Abstract:

In order to investigate the efficacy of commercial toothpastes with bacteriostatic effect or antibacterial effect, the cylinder plate method was introduced to test the bacteriostatic effect on common oral pathogenic bacteria. Lactobacillus acidophilus (LA), Enterococcus faecalis (EF), Staphylococcus aureus (SA), Porphyromonas gingivalis (PG), S. mutans (SM),Streptococcus mutans clarke (SMC), and Pseudomonas aeruginosa (PA) were mainly selected. The results show that 16 kinds of toothpastes tested have different degrees of inhibition zones against 7 common oral pathogenic bacteria. MIC and MBC experiments of the tested toothpastes were carried out simultaneously, and the advantages of the experimental methods and the actual status of the selected commercial antibacterial toothpastes were briefly analyzed. Some suggestions are provided for the specification of the efficacy claims and nominal terms of toothpaste promotion.

Key words: antibacterial toothpaste, oral pathogenic bacteria, cylinder plate method
