Aim: To compare effect of vertical internal mattress suturing and continuous independent sling suturing techniques applied in open flap debridement for treatment of periodontitis, on height of interdental papilla and periodontal wound healing in the esthetic zone. Materials and methods: 40 patients having chronic periodontitis were divided randomly into two groups. In test group (n=20) vertical internal mattress sutures and in control group continuous independent sling sutures (n=20) were placed. Clinical parameters at baseline, 3months and 6 months were assessed. Results: Interdental papilla height was maintained with vertical internal mattress sutures whereas significant (p≤0.05) papillary recession was observed with continuous independent sling sutures at 6 months follow up. Results in terms of periodontal wound healing showed consistently statistically significant improvement which was comparable in both the groups at 3 months and 6 months most post-surgery. Conclusion: Outcome of flap closure by vertical internal mattress suturing technique are better for maintaining papilla height than continuous independent sling suturing technique while wound healing in terms of improvement in clinical parameters were comparable for both the groups.
