Abbreviation: 95%CI, 95% confidence interval; CAL, clinical attachment loss; CI, calculus index; DFRoot, decayed and filled root; DMFT, decayed, missing and filled teeth; DT, decayed teeth; exp(coef), exponential coefficient; FT, filled teeth; GBI, gingival bleeding index; MT, missing teeth; PD, probing depth
  2. Model 1 was adjusted for age, sex, and years of education. Model 2 was further adjusted for toothbrushing frequency, smoking, alcohol consumption, hypertension, diabetes, and hyperlipidemia
