Paper Abstract

Data are presented from a multi-center, prospective, longitudinal, clinical trial comparing four different treatments for periodontitis, (1) the LANAPTM protocol utilizing a FR pulsed-Nd:YAG laser; (2) flap surgery using the Modified Widman technique (MWF); (3) traditional scaling and root planing (SRP); and (4) coronal debridement (CD). Each treatment was randomized to a different quadrant. Fifty-one (54) subjects were recruited at five centers that included both private practice and university-based investigators. At 6-months and 12 months post-treatment the LANAPTM protocol and MWF yielded equivalent results based on changes in probing depths. The major difference observed between the two procedures was that patients reported significantly greater comfort following the LANAP™ procedure than following the MWF (P<0.001). There was greater reduction in bleeding in the LANAPTM quadrant than in the other three at both 6 and 12 months. Improvements following SRP were better than expected at 6 months and continued to improve, providing outcomes that were equivalent to both LANAPTM and MWF at 12 months. The improvement in the SRP quadrants suggests the hypothesis that an aspect of the LANAPTM protocol generated a significant, positive and unanticipated systemic (or trans-oral) effect on sub-gingival wound healing.
