PHOTODYNAMIC THERAPY AS AN ADJUNCT TO SCALING AND ROOT PLANING IN CHRONIC PERIODONTITIS PATIENTS: A SPLIT MOUTH CLINICO MICROBIOLOGICAL STUDY

Abstract

Photodynamic therapy (PDT), which involves the use of low power lasers with appropriate wavelength to kill cells or microorganisms previously treated with a photosensitizer drug.¹ The aim of the present study was to  assess the efficacy of photodynamic (PDT) as an adjunct to non –surgical periodontal therapy (SRP) for the treatment of chronic periodontitis. Materials &Method: A split mouth design was used in A total of 20 patients (as per the criteria laid down for selection), 3quadrents were selected in each patient and divided in to three groups. Group A:  Received Photodynamic Therapy by means of 0.5% indocyanine green and irradiated by Laser after scaling and root planing. Group B:  Received scaling and root planing. Group C: Received laser therapy. The clinical readings and the microbial analysis were done at base line, 1 month and 3 months from the 1st visit. The pre and post-operative values of all parameters were subjected to statistical analysis. Conclusion: PDT+SRP group showed additional improvement than the SRP groups in all parameters were as the results were low in LASER alone group.
