Table 2.
Clinical data of the study population. Pocket depth (PD), clinical attachment loss (CAL), bleeding on probing (BOP), plaque index (PI), number of teeth excluding 3rd molars, number of decayed, missing, filled teeth (DMFT). All parameters tested were checked for normality. Metadata of the clinical data of the study population, which followed a Gaussian distribution were compared using t-test, chi-square test and ANOVA, whereas non-parametric data were compared by Mann-Whitney U test, Friedman test and Kruskall-Wallis H test. All statistics were computed with GraphPad Prism (Graphpad Software, San Diego, CA).
