Thin encrustation of microbes embedded in extracellular POLYMERS adhering to surfaces such as teeth (DENTAL DEPOSITS), implants (PROSTHESES AND IMPLANTS), and catheters. Sometimes called polymeric adhesin but it is distinct from protein adhesin (ADHESINS, BACTERIAL). Biofilms are prevented by treating surfaces with DENTIFRICES; DISINFECTANTS; ANTI-INFECTIVE AGENTS and antifouling agents (PESTICIDES).
