摘要
目的：观察漂白剂直接作用于牙颈部后牙的结构变化。方法：选用几种不同的漂白剂，直接作用于牙颈部，应用扫描电镜观察漂白剂引起的牙本质、釉质、牙骨质的结构变化。结果：牙颈部的牙骨质、牙本质均有结构上改变，釉质变化不明显。结论：提出预防牙颈部外吸收的措施，使临床上能安全。
Aim:To observe the structural changes by directly using bleaching agents on cervical hard tissues of teeth. Methods: SEM to observe the structural changes of cervical enamel, dentin and cementum after bleaching by different kinds of bleaching agents. Results: There were structural changes at cervical dentin and cementum. Conclusions: We suggested protective measures to prevent root resorption for clinical use effectively and safely.
