Twenty years experience with pit and fissure sealants

Twenty years of investigations on the use of pit and fissure sealants are presented with emphasis on application techniques, types of materials and long-term follow-up. After two decades of routine provision of pit and fissure sealants, we are able to conclude that placement of bonded resin sealant material is a highly effective approach for prevention of pit and fissure caries, provided the sealant material is correctly applied. © 2009 Nova Science Publishers, Inc.
