Model 1: unadjusted
Model 2: adjusted for dental caries, sex, monthly family income, SOC, social support and dental pain
Model 3: model 2 + interaction term (dental caries × SOC, dental caries × social support and dental caries × dental pain)
*P < 0.05 and **P ≤ 0.001 are considered significant
^†Interaction was assessed through comparison likelihood ratio between models 2 and 3
