Background: The gonial region of mandible plays a significant role in the determination of mandibular basal bone morphology. Gonial Angle is important for maintenance of a harmonius facial profile whereas Gonial Index is an indicator of the bone quality of the mandibular gonial region.

Objectives: To examine the influence of age on two quantitative radiomorphometric indices of mandible, Gonial Angle (GA) and Gonial Index (GI) in a group of North-Indian population.

Material and Methods: 60 adult human orthopantomographs were evaluated and divided into six age groups (35-65 years) with equal number of cases. Gonial Angle and Gonial Index were measured bilaterally on each radiograph. The measurements were analyzed for interactions with age and other interrelationships between the indices. The data obtained was subjected to statistical analysis using SPSS (Statistical Package for Social Studies) software version No. 18 and Mann- Whitney tests were used for various comparisons.

Results: Gonial angle showed a significant positive correlation with age as the mean gonial angle values showed an increase with increasing age. Whereas in sharp contrast to this, gonial index showed no correlation with age as the mean gonial index values showed no pattern of either increase or decrease with increase in age. The correlation between gonial angle and gonial index was statistically insignificant (p>0.05).

Conclusion: Age had a significant influence on the angular radiomorphometric index i.e. gonial angle but the linear radiomorphometric index i.e. gonial index remained independent of age.
