“…Maturation indicators, such as skeletal maturation, dental development, menarche, voice changes can be used in this matter. Th e age of menarche in girls and appearance of characteristic sexual signs in boys are most closely associated with peak high velocity, but they appear to have no correlation with dental development [1,9].…”

Background: Dental age assessment is very useful in the pediatric dentist's and orthodontist's everyday practice. The eventual lack of correlation between dental age, skeletal maturation and chronological age can infl uence treatment procedures regarding mostly their application time. The aim of our study was to investigate the relationship between dental age based on the calcifi cation stages of the fi rst lower premolar (PM1i) and skeletal maturity stages using cervical vertebrae (C2, C3, C4) among Romanian individuals and to determine the clinical value of the fi rst premolar as a growth evaluation index. Material and methods: In a sample of 30 patients (13 males, 17 females) ranging in age from 9 to 15 years (mean age 11.2 years) we examined the orthopantomography radiographs (OPT) and lateral cephalometric radiographs of each case. Results: The biological development of girls is about 1.5 years more advanced than in boys. When the Demirjian Index was at stage F, then CVS was at stage 3.4, which means that in developmental stage "F" (according to Demirjian index) premolars are indicators of the optimal time for orthodontic treatment. We found a signifi cant correlation (R = 0.871, p <0.001) between CVM and Demirjian's index. Conclusions:The correlation shown in this study will allow clinicians to use mandibular fi rst premolar as an adjunctive tool to assess adolescent growth spurt, combined with the evaluation of the cervical vertebrae. The results also show the usefulness of the assessment of the development of dental status as a simple diagnostic test to determine the biological age of the population.

“…Knowing the moment of the active growth of a child is important and useful for both paedodontic and orthodontic everyday practice [1]. Considerable variations in development among children of the same chronological age have introduced the concept of biological or physiological age [2].…”

“…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.
