Cone Beam Computed Tomography Evaluation of the Morphological Variation and Width in Mandibular Condyle

Classify the normal morphology of mandibular condyle to facilitate the diagnosis of any pathology or abnormal conditions associated with it using cone beam computed tomography (CBCT).

A total of 100 joints of 50 subjects with age range of 20 to 50 years were examined prospectively using CBCT images. The mandibular condylar morphology was classified into convex, round, flat, and angled the widest area of the condylar head measured to evaluate the size variation in different age groups for both genders and side.

Round shape condyle is more frequent than other varieties and angled shape was the less frequent shape. There was no significant difference between gender and condyle shape but the round and angled shape were more obvious in females than males. Convex type was more prevalent to shown bilateral symmetrical shape than other varieties, the condylar head mean of width measuring was 14.85 mm in age group 20 to 29 comparable to 14.45 mm and 14.42 mm in age groups 30 to 39 and 40 to 50 years, respectively.

CBCT facilitates the precise examination of TMJ in 3 planes that play a great role in an accurate visualization of the condyle to provide early diagnosis for any disorder in the region.
