目的评估无釉发育不全（AI）患儿的牙成熟情况，并将其牙龄与非AI患儿的牙龄进行比较。方法与结果以1:2的比例回顾性收集患儿（n = 27）和（n = 54）的全景x线片。前者为病例组，后者为对照组。两组按性别、年龄进行配对（P < 0.05）。采用Demirjian分期技术和Willems方法在每张x线片上评估牙齿成熟度。检测器内部和检测器之间的重现性达到了bb0.8。AI患者的平均牙龄为12.5 +/- 2.69岁，未AI患者的牙龄为11.73 +/- 2.48岁（P = 0.21）。AI患者的平均年龄（12.26 +/- 2.6岁）和估计牙龄（12.5 +/- 2.69岁）比较，差异无统计学意义（P = 0.38）。结论本研究从冠根形成的影像学角度强调了人工智能患者和非人工智能患者牙体成熟的相似性。
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.
