The difference in the types of SLT used was statistically highly significant between males and females (X2 = 338.3; p < 0.001; Table 2 ). 3.3 Comparison of clinical parameters across the study groups There was a highly significant difference in probing pocket depth (PPD; t = 9.69; p < 0.001), gingival recession (GR; t = 16.16; p < 0.001), and clinical attachment loss (CAL; t = 13.73; p < 0.001) between the SLT users and NTB users ( Table 3 ). 3.4 Effect of tobacco placement on periodontal health The placement of tobacco at various sites within the oral cavity considerably influenced periodontal status ( p < 0.001 for all measurements; Table 4 ).
