Laser-assisted cavity preparation and adhesion to erbium-lased tooth structure: part 2. present-day adhesion to erbium-lased tooth structure in permanent teeth.

摘要: With the introduction of Er:YAG laser, it has become possible to remove enamel and dentin more effectively efficiently than with other lasers. Thermal damage is reduced, especially in conjunction water spray. Since FDA (Federal Drug Administration) approval laser 1997--for caries removal, cavity preparation conditioning tooth substance - there have been many reports on use this technique combination composite resins. Moreover, pretreatment (laser etching) proposed as an alternative acid etching dentin. Reports evaluating adhesion glass-ionomer cements Er:YAG-lased are scarce. This article reviews literature regarding sealing efficacy using different (pre)treatment protocols association preparation. Recent research shown that lasing may result surface subsurface alterations negative effects both seal. It concluded at present, advisable respect conventional procedures needed for respective adhesive materials. Although majority present day show microleakage bond strength negatively influenced by (compared preparation), ongoing discussion how best achieved surfaces.
