Objectives: To determine the oral health and treatment needs of the long-term hospitalised elderly., Setting: The Laakso long-term hospital, Helsinki, Finland., Design: A cross-sectional study with clinical oral examinations., Subjects: All long-term patients (n = 260) aged 60 and older., Main Outcome Measures: Edentulousness, presence and hygiene of dentures, mucosal findings, number of teeth, functioning teeth and tooth remnants, level of dental hygiene, and need for operative treatment., Results: Subjects' mean age was 83.3 years (SD = 8.1); 42% were edentulous, 45% of women and 33% of men (p = 0.12). With no gender difference, 41% had removable dentures, but one in four were considered to be in need of repair or replacement. Denture hygiene was good in 19%, moderate in 44%, and poor in 37%, and for men worse than for women (p = 0.02). Stomatitis was found in 25%, and angular cheilitis in 28% of the denture wearers. The dentate subjects had on average 12.4 (SD = 8.6) teeth with a clear difference by age (p = 0.03), but no difference by gender. Dental hygiene was considered poor. Of the dentate subjects, 37% were in need of restorations, 51% of periodontal therapy and 42% of extractions., Conclusions: Oral cleanliness should be improved with regards to dentures and teeth. More attention should be focused on dental care of the long-term hospitalised elderly.

Of a representative sample of 8000 persons aged 30 and over living in Finland, 3875 users of removable dentures were examined. The condition of the oral mucosa was recorded during clinical examinations. The prevalence of oral mucosal lesions associated with removable dentures was analyzed according to age, sex, place of residence, geographical region of living, and type and location of prosthesis. Lesions were found in about 50% of the denture wearers. Women were affected more often than men. The prevalence of lesions decreased with age and differed slightly according to region of living and place of residence. Compared with the wearing of partial dentures, wearing complete dentures increased the risk of lesions. Only one of the 72 denture users who wore a denture with metallic base plate had oral mucosal lesions associated with wearing a denture.
