Bioburden refers to all organic and inorganic remnants, including the numerous infectious organisms and bacterial biofilms found on the surface of – or inside – dental instruments before cleaning and decontamination, disinfection and sterilization. The larger the bioburden, the harder the object is to sterilize.

According to associate professor Dr. Mikael Zimmerman from Karolinska Institutet in Stockholm, Sweden, the fight against bioburden – and especially bacterial biofilm – is the most important factor if you wish to avoid cross-contamination in your dental clinic.

Biofilm – a Hard Nut to Crack

Certain bacteria can form biofilm, known in the oral cavity as dental plaque. The bacterial colony within biofilm has a very high resistance to chemicals and antibiotics, as well as to pH and temperature variations. Biofilms have been found to be involved in a wide variety of microbial infections in the body. Biofilms can also be found on dental instruments and must be removed via thorough cleaning procedures prior to sterilization.
