While the use of adult oral-health-related quality-of-life (OHRQoL) measures in supplementing clinical indicators has increased, that for children has lagged behind, because of the difficulties of developing and validating such measures for children. This study examined the construct validity of the Child Perceptions Questionnaire (CPQ(11-14)) in a random sample of 12- and 13-year-old New Zealanders. It was hypothesized that children with more severe malocclusions or greater caries experience would have higher overall (and subscale domain) CPQ(11-14) scores. Children (N = 430) completed the CPQ(11-14) and were examined for malocclusion (Dental Aesthetic Index) and dental caries. There was a distinct gradient in mean CPQ(11-14) scores by malocclusion severity, but there were differences across the four subscales. Children in the worst 25% of the DMFS distribution had higher CPQ(11-14) scores overall and for each of the 4 subscales. The construct validity of the CPQ(11-14) appears to be acceptable.

    • "On the other hand, children's responses may be influenced by other things, such as their physical or emotional state, social norms, or behavior (Jocovic et al., 2005). The convergent validity varied across studies conducted in different languages, which suggests that there might be some cultural differences as well (Jocovic et al., 2002; Foster Page et al., 2005; Marshman et al., 2005; Brown and Al-Khayal, 2006; Broder and Wilson-Genderson, 2007; McGrath et al., 2008). An observed association between oral health and the CPQ total scale and two subscales in the second survey may reflect that the children have become cognitively more aware about the concept of health and oral health or that they started to pay more attention to their oral health and its impacts on their lives after the first survey.

    ABSTRACT: Objective: The aim was to compare the oral health-related quality of life among 11- to 14-year-old patients with cleft lip and/or palate (CLP) and schoolchildren without CLP. The validity and reliability of the Finnish Child Perception Questionnaire designed for 11- to 14-year-olds (CPQ11-14) was also assessed. Design and subjects: Participants in this cross-sectional questionnaire survey study were children aged 11 to 14 years from two groups. The CLP sample included all children of this age who had had CLP selected from the regional treatment register (N = 51). The school sample included children from four school classes (N = 82). Informed consent from parents was obtained. Ethical clearance and parental informed consent were obtained. Main outcome measures: Oral health-related quality of life was measured with the CPQ11-14. Results: The CPQ11-14 total and functional limitations, emotional well-being, and social well-being subscores were poorer among patients with CLP than among schoolchildren without CLP (mean scores: 55.5 versus 15.0; 11.9 versus 5.1; 14.0 versus 2.8; 12.6 versus 4.2; and 17.1 versus 2.9, respectively; all P < .001 for Mann-Whitney tests). Cronbach alpha value was 0.97 for total scale and between 0.81 and 0.94 for subscales. Among all children in the school sample, intraclass correlation coefficient was 0.79 for total scale and varied between 0.65 and 0.74 for subscales. Conclusion: The oral health-related quality of life of Finnish children with CLP was considerably poorer than that of their peers in overall and all dimensions, especially social well-being. The CPQ11-14 showed appropriate reliability and validity.

    • ". Children with active dental caries are more likely to experience oral pain, have difficulty chewing, be worried or upset about their mouths or miss school due to their cumulative disease experience [Foster Page et al., 2005]. Dental interventions in children with ECC have a significant positive impact on parental ratings of their oral health. "

    ABSTRACT: Child oral health-related quality of life (COHRQoL) has been assessed in developed areas; however, it remains unstudied in mainland China. Studies on COHRQoL would benefit a large number of children in China suffering from oral health problems such as dental caries. This study explored the relationship between COHRQoL and early childhood caries, adjusted by socioeconomic factors, in 3- to 4-year-old children in a region of southern China. In this study, 1062 children aged 3-4 years were recruited by cluster sampling and their oral health statuses were examined by a trained dentist. The Chinese version of the Early Childhood Oral Health Impact Scale (ECOHIS) and questions about the children's socioeconomic conditions were completed by the children's parents. A negative binomial regression analysis was used to assess the prevalence of early childhood caries among the children and its influence on COHRQoL. The total ECOHIS scores of the returned scale sets ranged from 0 to 31, and their average scores was 3.1±5.1. The negative binomial analysis showed that the dmfs indices were significantly associated with the ECOHIS score and subscale scores (P<0.05). The multivariate adjusted model showed that a higher dmft index was associated with greater negative impact on COHRQoL (RR = 1.10; 95% CI = 1.07, 1.13; P < 0.05). However, demographic and socioeconomic factors were not associated with COHRQoL (P>0.05). The severity of early childhood caries has a negative impact on the oral health-related quality of life of preschool children and their parents.

    • "Oral health is an integral component of overall health and wellbeing. Dental caries among children is a chronic condition that not only causes pain, but impacts on a child’s ability to function (Sheiham [6], Gaynor and Thomson [7], Foster Page et al. [8]). ECC is defined as the presence of one or more decayed, missing or filled teeth (dmft, the index for caries severity) in the primary dentition in a child younger than six years. "

    ABSTRACT: Maaori are the Indigenous people of New Zealand and do not enjoy the same oral health status as the non-Indigenous majority. To overcome oral health disparities, the life course approach affords a valid foundation on which to develop a process that will contribute to the protection of the oral health of young infants. The key to this process is the support that could be provided to the parents or care givers of Maaori infants during the pregnancy of the mother and the early years of the child. This study seeks to determine whether implementing a kaupapa Maaori (Maaori philosophical viewpoint) in an early childhood caries (ECC) intervention reduces dental disease burden among Maaori children. The intervention consists of four approaches to prevent early childhood caries: dental care provided during pregnancy, fluoride varnish application to the teeth of children, motivational interviewing, and anticipatory guidance.Methods/design: The participants are Maaori women who are expecting a child and who reside within the Maaori tribal area of Waikato-Tainui.This randomised-control trial will be undertaken utilising the principles of kaupapa Maaori research, which encompasses Maaori leadership, Maaori relationships, Maaori customary practices, etiquette and protocol. Participants will be monitored through clinical and self-reported information collected throughout the ECC intervention. Self-report information will be collected in a baseline questionnaire during pregnancy and when children are aged 24 and 36 months. Clinical oral health data will be collected during standardised examinations at ages 24 and 36 months by calibrated dental professionals. All participants receive the ECC intervention benefits, with the intervention delayed by 24 months for participants who are randomised to the control-delayed arm. The development and evaluation of oral health interventions may produce evidence that supports the application of the principles of kaupapa Maaori research in the research processes. This study will assess an ECC intervention which could provide a meaningful approach for Maaori for the protection and maintenance of oral health for Maaori children and their family, thus reducing oral health disparities.Trial registration: Australia and New Zealand Clinical Trials Register (ANZCTR): ACTRN12611000111976.
