From: The evaluation of healing effect of low-level laser treatment following gingivectomy
Graphical presentation of gingival wound healing for laser (test) and control groups during the study period. At day 1, all cases showed same healing (score 0). Starting from day 3, better healing was observed in laser than control group (score 2). Score 0: control and laser-treated sites showed the same healing extent. Score 1: better healing was observed for control than laser treated sites. Score 2: better healing was observed for laser treated than control sites. (* significant difference, p < 0.05)
