Population based norming of the UK oral health related quality of life measure (OHQoL-UK).
OBJECTIVE
The aims of this study were to establish normative age-gender values for the UK oral health related quality of life measure (OHQoL-UK) in Britain and to provide a local reference for its interpretation. In addition, to identify key factors associated with oral health related quality of life in the UK.


METHODS
A national survey conducted with the assistance of the Office for National Statistics involving a random probability sample of 2,718 households. Participants were interviewed about their oral health status. The impact of oral health on quality of life was measured using the 16 item OHQoL-UK measure.


RESULTS
The response rate was 68% (1,838/2,718). The majority (75%, 1,378/1,838) perceived their oral health as affecting their life quality and did so across a wide range of domains. Age-gender norm values are presented. Variations in OHQoL-UK scores were apparent in relation to socio-demographics: age (P<0.05), social class (P<0.01), and self-reported oral health status: number of teeth possessed (P<0.01).


CONCLUSIONS
The impact of oral health on the life quality of Britons was substantial, in both positive and negative ways and associated with socio-demographic and oral health (self-reported) factors. National norm values presented should provide a reference source for meaningful interpretation of similar data and local studies.
