The invention relates to a photo-cured dental pit and fissure sealant composition for caries prevention: i) based on the multifunctional prepolymer mixture of 2,2-bis-(4-(2-hydroxy-3-methacryloyloxypropoxy)phenyl)propane (&ldquo;Bis-GMA&rdquo;), which has conventionally been used as dental pit and fissure sealant for caries prevention, and a multifunctional prepolymer formed by substituting hydrogen atoms in hydroxyl group with methacrylate groups in the Bis-GMA molecules; and ii) comprising a diluent, an inorganic filler, a photoinitiation system, and other additives. The dental pit and fissure sealant composition of the present invention is based on a multifunctional prepolymer mixture and has better physical and mechanical properties and biocompatibility than a conventional composition based on Bis-GMA only.
