Perfectus Biomed have experience in oral biofilm assays, antimicrobial polymers and bacteriostatic and bactericidal differentiation.
The concept of chronic microbial infections, specifically the term biofilm, entered the scientific and microbiological world in relation to dental biofilms, an example of which is plaque.
Biofilms are problematic for the dental industry as dental unit waterlines can become contaminated with environmental microorganisms, forming biofilms that provide nutrients and protection to the resident microorganisms. Due to the force of liquid through the waterlines, bacteria may detach from the walls and contaminate the water stream, putting patients and healthcare professionals at risk of infection.
Biofilm removal techniques and products have also undergone a large amount of research within the dental world. Removal techniques include teeth brushing and flossing, as well as biofilm disruption agents found in toothpastes and mouthwashes. Despite the high body of knowledge in the dental industry, there is still a lot of research and development required. This includes the development of products that disrupt and remove oral biofilms as well as anti-microbial products to prevent and remove biofilm material. Anti-microbial products can also prevent chronic microbial build-up in dental unit waterlines and on dental surfaces equipment. Perfectus Biomed assess the biofilm removal and prevention properties of products to BS EN ISO 16954 methodology.
