It is the purpose of this study to observe the surface modifications produced by this method. Background data: Many techniques have been developed to facilitate bonding of various materials to dentin. However, an optimal bond has not yet been achieved. Methods: Four teeth ground to dentin were randomly assigned to two groups. Group 1: Er,Cr:YSGG laser treatment; and Group 2: laser treatment while a 100μm aperture stainless steel mesh was situated over the dentinal surface. Results: Group 1 samples appeared rugged but relatively flat. Group 2 samples presented a surface with uniformly aligned craters ∼100 μm wide, 150 μm deep. Conclusions: Masking the dentinal surface with a stainless steel mesh during laser irradiation produces a surface texture that appears to facilitate mechanical retention.3enjournal article
