Abstract
Application of the pit and fissure sealant has been widely used as a caries preventive measure, particularly in pediatric dental practice. Two types of the sealant, Fluorosealant® and Clearseal-F®, the subjects in this study, have fluoride releasing ability and contain no Bis-GMA, while the conventionally used sealants contain Bis-GMA as the main component.
These sealants were applied to the pits and fissures diagnosed respectively as intact, CO or Cl, of 41 permanent molars in two groups of children who visited our Pediatric Dental Clinic, and were evaluated in regard to the retention rates as well as caries prevention rates of the sealants.
The retention rate of Fluorosealant® was 51.2% and that of Clearseal-F® was 87.8%, whereas no carious lesions were detected in the sealant applied molar teeth in both groups.
From these findings, it was considered that these materials were equally effective for caries prevention as well as disturbing the caries progress in pits and fissures of the permanent molars of children, although the retention rate was superior in case of Clearseal-F®.
