ABSTRACT The endodontic triad consists of cleaning and shaping, disinfection and obturation. Success of root canal therapy in primary teeth is mainly achieved by thorough removal of debris and necrotic tissue. However, complete elimination of bacterial contaminants as well as necrotic debris require adjunctive use of root canal irrigants along with mechanical instrumentation. As we know from literature that none of the available irrigating solutions alone provides all the ideal requirements. Studies have shown that a combination of two or more irrigating solutions in a specific sequence will help to achieve optimal irrigation. This review article mainly highlights the mechanism of action, safety and biocompatibility of currently used irrigation solutions and also the other materials that can be used as a potent irrigants, their advantages and limitations in future of endodontics.

Full textAbstract:
Apex of root is of great interest for endodontists mainly because of different stages involved in its development and the surrounding tissues. Mandibular molars normally consists of 2 roots, one mesial and one distal. About common occurrence, 2 canals are found in mesial root and 1 canal in the distal root. The patient was diagnosed with symptomatic irreversible pulpitis. After cleaning and shaping, the next step is obturation. Lateral canals are complex findings in the apical third of root which is characterized as a lateral canal deviating from the main canal. Normally, this lateral canal is not part of the standard root canal procedure due to the complexities, but sometimes obturation might be possible, which might affect the long-term prognosis of the tooth. Advanced skills are required to attempt and complete obturation of the lateral canal which might be a difficult task for the general practitioners.

Full textAbstract:
Effective shaping and cleaning of root canals are essential for the success of endodontic treatment. Due to the complex anatomy of root canal spaces, the use of various instrumentation techniques alone is not effective in producing bacteria-free root canal spaces. Irrigation, disinfectants, rinses, and intervisit medications are used in conjunction with the mechanical instrumentation to ensure the success of endodontic treatment. Sodium hypochlorite (NaOCl), a halogenated compound, is routinely used to irrigate the root canal during endodontic treatments. NaOCl has been known for its antibacterial action, proteolytic and dissolution capacity, and debridement properties. NaOCl, however, can alter the composition of dentin and hence its interaction with the adhesive resins used to bond the restorative materials to treated dentin. This review therefore covers in depth the action of NaOCl on dentin-adhesive resin bond strength including both enhancement and reduction, then mechanisms proposed for such action, and finally how the adverse action of NaOCl on dentin can be reversed.

Full textAbstract:
Nickel-titanium (NiTi) usage is associated in endodontics with some complications including canal transportation. Centering ability of a NiTi file is the ability to stay centered in the root canal system during instrumentation. Any undesirable deviation from the natural canal path is indicated as canal transportation. A possible strategy to improve the centering ability of NiTi instruments is the pre-enlargement of the coronal third of the root canal to minimize coronal interferences. This procedure is known as coronal flaring. The aim of this study was to perform a micro-computed tomographic (micro-CT) evaluation of the effect of coronal flaring on canal transportation and centering ability of two heat treated nickel-titanium rotary instruments, 2Shape (Micro Mega, Besançon, France) and HyFlex CM (Coltène Whaledent, Altstätten, Switzerland). Thirty extracted mandibular molars with two independent mesial canals were selected and randomly instrumented (n = 15 canals) with One Flare (Micro Mega, Besançon, France) before HyFlex CM, HyFlex CM (without coronal flaring), One Flare before 2Shape and 2Shape (without coronal flaring). One Flare (Micro Mega, Besançon, France) was introduced 4 mm below the canal entrance for canals prepared with coronal flaring. HyFlex CM and 2Shape were used accordingly to manufacturers’ instructions. New files were used for each canal. During and after instrumentation, irrigation procedures were performed. Micro-CT images were obtained pre- and post-preparation to measure and record root canal transportation and centralization. They were reconstructed from root apex to canal orifices, generating approximately 1000 sections per specimen. The anatomical thirds were determined by dividing the number of cross-sectional slices by three. Root canal transportation and centralization were determined by Gambil method, and the mean values were analyzed by repeated measures analysis of variance followed by multiple comparisons of Bonferroni to compare the different instrumentations procedures and the root thirds (p < 0.05). As for root canal transportation, 2Shape reported significantly higher values compared to HyFlex CM in the cervical region independently from the coronal flaring. In the apical region, 2Shape caused significantly minor canal transportation when used with coronal flaring with compared with the absence of coronal flaring. Regarding the centralization, HyFlex CM showed higher values than 2Shape in the cervical, independently from coronal flaring. In the apical region, 2Shape with coronal flaring exhibited significant major centering ratio, compared with not. Within the limitations of this study, coronal flaring reduced canal transportation and improved centralization of the 2Shape files in the apical section while it had no significant influence on shaping ability of the HyFlex CM instruments. Coronal flaring could represent a valid strategy to improve the shaping ability of NiTi files knowing that its benefit could be influenced by the shaping file used.

ABSTRACT The main objective of an endodontic treatment is thorough shaping and cleaning of the root canal system, with the aim to obtain a fluid tight seal by a biocompatible obturating material. Complex unusual root canal morphology is an often-occurring phenomenon. Knowledge and understanding the unusual root canal morphology predicts the successful outcome in endodontic treatment. One such variant root canal morphology is the ‘S’ shaped root canal. The self-adjusting file (SAF) is a hollow compressible file made up of nickel-titanium lattice. The new concept associated with the SAF is that it adapts itself to the anatomical shape of the root canal and performs mechanical shaping and chemical cleaning with continuous irrigation simultaneously. This case report discusses endodontic treatment of a maxillary second premolar with a ‘S’ shaped root canal and its successful management with the SAF.

Full textAbstract:
The main goal of endodontic treatment is an effective cleaning and shaping of the root canal in order to eliminate bacteria from the canal system and prevent the occurrence of apical periodontitis. Adequate choice of instruments and preparation techniques significantly reduce the number of bacteria in the canal system prior to obturation. Studies have confirmed that canals instrumented to acceptable apical diameters provide significantly lower number of bacteria even without the use of irrigation. Application of rotary instruments, such as BioRaCe, provides biologi- cally appropriate diameter in the apical portion of the canal and thus a lower number of residual bacteria to ensure safe and effective obturation.

Aim: The aim of this case report is to present a series of anatomical variations and endodontic treatments in four two-canal mandibular premolar teeth and three rooted three-canal maxillary second premolar teeth with root canal treatment indications identified via clinical and radiographic examinations.
The success of root canal treatment is achieved with a thoroughly examined root canal morphology that has been accurately determined radiographically and clinically before adequate shaping, irrigation, and hermetic filling procedures. Root canals that are not found or not adequately disinfected can cause root canal treatment failure and complications, such as pain, swelling, or persistent fistula, also known as flare-up, after treatment.
Canal variations in the teeth were detected via periapical radiographs during the root canal instrumentation stage.
Methodology: The endodontic treatments of four two-canal mandibular premolar teeth and one triple-rooted three-canal maxillary second premolar with root canal treatment indications were described.
Conclusion: To achieve full success in root canal treatment, anatomical variations should be examined in detail before and during treatment, and treatment should be completed with appropriate techniques.

Full textAbstract:
Introduction: In root canal therapy, the cleaning and shaping of canals are routinely applied by clinicians in order to remove microorganisms. Eradicating bacteria from the root canal system plays a crucial role in long-term success; however, it is not always easy to disinfect root canals properly because of their complicated anatomy and bacterial load. Achieving an optimally disinfected root canal environment requires adjunctive antibacterial therapeutic methods. High-power laser utilization as an adjunctive strategy to conventional treatment is a relatively new approach that helps clinicians. Methods: This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. Online databases, namely Web of Science, PubMed/MEDLINE, Scopus, and Cochrane Library, were searched electronically regarding lasers and endodontic treatments. Appropriate studies were included according to the inclusion/exclusion criteria. Results: Among 504 obtained studies by search, 48 were considered for a detailed analysis. Ten articles performed in vivo evaluation, while nine assessed the effect of lasers on artificial models, and 29 conducted ex vivo experiments on extracted teeth. When the diode laser, the most frequently used laser, was utilized as an adjunct therapy after NaOCl irrigation, it killed more bacteria than conventional irrigation with NaOCl. Laser-activated irrigation (LAI) with the Er, Cr: YSGG laser and NaOCl disinfects the root canal effectively. Also, photon-induced photoacoustic streaming (PIPS) with Er: YAG and NaOCl exhibited a high bactericidal effect and deep tubular penetration. Conclusion: High-power laser utilization, considering proper case selection and method, can assist in root canal treatment of infected teeth.

The aim of this study was to evaluate apical sealing after root canal treatment using two different rotary instrumentation techniques and two thermoplastic root canal filling techniques. The study was performed in 115 human extracted mandibular premolars. After coronary access the apical foramen was opened with a # 15 K file 1 mm beyond the apex. Cleaning and shaping was subsequently carried out at the working length, 1 mm from the apex, with ProFile .04/.06 system (Dentsply/Maillefer), Quantec (Analytic Endodontics/Kerr) or by the step-back technique with 1% sodium hypochlorite solution as irrigating solution. The root canals were filled with Thermafil (Dentsply/Maillefer) or Microseal (Analytic Endodontics/Kerr) or by lateral condensation technique using AH Plus sealer (epoxy type). The teeth were immersed in 2% methylene blue under vacuum. Then, they were longitudinally sectioned. The results showed that the association of Profile and Thermafil Plus provide the best results (p<0.05). In conclusion, the association of different rotary instrumentation techniques and different filling systems influenced the apical sealing.

Manufacturers are constantly developing new products to optimise endodontic treatment. These newer file systems are often associated with increasing expenditure of instrumentation and can affect the cost effectiveness of root canal treatment. Recently, companies have emerged that claim to have successfully reproduced many of the more established endodontic file systems manufactured by Dentsply Sirona (Ballaigues, Switzerland). EdgeEndo (Albuquerque, New Mexico, USA) and PacDent (Brea, CA, USA), which manufacture files similar in design to that of Dentsply Sirona, claim that they are similar and sell them at a lower price. A performance comparison of the replica file systems to their original is of clinical importance. The aim of this ex vivo study was to compare the total glide path and canal preparation times of WaveOne Gold Glider (Dentsply Sirona) combined with the Primary WaveOne Gold (Dentsply Sirona), Edge GlidePath (Edge Endo, Albuquerque, New Mexico, USA) followed by the Primary EdgeOne Fire (EdgeEndo); and One File G Glide Path (Pac-Dent, Brea, CA, USA) file combined with the Primary One File G (Pac-Dent) Shaping file. Sixty curved untreated canals of extracted, human, mandibular molars were randomly divided into three groups of 20 canals each for mechanical glide path enlargement and root canal shaping. Group 1 (WaveOne Gold Glider + Primary WaveOne Gold); Group 2 (Edge GlidePath + Primary EdgeOne Fire); and Group 3 (One File G Reciprocating Glide Path File + Primary One File G Reciprocating shaping file). The total time taken to prepare a glide path and to complete the root canal preparation of each canal was recorded (in seconds) by means of an iPhone stopwatch (Apple Inc., Cupertino, California). The time taken to change files was not recorded. Throughout the instrumentation process, RC Prep was used as a lubricant, and5 mL 3% sodium hypochlorite was used as irrigation solution. Mean and standard deviations were determined for each group, and analysis of variance was used to statistically compare the mean glide path preparation times for the three groups. The fastest final canal preparation time was achieved by WOGG/PWOG (41.78 ± 10.58 s), followed by OFGP/ POFS (42.02 ± 12.16 s) and then EGP/PEOF (42.49 ± 10.44 s). There were no statistically significant differences between the canal preparation times of the three combination groups (p>0.05).

Full textAbstract:
The objective of this study was to evaluate the biofilm removal efficacy of three root canal treatment systems: ProUltra® PiezoFlow™, traditional needle irrigation, and the GentleWave® system in an ex-vivo benchtop study. Twenty-four extracted maxillary and mandibular molars were selected. Teeth were all instrumented to a master apical file size #25 with 4% taper. Teeth were then randomly divided into four experimental groups and two control groups. The root canals were inoculated with a culture of Enterococcus faecalis and incubated for five weeks to form a biofilm. Each group was then treated with one of the different root canal treatment systems using 6% sodium hypochlorite (NaOCl) as per the respective manufacturer’s recommendation followed by a rinse with water. Following treatment, teeth were decoronated and roots were sectioned longitudinally. Three scanning electron microscope images were taken at the apical level per root half at 5000x magnification. Images were scored by four calibrated examiners blind to group membership using a four-point scoring system (<5% coverage, 5-33%, 34-66%, and >66%). Results were analyzed using mixed model ANOVA. All the experimental groups were significantly better than the positive control group in removing biofilm. Among the experimental groups, the GentleWave® 15/04 group was significantly better than the other groups. There was no significant difference between the GentleWave® and the ProUltra® PiezoFlow™. Traditional needle irrigation scored the worst in reducing E. faecalis biofilm. The GentleWave™ system was as effective at intracanal biofilm removal as the ProUltra® PiezoFlow™ and better than traditional needle irrigation using 6% NaOCl as an irrigant.

O objetivo desse estudo in vitro foi comparar os efeitos de diferentes protocolos de irrigação final, envolvendo três soluções irrigadoras, submetidas ou não à ativação ultrassônica passiva (AUP), para a remoção de detritos e lama dentinária, após o preparo químico-mecânico do canal radicular de dentes bovinos. Os canais de 84 incisivos laterais bovinos foram classificados em 3 diferentes calibres e preparados com limas manuais acopladas a um contra-ângulo oscilatório (NSK, Tokio, Japão). As soluções irrigadoras testadas foram o NaOCL 2,5%, a CHX 2% e o soro fisiológico. Os dentes foram clivados e, no terço apical de uma das metades radiculares, foi confeccionado um sulco longitudinal, simulando extensões de canais ovais, posteriormente preenchidos com detritos artificiais. Essas metades, após justapostas, foram incluídas, individualmente, em muflas. Após randomização em seis grupos (n = 14) foram submetidas a diferentes protocolos de irrigação final. Nos grupos NaOCl/AUP, CHX/AUP e SORO/AUP a solução foi ativada ultrassonicamente 3 vezes por 20 segundos. Nos demais grupos, a AUP não foi utilizada. Em todos os grupos foi realizada uma irrigação com 5ml de EDTA 17% durante três minutos, seguida de 2ml da respectiva solução irigadora. Foram estabelecidos escores para a remoção de detritos e lama dentinária e a avaliação foi realizada por microscopia eletrônica de varredura. Foi demonstrada associação entre os escores de remoção de detritos e os protocolos que utilizaram AUP (P < 0,05). Não foi observada associação entre os escores de remoção de lama dentinária e os protocolos que utilizaram ou não AUP (P = 0,766), entretanto, houve associação entre os escores de remoção de lama dentinária e as soluções irrigadoras (P < 0,05). Os protocolos de irrigação final que utilizaram AUP foram mais efetivos na remoção de detritos do terço apical do que os que não utilizaram. Os protocolos de irrigação final que utilizaram NaOCl 2,5% e EDTA foram mais efetivos na remoção de lama dentinária do terço apical do que os que utilizaram CHX 2% e SORO, independentemente da utilização da AUP. Os diferentes calibres de dilatação não influenciaram na remoção de detritos e lama dentinária do terço apical.The aim of this in vitro study was to compare the effects of different final irrigation protocols, involving three irrigants, assossiated or not to passive ultrasonic irrigation (PUI). Debris and smear layer removal were evaluated after chemo-mechanical preparation of the bovine root canals. Eighty-four bovine lateral incisors were classified into three initial apical diameters and prepared with hand files attached to an oscillating handpiece (NSK, Tokio, Japan). The irrigants tested were 2.5% NaOCl, 2% CHX and saline. The teeth were split longitudinaly and in the apical third of one canal wall, a standardized groove was performed in order to simulate extensions of oval canals. Following this, these grooves were filled with dentin debris. After reassembling, the halves were included in a muffle. They were randomly divided into six groups (n = 14) and underwent to different final irrigation protocols. In groups NaOCl/PUI, CHX/PUI and SALINE/PUI the solution was ultrasonically activated 3 times for 20 seconds. In the other groups, PUI was not used. Irrigation with 5 ml 17% EDTA for three minutes followed by 2ml of the respective irrigant was performed in all groups. Specimens were scored for debris and smear layer removal and analyzed under scanning electron microscope. There was an association between the score of debris removal and protocols that used PUI (P < 0.05). No association was observed between the score of smear layer removal and the protocols that used PUI or not (P = 0.766); however, there was an association between the score of smear layer removal and the irrigants (P < 0.05). The final irrigation protocols that used PUI were more effective in removing debris from the apical third of those who did not. The final irrigation protocols that used 2,5% NaOCl and EDTA were more effective in removing smear layer at the apical third than the protocols that used 2% CHX and saline, regardless of the use PUI. Different apical diameters did not influence the debris and smear layer removal at the apical third.

Indiana University School of Dentistry located on the campus of Indiana University-Purdue University Indianapolis (IUPUI)This in-vitro, prospective, randomized study microscopically compared the debridement efficacy of negative pressure irrigation with the EndoVac (Discus Dental, Culver City, CA) versus the Canal CleanMax (Maximum Dental, Inc., Secaucus, NJ). Sixty extracted human canines were instrumented using a combination of hand-instrumentation with Lexicon K-type files and rotary instrumentation with ProTaper files. All canals were irrigated with 6.0-percent sodium hypochlorite and 17- percent ethylenediaminetetraacetic acid (EDTA). However, the irrigation/aspiration techniques differed among three groups of 20 randomly selected teeth. Group one (control) was irrigated with only a 12-ml Monoject syringe via 30-gauge side-vented, closed-end needle. Group two was irrigated with the EndoVac system. Group three was irrigated similar to group one, but with the adjunct of the Canal CleanMax system. All teeth were sectioned longitudinally, and the more intact sections were divided into coronal, middle, and apical thirds. Each portion of the canal was photographed with a scanning electron microscope (SEM). The photographs were scored by two independent examiners according to relative amount of debris and/or smear layer present, as well as relative number of patent dentinal tubules. These scores were statistically analyzed using a Krustal-Wallis test and Wilcoxon Rank Sum tests to determine differences between groups. The coronal aspect of root canal walls irrigated with the EndoVac system exhibited significantly less debris and/or smear layer present when compared to the coronal aspect of root canals irrigated with only a standard 12-ml Monoject syringe equipped with 30-gauge ProRinse side-vented, closed-end needle (control). There were no other significant differences in scores between any groups at any location. For all locations combined, the EndoVac system produced significantly cleaner root canal walls as compared to the control. No significant differences were seen between the Canal CleanMax and Control or Canal CleanMax and EndoVac. This study suggested negative pressure irrigation delivery with the EndoVac system during and after hand-rotary instrumentation is more effective in removal of debris and smear layer from the coronal third and combined thirds of root canal walls compared to irrigation with a standard 12-ml Monoject syringe equipped with 30-gauge ProRinse side-vented, closed-end needle.

Full textAbstract:
Indiana University-Purdue University Indianapolis (IUPUI)Introduction: One of the main objectives of endodontic therapy is to reduce microbes and remove inflamed pulpal tissue within the root canal system (RCS). This is accomplished through chemomechanical debridement of the RCS using hand and rotary instrumentation along with an antimicrobial irrigant. Today, the most commonly used irrigant is sodium hypochlorite (NaOCl), often at concentrations toxic to human cells. The use of ozone as an endodontic irrigant is a novel technique that has been proven to be antimicrobial against several microorganisms. However, independent research is lacking on ozone’s efficacy against an established endodontic biofilm. If ozone’s efficacy against biofilms is confirmed, the use of toxic and potentially dangerous sodium hypochlorite could be replaced in some clinical situations (i.e., regeneration, immature teeth, resorption) with a safer and effective alternative. Objective: The aim of the current study was to evaluate the anti-biofilm activity of different concentrations of ozonated water compared to various concentrations of NaOCl against an established endodontic biofilm of Enterococcus faecalis in root canal treated teeth in vitro. Materials and Methods: The crowns of similarly sized, maxillary anterior teeth were removed, and the roots cut to a standard length (12 mm). All root canals were instrumented to a standard size. Specimens were sterilized and then inoculated with E. faecalis, which were allowed to grow for two weeks to form an established biofilm. There were six treatment groups: 1) 6% NaOCl; 2) 1.5% NaOCl; 3) 16µg/mL ozonated water; 4) 25µg/mL ozonated water; 5) 50µg/mL ozonated water, and 6) saline. Following treatment, samples were collected, plated, and incubated for two days. The number of CFU/mL were determined, and samples visualized using confocal imaging. The effect of treatment group on bacterial counts was made using one-way ANOVA followed by pair-wise comparisons. Null Hypothesis: Endodontically treated teeth irrigated with ozonated water will not demonstrate a statistically significant decrease in the E. faecalis biofilm compared to those treated with sodium hypochlorite Results: CFUs were converted to log10 and compared using Fisher’s Exact tests or one-way ANOVA followed by pair-wise tests. In all observations utilizing NaOCl irrigation, no colonies formed following treatment. The two NaOCl groups, with 0 CFU/mL, were significantly different than the other four groups (p=0.009). Saline showed a trend towards higher CFU/mL than 50 µg/ml O3 (p=0.068). None of the other comparisons approached statistical significance (p=0.453 25 µg/ml O3, p=0.606 16 µg/ml O3, p=0.999 25 µg/ml O3 vs 50 µg/ml O3, p=0.990 16 µg/ml O3 vs 50 µg/ml O3, p=1.000 16 µg/ml O3 vs 25 µg/ml O3). Confocal imaging helped illustrate effects of irrigation and confirm CFU findings. Conclusion: The results of this study failed to reject the null hypothesis. There was a statistically significant difference in the E. faecalis biofilm remaining in the groups treated with ozonated water compared to those treated with NaOCl. However, there was a trend towards higher CFU/mL in the saline group compared to the 50µg/mL ozonated water group. According to this finding, future studies should evaluate the effects of higher concentrations of ozonated water against an established E. faecalis biofilm. In addition, other follow-up studies might include ozonated water’s effect on human cells, such as the stem cells of the apical papilla that are so critical to the success of regenerative endodontic procedures. Due to university and laboratory closures caused by the COVID-19 pandemic, this project was stopped short and an insufficient sample size did not allow for proper statistical power. Additional occasions should be run upon the university’s re-opening to allow for proper statistical power.

The use of sodium hypochlorite (NaOCI) as an endodontic irrigation solution is effective in eliminating microorganisms from the root canals of human teeth. The purpose of this in vitro study was to evaluate the antimicrobial effectiveness of electro-chemically activated water (ECA) as an endodontic irrigation solution. ECA is a solution comprising many different ions, molecules and radicals. Sixty caries-free, single root, adult, maxillary, anterior human teeth were used. The root canals were instrumented and irrigated with NaGCI in a similar method to that employed for in vivo root canal treatment. The external root surface of each tooth was sealed and the access cavity kept patent so that root canals could be inoculated with a suspension containing four bacterial. The teeth were randomly divided into four groups (n=15). Each group was irrigated ultrasonically, using solutions of distilled water (control), NaOCI (3.5%), and ECA, the latter at pH's 7.0 and 9.0 respectively. Antimicrobial effectiveness was established directly after irrigation and again seven days later, by counting colony forming units on blood agar plates and by spectrophotometric analysis. The surfaces of the root canals were visually examined by means of scanning electron microscopy. Large numbers of bacteria were present in the canals of teeth irrigated with distilled water. No bacteria were observed following irrigation with NaGCI. Neither of the ECA solutions were found to be effective against all the bacteria. Although some reduction in the number of bacteria was evident in the ECA groups, this was not statistically significant (p>0.05). Within the confines of this study ECA did not demonstrate antimicrobial effectiveness.Dissertation (MChD (Prosthodontics))--University of Pretoria, 2007.

A importância da limpeza mecânica e química do sistema de canais radiculares
durante o tratamento endodôntico tem sido repetidamente enfatizado. Já está comprovado que
a irrigação é a fase mais importante do tratamento em si, indiscutivelmente.
Pode-se ter sistemas avançados para instrumentação ou ótimas técnicas de obturação,
entretanto, a irrigação pode alcançar lugares no canal radicular onde a lima, seja manual ou
rotatória, não consegue penetrar e consegue remover a smear layer e detritos inorgânicos.
Em vários materias encontrados, como clorexidina, EDTA, ácido cítrico, ácido
peracético, peróxidos de uréia ou hidrogênio, detergentes, soro fisiológico, ainda o
hipoclorito, é o material de primeira escolha e o mais eficaz que os estudos e a atividade
clínica comprovam.
Sua eficácia depende da concentração empregada para cada caso em questão, seu
armazenamento correto e quantidade utilizada. Ele pode ser associado com outra substância
para que assim, possamos obter um resultado ainda mais satisfatório.The importance of mechanical and chemical cleaning of the root canal system during endodontic treatment has been repeatedly emphasized. It is already proven that irrigation is the most important phase of the treatment itself, indisputably. However, irrigation can reach places in the root canal where the file, whether manual or rotational, can not penetrate and can remove the smear layer and inorganic debris. In various materials, such as chlorhexidine, EDTA, citric acid, peracetic acid, urea or hydrogen peroxides, detergents, saline, still hypochlorite, is the first choice and most effective material that studies and clinical activity prove. Its effectiveness depends on the concentration used for each case in question, its correct storage and quantity used. It can be associated with another substance so that we can achieve an even more satisfactory result.

Full textAbstract:
Deciduous tooth is of great significance as it maintains the space for permanent dentition. Conventional pulpectomy procedure is performed with stainless steel hand files. The rigid nature of these files may cause bizarre canal shapes. The time taken during biomechanical preparation may lead to further worsening of the patient's cooperation, especially in Pediatric Endodontics. Though rotary file system has several advantages, it fails to clean the curved and oval shaped canals efficiently. The Self-Adjusting File (SAF) introduces a new era in Pediatric Endodontics by performing the conventional steps of shaping and cleaning at the same time. The SAF is a cylindrical hollow file that adjusts to the root canal in three dimensions and is a solitary file system formed of Ni-Ti matrix. The SAF is under continual irrigation through an irrigation device and works in an in-and-out vibration propelled by a handpiece. The SAF system has retained the original contour of the canals without dentinal cracks in primary teeth. The aim of this review is to describe design of the SAF, operational parameters and features, and advantages of SAF over other file systems in Pediatric Endodontics.

Full textAbstract:
Endodontics remains a rapidly advancing branch of restorative dentistry. It is highly likely that, by the time this book is published, several new or updated endodontic file systems will have been released. Despite the fairly rapid technological advances that the profession has seen, the key principles of endodontic treatment remain the same: 1. Eliminate microorganisms from the root canal system 2. Prevent reinfection of the root canal system 3. Retain a functional natural tooth. Whilst these principles are easy to discuss, they are consistently difficult to perform, due, in large part, to the complexity of the root canal system. Multiple theories, principles, and approaches have been discussed to help achieve an optimal technical and clinical outcome. However, evidence to favour one specific stage or system over another is lacking, and as such, a large degree of operator preference and experience will ultimately influence the treatment planning and technical strategy. Much like baking a cake, endodontic treatment relies upon a series of procedural steps to achieve a desirable outcome, which, for the patient, often equates to a functional, pain-free natural tooth. Good- quality magnification remains a key component of an endodontist’s armamentarium, and dental loupes or a dental operating microscope could not be recommended more highly. Key topics include: ● Endodontic case assessment, including root canal anatomy ● Pain management, including local anaesthesia ● Access and canal identification ● Vital pulp therapy, including caries management ● Canal negotiation and instrumentation ● Root canal irrigation ● Root canal obturation ● Restoration of the endodontically treated tooth.

Full textAbstract:
Endodontics is the study of the prevention and management of problems affecting the dentine, pulp, and periapical tissues. This chapter is a concise guide to the rationale behind root canal treatment, the instruments and materials available, and the modern techniques used. The chapter considers the anatomy of the root canal system including the average working lengths of pulp canals, the prevalence of lateral and accessory canals, and the location of the apical foramina. Alongside discussion of the indications and contraindications for root canal treatment, the aims and objectives of canal shaping, cleaning, and obturation are outlined. Detailed, step-by-step guidance is given for the root canal treatment procedure and common errors in canal preparation are highlighted. Management options are presented for some endodontic problems such as an acute periapical abscess and long-term possibilities for a definitive restoration are offered.
