This study was carried out to assess the associations between oral diseases and specifically oral health-related quality of life (OHRQoL) in a nationally representative sample of 12-year-old children in Thailand in order to classify children according to their levels of risk for adverse OHRQoL and to apply findings to formulate proposals for oral health goals. Oral examinations and OHRQoL interviews using the Child-Oral Impacts on Daily Performances (Child-OIDP) schedule were conducted in 1,100 children as part of the Thailand National Oral Health Survey. The severity of oral impacts was categorised according to their 'intensity'. Associations of oral diseases and condition-specific (CS) OHRQoL impacts were investigated. Oral impacts were prevalent. Most were of low intensity; these were excluded from the analysis used to develop goals. At the threshold of moderate/high intensity, CS impacts attributable to dental caries, edentulous areas, periodontal disease and discolouration were reported by 18.5%, 0.2%, 8.7% and 2.6% of participants, respectively. Missing teeth was significantly related to CS impacts. Condition-specific impacts were 1.6 times and three to four times more likely to affect children with one decayed tooth and two or more decayed teeth, respectively. Children with gingivitis or calculus in three or more sextants were twice as likely and children with calculus and gingivitis in three or more sextants were 3.5 times more likely to report CS impacts. Based on these findings, these recommendations are proposed: all 12-year-old children should have fewer than two untreated decayed teeth; 60% of 12-year-old children should not have periodontal disease in any form in more than two sextants, and the proportion of 12-year-old children with calculus with gingivitis in three or more sextants should not exceed 5%. Measures of oral health and goals for oral health in children should include measures of OHRQoL.


    • "Adolescents who presented with bleeding gums after tooth brushing were four times more likely to report an impact on their daily lives than those without gingival bleeding [15]. Other studies considering a variety of forms of extension of gingivitis [gingival bleeding on probing, normative treatment needs, sextants], recorded by CPI, found worse OHRQoL in a wide age-range of population [children, adolescents and the elderly12131416171819. These results suggest that the OHRQoL measure is sensitive to gingival health, irrespective of whether it is self-reported or clinically observed [28]. "

  • [Show abstract] [Hide abstract] ABSTRACT: Dental caries is generally given the highest priority in national oral health services for school-aged populations. Yet, there is no study exploring the impacts on quality of life specifically related to dental caries in national samples of school-aged children. This study assessed prevalence and characteristics of oral impacts attributed to dental caries on quality of life and compared them with overall oral health impacts. In addition, associations of oral impacts attributed to dental caries and dental caries status were investigated. A national representative sample of 1,063 12- and 811 15-year-olds completed a sociodemographic and behavioural questionnaire, and were orally examined and interviewed about oral health-related quality of life using the Child-OIDP or OIDP indexes, respectively. Associations of condition-specific impacts (CS impacts) attributed to dental caries with components of DMF were investigated using χ(2) tests and multivariate logistic regressions. CS impacts attributed to dental caries were reported by nearly half the children and such impacts accounted for half of overall oral impacts from all oral conditions. The majority of impacts were of little intensity and affected only 1-2 daily performances, particularly performances on Eating, Emotional stability and Cleaning teeth. CS impacts were significantly positively associated with number of decayed teeth, and strongly associated with severe decay.

  • [Show abstract] [Hide abstract] ABSTRACT: To assess the associations of global subjective ratings of oral health with different aspects of an oral health-related quality of life measure, namely total Oral Impacts on Daily Performances (OIDP) and Child-Oral Impacts on Daily Performances (Child-OIDP) scores, extent and intensity of oral impacts, the different performance scores and oral impacts attributed to certain groups of oral conditions. This study was part of the Sixth Thailand National Oral Health Survey. One thousand and sixty-six 12-year-olds and 815 15-year-olds were interviewed on their OHRQoL using Child-OIDP and OIDP indices, respectively, and rated their overall oral problems on 3-point and 5-point scales, respectively. Associations of global rating of oral health with different Child-OIDP/OIDP outcome variables were estimated using Spearman's rank correlations and logistic regressions. Child-OIDP/OIDP scores were significantly associated with global ratings. Intensity was associated with global ratings, whereas extent was not. Impacts of 'very little' intensity were associated with a slightly higher chance of having poorer oral health perceptions. Global ratings were associated most with oral impacts attributed to dental caries, but not with the impacts related to natural process, such as eruption. Eating, cleaning teeth, emotional stability and smiling, plus social contact in 15-year-olds were performances associated with global ratings. Fifteen-year-old girls were more likely to perceive more oral problems than boys. Associations of global ratings of oral health with Child-OIDP/OIDP scores were mainly due to the intensity of impacts. Global ratings were related to multidimensional aspects of children's quality of life.
