Indications for sealant use in a community-based preventive dentistry program

Dental caries is a disease that recently has undergone, and may still be undergoing, dramatic changes in distribution of incidence and prevalence. The most recent epidemiologic data available have been reviewed in this paper to illustrate that caries is becoming a disease primarily of pits and fissures, with less differentiation than previously acknowledged between fluoridated and fluoride-deficient areas. The present distribution of caries suggests that prevention may be accomplished more effectively through targeted sealant programs than through currently popular mass preventive programs. Existing information can be used to identify logical target groups for sealant programs, and age specific tooth eruption and caries attack information can be used to design delivery methods. Although the adoption of targeted sealant programs represents a departure from the traditional mass approach to prevention in dental programs, the present-day caries distribution requires that the initiation of such programs be given serious consideration. At the very least program administrators are encouraged to invoke the planning-implementation-evaluation process. Current programs should be evaluated carefully in view of today's disease patterns and the clinical significance of the results achieved. The content, design, and timing of future community-based programs should reflect individualized community diagnosis and the application of new epidemiologic data as well as a careful evaluation of the results achieved by current preventive procedures.
