Introduction: Chronic periodontitis is treated routinely by scaling & root planing. An innovative therapy represented by the irradiation of periodontal pockets with laser & photodynamic therapy can be considered as a promising novel approach for eradicating pathogenic bacteria in periodontitis.
Aim and Objectives: To compare the efficacy of Diode laser & Photodynamic therapy with SRP and SRP alone in chronic periodontitis patient.
Methodology: A total of 11 patients aged between 30 – 50 years diagnosed as chronic generalised periodontitis were selected for the study & grouped as:
- Group 1 (10 sites were treated with scaling and root planing alone).
- Group 2 (10 sites were treated with scaling and root planing followed by diode laser therapy),
- Group 3 (10 sites were treated with scaling & root planing followed by methylene blue mediated photodynamic therapy)
The clinical parameters were evaluated at baseline, 1st week & 3rd week interval after therapy, Subgingival plaque samples were collected using sterilized curette and total bacterial count were evaluated.
Results: Significant reduction in clinical & microbial parameters was seen in group 2 and group 3 i.e., reduction in mean CFUs, However, greater statistically significant reduction was observed in group 3.
Conclusion: Photodynamic therapy is a valuable treatment modality adjunctive to conventional scaling and root planing in comparison with diode laser therapy.
