EFFICACY OF PHOTODYNAMIC THERAPY AND LASERS AS AN ADJUNCT TO SCALING AND ROOT PLANING IN TREATMENT OF CHRONIC PERIODONTITIS
Introduction: Periodontal pockets possess some degree of challenge for nonsurgical periodontal therapy. Scaling and Root planning (SRP) alone may not be sufficient in cases where surgical therapy is not advised or performed. Recent studies have demonstrated and suggested the use of photodynamic therapy or antimicrobial Photodynamic therapy (aPDT)for the treatment of periodontal disease or infections. The aim of the study was to evaluate the effects of SRP alone and SRP+PDT for treatment of deep periodontal pockets.
Methods: Thirty patients with chronic periodontitis were taken for the study who met the iclusion criteria of periodontal pockets≥6mm and bleeding on probing present in two different quadrants. After SRP, one quadrant was selected for aPDT while other served as a control group. Clinical parameters i.e. Plaque index, Modified sulcular bleeding index, Probing depth and Clinical attachment level were measured at baseline, 1month and 3 months.
Results: All clinical parameters significantly improved in both groups after 1and 3 months. At 1 month, inter-group comparison was statistically significant for mSBI (0.83±o.39 for SRP+aPDT and 0.51±0.45 for SRP alone) and PD (1.75±0.86 For SRP+aPDT and 1.2±0.93 for SRP).At 3 months, no statistical difference was observed for mSBI(0.94±0.44 for SRP+aPDT and 0.70±0.42 for SRP)
Conclusion: Non-Surgical periodontal therapy when performed along with photodynamic therapy plays an adjunct or additional role in the treatment of chronic periodontitis.
