Objective: This study aimed to evaluate the relationship between the calcification stages of permanent maxillary and mandibular canines and second premolars and skeletal maturity in both sexes. Methods: This study included 138 patients (82 females, 56 males) who were treated in the Department of Orthodontics, Altinbas University. The mean age of the patients was 12.31 +/- 1.76 years, ranging from 7.8 years to 15.8 years. Dental maturity stages of canines and second premolars were evaluated according to the Demirjian index on digital panoramic radiograph. The skeletal maturation stage was determined using the cervical vertebral maturation (CVM) index. The Pearson correlation analysis was performed to assess the association among CVM stages and calcification stages of canines, second premolars, sex, and chronological ages. Results: A statistically significant correlation was found between CVM and the calcification stages of the canines and second premolars (p<0.05). The calcification stages of the canines and second premolars had the highest distribution of Stage F and Stage G at CVM2 (p<0.01). For the canines and second premolars, Stage H corresponded to CVM3 in female patients and a high percentage of Stage G corresponded to CVM3 in the male group. Conclusion: A significant correlation was found between the calcification stages of maxillary and mandibular canines, second premolars, and skeletal maturity in both sexes. It was observed that calcification stages and cervical maturations were advanced in female subjects compared with male subjects.
