Electrochemical Investigation of Interaction of Candida albicans with Titanium-Nickel Implant in Human Saliva

International Journal of Electrochemical Science, 2022
Titanium and its alloys have been widely adopted in dental prosthetics due to their excellent biocompatibility, light weight, high resilience and good corrosion resistance. The human oral cavity is the second largest microbial host system after the human
