Context: Tumor necrosis factor-alpha (TNF-α) has been shown to play a critical role in the pathogenesis of periodontitis and diabetes. Nonsurgical periodontal therapy was shown to reduce inflammation and improves glycemic status. Recently, adjunctive low level laser therapy (LLLT) has been shown to alter the inflammatory process. Aim: To evaluate and compare the alteration in TNF-α levels before and after treatment in patients with periodontitis with and without type 2 diabetes mellitus (T2DM). Settings and Design: Randomised clinico-biochemical study was carried out for 8 weeks from September 2019 to December 2020. Materials and Methods: Sixty-four participants were divided into Groups A (periodontitis) and B (periodontitis associated with T2DM), based on probing depth ≥5 mm, clinical attachment level ≥2 mm, and history of T2DM. Later were subdivided into A1, A2, B1, B2, based on assigned treatments. Clinical periodontal parameters and salivary TNF-α levels were evaluated and compared at baseline to 8 weeks. Statistical Analysis: Multiple group comparisons were done using analysis of variance, intra group comparisons were made using t-tests. Results: Comparison of periodontal parameters and salivary TNF-α levels from baseline to 8 weeks showed statistically significant difference (P < 0.05) in all groups, indicating a positive effect of scaling and root planing (SRP) and adjunctive LLLT. Conclusion: Both SRP and SRP with adjunctive LLLT effectively altered TNF-α levels, correlating reduced periodontal inflammation.
