RESUMEN
OBJECTIVES: To assess the impact of oral health on the life quality of a periodontal patient group. MATERIALS AND METHODS: Two hundred and five patients attending a private periodontal clinic completed a questionnaire incorporating the 16-item UK oral health-related quality-of-life measure (OHQoL-UK), a check list of questions about their periodontal health over the past year and a comprehensive periodontal examination. RESULTS: The effect of oral health on quality of life was considerable, with many individuals experiencing negative impacts across a broad range of physical, social and psychological aspects of life quality. OHQoL-UK(Copyright ) scores was associated with patient's self-reported periodontal health in the past year: experiences of "swollen gums" (p<0.01), "sore gums" (p<0.01), "receding gums" (p<0.01), "loose teeth" (p<0.01), "drifting teeth" (p<0.01), "bad breath" (p<0.01) and "toothache" (p<0.01). In addition, OHQoL-UK scores were correlated with the number of teeth with pocket depths of 5 mm or more (r(s)-0.42, p<0.01). New patients had poorer oral health-related quality of life compared with the treated maintenance group (p<0.01). CONCLUSIONS: Periodontal status impacts on life quality. This has implications in understanding the consequences of periodontal health and in the use of patient-centred outcomes in periodontal research.
