Aim: To evaluate the clinical and microbiological effects of diode laser used as an adjunctive therapy to scaling and root planing (SRP) to that of SRP and laser alone for the treatment of chronic periodontitis (CP).

Materials and methods: Forty patients with chronic generalized periodontitis were recruited for the study, out of which 120 sites are treated and grouped as follows: group I (40 sites were treated with SRP), group II (40 sites were treated with SRP followed by adjunctive diode laser therapy), and group III (40 sites were treated with diode laser alone). The following clinical parameters were evaluated at baseline and 10 weeks after therapy: gingival index (GI), plaque index (PI), probing pocket depth (PPD), and clinical attachment level (CAL). Subgingival plaque samples were collected into a vial containing 1 mL transport medium, i.e., thioglycolate broth medium and transported to laboratory for anaerobic culture.

Results: At 10 weeks, all groups demonstrated significant enhancements with respect to every single clinical parameter contrasted to baseline (all p < 0.05). There were no significant differences among groups as far as changes of clinical parameters in any time interval (all p > 0.05). Likewise at 10 weeks after treatment, the microbiological examination demonstrated a statistically significant reduction in bacterial count (BC) compared with baseline (p < 0.05), but there were no significant differences among groups with respect to BC in any time interval (all p > 0.05).

Conclusion: Taking everything into account, the present study demonstrated that the use of diode laser as an adjunct to conventional periodontal treatment (i.e., SRP) and diode laser alone demonstrated no extra advantages contrasted with conventional periodontal treatment (i.e., SRP).
