摘要/Abstract

摘要： 目的: 评价超快激光去除牙科用树脂粘接剂的效果和安全性。方法: 在离体牙表面制备粘接层样本,使用超快激光间隔扫描方式进行加工。光镜和电镜下观察粘接剂表面形貌,拉曼光谱检测粘接剂成分变化,光镜下观察牙体截面损伤情况。结果: 经超快激光加工后,粘接剂发生碳化。随着激光参数的变化,出现不同程度的色泽改变和体积膨胀,无外力作用下即可从牙面脱落。粘结剂层下方釉质无明显损伤。结论: 超快激光可安全有效地去除釉质表面树脂粘接剂。

Abstract: PURPOSE: To investigate the effect and safety of removing dental resin adhesive with ultrafast laser. METHODS: Resin adhesive layers were prepared on the surface of extracted teeth and processed with ultrafast laser scanning. Morphology was observed under optical microscope and scanning electron microscope. Component change was tested with Raman Spectrometer and dental tissue damage was observed through sample sections. RESULTS: After laser processing, resin adhesive showed significant change in colour and volume expansion along with laser parameters. Dislodgement happened without any external force. Carbonization was presented in Raman spectroscopy result. No obvious damage was observed in enamel underneath. CONCLUSIONS: Ultrafast laser can be used to remove dental resin adhesives on the enamel.

Key words: Ultrafast laser, Ultrashort pulse laser, Resin adhesive
