Aim of the study: To evaluate the effect of low-level laser therapy, as an adjunct to non-surgical periodontal treatment, on periodontal clinical and biochemical parameter i.e CRP. Materials and Methods: The study was designed as a randomized, controlled, single-blind, split-mouth clinical trial. Systemically healthy persons diagnosed with chronic periodontitis and presence of at least two bilateral maxillary premolars with ≥5-mm periodontal pocket depth were included in the study. The PPD, CAL,MGİ and SBI were measured at the baseline and at 1 and 3 months after periodontal treatment. Gingival crevicular fluid samples were taken at the baseline , 1 month and 3 months after treatment. The LLLT application was made in four sessions: after periodontal treatment, on the third day, and on the seventh day post-treatment. LLLT was applied in non-contact mode and tip tissue distance was approximately 1cm on every tooth on the test side for 15 s in the continuous mode, at 0.5 W and with an application tip 1 cm in diameter. Results: Intra group comparison for both the groups showed significant difference from baseline to one month for MGI and SBI and PD showed significant difference only in the test group , whereas from baseline to three months all the parameters showed statistically significant difference. Intergroup comparison between the groups showed statistically significant differences between MGI, SBI and CRP levels. Conclusion: Within the limitations of this study, LLLT in addition to non surgical periodontal treatment, has positive impact.
