Aims: To assess dental maturation in children with amelogenesis imperfecta (AI) and compare their estimated dental age with the age of non-AI children. Methods and results: Panoramic radiographs of children with (n = 27) and without (n = 54) AI were retrospectively collected in the ratio of 1:2. The former consisted of case group, while the latter figured as control group. Both groups were paired by sex and age (P >.05). Dental maturation was assessed in each radiograph using Demirjian's staging technique and Willems’ method. Intra- and interexaminer reproducibility reached >0.8. The mean estimated dental age in subjects with AI was 12.5 ± 2.69 years, while in subjects without AI it was 11.73 ± 2.48 years (P =.21). The comparison of mean chronological (12.26 ± 2.6 years) and estimated dental age (12.5 ± 2.69 years) in subjects with AI did not reveal statistically significant differences (P =.38). Conclusion: This study highlights the similarity of dental maturation between subjects with and without AI from the radiographic perspective of crown-root formation.
