Abstract
Periodontal regeneration often requires surgical intervention, yet conventional procedures may lead to postoperative discomfort and inflammation, raising interest in diode laser-assisted therapy. Therefore, it is of interest to compare healing outcomes after Kirkland and Modified Widman flap surgeries performed with or without 976 nm diode laser exposures in 80 sites. Laser-treated groups showed greater reductions in probing depth and gingival inflammation, with Group B exhibiting the highest SBI reduction and Group D demonstrating the greatest CAL gain. Pain scores favored diode laser use, particularly in Group D on day 1. Diode laser adjuncts significantly enhanced clinical healing parameters and reduced discomfort, supporting their beneficial role in periodontal surgery.
