The purpose of this paper was to describe the relationship between age, dental status, and patterns of dental visits. Data from a national health survey of 11,014 persons in Norway 1975 were used. The model shows that though the absolute number of regular attenders decreased with increasing age their relative number among dentate persons increased with increasing age. Different examples of how the model may be used are described. Finally three explanations are given of the dental attendance pattern among Norwegian adults.
