Abstract

This study proposes a new application for the neodymium:yttrium-aluminum-garnet (Nd:YAG) laser in conservative dentistry, which is represented by the removal of collagen network from acid-etched dentin. Thirty extracted human upper premolars were selected to be given standardized buccal and lingual class V cavities. The teeth were randomly divided into three groups, each consisting of ten teeth: group 1, acid etch/Nd:YAG laser; group 2, acid etch/10% sodium hypochlorite (NaOCl); group 3, acid etch only. Five teeth from each group were prepared for the Masson trichrome technique, and the other five teeth were prepared for examination by scanning electron microscope. The results showed that the Nd:YAG laser can be used successfully as a novel method for removing collagen network from acid-etched dentin and can remove the collagen network more thoroughly than 10% NaOCl.
