Furcation

The furcation is an area of complex anatomic morphology that may be difficult or impossible to debride by routine periodontal instrumentation and furcation involvement is a condition in which periodontal fibre attachment is lost between the roots of multirooted teeth, It has been defined as ¿bone resorption and attachment loss in interradicular space that results from plaque associated periodontal disease¿. Such a condition is reported to considerably increases the risk of tooth loss. This presence of furcation involvement is one clinical finding that can lead to a diagnosis of advanced periodontitis and potentially to a less favourable prognosis for the affected tooth or teeth. Furcation involvement, therefore, presents both diagnostic and therapeutic dilemmas and represents a formidable problem in the treatment of periodontal disease, principally related to complex and irregular anatomy of furcation.
