Abstract:

Periapical biofilm refers to the biofilm that exists on the cementum of the root surface of infected root canals. It is commonly found in refractory periapical periodontitis or persistent periapical periodontitis, which leads to the non-healing of periapical periodontitis. Because of its special location and firm attachment to apical surface, it is difficult to clear up and has brought great challenges to infection control. How to effectively remove the periapical biofilm is the focus and hot issue of clinical attention. This review highlighted the basic and clinical research of the methods of removing periapical biofilm in recent years.

Key words: Periapical biofilm, Extraradicular biofilm, Endodontic surgery, Extraradicular infection, Chronic periapical periodontitis
