Tensile Bond Strength Between Fissure Sealants and Enamel

Abstract
Acrylic buttons were attached to tooth enamel by in situ curing of three types of polymeric fissure sealants, a dental cement, and a glass ionomer cement and then were immersed in water. The polymeric materials exhibited the greatest bond strengths to enamel, but in two instances the bond strength decreased with time although the cements showed increased strength. One polymeric material exhibited an unchanged bond strength.
