Abstract
Purpose: The aim of the present in vitro study was to compare bacterial adhesion on four different implant abutment materials with diverse surface roughness.
Materials and Methods: The specimens of gold and zirconia were prepared and modified from the commercially available titanium rods (Ti) and TiN coating on machined titanium (TiN). Fusobacterium nucleatum, Porphyromonas gingivalis, and Treponema denticola in the saliva-coated specimens were analyzed by real-time polymerase chain reaction using the extracted DNA.
Results: F. nucleatum adhered well with an exception of gold. P. gingivalis adhered well to zirconia and T. denticola adhered more to zirconia, Ti than gold and TiN. In conclusion, bacterial adhesion in the saliva-coated specimens had less effect on surface roughness.
Conclusion: In stages of early adhesion, zirconia exhibited higher adhesion rate, but Ti coated TiN and gold materials show a low adhesion tendency.
