LOW-LEVEL LASER PERIODONTAL THERAPY IN DIABETIC PATIENTS A RANDOMIZED CONTROLLED CLINICAL TRIAL - PILOT STUDY

Abstract

Objectives We aimed to evaluate the effects of low-level laser therapy as an adjunct to non-surgical periodontal therapy in patients with periodontitis and compare the effect on periodontal healing in diabetes mellitus and non-diabetes mellitus patients. Methodology Ten patients with periodontitis stage II grade B were divided into two groups; Group 1 included 5 non-diabetes mellitus patients with periodontitis, and Group 2 included 5 type-2 diabetes mellitus patients with periodontitis. A 13 mW low-level laser was used in a continuous wave and non-contact mode as an adjunct to scaling and root planning (SRP) in a split-mouth study design “OPTODAN” (Scientific Development and Production Center, Saratov, Russia). The clinical parameters; plaque and gingival index, probing depth, and relative clinical attachment level of the test and control sides of both groups were analyzed at baseline and 1-month post-therapy. Visual analogue scale was used to determine patient discomfort intraoperatively and after 1 week. Results Statistically, significant improvement was evident in the gingival index, probing depth, and relative clinical attachment level when comparing test and control sides in all patients 1-month post-therapy. There was improvement in gingival index amongst type-2 diabetes mellitus patients in the test group. However, non-diabetes mellitus patients demonstrated superior results especially in probing depth and relative clinical attachment level. Conclusion The use of low-level laser therapy as an adjunct in periodontal therapy showed overall improvement in gingival inflammation, probing depth, and clinical attachment level. In comparison to non-diabetes mellitus patients, type-2 diabetes mellitus patients demonstrated significant improvement in gingival inflammation with low-level laser therapy.
