Title: Two-year clinical evaluation of a pit and fissure sealant. Part II: Caries initiation and progression
Abstract: The caries-protective efficacy of a pit and fissure sealant after two years of clinical service was studied. Pit and fissure sealant was 62% effective in stopping the initiation of occlusal caries at 12 months and 55% effective at 24 months. Caries protection was greater for premolars than for molars and was least for maxillary second molars. The caries-protective efficacy of a pit and fissure sealant was evaluated in relation to its clinical retention. After 24 months, 38% of all paired permanent control teeth judged caries free at the baseline examination were found to be carious, where as only 17% of thet reated teeth examined were carious. The corresponding relative reduction in caries rates was, there fore, 55%. The net gain, or number of teeth estimated to have been saved from caries by sealant application, was 83 teeth, or 21 teeth for every 100 treated. To determine what proportion of children received positive benefits from sealant application, the net gain per child was calculated. It was estimated that at least one tooth in 70% of the children was saved after 24 months. When the sealant remained completely intact, there was apronounced effect on caries initiation—the percent effectiveness being 91%. However, no appreciable gain or loss in caries protection was evident when the sealant was partially or completely missing.
