Introduction: Guided tissue regeneration (GTR) describes procedures attempting to regenerate lost periodontal structures through differential tissue responses. It typically refers to regeneration of lost periodontal attachment through use of bone grafts and barrier membranes, which further aid in clot stabilization, space maintenance and cell exclusion. Adjunctive use of lasers can provide the beneficial dual ablation of outer oral epithelium as well as bactericidal effect, thus promoting regeneration.

Aim: To evaluate the bactericidal effect of 10,600 nm carbon dioxide (CO2) laser in periodontal flap surgery and guided tissue regeneration procedure.

Materials and Methods: 15 patients were included in the split-mouth study. An acrylic stent was prepared to measure RAL, and with the help of UNC 15 probe, pocket depths were measured at baseline and at 3 months. Open flap debridement (control) versus CO2 laser with OFD (test group) with follow up performed on 1st day, 7th day and 3 months post operatively. In the test group, CO2 laser was used to lase the outer and under surfaces of the flap once reflected. At baseline and at 3 months, microbiological examination was carried out for which 2% 25 number sterile paper points were used to collect subgingival plaque samples from the deepest pockets in each group.

Results: The results in all parameters viz., RAL, Mean CFU, Pain perception through VAS, Bleeding on probing, Epithelial healing were statistically significant.

Conclusion: In this study, irradiation with CO2 laser not only caused guided tissue regeneration effect and bactericidal effect but also aids in gingival depigmentation if necessary.
