Association of oral health knowledge, self-efficacy and behaviours with oral health-related quality of life in Chinese primary school children: a cross-sectional study.

This study revealed a pathway of association between children's oral health knowledge and their OHRQOL, in which children's oral health self-efficacy and behaviours had indirect effects. This provides a basis for understanding the mechanism of oral health promotion interventions to improve children's OHRQOL and helps to identify direct or indirect intervention targets.
