Abstract:
Objectives:This study aimed to evaluate the antibacterial activity of green tea extract containing dentifrice on oral disease-causing bacteria.
Methods:The antibacterial activity of green tea extract containing dentifrice was examined on the gram-positive bacteria Actinomyces israelii, Enterococcus faecalis, Filifactor alocis, Streptococcus mutans, and gram-negative bacteria Fusobacterium nucleatum, Porphyromonas gingivalis. A. israelii, E. faecalis, F. alocis, S. mutans, F. nucleatum, and P. gingivalis were cultured with green tea extract containing dentifrice or control dentifrice; they were then incubated at 37°C under anaerobic conditions and cultured. Following incubation, a microplate reader was used to measure the absorbance and observe the number of bacteria. Statistical significance tests were conducted using the Mann-Whitney test and SPSS 24.0.
Results:Green tea containing dentifrice has antibacterial activity against A. israelii, E. faecalis, F.alocis, S. mutans, F. nucleatum, and P. gingivalis. Furthermore, green tea containing dentifrice killed more than 99.99% of 4 strains of gram-positive bacteria and 2 strains of gram-negative bacteria.
Conclusions:The detergent with green tea extract is significantly reduced the bacteria applied in this experiment; dentifrice has a bactericidal and antibacterial effect against oral bacteria. Therefore, the detergent with green tea extract is thought to be helpful in preventing dental caries and periodontal disease.
