional silicon-covered handle. Time-based work in four muscles, comfort, fatigue, tactile feedback, grip and blade position, and pinch and grasp strength were recorded. Statistical analysis was performed using a General Linear Model (GLIM) and Tukey’s post hoc test. The level of significance was set at p < 0.05. (3) Results: Comfort, correct grasp, fingertip placement, and blade-to-tooth adaptation were significantly better with Curette A (p < 0.05). While pinch and grasp strength were significantly reduced post-instrumentation for Curettes B and C (p < 0.05), they remained unchanged for Curette A. Curette A required significantly less total muscle work and work in individual muscles, resulting in significantly less post-instrumentation fatigue than for Curettes B and C, but similar levels of tactile feedback (p < 0.05). (4) Conclusions: The ergonomic performance of a prototype adaptive periodontal curette was significantly better than that of two conventional instruments with rigid handle designs.

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.

Background: To compare fatigue, comfort, and muscle work associated with the use of two periodontal curettes during scaling: one with a novel adaptive design, the other with a conventional non-adaptive design. Methods: Twelve hygienists scaled a typodont using two Universal Barnhart 5/6 curettes: (1) a prototype featuring an adaptive silicone-covered handle (Curette A), and (2) a stainless-steel curette (Curette B). Surface Electromyography (sEMG) traced muscle work. Hand positions, fatigue, comfort, pinch, and grasp strength were recorded. Paired t-tests and a repeated measures ANOVA with covariates were tested for differences. The significance level was set at p < 0.05. Results: Curette A performed significantly better in all categories. Pinch and grasp strength and fatigue were significantly reduced post-instrumentation for Curette B. Curette A required significantly less (i) total muscle work and (ii) work in individual muscles. Comfort, correct grasp, and blade adaptation were significantly better using Curette A. Conclusions: A curette featuring a novel adaptive handle design demonstrated significantly improved ergonomic performance. Additional clinical studies are needed to solidify our understanding of the potential short- and long-term benefits of the novel curette handle design. Practical Implications: A novel adaptive curette handle design that enables the clinician to adapt the instrument across the index finger may reduce musculoskeletal burden and fatigue, as well as improve comfort during periodontal instrumentation.

In spinal surgery, ultrasonic bone curettes are considered unlikely to cause mechanical injury to the dura; however, there is little evidence to support this claim. We investigated the effect of direct contact with an ultrasonic bone curette on the dura and the protective effect of covering the dura with a cotton pattie using an excised porcine spinal cord. The ultrasonic bone curette was pressed against the porcine spinal cord with constant force and activated for 1 s, with or without covering the dura with a cotton pattie. The dural surface and cross-section were observed using electron and light microscopy. When the ultrasonic bone curette was applied directly against the dura, most specimens showed non-perforating dural injuries. However, none of the specimens showed dural perforation. Histological changes were also observed. The use of a cotton pattie reduced the occurrence of these changes, although it did not prevent them when ultrasonic vibration was applied with a large force. We considered ultrasonic bone curettes to have a low risk of dural perforation and, thus, to be a safe surgical device as long as they did not accidentally make strong contact with the dura.

Background: The aim of root debridement procedures in non-surgical periodontal treatment is the elimination of etiologic factors that cause periodontal disease, as well as the removal of cement affected by the disease. However, root debridement procedures for the treatment of periodontal diseases produce root surface irregularities that can adversely affect the healing of periodontal tissues. The objective of the present study is to evaluate the surface texture of a root after instrumentation, including an ultrasonic instrument, a Gracey curette, or a double Gracey curette. Methods: A total of 26 single-rooted teeth were used in this study; two specimens were used as controls, and the remaining 24 specimens were equally divided into three groups. Specimens from each group were then subjected to root planing using one of the following instruments: (1) an ultrasonic instrument; (2) a Gracey curette; or (3) a double Gracey curette. The control group was treated with no instrumentation. The extracted teeth were analyzed under a scanning electron microscope and graded in terms of the “roughness and loss of tooth substance index” and the “exposed dentin tubule index.” The SPSS (Statistical Package for Social Sciences) V.21 program was used to conduct a statistical analysis of the data obtained in this study. While evaluating the data, in addition to descriptive statistical methods (mean and standard deviation), a one-way analysis of variance (one-way ANOVA) was carried out to compare the quantitative data and evaluate normally distributed parameters between groups, while a post hoc multiple comparison test was carried out for subgroup comparisons. Results: There was no statistically significant difference between the roughness and material loss on the root surfaces in the samples treated with the ultrasonic instrument or the Gracey curette, and no exposed dentine tubules were observed. Meanwhile, it was observed that the double Gracey curette caused more roughness and material loss on the root surface, and exposed dentine tubules were observed in some samples. The time required for treatment using a double Gracey curette was significantly shorter than that required with the Gracey curette and ultrasonic instruments. Conclusions: The double Gracey curettes produced a relatively rougher root surface than the Gracey curettes or the ultrasonic instrument.

Object Unintended durotomies are a common complication of spine surgery and are often correlated with increased postoperative morbidity. Recently, ultrasonic bone curettes have been introduced in spine surgery as a possible alternative to the conventional high-speed drill, offering the potential for greater bone-cutting precision and less damage to surrounding soft tissues. To date, however, few studies have investigated the safety and efficacy of the ultrasonic bone curette in reducing the rates of incidental durotomy compared with the high-speed drill. Methods The authors retrospectively reviewed the records of 337 consecutive patients who underwent posterior cervical or thoracic decompression at a single institution between January 2009 and September 2011. Preoperative pathologies, the location and extent of spinal decompression, and the use of an ultrasonic bone curette versus the high-speed drill were noted. The rates of incidental durotomy, as well as hospital length of stay (LOS) and perioperative outcomes, were compared between patients who were treated using the ultrasonic bone curette and those treated using a high-speed drill. Results Among 88 patients who were treated using an ultrasonic bone curette and 249 who were treated using a high-speed drill, 5 (5.7%) and 9 (3.6%) patients had an unintentional durotomy, respectively. This finding was not statistically significant (p = 0.40). No patients in either cohort experienced statistically higher rates of perioperative complications, although patients treated using an ultrasonic bone curette tended to have a longer hospital LOS. This difference may be attributed to the fact that this series contained a statistically higher number of metastatic tumor cases (p < 0.0001) in the ultrasonic bone curette cohort, likely increasing the LOS for that patient population. In 13 patients, the dural defect was repaired intraoperatively. No patients who experienced an incidental durotomy had new-onset or permanent neurological deficits postoperatively. Conclusions The safety and efficacy of ultrasonic bone curettes in spine surgery has not been well established. This study shows that the ultrasonic bone curette has a similar safety profile compared with the high-speed drill, although both are capable of causing iatrogenic dural tears during spine surgery.

This study used scanning electron microscopy (SEM) to evaluate the morphology and adhesion of blood components on root surfaces instrumented by curettes, piezoelectric ultrasonic scaler and Er,Cr:YSGG laser. One hundred samples from 25 teeth were divided into 5 groups: 1) Curettes; 2) Piezoelectric ultrasonic scaler; 3) Curettes plus piezoelectric ultrasonic scaler; 4) Er,Cr:YSGG laser; 5) Curettes plus Er,Cr:YSGG laser. Ten samples from each group were used for analysis of root morphology and the other 10 were used for analysis of adhesion of blood components on root surface. The results were analyzed statistically by the Kruskall-Wallis and Mann-Whitney tests with a significance level of 5%. The group treated with curettes showed smoother surfaces when compared to the groups were instrumented with piezoelectric ultrasonic scaler and the Er,Cr:YSGG laser. The surfaces instrumented with piezoelectric ultrasonic scaler and Er,Cr:YSGG laser, alone or in combination with hand scaling and root planing, did not differ significantly (p>0.05) among themselves. No statistically significant differences (p>0.05) among groups were found as to the adhesion of blood components on root surface. Ultrasonic instrumentation and Er,Cr:YSGG irradiation produced rougher root surfaces than the use of curettes, but there were no differences among treatments with respect to the adhesion of blood components.

Periodontal scaling is the treatment approach most used to remove dental calculus, plaque, and altered cementum from root surface. During root decontamination, the instruments used leave the root rougher and more irregular. Objective: To verify the root surface after mechanical scaling with different Gracey curettes steel through SEM and superficial roughness analyses. Material and methods: Twelve teeth were embedded in acrylic resin. The teeth were instrumented with new Gracey curettes Gracey 5/6 from different brands. The groups (n=2) were divided into: control, no instrumentation (GC); carbon steel (CSN); stainless steel Neumar (SSN); stainless steel Millenium (SSM); premium steel Neumar (PSN); Hu-Friedy (HF). An area measuring 3 x 3 mm2 was marked on the distal surface of the root to guide the Reading of the root topography on SEM and rugosimeter. The data were analyzed by a single examiner previously calibrated. SEM analysis was based on scores of the root surface smoothness after scaling. We analyzed the parameters of mean roughness (Ra) and mean roughness deepness (Rz). SEM data were submitted to statistical analysis through Fisher’s exact test (p < 0.002) and roughness data by Anova followed by Student t test. Results: The quality of the active surface of the curette demonstrated by SEM and roughness analyses that it can exert difference in the result regarding to the homogeneity produced after the scaling of root surface. Group SSM demonstrated a homogenous root surface (score 0) in SEM and better smoothness in rugosimeter analysis. Conclusion: According to com the methodology used, the group of curettes that provided better smoothness of root surface after scaling was SSM.

During professional hygiene procedures, different instruments used may cause various damage to dental prostheses. Deplaquing and scaling with curettes and ultrasonic instruments may inadvertently increase the surface roughness of the material and the risk of future bacterial adhesion and/or also compromise the marginal seal of the prosthesis. Hence, the aim of this study was to assess the qualitative effects of two types of curettes and one piezoelectric instrument with a stainless-steel tip on three types of metal-free samples. After treating the samples with different instrumentations, they were analyzed using the scanning electron microscope and then underwent a qualitative microanalysis by using a spectroscopy machine. All the materials tested in this study have undergone significant changes of their superficial structure after instrumentation both with mechanical and manual instruments. Plastic curettes appeared to be less aggressive than the other instruments. Disilicate samples show a significantly lower degree of surface glazing erosion compared to the zirconia sample with all the instruments used.

O presente estudo teve por objetivo avaliar as características anatômicas das bifurcações radiculares, e compará-las às dimensões das pontas ativas das curetas de Gracey e Pádua-Lima. Foram utilizados 198 dentes, distribuídos entre primeiros e segundos molares superiores e inferiores, provenientes do Banco de Dentes da Universidade de Taubaté. Depois de codificados, os dentes foram fotografados por meio de uma câmera acoplada a um aparelho estereoscópio. As imagens foram digitalizadas por meio de um programa de captação de imagens (Pixel View) e avaliadas por meio de um programa de leitura (Image Tool). Nos dentes foram avaliados: a altura dos troncos radiculares, o ângulo de divergência e a distância interradiculares. Nos instrumentais foram avaliados o comprimento, a largura e a espessura das lâminas. Após análise estatística dos dados, os resultados obtidos mostraram que as bifurcações vestibulares de 2MS foram as que menos permitiram o acesso dos instrumentais avaliados, sendo as curetas Gracey acessíveis à maioria das bifurcações. As bifurcações mesiais e distais de molares superiores, por apresentarem maior distância interradicular e ângulos mais divergentes, são as que mais permitem acesso aos instrumentais avaliados. Baseados nestes resultados podemos concluir que as características anatômicas radiculares podem ser um fator de restrição à instrumentação periodontal.
The present study aimed to evaluate the anatomic characteristics of the root bifurcations and compare them with the active tips of the curettes of Gracey and Pádua-Lima. One hundred ninety eight teeth were used, distributed among first and second upper and lower molars, from the Teeth Bank of the University of Taubaté. After received a numerical code, the teeth were photographed by a camera attached to a stereomicroscope. The images were scanned through a capture image program (Pixel View) and evaluated through a software program (Image Tool for Windows 2.0). The length of the root trunk, the divergence angle between the roots and the inter-root dimensions in the bifurcation region were evaluated. In the instruments, characteristics as width, thickness and length of the curettes blade were analyzed. After the statistics analysis, the results obtained showed that the 2MS buccal bifurcations are those least allow access by the instruments evaluated, and the Gracey curettes had access of the majority of the bifurcations. The mesiais and distal bifurcations of upper molars, to have greater inter-root dimensions distance and divergent angles, are those that allow access to more instrumental evaluated. Based in those results, we can conclude that the roots anatomic characteristics can be a factor to restriction the periodontal instrumentation.

Resumo: O objetivo deste estudo foi avaliar o efeito da raspagem manual na superfície de conexões de implantes de titânio após o uso das seguintes curetas comercialmente disponíveis: 3i, Hu-Friedy, Premier, Prophy-Implant. As amostras foram nominadas ao acaso de A a G, e cada uma foi subdividida em quatro áreas para tratamento usando um diferente tipo de cureta. As amostras foram analisadas através de Microscopia Eletrônica de Varredura (MEV) e de Rugosímetro. Esta análise foi realizada antes e após os tratamentos propostos que consistiram de instrumentação com curetas repetindo-a 40 vezes em cada área simulando a quantidade de raspagens realizadas sobre um implante após 5 anos de uso (fase1). Um procedimento similar foi usado, nas mesmas áreas, simulando a quantidade de raspagens realizadas sobre um implante após 10 anos de uso. As superfícies das conexões foram reavaliadas. Os dados obtidos pelo rugosímetro foram estatisticamente analisados usando testes de Tukey, Duncan e Scheffe em níveis de probabilidade de 5% e 10%. Os resultados relativos à análise rugosimétrica demonstraram que não houve diferenças significantes entre os grupos (p<0,05). A textura de cada superfície nas fases avaliadas, registrada pelo MEV, corresponderam aos aspectos morfológicos da superfície dos abutments obtidos pela leitura rugosimétrica
Abstract: The aim of this study was to evaluate the effect of hand scaling on the surface of titanium abutments after using the following commercially available instruments: 3i, Hu-Friedy, Premier, Prophy-Implant. The samples were randomly categorized from A to G and each one of them was subdivided in 4 areas for treatment using the different curettes types. The samples were analyzed through scanning electron microscopy (SEM) and the rugosimeter. This analysis was taken before and after the treatments proposed that consisted of repeated instrumentation (40 times each area) to simulate a 5 year old implant (phase 1). After phase 1, a similar procedure was used in the same areas in order to simulate a 1 O-year old implant. The abutment surfaces were reevaluated by SEM and rugosimeter. The data obtained by rugosimeter were statistically analyzed using Tukey, Duncan and Scheffe test at 5 and 10% levels of probability. The results indicated differences (p<0.05) between the control area corresponding to the Hu-Friedy instrumentation area and the Premier group areas after phase 1. After phase 2, the results regarding to the rugosimeter analysis demonstrated that there were no significant differences among the groups (p<0.05). The texture of each surface, registered by SEM, in the evaluated phases corresponded to the data obtained by the rugosimeter

O presente trabalho teve por objetivo avaliar em fotomicrografias obtidas em microscópio eletrônico de varredura (MEV) o ângulo de corte de curetas de Gracey 5-6 em três níveis: afiação de fábrica, após ficarem sem corte e após serem reafiadas utilizando nove diferentes técnicas padronizadas de afiação: 1- face lateral da cureta contra a pedra Arkansas plana; 2- face coronal e posteriormente a lateral contra a pedra Arkansas plana; 3- pedra de Arkansas plana contra a face lateral da cureta; 4- cone de óxido de alumínio a baixa rotação contra a face coronal e em seguida a face lateral da cureta; 5- face lateral da cureta com pedra Arkansas 299; 6- face lateral da cureta com o aparelho padronizador Hu-Friedy; 7- face coronal da cureta com ponta de videa; 8- face coronal da cureta com ponta de videa e em seguida a face lateral com pedra de Arkansas plana; 9- afiação da face coronal com ponta de videa e em seguida pó abrasivo e roda de feltro rotatória na face lateral da cureta. Foram tomadas fotomicrografias (350X) do ângulo de corte e posteriormente avaliadas por um examinador calibrado através do índice do ângulo de corte. A analise estatística de Kruskal Wallis e comparações múltiplas mostraram que as técnicas 1 e 2 foram as melhores técnicas de afiação seguidas das técnicas 6, 5 e 8. As piores técnicas foram a 7, 9, 4, 0 e 3. A reafiação da face coronal das curetas produziu a formação de projeções metálicas não funcionais no ângulo de corte e finalmente não houve diferenças entre a afiação do extremo par e ímpar dos instrumentos em nenhuma das técnicas de afiação utilizadas.
A micrographs obtained by a scanning electron microscope (SEM) were used to evaluated the gracey 5-6 cutting edges as the come from manufacture, after they had been dull and after they were resharpened by several standard techniques: 1- lateral surface over a flat Arkansas sharp stone; 2- coronal surface and the a lateral surface over a flat Arkansas sharp stone; 3- lateral surface by passing a flat Arkansas sharp stone; 4- rotatory aluminum oxide stone over a coronal surface and then over a lateral face; 5- lateral surface by passing an Arkansas 299 stone; 6- lateral surface on Hu-Friedy sharp divice; 7- coronal surface by a Whittler Neivert Device; 8- coronal face by a Whittler Neivert Device and the a lateral surface over a flat Arkansas sharp stone; 9- coronal surface with a Whittler Neivert Device and a rotating, impregnated, felt wheel on the lateral surface. The cutting edges was blindly evaluated on micrographs (X350) by one calibrated examiner (cutting angle index). A statistical analysis showed that techniques 1 and 2 were the best ones followed by a 6, 5 and 8 techniques. The worst techniques were a 7, 9, 4, 0 and 3. Resharpened on the coronal face of curettes generated a non functional wire edges on the cutting edge angle and there were not differences between the paired and unpaired extreme of the instruments resharpened.

Resumo: O presente trabalho teve por objetivo avaliar em fotomicrografias obtidas em microscópio eletrônico de varredura (MEV) o ângulo de corte de curetas de Gracey 5-6 em três níveis: afiação de fábrica, após ficarem sem corte e após serem reafiadas utilizando nove diferentes técnicas padronizadas de afiação: 1- face lateral da cureta contra a pedra Arkansas plana; 2- face coronal e posteriormente a lateral contra a pedra Arkansas plana; 3- pedra de Arkansas plana contra a face lateral da cureta; 4- cone de óxido de alumínio a baixa rotação contra a face coronal e em seguida a face lateral da cureta; 5- face lateral da cureta com pedra Arkansas 299; 6- face lateral da cureta com o aparelho padronizador Hu-Friedy; 7- face coronal da cureta com ponta de videa; 8- face coronal da cureta com ponta de videa e em seguida a face lateral com pedra de Arkansas plana; 9- afiação da face coronal com ponta de videa e em seguida pó abrasivo e roda de feltro rotatória na face lateral da cureta. Foram tomadas fotomicrografias (350X) do ângulo de corte e posteriormente avaliadas por um examinador calibrado através do índice do ângulo de corte. A analise estatística de Kruskal Wallis e comparações múltiplas mostraram que as técnicas 1 e 2 foram as melhores técnicas de afiação seguidas das técnicas 6, 5 e 8. As piores técnicas foram a 7, 9, 4, 0 e 3. A reafiação da face coronal das curetas produziu a formação de projeções metálicas não funcionais no ângulo de corte e finalmente não houve diferenças entre a afiação do extremo par e ímpar dos instrumentos em nenhuma das técnicas de afiação utilizadas.
Abstract: A micrographs obtained by a scanning electron microscope (SEM) were used to evaluated the gracey 5-6 cutting edges as the come from manufacture, after they had been dull and after they were resharpened by several standard techniques: 1- lateral surface over a flat Arkansas sharp stone; 2- coronal surface and the a lateral surface over a flat Arkansas sharp stone; 3- lateral surface by passing a flat Arkansas sharp stone; 4- rotatory aluminum oxide stone over a coronal surface and then over a lateral face; 5- lateral surface by passing an Arkansas 299 stone; 6- lateral surface on Hu-Friedy sharp divice; 7- coronal surface by a Whittler Neivert Device; 8- coronal face by a Whittler Neivert Device and the a lateral surface over a flat Arkansas sharp stone; 9- coronal surface with a Whittler Neivert Device and a rotating, impregnated, felt wheel on the lateral surface. The cutting edges was blindly evaluated on micrographs (X350) by one calibrated examiner (cutting angle index). A statistical analysis showed that techniques 1 and 2 were the best ones followed by a 6, 5 and 8 techniques. The worst techniques were a 7, 9, 4, 0 and 3. Resharpened on the coronal face of curettes generated a non functional wire edges on the cutting edge angle and there were not differences between the paired and unpaired extreme of the instruments resharpened.

Abstract What Goes Around, Comes Around The story most frequently told by the Greeks about the beginning of dancing upon the earth—a story which became a part of Greek mythology—went as follows: In the early days of the world, before the race of man peopled the land, the Titan Rhea, wife of Cronus, taught the art of the dance to the Curetes, sons of Earth, who dwelt in the island of Crete, and to the Corybantes, who lived in Phrygia, in Asia Minor. This act stood Rhea in good stead later. Cronus, so the legend goes, habitually devoured his children at birth. Rhea fled to Crete and there her youngest son, the god Zeus, was born. Rhea hid Zeus in a cave and gave Cronus, instead of the child, a stone wrapped in swaddling clothes. Cronus swallowed the stone, and Rhea placed the baby in the care of the Curetes. They, to prevent Cronus from hearing the cries of Zeus, danced over him a wild, noisy, leaping dance, in which they shouted lustily and beat their swords against their shields. Legend says that they later became priests of Zeus and that they and their descendants continued their dances for centuries, as cult rituals.

Abstract Abortion can occur both spontaneously and electively. An abortion can be performed either medically or surgically. Medical abortions are usually managed with medications such as methotrexate, mifepristone, and misoprostol. Surgical abortions are performed with a manual vacuum aspirator (MVA), metal curette, a suction device, or any combination of these. Of note, 5% of all pregnancy-related maternal deaths are associated with either an elective or a spontaneous abortion. These maternal deaths are usually linked to sepsis and/or hemorrhage. The anesthetic considerations are dependent on the active issues that present when the patient enters the operating suite. The most concerning of them is the rapid management of hemorrhage and infection.
