Comparison of the Demirjian Age with The Chronologic Age and Their Correlation.

Abstract

Background: People of French-Canadian descent were initially the major data source for Demirjian’s dental age estimate technique. However, due to chronologic variety, Dr. Acharya altered the data in 2011 to reflect the Indian population. The current study was conducted to improve the accuracy of Demirjian’s technique and to link Demirjian’s age with the chronologic age. Materials and Methods: A study of 300 participants was conducted in a dental college in Mathura, using orthopantomographs (OPGs) to evaluate dental maturity. The Demirjian 8 teeth method was applied, and chronological age was determined by subtracting the radiograph date from birthdate. Pearson’s correlation test was used to analyze the correlatution between chronologic age and Demirjian’s age. Results: Pearson’s correlation test revealed a significant correlation between chronologic age and Demirjian s age. The Demirjian s age has been overestimated in comparison to the chronologic age.
