[Abstract]:Background: fluorine in light-cured dental composites containing fluorine can reduce and prevent dental caries for a long time, but the preparation methods and properties of the materials are not reported. Objective: to study the preparation method and properties of photocurable fluorinated composite resin. Methods: the inorganic fillers (modified silica, hydroxyapatite or titanium dioxide) were mixed with catalyst triethylamine, bisphenol S, triethanol dimethacrylate, trifluoroacetic anhydride and different mass fractions of 51010 and 20%. The light cured fluorine composite resin was prepared. The tensile strength, flexural modulus, polymerization conversion and water absorption of the light cured fluorine composite resin were measured. The morphology of the composite resin was observed by transmission electron microscope (TEM). Results under the same mass fraction, the tensile strength of hydroxyapatite group was higher than that of silica group (P 0.05), the tensile strength of titanium dioxide group was significantly higher than that of silica group, and that of hydroxyapatite group was higher than that of silica group. There was no significant difference in flexural modulus between hydroxyapatite group and titanium dioxide group. The flexural modulus of silica group was significantly higher than that of hydroxyapatite group, and that of titanium dioxide group was higher than that of hydroxyapatite group. There was no significant difference in polymerization conversion between silica group and hydroxyapatite group. The polymerization conversion of titanium dioxide group was higher than that of silica group, and that of hydroxyapatite group was increasing with the increase of mass fraction of modified material. The transmission electron microscope showed that the fracture surface of silica group was relatively flat, the biocompatibility between resin body and filler was good, and the fracture surface of hydroxyapatite group was rough. The fracture surface of the titanium dioxide group is stratified, the filler is subsided in the resin body, and the titanium dioxide particles are deposited on the bottom of the resin, resulting in a large void and filler particles. The results showed that the photocurable fluorine-containing composite resin had good mechanical properties, curing properties and absorptivity.
