title: Oral health and oral health behaviour among 11-13-year-olds in Bhopal, India.
abstract: OBJECTIVE
  To assess the prevalence of dental caries, to describe the periodontal conditions, and to assess the level of attitude, knowledge and practice in relation to oral health and oral health behaviour among 11-13 year-old children in Bhopal, India. The data would aim to provide a baseline for planning and evaluation of oral health education programmes for children in the region. BASIC RESEARCH DESIGN AND OUTCOME MEASURES: A cross sectional study of 599 children 11-13 years was conducted. Random sampling procedures were used to obtain representative samples of children in rural (n = 181) and urban areas (n = 277). In urban slum areas convenience sampling was applied (n = 141). The data were collected through clinical examinations by means of WHO standard method, and a sub-sample completed a self-administered questionnaire on oral health behaviour, knowledge, and attitude.
  
  
  RESULTS
  The caries prevalence proportion in both dentitions was 57% with a mean DMFT+dmft of 1.6. The caries experience was 2.5 times higher among children in slum areas compared to children living in rural areas. Fifteen per cent of the children had healthy gingiva and 91% of rural children had maximum CPI score 2. Mean number of sextants with CPI score 0 was 3.5 among children in urban areas and 0.6 for children in slum areas. Seventy-five per cent of the children reported toothbrushing once a day, 31% used a plastic toothbrush and the general level of knowledge on oral health was low. Intake of sugary food and soft drinks were more frequent in the slum areas compared to rural areas.
  
  
  CONCLUSIONS
  Implementation of community-oriented oral health promotion programmes is needed in order to increase the level of knowledge and to change attitudes and practices in relation to oral health among children. Essential care should be provided to control oral disease symptoms.
