“…The dental age estimations performed using the Demirjian method in Turkish children living in different geographical locations usually overestimated chronological age (9,11,13,14). Willems et al (10) published their revised maturity scores almost 25 years after Demirjian et al's study (8).…”

Background: Age-related legal problems are particularly common in underdeveloped parts of Turkey. Age determination is important in terms of both laws and penalties in the legal process. Objectives: The aim of the present study was to compare the validity of the Demirjian and Willems methods in southern Turkish children. Methods: In this retrospective study, panoramic radiographs of 745 southern Turkish children (382 boys and 363 girls) aged between 4 and 15.99 years were examined by one investigator. According to Demirjian and Willems method, the mean difference between chronological and dental age was calculated for each sex and age group. The Wilcoxon test was used to compare all data. Statistical analysis was performed to test the validity of Demirjian and Willems methods by comparing the mean estimated and chronological age. Results: The Demirjian's method overestimated age with a mean accuracy of 0.832 in females and by 0.923 in males, while Willems method overestimated it by 0.202 in females and 0.434 in males. Conclusions: The dental age estimation by Willems method was found to be more accurate than Demirjian method in contemporary Turkish pediatric population.

“…However, it is observed at all groups that crown-root formation earlier completed in the Turkish children and young adults. In previous studies conducted in Turkish populations, it has been reported that dentition shows gender differentiation, with that in females preceding that in males [13][14][15]17,19,21]. Karadayi et al [19] described that this difference was usually in only one stage and not in all teeth.…”

“…There are some studies in the literature evaluate the applicability of Demirjian method for Turkish population between 2010 and 2015 [13][14][15][17][18][19]. In all studies, the applicability of Demirjian method is not suitable for Turkish population [14,15,18] (Table 3).…”

“…Demirjian's dental age estimation method was done in a different nation successfully but French Canadian studies showing that French Canadian standards were not applicable for age estimation in a different population [5,[10][11][12]. Although several types of researches have performed with Demirjian method on Turkish population as yet no study has tested this modified Demirjian's method [4,[13][14][15].…”

Background: Age estimation is important in the fields of dentistry and Demirjian's method is used generally. Many different methods have been used to date and none of them meet the standards as Demirjian's method since 1973. However, this method may not be valid in some populations. The aim of this study is to evaluate the modified Demirjian's method on Turkish children and young adults. Methods:The scoring table of Demirjian has been modified to Turkish children -young adults and new dental maturity score were obtained. In addition, the effect of gender on the crown and root formation were assessed using the MannWhitney-u test and the table was created with divided into ages. The dental maturity of 848 healthy children and young adults (445 females 403 males) aged between 10 and 19 years were studied with dental panoramic tomograms. Two raters evaluated the right third mandibular molar according to development stages of Modified Demirjian's. Results:The crown and root formation were statistically significant in the 17.0-17.9 age group between females and males (P = 006). Descriptive analysis showed that F stage is the shortest period. Modified Demirjian method is adapted to the Turkish population. Conclusion:It is demonstrated that age estimation in Turkish children and young adults will be performed easier with Modified Demirjian method adapted to the Turkish population.

Applicability of the Demirjian method for dental age estimation in western Turkish children

Abstract: The applicability of the Demirjian method is not suitable for western Turkish children and western Turkish children have a lower degree of dental maturity than that observed in the eastern, northeastern and northern Turkish subjects.
