Introduction: Age estimation is an important part of forensic Odontology and orthodontic treatment planning. Environment have been proved to have an effect on growth. Since Willems’s dental age estimation has not been studied in southern Iranian population, the aim of the present study was to assess the correlation of chronological, dental and skeletal age in Bushehr in 2020.
Methods: In the present cross-sectional study, 85 pair of orthopantograms and cephalograms of 8-17 years old children and adolescents were selected. Dental age was determined using Willems’s method and skeletal maturation was determined using the cervical vertebrae method. Tooth malformation, pathologic conditions involving roots, present orthodontic treatment and images with low quality were excluded. Two dental interns, a radiologist and an orthodontist did the interpretations separately. Dental age and skeletal maturations were compared among students and specialists.
Results: Of 85 samples, 34 were for boys and 51 were for girls. The mean chronological, and dental age was 12.82±2.38 and 13.16±2.83 respectively. The mean difference was 0.34±1.30. Dental and chronological age had a strong correlation (0.880) in the present study. The correlation between students and specialists in determining skeletal age was overall moderately and strong (0.60-0.80). The correlation between students and specialists in determining dental age was overall very strong (more than 0.90).
Conclusion: The Willems’ method was applied in determining the age of the samples in the present study. The correlation between students and specialists in determining dental age was overall very strong, showing that dental age estimation using calcification stages is easier than the cervical vertebrae maturation method.
