Abstract

Introduction

The aim of the present study was to evaluate the presence of the median perforating canal (MPC) and its morphometric measurements in Cone Beam CT (CBCT) scans of adult patients, correlating the findings with sex, age and skeletal facial patterns.

Material and methods

717 CBCT scans were selected from a Brazilian population and the presence of the MPC was recorded. MPC diameter was measured in three points: lingual, medial and buccal. To determine the correlation between MPC presence and sex, age and ANB angle classifications the Chi-square test was performed. MPC diameters were related to sex, age and skeletal discrepancies using Mann-Whitney U and Kruskal-Wallis tests. The level of significance adopted was 5%.

Results

Of the 717 CBCT scans analyzed, the MPC was present in 181 patients (25.24%), 279 (38.91%) men and 438 (61.09%) women. The mean age was 37.91 (±14.46) years old, ranging from 18 to 88 years old. There were no differences in the presence of MPC between women and men (p = 0.85), between skeletal discrepancies (p = 0.09) and age groups (p = 0.94). Regarding the MPC diameter, statistical difference was found only for the medial diameter between sexes (p = 0.04), with the highest values in men.
