The antimicrobial effect of staphylococcus aureus, Streptococcus mutans, E. coli and Candida albicans are dependent on surface properties and restorative dental materials types. The aim of this study was to evaluate the effect of antibiotics on the residual natural saliva (after Filtek, glass-ionomer, porcelain and zirconia takeout from it). Also, the effect of brushing on fungi and bacteria growth in these surface materials was characterized. The results show that, bacterial growth around Filtek, glass ionomer, porcelain, and zirconia materials after takeout from saliva that is meant these materials have no resistance for E. coli, staphylococcus aureus, Streptococcus mutans and Candida albicans. The color of residual saliva changed. All antibiotics caused inhabitation zone except Ampicillin. Ciprofloxacin shows significant inhibition zone for all used materials. Also, brushing removed most if not all fungi and bacteria formed on surface dental materials.
