Oral health in Asia

Dental caries and associated factors in 12-year-old schoolchildren in Thiruvananthapuram, Kerala, India

OBJECTIVES

The aims of the present study were to describe the dental health status of 12-year-old schoolchildren in Thiruvananthapuram, Kerala, India, and to identify sociodemographic factors, oral health behaviours, attitudes and knowledge related to dental caries experience.

METHODS

The study took the form of a cross-sectional survey of 838 children in upper primary schools. A two-stage cluster sampling technique was used. Dental caries was measured using World Health Organization criteria. Sociodemographic factors, oral health behaviours, attitudes and knowledge were assessed by a self-administered questionnaire.

RESULTS

The prevalence of dental caries in the permanent dentition was 27%. The mean number of decayed, missing and filled teeth was 0.5 (SD=0.9). The decayed component (D) constituted 91% of the total number of decayed, missing and filled teeth (DMFT). Multiple logistic regression analysis showed that children had a higher risk of having dental caries if they lived in urban area [OR=1.5, 95% confidence interval (CI)=1.1-2.1], had visited a dentist (OR=1.6, 95% CI=1.2-2.2), did not use a toothbrush (OR=1.9, 95% CI=1.2-2.9), consumed sweets (OR=1.4, 95% CI=1.0-1.9) or performed poorly in school (OR=1.7, 95% CI=1.0-2.3).

CONCLUSIONS

The prevalence of caries in this sample of 12-year-old schoolchildren was low compared to that in other developing countries. The present study indicated that urban living conditions were associated with more dental caries. Since urbanization is rapid in India, oral health promotion at the present time would be valuable to prevent increased caries prevalence.

Dental service use and the implications for oral cancer screening in a sample of Bangladeshi adult medical care users living in Tower Hamlets, UK

AIM

To assess the use of dental services, barriers to uptake of dental care and attitudes to regular dental examinations and the prevalence of tobacco and paan chewing habits in a group of Bangladeshi medical care users.

DESIGN

Multi-centre cross-sectional study.

SETTING

Four general medical practices' waiting areas in Tower Hamlets.

SUBJECTS

Bangladeshi adults aged 40 years and over.

INTERVENTION

An interview schedule.

MAIN OUTCOME MEASURES

The prevalence of tobacco smoking and paan chewing with or without the addition of tobacco. The use of dental services, barriers to the use of dental services and attitudes to regular dental examinations.

RESULTS

Results were obtained from 158 subjects (response rate 85%). 25% of the whole sample had never visited a dentist. These were significantly (P < 0.05) more likely to be women, who also thought regular check-ups were of little value. In their use of health services 73% experienced language difficulties. 33% of the sample were tobacco smokers. Paan was chewed by 78% of the sample with significantly (P < 0.05) more females than males adding tobacco to their quid and chewing more frequently than males.

CONCLUSION

There are considerable barriers to be overcome if dental practices are to be the site for oral cancer screening and oral health promotion in this population. There are sex differences in reported behaviour and attitudes about use of dental services and in tobacco and paan use in this Bangladeshi sample. Further research is needed to establish why this ethnic minority attend general medical practices but not general dental practices.
