Changes in oral health knowledge and behaviour 1987-95 among inhabitants of Wuhan City, PR China.

The purpose of this study was to evaluate the changes of oral health knowledge and behaviour among Wuhan citizens after six years of 'Love Teeth Day' campaigns. Representative samples of citizens aged 10-62 years were identified and interviewed in 1987 (n = 1180) and in 1995 (n = 1014). Data on oral health knowledge and practises were collected by structured questionnaires in both surveys and high response rates were obtained (87-94 per cent). In general, improvements in oral health knowledge and toothbrushing behaviour were observed in 1995 as compared with 1987. The younger age group (10-19-year-olds) showed significantly higher improvements of positive answers to knowledge items and toothbrushing behaviour. The findings also indicated that less than half of the interviewees were aware of the anti-caries effect of fluoride and about 30 per cent of the participants brushed their teeth performing the recommended method (vertical). In China, community based oral health education programmes should be implemented to further improve regular self-care practises, especially in relation to the adult population.
