Oral health status and related factors among primary school children in Soc Son district Hanoi city Vietnam
Abstract:
In Vietnam, oral health is a public health concern to health professionals, the
community and governments. Therefore the purpose of this study was to address the
oral health status and related factors among primary school children in the Soc son
district, Hanoi city, Vietnam. A cross sectional survey was conducted during January,
2008 among primary school children in the district. 228 school children in 3 primary
schools who had received the School- Based Dental Program (SBDP) over five years
were studied. Their oral health status was examined by a dentist using the WHO
recommended DMFT and CPITN index. Details of related factors were obtained by
self-administered questionnaire. Statistical descriptive analysis was used and tested by
Chi square and multivariable logistic regression was performed.
The prevalence of dental caries was 53.1 % and mean DMFT, 1.5. Forty three
per cent of the children studied had unhealthy gums. Seventy two per cent of the
children were brought by the parents or care-givers to see the dentist for a normal oral
check up. Only 24% of the children were highly knowledgeable about caries, but most
had a positive perception (59.6%) of oral health care. Most of the school children
(89.5%) brushed their teeth at least twice per day. There was a statistically significant
association between poorer education level of the parents or care-givers and better
DMFT index (p= 0.04) CPITN index (p = 0.01); between drinking sweetened drinks
and eating potato chips between meals with unhealthy CPITN index, p = 0.02 and
0.04, respectively. There was a significant association between those whose source of
information was either from magazines or from teachers with good oral health
students’ (DMFT index= 0) [p = 0.04 in both groups]. Importantly, poor oral health
status was best predicted by drinking sweetened drinks and CPITN index (β= 0.7,
OR=3.3, 95 %CI= 1.1 - 10.2, p= 0.03).
In conclusion, the SBDP is good, and should be expanded to allow preventive
dental services not only for fillings, but also for scaling. There should be a focus on
eating, brushing longer, and brushing in the morning.
