Efficacy of Low Level Laser Therapy in Periodontal Surgery-An Original Research

Abstract

Introduction: Lasers are the recent applications for the various procedures in dentistry. Hence in the present study we aim to evaluate the consequence of low-level laser therapy (LLLT) as an adjunct to periodontal therapy of those with the tobacco habits and having moderate to advanced chronic periodontitis.

Materials and Methods: Forty subjects were selected. They were divided to two groups of LLLT and control groups of 20 each. Diode laser was used for the adjunct non-surgical periodontal therapy applied to the gingival surface after periodontal treatment. These groups were further divided as those with tobacco habit and without habit. Gingival crevicular fluid was tested for Matrix metalloproteinase-1, tissue inhibitor matrix metalloproteinase-1, transforming growth factor-b1, and basic-fibroblast growth factor levels in the 1^st, 3^rd, 5^th months after treatment.

Results: Better improvement levels were shown by LLLT group in sulcus bleeding index, clinical attachment, probing depth levels compared to the control group (P <0.001). Significant progresses in the LLLT smokers’ PD and SBI levels compared to smokers of controls at all the months was seen. (P <0.001) Significant decrease in the marker levels at the time periods between both the groups was seen. (P <0.001) Basic-fibroblast growth factor levels significantly diminished in both groups in the first month after the treatment, then increased in the third and sixth months (P <0.005).

Conclusion: The periodontal non-surgical therapy with the low-level laser therapy can successfully be used for the periodontal health.
