Oral health-related quality of life and its relationship to self-reported oral discomfort and clinical status.

Abstract

The impact of oral health on quality of life is one aspect when it comes to understanding the significance of oral health. The aim of this study was to analyse the self-reported oral discomfort and clinical status of individuals reporting oral problems never/very seldom affecting quality of life during the last year and compare them with individuals who reported oral problems hardly ever/occasionally or often/very often during the the same period. The study comprised a stratified random sample of 515 individuals who lived in four parishes in the City of Jonköping, Sweden, and turned 20, 30, 40, 50, 60, 70 and 80 years of age in 2003. The impact of oral health on quality of life was examined using the OHIP-14 questionnaire. The individuals were also examined clinically and radiographically. Of the participants, 21% reported no experience of impaired quality of life and 20% of the individuals reported that they had experienced impaired quality of life often or very often during the last year. The highest frequency of oral problems was found among individuals aged 20 and 80 years. Subjective symptoms, such as grinding/clenching and headache, were found among 20- and 30-year-olds. Edentulous individuals and individuals with many missing teeth, individuals with severe periodontal disease or subjective dry mouth answered that they experienced problems according to the OHIP-14 often or very often. A number of individuals, young and old, had thus experienced subjective or clinically verified oral conditions associated with a negative experience of quality of life. This complementary information will provide a deeper understanding of the importance of oral health in the population.
