[Clinical aspects of root surface caries].

The present epidemiologic data indicate that root caries increases with age. Since the number of people in old age categories of population is increasing, root caries may be expected to become more and more common. This prediction is supported also by the anticipated increase in tooth longevity due to the declining caries prevalence in children and adolescents. Thus root caries is likely to become one of the problems in dentistry. Our present knowledge of root caries is insufficient and more research is needed into every aspect of the disease.
