| [Objectives] The aim of the study was to investigate the process condition of sol-gel process of ZnO-related condition.The preparation parametes of nano Zinc Oxide was fused on the HAPw. Prepared with a rough surface HAPw/ZnO filler. Further research HAPw/ZnO composite fillers on the antibacterial properties of oral pathogens in order to prepare for the next lay the foundation for antibacterial filler.[Materials and Methods] Sol-gel process and ZnO, of different PH values, different dosage and different surface modification on the formation of nano ZnO cyclohexane particle size, dispersion and antibacterial properties; Preparation of nano-ZnO in determining the conditions, the nano-ZnO by a certain process-fused ceramic whiskers on the surface.Through TEM observation HAPw/ ZnO complex morphology of filler. Dilution test with four kinds of inorganic fillers (ZnO, HAPw/ ZnO, zinc oxide products, four needle-like zinc oxide whiskers) of oral cariogenic bacteria commonly have antibacterial properties.[Result] In the PH value of 8.2, Oleic acid content and the proportion of the total volume of alcoholic solution is 0.0015, the total amount of alcohol solution of cyclohexane 1/2 diameter of the nano ZnO, Nano-particle size is small, good dispersion.Under this condition ZnO colloid prepared as liquor, will be cleaned HAPw into the ZnO colloidal solution containing,40℃and 60% relative humidity for three days, Drying, calcinations, under the insulation in the whisker surface layer of ZnO colloidal crystals grown film. Antibacterial properties of zinc oxide that the Self,HAPw/ZnO, commodity zinc oxide, zinc oxide whiskers tetrapod all four antimicrobial agents have certain antibacterial properties.[Conclusions] Alcohol solution of zinc acetate in the sol-gel can be prepared under the conditions of small particle size zinc oxide nanoparticles. ZnO whiskers formed on the surface in a layer of ceramic membrane generated HAPw/ZnO has certain antibacterial properties.
