The aim of the present study was to analyze effects diode laser irradiation on healing human oral mucosa.After gingivoplasty, right hemi-arch (test group) 16 patients irradiated with a laser. left side (control not irradiated. Incisional biopsies were performed both sides at 7, 14, 21, and 60 days after surgery morphometrically analyzed by light microscopy.Epithelium width ranged from 260.6 393.5 microm. Volume densities basal (20.2%), prickle cell (55.6%), cornified (24.2%) layers remained stable. peak number neutrophils 6 cells/mm(2) mononuclear cells 44 cells/mm(2). Collagen fibers (80%) fibroblasts (14%) occupied main volume connective tissue. one-way ANOVA paired Student's t-test used for statistical analysis (P < 0.05).Low-level therapy did accelerate mucosa gingivoplasty.
