Oral medicine news According to a new study, dental bib holders can be contaminated with microbes such as pseudomonas. The study took place in Germany and indicated that 2/3 of the dental bib holders were contaminated with this and other bacteria.

30 metal and plastic dental bib holders were examined by a team from the Witten/Herdecke University in Witten, Germany. Professor Stefan Zimmer, lead investigator of the study and scientific director at the Witten/Herdecke University, said “The analyses of the bacterial load showed that 70 per cent of all reusable bib holders were contaminated with bacteria. The predominant colony types identified were staphylococci and streptococci. On several bib chains, we also found various bacterial rods, pseudomonas, fungi and other types of cocci,”

Professor Zimmer continued “Although the bacteria found in this study were all non-pathogenic, in principle reusable bib holders can cross-contaminate dental patients.” Although the majority of the bacteria detected on the bib holder were not harmful, they represent a potential problem for immune-suppressed patients.

Dental bib holders can result in an infection risk to patients via by way of cross contamination. Other previous studies reported high levels of contamination on dental bib holders. The identified bacteria included pseudomonas, E. coli and S. aureus.
