Dental Age Assessment Using Demirjian and Cameriere’s Methods In an Iranian Population During 2017-To 2018

The present study aimed to compare the two dental age (DA) estimation methods of Cameriere and Demirjian among 6-14 year-old children in Tehran in 2017-2018. This cross-sectional analytical study involved 306 panoramic images from 153 girls and 153 boys. The DA of participants was estimated by Cameriere’s and Demirjian’s methods. The data were statistically analyzed by the paired sample t-test, repeated measures ANOVA, and the independent t-test. Finally, a formula suitable for Iranian society was developed based on the results of regression analysis. The mean age estimation error was +0.89 years for Demirjian’s method (+0.86 in boys and +0.93 in girls) and -0.20 years for Cameriere’s method (-0.20 in boys and -0.10 in girls). There was a significant difference between the DA calculated by Cameriere’s and Demirjian’s methods and the chronological age. There was no significant difference between Cameriere’s and Demirjian’s methods in this context. The formula developed in this study could estimate the age of participants with an accuracy of above +0.008 (+0.009 in boys and +0.006 in girls). However, the results indicated no significant difference between the proposed formula and Cameriere’s method in the accuracy of age estimation.The accuracy of Cameriere’s method was higher than that of Demirjian’s method, but the formula proposed for Iranian society was more accurate than both of them. The Cameriere method underestimated and the Demirjian method overestimated the age.
