摘要
牙釉质发育不全症(AI)是一种遗传性疾病,其特征是牙釉质的形态和结构发生变化。目的:根据扫描电子显微镜和显微层析成像分析,重点介绍在患有低钙化 AI 的牙齿中观察到的形态变化。病例报告:一名成年男性的牙齿因低钙化 AI 而严重受损。治疗方案包括拔除第三磨牙,然后进行修复治疗。拔牙后,对牙齿进行了扫描电镜和 X 射线显微层析成像(microCT)分析。有 AI 的牙齿显示出从珐琅质外表面到中心排列的微裂纹。微裂纹呈龟裂或 "裂地 "状。扫描电子显微镜证实了微裂纹的存在以及某些区域釉质棱柱方向的扭曲。结论低钙化性釉质发育不全IIIA亚型患者的牙齿显示出明显的结构变化,这与骨折的难易程度密切相关。
Case Repor Case Report and X t and X-ray Microtomography and Scanning Electr aphy and Scanning Electron Microscopy Analysis of Teeth with Hypocalcified Amelogenesis Imperfecta
Amelogenesis imperfecta (AI) is a genetic disease characterized by producing morphological and structural changes in tooth enamel. Objective: To highlight the morphological changes observed in teeth with hypocalcified AI based on scanning electron microscopy and microtomography analysis. Case report: An adult male had teeth seriously compromised by hypocalcified AI. The treatment plan involved removal of third molars followed by restorative and prosthetic treatment. After extraction, the teeth were analyzed by SEM and X-ray microtomography (microCT). Teeth with AI revealed the presence of microfractures arranged from the outer surface to the center of the enamel. Microfractures had a cracked or “cracked ground” pattern. SEM confirmed the presence of microfractures and distortion in the orientation of the enamel prisms in some regions. Conclusion: Teeth of patients with hypocalcified amelogenesis imperfecta IIIA subtype show significant structural changes that are closely related with the ease of fractures.
