We observed the clinical status of periodontal tissues after periodontal flap surgery combined with Nd:YAG laser irradiation based on clinical parameters.
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.
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.
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.
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. Nihon Shishubyo Gakkai Kaishi (J Jpn Soc Periodontol) 48 : 307-314, 2006.
