Radiographic analysis of dental maturation in children with amelogenesis imperfecta: A case‐control study

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.
