Prevalence and oral health-related quality of life of self-reported orofacial conditions in Sweden

Abstract

Objectives

To (i) determine the prevalences of self-report in a Swedish adult population, of temporomandibular disorders, burning mouth syndrome, dry mouth, and bad breath and (ii) determine oral health-related quality of life impairment in subjects reporting these conditions.

Subjects and Methods

A cross-sectional, randomized sample of the adult Swedish population (response rate: 46%, N=1309 subjects) self-reported their condition from the preceding month to assess prevalences of self-report for the studied conditions together with comorbidity group of subjects who reported more than one condition. The 49-item Oral Health Impact Profile (OHIP) used to assess oral health-related quality of life.

Results

The most prevalent condition was bad breath (39%), followed by dry mouth (22%), temporomandibular disorders (18%), and burning mouth syndrome (4%). High comorbidity of conditions occurred in 27% of the population. Quality of life impairment increased with the number of comorbid conditions. Among individual conditions, burning mouth syndrome and temporomandibular disorders (57% and 40% OHIP points) presented higher impairment than dry mouth and bad breath (32% and 26% OHIP points).

Conclusions

Orofacial conditions were common and often coexist. The comorbidity group experienced the highest impact on oral health-related quality of life: the more comorbid conditions, the greater the negative impact.
