Evaluation of a Clinic‐based Sealant Program

Abstract

In 1984 a comprehensive sealant program was initiated for Guamanian children in grades one through eight. The goal of the program was to reduce caries rates in children on the fluoride-deficient island to a level at or below US mainland scores. At the initiation of the program, decayed, missing, and filled surfaces (DMFS) scores on Guam were approximately double those for US mainland children under 17 years of age. For the clinic-based preventive program, children in grades one through eight were bussed to one of two public health clinics for preventive services. These services included oral health education, toothbrushing instructions, and sealant application. Baseline and follow-up dental examinations (DMFS) were conducted in 1984 and 1986 on 1,061 and 987 children respectively, in grades one through eight to evaluate program impact. From 1984 to 1986, after the advent of a pit and fissure sealant program where over 15,000 children annually had sealants applied to their teeth, DMFS scores decreased 45 percent. The entire reduction in DMFS scores occurred on pitted and grooved surfaces and the effect reduced the DMFS by 2.4 surfaces/child in two years. The overall participation rate for both the elementary and middle schools was 80 percent and the first annual follow-up showed an overall sealant retention rate of 94 percent.
