Abstract

Objectives: The aim of the study is to determine classifications of root canals of mandibular first molars according to Vertucci 1984 in Vietnamese on ConeBeam CT. Methods: The study was conducted on 332 mandibular first molars of 166 patients who had exposured using CBCT indicated by dentists in Nguyen Trai Dental CT Central, HoChiMinh City, from October 2015 to June 2016. CBCT digital images were displayed on the 14 inches flat monitor, at 1366 x 768 pixel resolution with EzImplant CD viewer software. The positions of mandibular first molars (36 and 46) were recorded. The orifices, middle thirds, apical thirds of the canals of mandibular first molars were observed and the root canals of each root of mandibular first molars were observed in three planes. Classifications of root canals of mandibular first molars were recorded. Results: For the mesial roots of mandibular first molars, classification of Vertucci type IV was most popular at rate of 60.8% - 68.3%, following by classification of Vertucci type II at rate of 24.4% - 30.6%. For the distal roots of these teeth, classification of Vertucci type I was the most popular at rate of 80.8% - 97.6%. When mandibular first molars had three roots, 100% distolingual roots were classification of Vertucci type I. Conclusions: Classification of Vertucci type IV was most popular in mesial roots of mandibular first molars. Classification of Vertucci type I was most popular in distal/ distobuccal roots of these teeth. When mandibular first molars had three roots, 100% distolingual roots were type I Vertucci.
