A comparison of dental maturation in twins

Aim: The aim of the study was to assess the correlation between dental age among monozygotic (MZ) and dizygotic (DZ) twins. Materials and Methods: Panoramic radiographs of 156 twins, aged between 6-16 years (mean age 10.44 ± 2.72 years), divided into a group of 48 MZ and 108 DZ. Dental age was assessed by Willems method. BMI was determined for each patient. Wilcoxon signed rank test and Mann-Whitney U test were used for statistical analysis. The significance level was set to be 0.05). The dental age of MZ twins was more similar than DZ twins in the 6-9 year age group (p
