Sažetak
AIM: To determine the correlation between tooth calcification, cervical skeletal maturity and chronological age (CA) in children, and to analyze if some teeth can be used as a marker for skeletal maturity and CA estimation. MATERIALS AND METHOD: Panoramic dental images and lateral cephalograms of 231 orthodontic patients (127 girls, 104 boys) aged from 5.9 to 15.8 years. Skeletal maturity was assessed using Baccetti’s cervical vertebral maturation (CVM) method. Tooth calcification stages of the first seven mandibular teeth from the left side were determined using the scoring system of Demirjian. Correlation among calcification stages, skeletal maturity stages and CA was assessed using Spearman rank correlation coefficients. RESULTS: A positive correlation between dental maturity and cervical vertebral maturity was found for the mandibular second premolars (rho = 0.684, P ˂ 0.001), second molars (rho = 0.674, P ˂ 0.001), first premolars (rho = 0.664, P˂ 0.001), and canine (rho = 0.574, P˂ 0.001) teeth. The lowest correlation was found for the first incisors and the first molars. There was a high positive correlation between dental stage development and CVM stages. Demirjian’s method overestimated the age of girls by 1.24 ± 1.03 years, and the age of boys by 0.80 ± 1.03 years. Willems’ method overestimated the age of girls by 0.36 ± 0.98 years, and that of boys by 0.44 ± 0.98 years CONCLUSION: Mandibular premolars and second molars are the most valuable indicators for skeletal maturation stage, while both dental age methods overestimated the CA of the sampled children
