Accessibility of Norwegian dental services according to family income from 1977 to 1989.
During the last 10-20 yr there has been a marked increase in demand for dental services in most western countries. An important issue is how this increase in demand has influenced inequalities in use of services among different income groups in the population. It is of particular interest to study this in Norway, as almost all the costs for dental care among adults are borne by the patient. The aim of the present study was to examine how the effect of family income on demand for dental services has changed over time. The analyses were performed on three sets of national data from 1977, 1983, and 1989. The samples were representative of the non-institutionalized Norwegian population aged 20 yr and above. Inequalities in use of dental services among different income groups have decreased between 1977 and 1989. However, separate analyses on the data from 1989 showed that some inequalities still exist. A non-selective subsidizing policy for dental care is unlikely to have any great effect in reducing these inequalities. Subsidized dental care is likely to raise the total amount of dental care demanded. However, it is difficult to assess accurately the size of this increase as the elasticity of demand for dental care in Norway with respect to price is unknown.
