A cross-sectional study of oral health and oral health-related quality of life among frail elderly persons on admission to a special oral health care programme in Copenhagen City, Denmark.

AIM To describe the oral health and the oral-health-related quality of life (OHRQoL) of citizens in Copenhagen City on admission to a specific oral health-care programme for disabled elderly persons. Further, to analyse how various factors influence the oral health and the OHRQoL among these patients. METHODS A cross-sectional study of 189 persons (average 85 years) consecutively admitted to a special oral health-care programme. Clinical data and data from interviews comprising social factors, life-style, dental visit habits, oral hygiene practices and self-perceived oral health were collected. A modified index on perceived dysfunction, discomfort and disability due to oral disorders was used. RESULTS Sixty-eight per cent had natural teeth, among those 57% had decayed teeth and two out of three wore dentures. Smoking habits influence the number of teeth present and the OHRQoL (p < 0.05) of the patients. Edentulousness, decayed teeth, and presence of dentures did not seem to cause OHRQoL problems, while higher OHRQoL scores (more problems) were reported by those with 1-9 teeth and tooth mobility. CONCLUSION OHRQoL of these patients can be increased by removal of loose teeth and provision of dentures to those with very few teeth rather than focus on traditional caries treatment.
