Morphological and microleakage studies of the cavities prepared by Er:YAG laser irradiation in primary teeth.

OBJECTIVE The purposes of this study were to investigate cavity surfaces morphologically, and compare microleakage at cavities prepared by Er:YAG laser after composite resin restoration versus conventional mechanical treatment in human primary teeth in vitro. BACKGROUND DATA There have been few reports on microleakage at cavities prepared by Er:YAG laser… (More)
