Comparison of microleakage between flowable nanocomposite, flowable Composite and Conventional sealant in fissure sealant therapy of the permanent teeth: an in- vitro study

ABSTRACT

Background and Aim: Novel dental materials including nanocomposites have been introduced in recent years. It is claimed that they have superior properties such as high esthetic, low wear, increased filler content resulting in better mechanical properties, and releasing ions i.e. fluoride and amorphous calcium phosphate that are important for enamel remineralization. Considering these features, if they have retention and microleakage rates comparable with conventional sealants, these materials can be appropriate alternatives to conventional resin sealants in future
