Radiographic assessment of gender-related condylar head morphologic changes using a Cone Beam Computed Tomography. A retrospective study

Abstract

Objective: stratification of mandibular condylar head morphologic and dimensional variation in both genders. Materials and methods:This is a retrospective study included 800 subject. Sample assignment into two groups with block randomization for gender and age using a computer software. The CBCT of the participants were interpreted for classification of the condylar head shape and condylar head dimensions in terms of height, antro-posterior length and mediolateral width. Results:In regards to the condylar shape, there was no statistically significant difference between males and females at P-value >0.05. The condylar head height and width were found to be statistically significant between males and females at P-value <0.001. The highest mean value was found in males. Eventually, there was no statistically significant difference in anteroposterior parameter between males and females groups (p>0.05) on both sides. Conclusions:Within the limitation of the present study sample, the radiographic analysis has shown that there is no difference in condylar head morphology between males and females. In regards to dimensional variation the condylar head was found to be significantly wider and higher in males.

The effect of gender and site on the condylar head measurements in Diyala

“…Our results show condylar head width in right and left side, males have documented higher mean value than females, this agrees with results of El-Bahnasy, [18] they specified that males had mean mandibular condyle mediolateral width dimensions of 22.17 mm and 22.22 mm on the sides (right and left), respectively; females had mean condylar width measurements of 16.74 mm and 17.03 mm on the sides (right and left), respectively with a statistically significant change.…”

“…Our results show condylar head length and condylar head height in sides (right and left), males have documented high mean value than females, these results approve with the results of El-Bahnasy, [18] they detailed that no statistically significant variance in the anteroposterior length of the head of condyle between males and females. Males had a mean condylar length of 9.20 mm and 9.08 mm on the sides (right and left), respectively more than females which had a mean condylar length of 7.35 mm and 7.24 mm on the sides (right and left), respectively.…”

“…It is essential to report and exactly describe all variations. This could aid with the finding of several pathological conditions that affect TMJ [18].…”
