  1. #Model 1: adjusted for sex, age, worked years and education level
  2. #Model 2: model 1+ mouthwash use, dental floss use, tooth brushing, mask use, smoking, drinking, and chewing areca
  3. #Model 3: model 2+ dietary habits with acidic foods
  4. #Univariate and multivariate logistic regression model were used
  5. *p < 0.05, **p < 0.01
