*Value of P is considered statistically significant P<0.05. P>0.05 statistically NS. SD – Standard deviation; ANOVA – Analysis of variance; F – Fisher in ANOVA test; P – Probability; NS – Nonsignificant. PI – Plaque index; BI – Bleeding index; PD – Probing depth; CAL – Clinical attachment level; T2DM – Type 2 diabetes mellitus; A1 – Periodontitis participants receiving scaling and root planing alone; A2 – Periodontitis participants receiving scaling and root planing with adjunctive low-level laser therapy; B1 – Periodontitis participants with T2DM receiving scaling and root planing alone; B2 – Periodontitis participants with T2DM receiving scaling and root planing with adjunctive low level-laser therapy
