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.

Mentions: The first author with 7 years of experience in assessing mineralization and eruption stages performed all DPRs assessments with appropriate magnification and contrast adjustment on all deciduous and permanent teeth on the left half of the maxilla and the mandible. When a problem was encountered for any reason in the assessment of one of the teeth, the tooth's counterpart on the other side was used. The permanent teeth were evaluated by the classification system described by Demirjian et al18 in eight stages, which we separated further into H stages, namely H1 (root length was complete, apical walls were converging, and approximately 1/2 of the apex closed) and H2 (apex was closed), thus modifying the system to have nine stages (Fig. 1).
