Adhesion of Methicillin-Resistant Staphylococcus aureus and Candida albicans to Parylene-C-Coated Polymethyl Methacrylate.

Purpose: To determine whether coating polymethyl methacrylate (PMMA) discs with Parylene-C would reduce Staphylococcus aureus and Candida albicans biofilm formation.

Materials And Methods: MRSA and Candida albicans single and dual biofilms were grown for 48 hours in artificial saliva on parylene-C-coated or uncoated PMMA, and the viable biofilm colony-forming units were counted.

Results: There was no significant difference in the count of viable methicillin-resistant Staphylococcus aureus or Candida albicans recovered from single- or dual-species biofilms between coated and uncoated PMMA discs.

Aggregatibacter actinomycetemcomitans serotype prevalence and antibiotic resistance in a UK population with periodontitis.

Objectives: Aggregatibacter actinomycetemcomitans is a recognised pathogen involved in aggressive periodontitis. Seven serotypes of A. actinomycetemcomitans exist with a range of virulence and distribution dependent on ethnicity and geography.

In vitro evaluation of the antibiofilm properties of chlorhexidine and delmopinol on dental implant surfaces.

Biofilm development on the internal surfaces of dental implants and dental implant components may be associated with peri-implant hard and soft tissue abnormalities. Currently, no protocols have been established for effective disinfection of removable implant components. The purpose of this study was to evaluate the antibiofilm properties of commonly used dental antimicrobial agents (chlorhexidine and delmopinol) on multispecies biofilms.
