BACKGROUND: Experimental and clinical experiences show that the surface roughness of dental restoration materials directly affects bacterial adhesion; in addition, the material composition and physicochemical properties are also important influencing factors. OBJECTIVE: To compare the bacterial adhesion of zirconia ceramics and nickel chromium al oy as oral materials. METHODS: Zirconia ceramics and nickel chromium al oy were respectively cut into 10 pieces of 3. 0 cm ×3.0 cm×0. 2 cm plate specimens. For each material, five pieces were subjected to surface polishing treatment, and the other five pieces were glazed. Surface roughness value of specimens was detected. Experimental strains of Streptococcus mutans was cultured on the specimen surface at 37 ℃ for 48 hours, and the amount of bacteria adhering to the specimen surface was detected. RESULTS AND CONCLUSION: Surface roughness of four groups of specimens showed no difference. The amount of bacteria that adhered to the polishing specimens of zirconia ceramics was significantly lower than that of nickel chromium al oy (P < 0.05), but no difference was found in the amount of bacteria adhering to the glazing specimens of nickel-chromium al oy and zirconia ceramics. These findings indicate that zirconia ceramics has better ability to inhibit bacterial adhesion than nickel-chromium al oy, especial y after glazing.
