Laser use and applications in dentistry has increased dramatically in the last
years. Laser etching of enamel may provide an alternative for conventional acid etching. The aim of this
study was to evaluate, under Scanning Electron Microscope(SEM),
enamel surface morphology after
laser irradiation with or without the addition of photoabsorber (black ink); with or without acid etching.
laser enamel etching produced surface
roughness that might be used for the infiltration and subsequent mechanical retention of resin.
