The success of an Endodontic treatment relies on the position and morphology of root canals. It is important for a clinician to be familiar with the canal morphology to negotiate and thereby filling the canals with an inert material. But, the possibility of negotiating the canals with the use of conventional technique alone is difficult. Hence, careful examination with the use of advanced techniques to enhance vision is required to minimize the rate of treatment failures. To compare the efficiency of three methods Cone-Beam computed Tomography (CBCT), clinical analysis, AND Dental Loupes in detecting the MB2 canal in maxillary first molars.One hundred and fifty extracted intact permanent molars were collected. Two examiners i.e., one Endodontist and a Radiologist examined CBCT images of teeth for the number and position of root canals. The first stage included unaided examination using an explorer and K- files. While those teeth that were failed to locate the canals were examined using dental loupes for better magnification. The results were analyzed by McNemar's tests with Bonferroni correction, and Chi-square test using SPSS software v21.Among 150 extracted teeth that were compared,MB2 was detected using CBCT in around 68% of the teeth, while with the use of naked eye and dental loupes, it was found to be around 30% and 66% respectively and the difference in the detection rates was statistically significant.With the view of the parameter under consideration, CBCT has high detection rates followed by dental loupes and naked eye vision. The efficiency of CBCT scans and dental loupes in detecting a second mesio-buccal canal, thus making it more likely to be treated by the clinician.

Abstract Objective: The aim of the study was to compare the canal transportation and centering ability of Rotary ProTaper Next, Hyflex CM and Wave One primary systems using cone beam computed tomography (CBCT) in curved root canals. Materials and Methods: Total 30 freshly extracted maxillary first molars having root canals with curvature between 10°- 20° were divided into three groups of 10 teeth each. All teeth were scanned by CBCT to determine the root canal shape before instrumentation. In Group 1, the canals were prepared with ProTaper Next files, in Group 2 with Hyflex CM files and in Group 3 with Wave One files. After preparation, post-instrumentation scan was performed. Pre-instrumentation and post-instrumentation images were obtained at 3 mm and 6 mm above the apical foramen and were compared using CBCT software. The amount of canal transportation and centering ability were assessed and statistically compared with one way analysis of variance and Tukey honestly significant test. (p<0.05). Results: All instrumentation systems used resulted in some amount of canal transportation. Data obtained suggested that Wave One files caused significantly lesser transportation and remained better centered in the canal than Hyflex CM and Rotary ProTaper Next files. Conclusion: The canal preparation with Wave One files results in lesser transportation and better centering ability than Hyflex CM and ProTaper Next rotary files in curved root canals.

ABSTRACT Introduction Endodontic treatment requires knowledge of root canal morphology and its commonly occurring variation. The utility and relevance of cone beam computed tomography (CBCT) to the practice of endodontics is reported with increasing frequency in the field of endodontics for successful procedures. Therefore, the present study is undertaken to assess the variation in number and morphology of the root canals of primary molars. Materials and methods Extracted primary molars with at least two-thirds of intact root, and 7 to 12 mm length were cleaned in water and stored in 0.5% sodium hypochlorite for 1 week. Thereafter, the anatomy of the root canals of these primary molars was assessed through CBCT. Results In the present study, the majority of canals were ribbon shaped. Accessory canals were few and maximum number was found to be present in mesiobuccal root of maxillary first molar and the least in mesiobuccal root of mandibular second molar. Conclusion The CBCT proved to be as accurate as the gold standard in studying the presence of accessory canals with clinical applicability. This study highlights the usefulness of CBCT imaging for accurate diagnosis of the unusual canal morphology. How to cite this article Joshi N, Deshpande A, Poonacha KS, Bargale S, Naik K, Mehta D.

ABSTRACT Aim To evaluate the remaining dentin thickness of teeth after cleaning and shaping the root canal using three rotary instrumentation technique using cone-beam computed tomography (CBCT). Materials and methods This in vitro study is being done with 30 premolar samples with 20’ curvature. The study is divided into three groups a CBCT was taken to measure the shortest distance from the root canal outline to the closest adjacent root surface was measured at each level from the cementoenamel junction (CEJ) (1,3, 5 and 7 mm) before and after root canal instrumentation. The purpose of this study was to compare the effects of different instruments used to prepare curved root canals on the remaining cervical dentin thickness and total amount of dentin removed from root canals during instrumentation by using multi-slice CBCT. The remaining dentin thickness is very much necessary for the success rate of root canal treatment. However, this study helps to prove that a conservative preparation with a sound remaining dentin thickness is much more advisable. Result It was observed that there was a significant difference at 1 and 3 mm (p < 0.05) and at 5 and 7 mm there was no significant difference (p > 0.05). Mtwo has removed less amount dentin when compared to ProTaper Universal and ProTaper Next system at 1 and 3 mm. Conclusion Under the conditions of the study, we concluded that ProTaper Universal and ProTaper Next should be used judiciously, as it causes higher thinning of root dentin of the root when compared with Mtwo.

The Relationship

Objective: The current study aimed to investigate the relationship between canal configuration, distance between mesiobuccal (MB) and mesiolingual (ML) orifices and the degree of canals curvature in the mesial root of permanent mandibular first molars in a sample of Sudanese population using cone-beam computed tomography (CBCT). Material and Methods: A total of 143 extracted mandibular first molars were processed and scanned with CBCT to determine the configuration of the mesial root canals according to the Vertucci classification. The interorificial distance and the degree of canal curvature in clinical (CV) and proximal (PV) views using Schneider technique were assessed. Results: The commonest canal configuration was type IV (53.1%). The interorificial distance was significantly shorter in type VI compared to other types (P < 0.05). Significant association was found for type IV between the MB and ML canal in the primary curvature regarding CV and PV, and for type II regarding PV in primary and secondary curvature (P < 0.05). In type IV the degree of secondary curvature of MB canal regarding PV, and in the ML canal in CV was significantly lower compared to other types (P < 0.05). Significant correlation was seen in PV of primary curvature in the MB for type VI (P < 0.05). Conclusion: The interorificial distance and secondary curvatures in CV for MB canal were found to be key factors for predicting root canal patterns in PV.KeywordsCanal morphology; Canal curvature; Interorificial distance; Mandibular molars.
