Abstract
Objective
Considering the genetic and physiological status of different geographical areas, different age estimation methods may produce different results. This study aimed to compare the 2 dental age (DA) estimation methods of Cameriere and Demirjian among 6- to 14-year-old children in Tehran in 2017-2018.
Study Design
This cross-sectional analytical study was conducted on 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 analysis of variance, and the independent t test. Finally, a formula suitable for Iranian society was developed on the basis of the results of regression analysis.
Results
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 regard. 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.
Conclusion
The accuracy of Cameriere's method was greater 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.
期刊介绍:
Oral Surgery, Oral Medicine, Oral Pathology and Oral Radiology is required reading for anyone in the fields of oral surgery, oral medicine, oral pathology, oral radiology or advanced general practice dentistry. It is the only major dental journal that provides a practical and complete overview of the medical and surgical techniques of dental practice in four areas. Topics covered include such current issues as dental implants, treatment of HIV-infected patients, and evaluation and treatment of TMJ disorders. The official publication for nine societies, the Journal is recommended for initial purchase in the Brandon Hill study, Selected List of Books and Journals for the Small Medical Library.
