Dental Age Estimation of 6-15 Year Old Indian Children Using Demirjian Method

Shekhar Grover, Tanu Anand


Objective: Assessment of tooth development to estimate the age of living subjects is
required in various disciplines including pediatric dentistry, orthodontics, and forensic
dentistry. The most widely used method is the one given by Demirjian et al. in 1973.
This method has been tested only a few times in North Indian children, thus the need
for present study.
Methodology: Seven left mandibular teeth were assessed from 215
orthopantomograms (OPGs) belonging to healthy children aged 6–15 years randomly
selected and were staged according to Demirjian method. Univariate quantitative
analysis was performed.
Results: A general over-estimation of 0.61 years was observed (0.66 years – males and
0.56 years – females) (p <0.05). The gender differences were not statistically significant
(p >0.05). Also, younger age groups had a higher amount of overestimation.
Conclusion: The present results support the need for refinement of the populationspecific
standards in Demirjian method, for its further application.
