Accuracy of Demirjian’s and Cameriere’s Methods for Age Estimation in 6- to 10-Year-Old Iranian Children Using Panoramic Radiographs

Abstract

Objective. This study assessed the accuracy of Demirjian’s and Cameriere’s methods for age estimation in Iranian children using panoramic radiographs. Materials and Methods. This cross-sectional study evaluated 212 panoramic radiographs of 6- to 10-year-old children retrieved from the archives of an oral and maxillofacial radiology department from 2011 to 2017. The chronological age of children at the time of radiography was determined by subtracting the date of radiography from their birth date. The developmental stage of 7 permanent left mandibular teeth was determined according to Demirjian’s method. The stage of dental maturation was determined according to Cameriere’s method by using the normalized values for 7 permanent left mandibular teeth and the number of teeth with complete root development. The error value of the two methods was calculated by comparing them with the actual chronological age of male and female children, and the absolute error values of the two methods were compared with paired t-tests. Results. The mean error value of Demirjian’s and Cameriere’s methods was found to be 0.84 and −0.06 in girls and 0.93 and 0.04 in boys, respectively. Significant differences were noted in the absolute error of the two methods compared with the chronological age of male and female children (both P s < 0.001 ). Conclusion. In conclusion, this study indicated that Cameriere’s method was more accurate than Demirjian’s method for age estimation in Iranian children.

Dental Radiography in Age Determination: Contemporary Methods and Trends

“…However, certain studies have raised concerns about its potential for age overestimation (10,45,71,83,92) , while the Willems method, modified from Demirjian's, has demonstrated greater accuracy in some studies (14,71,82,92,130) but yielded contrasting results in others. (13,15) The assessment of open apices, as pioneered by Cameriere, is also extensively employed and has been reported to provide more accurate age estimations compared to Demirjian (101) and Willems in some instances, although another has noted potential age underestimation. (72) The second choice for age determination (23.1%), employed when all teeth have fully developed, involves assessing anatomic changes.…”

Estimation of Dental Age by Mandibular Third Molar Through Digital Orthopantomogram Using Modified Demirjian Method In South Indian Population Visiting A Dental College- A Retrospective Study

“…Of them, the Demirjian et al scoring system has been the subject of much study worldwide. The capacity of third molar maturation graded by Demirjian's approach to determine whether an individual has acquired medicolegally significant age has been more or less confirmed, notwithstanding its utility in estimating the age of young adults [5].…”
