Abstract

We observed the clinical status of periodontal tissues after periodontal flap surgery combined with Nd:YAG laser irradiation based on clinical parameters.<BR>Materials were 52 teeth in 10 patients, Surgical procedure was as follows: the gingival flap was elevated and root planing and bone defect debridement were done. In the experimental group (Exp) of 26 teeth in 10 patients, Nd:YAG laser was irradiated to the root surface, the bone defect, and the inside of the gingival flap after root planing and bone defect debridement (3.0 w, 30 seconds, 3 times). the laser was also irradiated around the mucogingival junction immediately after surgery (1.5 w, 1 minute, 3 times). In the control group (Cont) of 26 teeth in 10 patients, the Nd:YAG laser was not irradiated combined with surgery.<BR>Clinical parameters were Probing depth (PD), plaque index (PLI), gingival index (GI), and bleeding on probing (BOP). Clinical and radiographic examinations were done before surgery and 3 and 6 months after. Clinical parameters were subjected to the Wilcoxon signed-rank test.<BR>No statistical by significant differences were seen between groups for clinical parameters after periodontal surgeriy and abnormal clinical signs such as gingival and bone necrosis and bone loss.<BR>Our findings indicate that after flap surgery combined with Nd:YAG laser irradiation, periodontal tissues healed uneventfully, enabling us to reduce probing depth and remove gingival inflammation.
