“…Assessing maturational status, regardless of whether the pubertal growth spurt of that patient has been reached or completed, can have a considerable influence on the diagnosis, treatment goals, treatment planning, and eventual outcome of orthodontic treatment. [1][2][3][4] Considerable variations in development among children of the same chronological age have led to the concept of biologic or physiologic age. Physiologic age is the registry of the rate of progress toward maturity that can be estimated by somatic, sexual, skeletal, and dental maturity.…”

Objective: To estimate dental maturity using the Demirjian Index for the mandibular third molar and investigate the relationships between dental maturity and skeletal maturity among growing children. Methods: The samples were derived from panoramic, lateral cephalometric and hand-wrist radiographs of 270 female subjects registered as patients at the orthodontic department, dental hospital, Yonsei University. Dental maturity [Demirjian Index (DI)] and skeletal maturity [skeletal maturation indicators (SMIs)] and cervical vertebrae maturation indicators (CVMIs)] were estimated from these radiographs. Results: There was a significant correlation (r = 0.64) between SMIs and DI, and a similar correlation (r = 0.59) was observed between CVMIs and DI (p ＜ 0.001). If DI was above Stage E, then the SMI was above Stage 10 and the CVMI was above Stage 5. There was a weak correlation (r = 0.26) between age at menarche and DI (p ＜ 0.001). There was no significant difference in DI among Class I, II or III malocclusions. Conclusions:Dental maturity evaluation using the mandibular third molar will be an adjunctive tool in combination with cervical vertebrae and hand-wrist maturity evaluations.
