Accuracy of Demirjian and Willems Methods for Age Estimation of Children from Northern Argentina
Journal Title: Journal of Clinical and Medical Research - Year 2019, Vol 1, Issue 1
Abstract
The dental development is widely used to estimate the chronological age; one method frequently used is that of Demirjian, applied in Franc-Canadian children, and the other is that of Willems, adapted from the first one to Belgian children. Demirjian uses scores according to the degree of calcification of the seven permanent mandible teeth of the left side; Willems adapts to years the scale of scores of Demirjian. Objective: To analyze the accuracy in determining the chronological age through the degree of dental calcification using the methods of Demirjian and of Willems in children from Tucumán, Argentina. Methods: 66 children (29 female and 37 male) who assisted to radiological studies previous to the dental treatment were selected. Panoramic X-rays were taken. Dental ages were calculated using the corresponding tables of the methods of Demirjian and Willems. Chronological ages were calculated between the date of birth and the date of the study. The statistical paired t-test was used. Results: Through the method of Demirjian the mean of the differences was 0.44 ± 0.96 for girls and 0.49 ± 1.02 for boys, being significant differences between both genders. The method of Willems was more accurate than that one of Demirjian (-0.08 ± 0.92 for girls and 0.19 ± 0.94 for boys), being no significant differences between the dental and the chronological ages. Conclusion: According to these results both methods could be used to estimate the chronological age through the observed dental calcification in radiographic images of children from northern Argentina. Nevertheless, greater statistical accuracy with the method of Willems would be reached for both genders.
