- BACKGROUND: The degree of mineralization of permanent tooth germs in dental age assessment has been an area of interest among many authors for years. However, only recently have researchers attempted to determine the potential interdependencies between dental age and jaw relationships. The aim of this work was to compare dental maturation in patients with skeletal Class II to patients with skeletal Classes I and III. MATERIAL AND METHODS: The study involved 150 patients who sought orthodontic treatment. Dental age was assessed from panoramic radiographs using the Demirjian's method. Skeletal class was evaluated according to the value of the ANPg angle from the Björk's analysis. We used the analysis of variance (ANOVA) and the Student's t-test. RESULTS: The mean dental age in patients with skeletal Class III was significantly higher than the mean dental age in patients with skeletal Class II (p<0.0005). A correlation between the dental age and chronological age was established. The weakest correlation was seen between the dental age and skeletal Class II. Among patients with skeletal Class II, the strongest correlation was found between chronological age and the formation of the germ of the second lower premolar (r=0.67; p<0.001). CONCLUSIONS: Dental age among patients with skeletal Class II was the lowest.
