“Quaternary ammonium compounds to prevent oral biofilm formation”
Mari Miura Sugii
1. Quaternary ammonium compounds are effective substances to kill cariogenic Streptococcus mutans. (This thesis)
2. Alkyl chains will increase the antimicrobial activity of quaternary ammonium groups. (Li F. et al., 2013)
3. Photopolymerization can diminish antimicrobial activity of quaternary ammonium compounds inserted in an organic matrix (This thesis)
4. The use of coatings with quaternary ammonium compounds is a suitable strategy to prevent the drawbacks of oral biofilm formation on metallic surfaces. (This thesis)
5. Release of quaternary ammonium compounds in high concentrations is cytotoxic but in the oral cavity this is a transitory process. (This thesis)
6. Tooth brushing will keep biofilm away but will also promote loss of quaternary ammonium content from a sealant. (This thesis)
7. You have to be as positive as quaternary ammonium compounds when working as a PhD.
8. The expectations are the factors leading to disappointments. 9. Believing in your own potential is not easy, but when you do
that you feel safe and fearless of the future.
10. In times of intolerance we need to practice kindness and empathy.
