title: Health promoting schools and children's oral health related quality of life.
abstract: BACKGROUND
  The study objective was to compare children's oral health related quality of life (OHRQoL) in schools with 6 years of implementation of a health promoting school model in Malaysia, i.e. the Doktor Muda Programme (DMP) and in schools without the DMP.
  
  
  METHODS
  This report was part of a larger study to evaluate the DMP impact on schoolchildren's oral health knowledge, attitudes, behaviour, caries progression and OHRQoL. It was conducted in Negri Sembilan state. The sample comprised 3455, Year 6 (11-12 year old) children; 1282 from DMP (intervention) and 2173 from non-DMP (control) schools. The Malay Child-OIDP index was used to evaluate children's levels of oral impacts on 8 daily performances after 6 years of DMP implementation (2006-2011). Prevalence, score, impact intensity, causes and extent of impacts were compared. Chi-square and Mann-Whitney tests were used in the data analysis.
  
  
  RESULTS
  Overall response rate was 95.1%. Prevalence of overall impacts was 57.8% and 60.8% (mean total impact score was 7.10 and 7.77) in the intervention and control group, respectively. The three most frequently affected performances in both groups were eating, cleaning teeth and emotional stability. Significantly less DMP children had oral impact on cleaning teeth (p = 0.034). The majority of children with impacts in both groups reported 'very little' to 'moderate' levels of impact intensity. Significantly more DMP children reported having 'very little' and 'little' levels of impact intensity on cleaning teeth (p = 0.037) and emotional stability (p = 0.020), respectively. Significantly less DMP children reported having 'very severe' level of impact intensity on speaking (p = 0.038). The most prevalent cause of impacts in both groups was toothache. Significantly less DMP children reported bleeding gums (p = 0.016) and presence of plaque/calculus as causes of impacts (p = 0.032). About 75% of children with impacts in both groups reported having up to four daily performances affected.
  
  
  CONCLUSIONS
  This study showed that the health promoting school model, i.e. the Doktor Muda Programme for primary schools in Malaysia had some positive impacts on 11-12 year old children's oral health related quality of life.
