In this study a method of producing a large number of identical nanostructured surfaces is presented. E. coli wild type and deletion mutants of the type 1 fimbriae monomers FimA or FimH were tested for their ability to adhere to such surfaces with different interpillar distance of 100, 250, and 500 nm, respectively. An increase in interpillar distance (reduced surface coverage) was associated with reduced adhesion of E. coli wild type and the deletion mutants. In addition, the presence of a functional type 1 fimbria decreased adhesion to the nanopatterned surfaces in comparison to deletion mutants, leading us to the conclusion that there is a relationship between presence of a functional fimbriae and adhesion towards tested surfaces. The hypothesis that the presence of fimbriae had an effect on bacterial attachment to nanostructured surfaces was verified. These current results could provide insight into development of new nano-patterned structures with anti-adhesion bacterial properties.

The use of charcoal for oral hygiene purposes has long traditions in several countries. Products containing charcoal are constantly being introduced to the market, advertising various advantageous properties, such as a whitening effect and detoxification.

Aerosols are generated secondary to different treatment procedures and situations in the dental clinic. Aerosols in the dental clinic may be infectious and transfer disease between clinic staff and patients. The authors present and discuss different measures to reduce infection caused by exposure to microbial aerosols. It is unrealistic to expect that close range aerosols […]

Aerosol-generating procedures associated with oral care may involve risks for disease transmission between patients and dental staff. Article part I describes characteristics of aerosols and possible influence on health. This paper focuses on microbial aerosols and on situations and procedures that produce microbial aerosols in the dental clinic. Several forms of microbial aerosols are created […]

This study investigated the effect of surface nano-patterning on adhesion of an oral early commensal colonizer, Streptococcus mitis and the opportunistic pathogen Staphylococcus aureus and human fibroblasts (HDFa) in a laminar flow cell.
