OBJECTIVE: To assess the oral hygiene practices, current use of and knowledge about fluoride toothpaste among schoolchildren, parents, and schoolteachers; to describe the attitudes of parents and schoolteachers in relation to improving schoolchildren's oral health.

DESIGN: Cross-sectional study.

PARTICIPANTS: 1,557 schoolchildren, 1,132 parents, and 352 schoolteachers were recruited by multistage stratified sampling procedure in a district of Beijing, China.

METHODS: Self-completed questionnaire.

RESULTS: The percentage of schoolchildren, parents, and schoolteachers who actually used fluoride toothpaste was 88%, 86%, and 87%, respectively, and 74-78% of the respondent groups brushed their teeth twice a day or more. 64% of schoolchildren, 73% of parents, and 74% of schoolteachers confirmed the caries preventive effect of fluoride toothpaste. Toothpaste recommended by oral health professional organisations was preferred by respondents - particularly by schoolchildren - when purchasing toothpaste (86%). 93% of parents and 56% of schoolteachers recognised their important role in promoting children's oral health; however, their lack of knowledge seemed to be a major obstacle in fulfilling this role.

CONCLUSIONS: The use of fluoride toothpaste in Beijing appears to have increased during the past decade. In addition to mass communication comprehensive school-based oral health programmes are needed to continuously promote the use of fluoride toothpaste among schoolchildren.
