EFFICACY OF PHOTODYNAMIC THERAPY AS AN ADJUNCT TO NON – SURGICAL PERIODONTAL THERAPY IN TYPE-2 DIABETES MELLITUS PATIENT

Background: To Evaluate the additional benefit of Antimicrobial Photodynamic therapy, if any in the glycemic control of type 2 diabetes mellitus chronic periodontitis patients . Methods: Fifty diabetic patients with chronic periodontitis were taken for the study who met the inclusion criteria of clinical attachment loss ?3 to 5 mm at ? 30% of sites and bleeding on probing present in two different quadrants . After SRP ( Scaling and root planing ) , one quadrant was selected for aPDT while other served as a control group. Clinical parameters i.e. Plaque index, Probing depth ,Relative attachment level and HBA1c were measured at baseline, 1 week , 1month and 3 months. Results: Statistically significant differences in the mean probing depth, Relative attachment level, plaque deposit, and HBA1c were found between baseline and 12 weeks post-treatment for both groups. No significant differences in glucose levels were detected among the two groups in 1 week . Reduction in the mean HbA1c level after treatment was observed in both groups in 1 month and 3 months . Conclusion: Antimicrobial Photodynamic Therapy when used in addition to scaling and root planing yields significant improvement of mean probing depth , Plaque deposit ,Relative attachment levels, periodontal status and reduction of HbA1c levels in treatment of diabetic patients with periodontitis when comparing the test group to the control group.
