Self-assessed dental health, oral health practices, and general health behaviors in Chinese urban adolescents.

The objectives of this study were: to describe perceived dental health status and oral health-related knowledge, attitudes, and behavior in Chinese urban adolescents; to assess the associations of oral health variables with socio-economic status and school performance; and to analyse the relative effect of socio-behavioral risk factors on perceived dental health, perceived need for dental care, and experience of dental symptoms. A cross-sectional survey of 2662 adolescents was conducted in eight capital cities in China; the response rate was 92%. The study population was chosen by multistage cluster sampling and covered three age groups: 11, 13, and 15 years. Data on dental and general health were collected by self-administered questionnaires. Self-assessment of dental health of Chinese adolescents was generally good, only 12% of the students answered that their teeth were "poor" or "very poor", and 9% claimed having "poor" or "very poor" gums. Eleven percent of participants said that other students made fun of their teeth; 24% of the respondents were dissatisfied with the appearance of their teeth, and 41% claimed that they had experienced toothache or symptoms during the previous 12 months. Positive attitudes towards dental care were found in all age groups; 67% of adolescents brushed their teeth at least twice a day and 48% of the students used fluoridated toothpaste. Only 26% of the students visited a dentist during the previous 12 months. In all, 6% of the adolescents had tried cigarette smoking at least once, while 41% reported having tasted alcohol drinks. Multivariate regression analyses showed that perceived dental health status and needs were associated with gender, age, unhealthy lifestyles, poor school performance, and socio-economic status. The establishment of school-based health promotion programs in China is urgently needed, and promotion of oral health lifestyles should be integrated with other general health actions.

Exploratory thoughts concerning educational reform with problem-based learning in China.

The author, a novice problem-based learning (PBL) advocate in China and a young faculty member of the School of Stomatology at Wuhan University, joined a PBL tutorial group as an observer during his two-month visit at McMaster University. He describes his observations and thoughts as they relate to the current reform of health sciences education in China.

Can school-based oral health education and a sugar-free chewing gum program improve oral health? Results from a two-year study in PR China.

The purpose of the study was to assess the outcome of school-based oral health education (OHE) and a sugar-free chewing gum program on the oral health status of children in terms of reduced caries increment and gingival bleeding over a period of 2 years. Nine primary schools randomly chosen from one district were divided into three groups: OHE group (Group E), sugar-free chewing gum in addition to OHE group (Group G), and the control group (Group C). All children of grade 1 (aged 6-7 years) were recruited (n = 1342). After 2 years, 1143 children remained in the study group at follow-up. The overall drop-out rate was about 15%. Data on dental caries and gingival bleeding were collected by clinical examination. The results showed that the mean increment of DMFS in Group G was 42% lower than in groups E and C (P < 0.05). The mean increments in F-S were higher in Groups G and E than in Group C (P < 0.01). The gingival bleeding scores were statistically significant among the three groups. Compared to Group C, the mean increment in bleeding scores of Group G was 71% lower (P < 0.01) and in Group E 42% lower (P < 0.05). The school-based OHE programs had some positive effect improving children's oral hygiene; in certain circumstances children may benefit from using polyol-containing chewing gum in terms of reduced dental caries.

Effect of a school-based oral health education programme in Wuhan City, Peoples Republic of China.

OBJECTIVES: To assess oral health outcomes of a school-based oral health education (OHE) programme on children, mothers and schoolteachers in China, and to evaluate the methods applied and materials used. DESIGN: The WHO Health Promoting Schools Project applied to primary schoolchildren in 3 experimental and 3 control schools in Hongshan District, Wuhan City, Central China, with a 3-year follow-up. Data on dental caries, gingival bleeding and behaviour were collected. PARTICIPANTS: 803 children and their mothers, and 369 teachers were included at baseline in 1998. After three years, 666 children and their mothers (response rate 83%), and 347 teachers (response rate 94%) remained. RESULTS: DMFT/DMFS increments were comparable but the f/F components were higher among children in experimental schools than in control schools and the gingival bleeding score was, similarly, significantly lower. More children in experimental schools adopted regular oral health behaviour such as toothbrushing, recent dental visits, use of fluoride toothpaste, with less frequent consumption of cakes/biscuits compared to controls. In experimental schools, mothers showed significant beneficial oral health developments, while teachers showed higher oral health knowledge and more positive attitudes, also being satisfied with training workshops, methods applied, materials used and involvement with children in OHE. CONCLUSIONS: The programme had positive effects on gingival bleeding score and oral health behaviour of children, and on oral health knowledge and attitudes of mothers and teachers. No positive effect on dental caries incidence rate was demonstrated by the OHE programme.

[A survey on dental knowledge and behavior of mothers and teachers of school children].

OBJECTIVE: The purpose of this survey was to assess dental knowledge and behaviors of the teachers and mothers of school children. METHODS: All data was collected from 1365 mothers of first grade students and 215 schoolteachers in Yichang, Hubei by using questionnaires and, analyzed using SPSS software. RESULTS: The level of dental knowledge was higher among schoolteachers than among mothers; the mothers were mostly informed through television/book (62.4%/51.5%), while teachers received information from various sources, including the dentists (75.3%). Most of the children (94.0%) didn't have practical support from their parents in daily tooth cleaning. Only 18.9% of them visited the dentist at least once per year. CONCLUSION: This finding suggested that we should emphasize oral healthy education among mothers and schoolteachers, in order to promote school-based oral health education program.
