Türkiye’nin do?u b?lgesi nüfusundaki mandibular molar di?lerin k?k ve kanal yap?lar?n?n konik ???nl? bilgisayarl? tomografi ile de?erlendirilmesi

摘要

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 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 canal configuration rate of 72.4%, whereas distal roots showed type?1 canal configuration rate of 69.3%. The Mesial root of the first molar teeth with three canals showed type?2 canal configuration (62.5%), the distal roots showed completely type?1 canal configuration (100%). The rate of 36% for type?4 canal configuration was detected in mesial roots and the rate of 95.8% for type?1 canal configuration was detected in distal roots of second molars with two canals. Type?1 canal 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 frequent. Type?1 canal configuration was most prevalent in the distal roots, whereas the mesial roots had more complex root canal morphology and showed mostly type?4 canal configuration
