Note: The analyses were adjusted for genotype (with CC as reference), ethnicity (with Caucasian as reference), dental floss daily (with use as reference), sweets between meals (with no ingest as reference), poor oral hygiene (with absence as reference). OR (95% C.I.)= Odds ratios; 95% confidence intervals. Bold forms indicated statistical significance; p≤0.10.

^# These variables were removed in multivariate analysis because when adjusted for other variables, the p-value was not significant.
