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.
