ECC was assessed according to WHO Oral Health Survey methods, and dmft (decayed, missing, and filled primary teeth) was calculated.

In adjusted models, higher sweet-food frequency was associated with greater odds of ECC (OR 1.72, 95% CI 1.19\u20132.49). Protective factors included vitamin D supplementation for \u22652 years (OR 0.40, 95% CI 0.18\u20130.86), bedtime toothbrushing (OR 0.22, 95% CI 0.13\u20130.38), use of fluoride toothpaste (OR 0.04, 95% CI 0.01\u20130.13), annual oral examinations (OR 0.26, 95% CI 0.15\u20130.44), and qualified parental oral-health knowledge (OR 0.38, 95% CI 0.23\u20130.65).
