EX VIVO EVALUATION OF THE ROOT CANAL MORPHOLOGY OF MESIAL ROOT OF PERMANENT MANDIBULAR FIRST AND SECOND MOLARS USING CBCT
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2017, Vol 6, Issue 68
Abstract
BACKGROUND As it has been well proven in the literature that one of the predominant reasons for the failure of root canal treatment is the lack of thorough knowledge of the pulp anatomy and its frequent variations. It is very important for operators to visualise the internal anatomic relationships of teeth before undertaking endodontic therapy. Cone beam computed tomography (CBCT) technology, with its accurate and high-quality three-dimensional representations of anatomic structures offers tremendous improvements in diagnostic capabilities. The aim of this study was to evaluate the root canal configuration and minimum width of dentin at the danger zone area of mesial roots of first and second mandibular permanent molars using cone beam computed tomography in vitro. MATERIALS AND METHODS Fifty freshly extracted permanent mandibular first and fifty mandibular second molars were collected and scanned using cone beam computed tomography and analysed using Dicom software for this descriptive study. Descriptive statistics were used to find out the root canal configuration and minimum width of dentin at the danger zone area. One way, ANOVA and Post-hoc statistical tests were done. RESULTS The results revealed that Vertucci type IV configuration was most prevalent in mesial roots of mandibular first molars (56%-64%) as well as in mandibular second molars (52%-64%). Type II, III and VIII configurations were also found. The mean width of dentin at the distal (furcal) surface concavity for mesiobuccal canal of mandibular first and second molar was found to be 0.90-0.97 mm and 0.95-0.98 mm respectively and for mesiolingual canal, it was 1.03-1.08 mm and 0.93-0.94 mm respectively for mandibular first and second molars. CONCLUSION Vertucci Type IV configuration has been found to be the most prevalent in both mandibular first and second molars and the width of dentin at the danger zone area is between 0.90 mm and 1.03 mm.
