Aim: Endodontic surgery is a treatment for persistent peri-radicular pathological conditions that do not improve after endodontic treatment. The aim of this study was to evaluate the quality of endodontic treatment, technical error types seen in root canals and the periapical condition of the teeth in patients undergoing periapical surgery, and thus to analyze the reasons leading to periapical surgery. Methodology: Clinical and radiographic data of 301 periapical surgery cases were retrospectively evaluated in this study. The causes of periapical surgery were classified into technical and biological reasons. Results: In this study, 51.8 % of periapical surgery cases were related to biological factors and 48.2 % were related to technical factors. Maxillary anterior teeth were the most common teeth undergoing apical surgery with a rate of 66,8 %.  The most common technical reasons were non-homogeneous filling (15,6 %), underfilling (12,0 %) and overfilling (9,6 %). The most common biological reasons were cysts (30,2 %), traumas (16,6 %) and apical abscess (5,0 %).  37.5% of cases undergoing periapical surgery, the diameter of the cystic lesion was 10mm or more. Conclusion: The number of cases of apical periodontitis is increasing in the community due to insufficiently filled root canals. Increasing the quality of root canal treatments applied by dentists will reduce the need for periapical surgery by reducing the incidence of apical periodontitis.   How to cite this article: Ekici Ö.

Objective: The aim of this study was evaluate radiographically prevalence of apical periodontitis (AP) in endodontically treated teeth (ETT) and relate with demographic factors, quality of endodontic treatment and coronal restoration. Material and methods: Data were collected from dental records wich contained full-mouth radiographic series. In ETT, arch, dental group and presence of AP were evaluated. Quality of root canal filling, presence and quality of coronal restoration and type of restorative material were also collected. Data were evaluated using descriptive statistics and Chi-square Test. Results: Of 70 patients included in the final sample, the majority were female (54.3%) and age ranged from 13 to 77 years (47.14 ± 13.18). Of 1,333 teeth evaluated, 73 (5.4%) had endodontic treatment, being the majority maxillary (74%) and anterior teeth (52.1%). Of teeth without endodontic treatment, 320 (25.4%) had AP. Failure rate was high (52.8%) and quality of root canal filling and coronal restoration were considered inadequate in majority cases (58.3% and 47.7%, respectively). Dental group had a statistically significant relationship with presence of AP in ETT, being more frequent in anterior teeth (p = 0.019). Conclusion: It was concluded that prevalence of AP in ETT was high and dental group was the factor that most influenced prevalence of AP in ETT.KeywordsApical periodontitis; Radiography; Root canal filling.

Object. Causes of failure of endodontic treatment and causes of tooth extraction with a diagnosis of chronic apical periodontitis. Purpose ― to analyze the causes of failure of endodontic treatment and the causes of tooth extraction with a diagnosis of chronic apical periodontitis to determine ways to improve the effectiveness of conservative treatment. Methodology. A retrospective analysis of 864 medical records of a dental patient and 532 results of x-ray examinations of patients who underwent tooth extraction was carried out. 198 dentists-therapists of the city of Tyumen and the South of the Tyumen region were interviewed to determine the shortcomings of endodontic treatment. During the survey, doctors expressed their subjective opinion about the main reasons for the failure of therapeutic treatment of teeth with apical periodontitis and the reasons for their subsequent tooth extraction. Results. According to the survey, the failure of conservative treatment is most often associated with non-compliance with treatment protocols and the complexity of the anatomical structure of the root canals, as well as the inability to adequately clean the root canal system. A retrospective analysis of the data related to tooth extraction revealed that the main cause of tooth extraction is chronic apical periodontitis, which accounts for 69 %. The main reason for the removal of teeth diagnosed with chronic apical periodontitis was a significant destruction of the crown. Summary. In the course of this work, we justified the need to improve existing methods of conservative treatment of apical periodontitis. Improvement of endodontic treatment should be aimed at the development and implementation of effective methods of root canal cleaning and irrigation solution activation. In order to improve the prognosis of endodontic treatment and reduce the proportion of tooth extractions for periodontitis, it is necessary to improve the quality of the final restoration and to monitor its tightness.

The aim of this study was to assess the prevalence and risk factors of apical periodontitis in endodontically treated teeth in a selected population of Brazilian adults. A total of 1,372 periapical radiographs of endodontically treated teeth were analyzed based on the quality of root filling, status of coronal restoration and presence of posts associated with apical periodontitis (AP). Data were analyzed statistically using odds ratio, confidence intervals and chi-square test. The prevalence of AP with adequate endodontic treatment was low (16.5%). This percentage dropped to 12.1% in cases with adequate root filling and adequate coronal restoration. Teeth with adequate endodontic treatment and poor coronal restoration had an AP prevalence of 27.9%. AP increased to 71.7% in teeth with poor endodontic treatment associated with poor coronal restoration. When poor endodontic treatment was combined with adequate coronal restoration, AP prevalence was 61.8%. The prevalence of AP was low when associated with high technical quality of root canal treatment. Poor coronal restoration increased the risk of AP even when endodontic treatment was adequate (OR=2.80; 95%CI=1.87-4.22). The presence of intracanal posts had no influence on AP prevalence.

The objective of this clinical study was to evaluate by polymerase chain reaction (PCR) the antimicrobial efficacy and the outcome of an endodontic protocol treatment (EPT) performed by under-graduated dental students on infected root canals associated with periapical lesions. Fifty-six patients attending for treatment of pulp necrosis and apical periodontitis were included. A specific EPT approach was performed and DNA extracts were taken at the baseline (S1), after a disinfection-neutralization procedure (S2), post-chemomechanical preparation (S3) and after Intracanal medication (S4) for the presence of specific bacteria. The outcome of the EPT was assessed radiographically using the Periapical Index-system (PAI) after 18-month follow-up. An intergroup evaluation shows that when comparing S1 to S3, S1 to S4, S2 to S3, and S2 to S4, the presence of bacteria were significantly reduced (P < 0.05). Finally, S4 was not significantly reduced when compared with S3 (P > 0.05). The most prevalent species in their respect order were Actinomyces Israelii > Enterococcus Faecalis > Fusobacterium Nucleatum/Prevotella Nigrescens > Phorphyromonas Endodontalis. After the 18-month follow-up, the overall success rate of root canal – treated teeth was of 88% (PAI 1 or 2). This In Vivo study demonstrated that EPT significantly reduced the number of cases with positive results for the studied bacteria, showing a profound positive impact in the outcome of endodontic treatment of teeth diagnosed with Pulp Necrosis and Apical Periodontitis.

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.   How to cite this article: Dinger E, Bodrumlu E.

Mandibular Canine

Successful endodontic treatment depends upon the clinician’s precise knowledge and ability to manage complex internal anatomy in order to avoid failure during endodontic treatment. Mandibular canines normally have single root with centrally placed single canal and internal anatomy as simple as could be expected, but there are such canines with a single root with two canals, two roots or fused roots. The occurrence of two canal joining to one for a men may be a rare entity with 4-15% prevalence. Canine is the cornerstone of mouth due to its position and very important as abutment for any type of restoration, so long term success of the restorative depend directly on the quality of endodontic treatment. This article presents a case series of successful endodontic management of mandibular canine with two canals which merge into one canal with one foramina and mandibular canine with two roots and two canals.

The goal of endodontic treatment is to remove all the vital and necrotic tissues, microorganisms and microbial byproducts from root canal system. This goal can be achieved through chemical and mechanical debridement of root canals. This article narrates the specifics and requirements of the irrigation solutions. Sodium hypochlorite is proposed as the primary irrigant by virtue of its organic tissue dissolution capacity and broad antimicrobial properties. On the other hand, chelation solutions are recommended as auxiliary solutions to remove the smear layer or to hinder its formation on dentin surface. Thus, it's hoped that sealers and root canal fillers can penetrate to dentin tubules and obturate the canals hermetically. There are new studies on traditional irrigants especially on some irrigants that can replace sodium hypoclorite. This article reviews the new irrigants which can be used in future endodontic practice, and their advantages and limitations. Moreover, actions and interactions of recently used irrigants are adverted.   How to cite this article: Topbas C, Adiguzel O. Endodontic Irrigation Solutions: A Review.

The aim of the present study was to assess the quality of canal obturation performed by undergraduate denal students at Saveetha Dental College and Hospitals, Chennai. Records of 200 endodontically treated teeth from patients who were visited by undergraduate students between month of November 2014 to May 2015. Periapical radiographs of all treated teeth were assessed in terms of canal obturation quality (adequate density and length). Forty-five percent of teeth fulfilled the criteria of an acceptable root canal obturation. Adequate length and density of root filling was found in 89% and 34% of teeth, respectively. There was a significant difference between maxillary and mandibular teeth regarding the length of root canal obturation. A significant difference was observed between molars and other tooth types. The frequency of root canals with an acceptable filling was significantly greater in the anterior teeth compared to premolars or molars. The technical quality of root canal treatment performed by undergraduate dental students was found to be less than ideal.

ABSTRACTObjectives: The purpose of this study was to evaluate the radiographic quality of root canal fillings performed by first and second clinical year dental students at the Faculty of Dentistry in Süleyman Demirel University, Turkey. Methods: The technical quality of 833 root canal fillings was evaluated by three examiners according to the density of the filling and the distance between the end of the filling and the radiographic apex. A root canal with acceptable filling length and homogeneous root filling was defined as being good quality endodontic work (GQEW). A treated tooth was defined as having good quality endodontic work tooth (GQEW-T) when all its canals had a GQEW rating. Results: A Chi-square (χ2) test at the 0.05 significance level was used for the statistical analysis of the data. Of a total of 833 root canals, 662 (79.47%) root fillings were classed as GQEW. Two hundred fifty canals (73.4%) (135 teeth) treated by first clinical year dental students were defined as GQEW-T while 412 canals (204 teeth) (73.9%) treated by second clinical year dental students were defined as GQEW-T (P>.05). Most of the GQEW-T were defined in anterior teeth (90.1%), whereas the fewest were in molar teeth (46.6%) for both first and second clinical year dental students (P<.001). Conclusions: The quality of root canal fillings in anterior teeth performed by undergraduate dental students in Isparta, Turkey was satisfactory. However, to improve the success with molar teeth, education about newer techniques and instruments must be incorporated into the preclinical and clinical curriculum. (Eur J Dent 2011;5:324-330)
