釉质发育不全(amelogenesis imperfecta,AI)是一种与全身发育缺陷无关的遗传性釉质病变。根据临床表现,它分为3种类型:发育不全型(hypoplastic AI,HPAD、成熟不全型(hypomaturation AI,HMAI)和钙化不全型(hypocalcified AI,HCAI)。其中HCAI具有钙化不全的褐黄至桔黄色釉质,此牙本质的X线阻射性还低。本文应用免疫化学和生物化学技术研究了3例HCAI患者釉质中的可吸收蛋白。 材料和方法 3位独立的HCAI患者,男性2名,女性1名,女性釉质样本取自阻生的第三磨牙,男性取
Amelogenesis imperfecta (AI) is a hereditary enamel lesion unrelated to systemic defects. According to the clinical manifestations, it is divided into three types: hypoplastic AI (HPAD), hypomaturation AI (HMAI) and hypocalcified AI (HCAI), in which HCAI has calcareous yellow-orange to orange enamel , The dentin X-ray barrier is still low.In this study, three cases of HCAI patients with enamel absorbable proteins were studied by immunochemical and biochemical techniques.Materials and methods Three independent HCAI patients, male 2, female 1 Female enamel samples were taken from the impacted third molars, and the male fetuses were taken
