Abstract

Two different types of fluorinated monomers were added to a conventional formulation for dental restorative material comprising a hydrocarbon-based methacrylic monomer and inorganic particulate fillers to afford fluorinated composites having sufficient strength and inertness. Fluorinated bisphenol-A dimethacrylate with ethylene glycols as the spacer between the core and methacryloyl groups, showed enough hydrophobicity and good compatibility with other components such as polyfluoroalkyl methacrylate, urethane methacrylate and silica particles, giving notable flexural strength, hardness, and anti-staining property to the composite. Without deteriorating the mechanical and anti-staining properties, the polyfluoroalkyl methacrylate compensated a high viscosity and a large refractive index of the aromatic fluoromonomer which reduced the amount of fillers to be loaded and the transparency of the composite. The fluorinated composite with fairly good mechanical properties, clarity, and antifouling character was found as the suitable material for artificial teeth with improved durability and esthetics.
