Purpose: The purpose of this study is to investigate the root numbers, channel numbers and frequency distribution of root channel morphologies of the lower anterior teeth using conic radiated computer tomography (KIBT). In the study, 60 KIBT images taken due to different clinical indications, including 26 women and 34 men, were evaluated as retrospective. A total of 237 teeth were studied in terms of gender and symmetry. Two times in a period of three weeks, a single observer performed the frequency distribution of the root channel morphologies classified according to the root number, the number of channels and the Vertucci method. The statistical analysis was done with the SPSS 16.0 version software program. Results: A single root was observed in all of the teeth evaluated in the study. On the right side, 64% of the understations in women, 76.9% of the understations; 75.8% of the understations in men and 73.5% of the understations had one channel. On the left side, 65.4 percent of the lower power plants in women, 69.2 percent of the lower laterals; 73.5 percent of the lower power plants in men and 81.8 percent of the lower laterals had a single channel. 76.1 percent of women and 81.1 percent of men had type 1 canal morphology in the lower anterior teeth. There is no statistically significant difference in gender and symmetry. The result: the root canal morphologies of the teeth to be treated against the possibility of variation should be well known. KIBT imaging is a very effective method to evaluate root channel morphology. Keywords Cut tooth, conic radiated computer tomography, root channel morphology, mandibula
