Objective: This study aimed to measure the buccolingual direction and mesiodistal direction diameters in the apical third of the root canal maxillary incisor teeth using cone-beam computed tomography scans and to examine the effect of age, gender, and previous trauma.

Methods: Totally 58 maxillary incisors were studied. We collected data regarding sex, age, and previous dental trauma. OnDemand 3-dimensional software (Cybermed, Seoul, Korea) was used to measure the canal's diameter in buccolingual and mesiodistal directions at 1, 3, and 5 mm from the apex. The results were statistically analyzed using the t-test for the comparison of the axial diameter at each level, and Pearson chi-square test was used for the comparison of age or gender and canal diameter. The significance level was set at P < .05.

Results: The buccolingual diameter was larger than the mesiodistal diameter in all measurements. A constant decrease in diameter was observed toward the apex. The most common type of apical part of the canal is oval and tapered.

Conclusions: Given the results, adjustments to the chemo-mechanical preparation and obturation method to the canal morphology must be made.
