*The value of P is considered statistically significant. <0.05. AST – Aspartate aminotransferase; ALT – Alanine aminotransferase; CAL – Clinical attachment loss; DIS – Debris Index simplified; CIS – Calculus index simplified; BOP – Bleeding on probing; PD – Pocket depth; OR – Odds ratio; CI – Confidence interval; P – P-value or probability value
