Abstract:
BACKGROUND AND AIM: This study was designed to assess the correlation between chronological age and modified Demirjian estimated dental age.METHODS: Panoramic radiographs of ۱۸۳ Patients between ۱۳.۵ and ۲۰.۵ years old were assessed for the developmental stage of lower right third molars. Student’s t-test was used to measure the same hypothesis of the chronological age and estimated modified Demirjian dental age described above and Pearson's correlation coefficient was used to measure the linear correlation between them.RESULTS: The result of the test at a significance level of ۹۵% led to the hypothesis. There was not any significant difference between estimated dental age measured by chronological age compared to modified Demirjian method (P = ۰.۸۱). Pearson correlation coefficient between dental age in modified Demirjian's method and chronological age was calculated ۴۰%.CONCLUSION: The mean dental age in both male and female, was calculated ۰.۳۳ years less than chronological age.
