Abstract

Objectives: This study aims to compare the clinical efficacy of Modified Widman flap with and without adjunct laser in residual periodontal pocket treatment. Materials and methods: 200 teeth with sites probing ≥5mm and bleeding on probing from 20 periodontitis patients were randomly divided into two groups. Control group received Modified Widman flap therapy alone. Laser group was treated with Modified Widman flap and laser for photoablative inner/outer pocket de-epithelialization and photobiostimulative therapy. Clinical parameters PlI, GI, PD, and CAL were collected on baseline, 3, 6, and 9 months after treatment.  Wicoxon signed rank, Mann-Whitneyt, and Chi -square test were applied to analyze these data. Results: 9 months after surgery, the initial depth of the pockets ≥7 mm in the laser group decreased more (p<0.05) and achieved a higher percentage of closed pockets (p<0.05) compared to the control group. In smokers, the initial depth of the pockets ≥5 mm in the laser group was lower than that of the control group at all 3 time points after treatment. The difference in the percentage of pockets ≥6 mm between the two groups was statistically significant at T3 (p<0.05). Conclusion: Flap surgery combined with laser is beneficial for deep residual periodontal pockets and smokers in terms of pocket depth reduction.
