Abstract

Backgroung: The most prevalent method for determining the DENTAL AGE is the DEMIRJIAN METHOD. But, different studies have been showing that this method overestimates the age; so, Willems has presented a newer method. Willems has used (ANOVA) system to adapt DEMIRJIAN METHOD to Belgian Caucasian race. The result was new tables in sex separated. Calculating the overall maturity score by summing the adapted scores for the seven mandibular teeth directly results in the estimated DENTAL AGE. The purpose of this study is to determine the accuracy of WILLEMS METHOD in age estimation of children by radiography of developing teeth in Esfahan.Methods: In this descriptive, cross –sectional study, 151 panoramic radiographies belong to 54 boys and 97 girls at the age of 3 to 18 years old, were used. The sample of CHRONOLOGICAL AGE was obtained by subtraction of birth date from the radiography performance date.The sample of DENTAL AGE which was determined by both Demirjian and WILLEMS METHODs was entered to SPSS software (Ver 17) and the difference with the CHRONOLOGICAL AGE was analysed by using a t-test and ANOVA.Findings: The DEMIRJIAN METHOD resulted in an overestimation of 0.63 year (boys 0.94 year and girls 0.47 year).The new adapted method resulted in a smaller overestimation of 0.11 year (boys 0.22 year and girls 0.06 year). In different age groups, the minimum difference has been in the range of 11 to 12 years old and it was 0.01 year. The maximum difference has been in the range of 17 to 18 years old and it was 1.2 year.Discussion: The statistical difference between CHRONOLOGICAL AGE and WILLEMS METHOD is not significant. The adapted method was resulted in more accurate DENTAL AGE estimations in this population.
