Significant differences between/among subgroups in CPI maximum score distribution and mean score ( ); Chi-square, Mann-Whitney, Kruskal Wallis, or Wilcoxon signed-rank tests as appropriate. Not significant. CPI codes—0: healthy; 1: bleeding on probing; 2: calculus detected on probing; 3: pocket depth 4-5 mm; 4: pocket depth 6 mm or more.
