Purpose: With the observation of bacterial adhesion on the surface of the PFM and enamel, we analyzed the sequence of these adhesions and offer options for prevention of their occurrence.
Methods: The specimen made of PFM were polished step by step. Then they, along with the enamel were put into the liquid BHI culture medium containing Ua, Pg and An.

Article Synopsis
- This study investigates how the roughness of prosthesis surfaces affects the adhesion of common oral bacteria.
- Significant differences in bacterial adhesion were observed among various surface roughness levels, indicating that smoother surfaces may reduce bacteria attachment.
- The findings suggest using highly polished Co-Cr alloy prostheses to minimize bacterial adhesion and improve oral health outcomes.

Purpose: Mutans(Ua), porphynomonas(Pg),actinomyces Naeslundii(An) are the 3 bacteria that may cause the clonal formation, gingivitis and periodontitis. The aim of this study was to observe adhesion on the surface of the dental restorative materials and enamel, and to analyze the sequence of these adhesions and offer now the options for the prevention of their occurrence.
Methods: The specimen made of PFM and Co-Cr alloy were polished step by step.
