<p><strong><span style="color: #ff0000">Introduction:</span></strong><br>
Determining the skeletal age and remaining growth potential of patients are important factors in orthodontic treatment. Evaluating cervical vertebrae development is a reliable method for determining skeletal age. This study aimed to evaluate the correlation between dental calcification and stages of skeletal maturation.<br>
<span style="color: #ff0000"><strong>Materials and methods:</strong></span><br>
This descriptive cross-sectional study was conducted on 84 panoramic radiographs and lateral cephalometrics related to 10–15-year-old patients without<br>
systematic diseases affecting dental calcification and development. Patient’s skeletal age was determined by the stage of cervical vertebrae development and by using Lamparski’s method. Dental age of samples was determined by Demirjian’s method. Findings were analyzed by SPSS 18 software using Spearman’s correlation test to determine the correlation between the cervical vertebrae development and the dental development stages. P < 0.05 was considered significant.<br>
<span style="color: #ff0000"><strong>Results:</strong></span></p>
<p>Spearman’s correlation test showed a significant direct correlation between dental age and skeletal age (r2 = 42.5%). The linear relationship between dental age and skeletal age was significant (p < 0.05). The highest correlation coefficient was between the cervical vertebrae development and the stages of mandibular second premolar calcification in girls (rs = 0.609) and in the second molar in boys (rs = 0.471). In Demirjian’s method, stage G of the mandibular second premolar teeth in girls and stage F of the mandibular second molar teeth in boys nearly coincided<br>
with the pubertal growth spurt.<br>
<span style="color: #ff0000"><strong>Conclusion:</strong></span></p>
<p>The findings of this study showed that, in Demirjian’s method, stage G of the mandibular second premolar teeth in girls and stage F of the mandibular second molar teeth in boys was most frequent between developmental stages. According to the relatively high correlation coefficient between the dental age and the skeletal age, using dental calcification stages by panoramic radiography may become a simple first-level diagnostic test to determine skeletal maturity, which requires more studies in different ethnicities and places all around the world.</p>
