Abstract
Objective. The aim was to assess the prevalence and background factors of signs of infection of dental origin in elderly Finns. Materials and methods. Every third birth cohort between 60-78 years of age (n = 1733) in a southern and a northern region in Finland were invited. Altogether, 1069 subjects attended radiographic examination. Of those, 660 were dentate and formed the study sample. In the analysis an index as a sum of points (scale per lesion 0-3, range 0-420) indicating the severity of infection from periapical lesions, furcal lesions, vertical bone pockets, horizontal bone loss and severe dental caries was used. Results. The index ranged individually from 0-91. Horizontal bone loss was found in 94%, vertical bone loss in 19%, periapical lesions in 46%, furcal lesions in 19% and carious lesions in 39% of the subjects. Only 3% of the subjects were free of dental infections, while 2% had mild, 17% moderate and 78% severe risk of dentogenic infection. Statistically significant background factors were region, level of education, number of regular drugs in use, drugs reducing salivation, alcohol consumption, cardiovascular disease, asthma and rheumatoid arthritis. Conclusions. Elderly Finns have high a prevalence of signs of infections of dental origin, which is associated with several socio-demographic and health-related factors.
