Background: The radiographic method for deter­mining the estimated age has the advantage of being non-invasive and the orthopantomogram images are digitally processed. Canines have a strong corre­la­tion with chronological age and have good resistance and large pulp space. This study aimed to determine the difference in age estimates using the Kvaal method on the right and left mandibular canines.

Subjects and Method: There were 80 ortho­pantomogram samples from dental and oral clinic patients who had undergone orthopantomography at the Radiology Installation of Dr. Moewardi Hos­pital, from January 2019 to December 2020. The estimated age of right and left canines was calcu­lated based on the Kvaal method and performed a T-test.

Results: At the estimated age of the right and left mandibular canines determined by the Kvaal formula, the T-test was performed showing a mean of 38.3 years for the right mandibular canine (Mean= 38.3; SD= 6.7) and 38.2 year the left mandi­bular canine (Mean= 38.2; SD= 8.9), with p = 0.910. Data analysis showed that there was no difference in age estimation using the Kvaal method on the right and left mandibular canines.

Conclusion: There was no difference in age estimates by the Kvaal method on the right and left mandibular canines.
