Research Abstract
This research evaluated the bactericidal effects of peroxynitric acid (HOONO2; PNA) on biofilms formed on titanium surfaces. Streptococcus gordonii was cultured on titanium discs that were then used to evaluate the bactericidal effects of PNA. Using low concentration of PNA, the bacterial count based on a CFU assay reached an undetectable level within 10 s.Bacillus subtilis solution was coated on the dental model, and impression taking of the model was done by dental impression material. Dental impression material was disinfected by PNA, and bactericidal effects were evaluated. The bacterial count based on a CFU assay reached an undetectable level within 10 minutes. PNA is useful for sterilizing biofilms on titanium surfaces and dental impression material that have been contaminated with bacteria.
