Background: Diode laser with a wavelength of 810 nm or 910– 980 nm, does not interact with dental hard tissues. The present study was conducted to evaluate clinically the treatment outcomes following laser-assisted and conventional open flap surgical procedures. Materials & Methods: 20 patients with chronic periodontitis were divided into 2 groups. Group I were treated with soft tissue diode (980nm) laser and group II patients were managed with conventional open flap debridement. Parameters such as gingival index (GI), plaque index (PI), and probing pocket depth (PPD) was recorded. Results: Gingival index at baseline was 3.20 and 3.34, at 3 months was 2.40 and 2.64 and at 6 months was 1.14 and 1.82 in group I and group II respectively. Plaque index at baseline was 1.18 and 1.26, at 3 months was 1.00 and 1.12 and at 6 months was 0.78 and 1.00 in group I and group II respectively. The difference was significant (P< 0.05). Conclusion: Laser assisted flap procedures showed better treatment outcomes as compared to the conventional open flap debridement. Key words: Conventional open flap, Laser, Periodontitis
