ABSTRACT Introduction The success of endodontic therapy depends upon the ability of the clinician to locate, clean, shape and completely obturate all the root canal systems present in a tooth. In the recent times number of additional canals vs traditional canals has been very striking and pointing toward a greater degree of variation in the root canal morphology which needs to studied, understood and born in mind during practice so as to enhance the success. Introduction of surgical operating microscope is a major breakthrough in enhancement of vision in endodontics which not only gives required magnification but also coaxial illumination and video output. These facilities should be of a great help in location of small otherwise difficult to locate accessory canals. Materials and methods This in vivo study was planned to study variations in the canal anatomy of maxillary and mandibular first molar using surgical operating microscope using 200 first molar teeth, 100 maxillary and 100 mandibular groups, each group to be divided into 50 males and 50 female subgroups. After access opening chambers were cleaned, dried and observed and imaged under the microscope. Results The observations were recorded and incidences of variations in anatomy were analyzed subjecting the same to SPSS version 16.0. Conclusion It was observed that surgical operating microscope enhances clinician's ability to locate additional canals in the teeth. How to cite this article Abrar BAS, Pawar MG.

Canal Morphology

Successful root canal therapy requires an in-depth knowledge of root canal morphology.False assumptions about the root canal anatomy of teeth may lead to misdiagnosis, missed canals, improper debridement and breakage of root canal instruments during root canal treatment. The objective of this paper was to review the various methods used to study and understand root canal systems. The complexity of root canal morphology presents a challenge to any clinician. Any attempt to perform root canal therapy must be preceded with a thorough understanding of the anatomy of both the pulp chamber and the root canal system.Several methods have been used to examine the root canal system ranging from in vitro methods such as sectioning of teeth, metal castings to advanced in vivo tomographic imaging, along with the use of magnificationBangladesh Journal of Dental Research and Education Vol.5(2) 2015: 59-63

Aim: The aim of this study was to investigate the incidence of the presence of accessory canals in the root canal of the maxillary first molar teeth affected by Molar Incisor Hypomineralization (MIH).Methodology: A total of 12 maxillary first molar teeth affected by MIH were obtained from 10 children aged from 10 to 12 years. The frequency of the presence of accessory canals was examined by using microcomputed tomography and 3D image software. Results: Accessory canals were observed in the mesiobuccal (MB) canal in all of the samples with a statistically significant difference.(p<0.05) It was observed that the accessory canals were mostly in communication with the canals in the MB root and that furcal accessory canals were found in 10 (83.33%) teeth. The incidence of accessory canals was 75% in the distobuccal (DB) canal and it was 66.66% in the palatal (P) canal.Conclusion: The incidence of the presence of accessory canals in DB and P canals and furcation is higher in the teeth affected by MIH.   How to cite this article: Özükoç C.

The purpose of this study was to determine the variations in the number of canals and its morphology in permanent mandibular first molars using cone-beam computed tomography (CBCT) in a subset of Indian population. A total of 350 CBCT scans were collected and evaluated in all three orthogonal planes to determine the number of root canals and study their anatomic variations using Vertucci’s classification.: The total number of roots and root canals, the root canal configuration, the incidence, and the correlations between left- and right-side occurrences and between males and females were analysed. Statistically significant differences were evaluated using the chi-square test with SPSS 16.0 for Windows (SPSS, Chicago, IL), with significance set at p &#60; 0.05.: The results of this study showed that predominantly, two thirds of the subjects had type VI mesial canal configuration and two-thirds had type I distal canal configuration. Also there was significant variance in the canal anatomy across gender and age of the subjects.: CBCT is a clinically useful tool in understanding the variations in root canal morphology, which guides in the assessment of the canal morphology aiding in successful root canal treatment.

Canal Morphology

Root canal treatment of tooth with aberrant root canal morphology is very challenging. So thorough knowledge of both the external and internal anatomy of teeth is an important aspect of root canal treatment. With the advancement in technology it is imperative to use modern diagnostic tools such as magnification devices, CBCT, microscopes, and RVG to confirm the presence of these aberrant configurations. However, in everyday endodontic practice, clinicians have to treat teeth with atypical configurations for root canal treatment to be successful. This case report presents the management of a mandibular first molar with six root canals, four in mesial and two in distal root, and also emphasizes the use and importance of Cone Beam Computed Tomography (CBCT) as a diagnostic tool in endodontics.
