摘要: Streptococcus mutans is one of the more significant pathogens involved in development dental caries humans. The purpose this research was to design a TiO2-coated instrument and determine bactericidal effects onS. mutants. TiO2 photocatalytic films were prepared by low-pressure metal-organic chemical vapor deposition (LPMOCVD) method using titanium tetraisopropoxide (TTIP) as precursor. reaction carried out on pyrex petri dish with an ultraviolet (UV) light emitting diode (LED) illuminator or fluorescent lamp source. Our data indicates that relative survival ratio ofS. when plated onto under exposure UV-A for 15 min 0.01%. In addition, source also had theS. films. These results indicate materials devices may be useful treatments prevention carious enamel demineralization.
