Remodeling of the antegonial angle region in the human mandible: a panoramic radiographic cross-sectional study.
OBJECTIVE
This study analyzed changes in the antegonial region in relation to age, gender, and dental status.


METHODS
A total of one thousand patients (five hundred males and five hundred females), who were prescribed panoramic radiograph for various purposes were included in the study. The patients were categorized according to age, gender and dentition status. Panoramic radiographs were traced and antegonial angles and depths were measured.


RESULTS
A trend of decrease in the antegonial angle and increase in antegonial depth with age was observed in both males and females. Furthermore there were differences between right and left side antegonial angle and depth, with left side angle more than right and right side depth more than left. There was a significant decrease in the values of antegonial angle and significant increase in the values of antegonial depth as the dentition status changed from completely dentulous to partially dentulous and from partially dentulous to completely edentulous state.


CONCLUSIONS
The antegonial angle decreases with the advancing age and thereby increases the antegonial depth. Similar trends are seen when teeth are lost. Furthermore there is an inherent asymmetry in the antegonial region in right and left side.
