Özet:

Objectives: The aim of this study was to examine the root canal morphology of mandibular molars using cone beam computed tomography images of individuals living in the East of Turkey.Materials and Methods: The tomographic images of a total of 183 patients attending the Oral and Maxillofacial Radiology Department and clinical records were taken between 2011-2013 years were evaluated and clinical records. Root and canal diversities were classified according to the methods created by Vertucci and Gulabivala et al.Results: 173 first molar and 235 second molar teeth were examined among evaluated 155 patients. While the majority of the molar teeth had two separate roots (94.2% of the first molars, second molars 81. 7%), three separate roots in first molars and second molars were found respectively 4.6% and 2.1%. Mesial roots of first molars with two separate roots showed type 4 channel configuration rate of 72.4%, whereas distal roots showed type 1 channel configuration rate of 69.3%. The Mesial root of the first molar teeth with three channels showed type 2 channel configuration (62.5%), the distal roots showed completely type 1 channel configuration (100%). The rate of 36% for type 4 channel configuration was detected in mesial roots and the rate of 95.8% for type 1 channel configuration was detected in distal roots of second molars with two channels. Type 1 channel configuration was most prevalent in the three rooted molars. Conclusions: While, two separate roots were most prevalent in each of two teeth groups, three separate roots were seen less frequently. Type 1 channel configuration was most prevalent in the distal roots, whereas the mesial roots had more complex root channel morphology and showed mostly type 4 channel configuration
