摘要

Objective: Pit and fissure sealants have the ability to release fluoride into the oral environment and reuptake fluoride from the fluoridated products. Therefore, the purpose of this study was to investigate the fluoride release and the rechargibilty potential of different fissure sealants after exposure to various fluoride preventive treatments with different fluoride concentrations.;Materials and Methods: Sixty caries free, extracted teeth were sealed with four types of sealants: Helioseal, Ultraseal XT plus, Fuji II LC, and Fuji Triage. The teeth were stored in test tubes containing 5ml artificial saliva, and the fluoride release was measured daily on the first week, on day 21, and after 28 days using a fluoride specific electrode. On day 29, the fissure sealants were divided into three subgroups, and then subjected to three different fluoride treatments (APF gel, APFgel-Colgate toothpaste, and Prevident toothpaste). The fluoride release was measured daily in the first week, and then weekly for two weeks.;Results: The glass ionomer sealant (Fuji Triage) released significantly more fluoride than the other tested sealants (p<0.0001). After the fluoride treatments, all fissure sealants showed high fluoride release, but significantly more with APF gel and APFgel-Colgate tooth paste (p<0.0001).;Conclusions: The glass ionomer based sealant (Fuji Triage) released significantly more fluoride than the other tested fissure sealants (resin modified glass ionomer, resin sealants). The use of APF gel and APFgel-regular toothpaste (Colgate) treatments significantly recharged the sealants more than highly fluoridated toothpaste (Prevident). The high fluoride toothpaste ( Prevident) provided significantly more fluoride only for glass ionmer sealants (Fuji Triage) and resin modified glass ionomer sealants (Fuji II LC).
