摘要

Objective

The aim was to evaluate the location of the mandibular canal (MC) using CBCT images.

Study design

A total of 104 samples were selected for the study. The position and course of the MC from the 2nd molar region to the 2nd premolar were measured at three different positions, that is, distal to the 2nd premolar, 1st molar and 2nd molar. At each of the three cross sections six specific linear distances from the MC were measured, that is, total height, total width, superior and inferior height, buccal and lingual width. The results were subjected to statistical analysis using SPSS 23.0 software.

Results

The mean age of the subjects were 32.27 years. There was no statistical significance based on right and left side.The mean total height (Rt = 25. 51 ± 3.02 and Lt = 24.9 ± 2.53) and mean lingual width (Rt = 3.74 ± 1.76 and Lt = 3.67 ± 1.72) was more at P1 (just between the second premolar and first molar) comparatively. The mean buccal width was more (Rt = 5.66 ± 1.35 and Lt = 5.45 ± 1.42) at P3 (just distal to the second molar).

Conclusion

The linear distances from the MC, such as superior height, were greater than inferior height and buccal distance was greater than lingual distance on both left and right sides. The buccolingual course of the MC has been assumed to be advantageous for implant placement.
