Abstract: The purpose of this study was to clarify the properties of functional filler-containing pit and fissure sealants (FS). Seventy-two specimens were prepared and divided into three groups of three resin sealants ( S-PRG filler-containing FS, DELTON and Teethmate F1-2.0) and one glass-ionomer sealant (Fuji III LC). Each of six discs (6 mm in diameter ×3 mm in thickness) was used for 24-h, 4-week and 12-week experiments. Diametral tensile strength (DTS) and ion release were measured. S-PRG FS and Delton showed high values of DTS (23.2 MPa and 23.5 MPa, respectively) after 24 hours of storage. The DTS values of each sealant remained relatively constant. A large amount of fluoride was initially released from the sealants. However, fluoride release did not influence on DTS. S-PRG filler-containing FS released large amounts of strontium, boron and fluoride ions. Filler-containing sealants release large amounts of ions, contributing to antibacterial effects.
