Comparison Between Conventional Scaling and Laser Removal of Subgingival Calculus: An In Vitro Pilot Study

Mark Levin/R. Roll-Avrahami

The aim of this study was to examine the results of two techniques for removal of subgingival calculus from root surfaces. The Er:YAG laserís ability and efficiency to remove subgingival calculus was compared the traditional manual curettage technique. Three freshly extracted molars with a band of subgingival calculus were cleaned on one side with the Er:YAG laser (Opus 20, Opusdent, Natania, Israel) at 100 mJ and 20 pps, and on the other side with curettes. The teeth were coated with gold and prepared for SEM examination. The root surfaces that were cleaned with the Er:YAG laser featured a clean, smooth topography with no roughness, craters, or dentin exposure. The root surfaces that were manually cleaned with curettes featured some unevenness with shallow grooves. The use of the Er:YAG laser as a modality for calculus removal seems promising and efficient. Further research is required to verify the safety of this method and to devise tips that would allow convenient access to all sides of the tooth.
