Bottom Line: It has been determined that the mixed dentition period ended with the shedding of the second deciduous molars in both genders.The dental charts presented here included information that could be beneficial to dental clinicians in making appropriate diagnosis and planning orthodontic and surgical procedures.These charts also provided datasets for preliminary dental age estimation in Turkish children and young adults.

ABSTRACT

Purpose: In this study, we aimed to develop dental charts for Turkish children and young adults of both genders within the age group of 4.5-22.5 years according to tooth mineralization and eruption in a format similar to that proposed by AlQahtani et al.

Materials and methods: In total, 753 digital panoramic radiographs from 350 males and 403 females were assessed. The permanent teeth were evaluated according to the classification system described by Demirjian et al. The eruption stage was assessed with Bengston's system, which was modified by AlQahtani et al at four points.

Results: Teeth generally developed earlier in females than in males. This was particularly notable in the age group of 5-14 years. However, this difference was usually visible in only one stage, not in all teeth. It has been determined that the mixed dentition period ended with the shedding of the second deciduous molars in both genders.

Conclusion: The dental charts presented here included information that could be beneficial to dental clinicians in making appropriate diagnosis and planning orthodontic and surgical procedures. These charts also provided datasets for preliminary dental age estimation in Turkish children and young adults.

Description and illustration reveals the eruption of permanent teeth by using Bengston's stages20 modified by AlQahtani et al.16 Position 1: When the occlusal or incisal surface is covered entirely by bone. Position 2: When the occlusal or incisal surface breaks through the crest of the alveolar bone. Position 3: When the occlusal or incisal surface is midway between alveolar bone and the occlusal plane. Position 4: Occlusal or incisal surface is in the occlusal plane.

Position 3: When the occlusal or incisal surface is midway between alveolar bone and the occlusal plane. Position 4: Occlusal or incisal surface is in the occlusal plane.

Mentions: Root resorption on deciduous teeth in the mixed dentition period was evaluated with Moorrees' system,19 modified by AlQahtani et al16 in four classification stages (Ac, apex closed; Res1/4, resorption of the apical quarter of the root; Res1/2, resorption of half the root; and Res3/4, resorption of three-quarters of the root). Eruption position was assessed with Bengston's system20 modified by AlQahtani et al,16 with alveolar bone eruption of the teeth considered in four positions (Fig. 2). After the assessment of the developmental and eruption stages, the median was identified from the minimum to the maximum stages for each stage and for each tooth. To find the median value, the mineralization and eruption stages were first determined according to their rating for each tooth, after which the data were sorted according to their value after all DPRs in that age range had been evaluated. The number in the middle was then chosen as the median value. That is, supposing that there were seven DPRs in the age group of 5 years and that the Demirjian stages of the first premolars were B, C, C, C, C, D, and D, then, the median value became the C stage. These medians were used to construct dental diagrams for both genders.
