Dental Age Estimation of 6-14-Year-Old Guilanian Children Using Demirjian's Method

Developing teeth may be evaluated based on the degree of tooth development or the stage of tooth eruption.
This study aimed to assess the accuracy of Demirjian’s method for dental age estimation in a group of Guilanian children.
Panoramic radiographs of 390 Guilanian children aged 6 - 14 years were analyzed based on Demirjian’s method. Dental age was compared with chronological age using a paired t-test. The difference between the estimated age and chronological age was examined by Mann Whitney test in males and females.
The mean difference between the dental age and chronological age was 0.84 in females and 0.82 in males (about 8 months). The difference in this regard between males and females was not significant. The difference between the chronological and dental age was significant in all age groups except for 13 - 13.99 years old.
Demirjian’s method may not be accurate enough for dental age estimation of Guilanian children and specific standards for dental age assessment should be developed for this population.
