furcation involvement

fur·ca·tion in·volve·ment

(fŭr-kāshŭn in-volvmĕnt)
Extension of dental disease (involving pathologic resorption of alveolar bone and damage to periodontal ligament fibers) where roots of a multirooted tooth separate or divide.

Presence of inter radicular bone loss or furcation involvement (periapical or inter-radicular radiolucency)
Hemisection is a conservative treatment approach for multirooted teeth affected with caries, bone loss and furcation involvement. The term hemisection refers to the sectioning of a molar tooth with the removal of an unrestorable root which may be affected by periodontal, endodontic, structural (cracked roots) or caries.
Upon the patients' return, teeth 18, 17, and 16 all had class III furcation involvement with grade 3 mobility; they were extracted under full thickness flap allowing visibility of a 3-wall defect of 10 mm at the mesial of tooth number 13 which was then treated with guided tissue regeneration technique using bovine xenograft bone substitute Bioss[R] and resorbable collagen membrane Resolute[R].
(9,10) The degree of furcation involvement often serves as a prognostic factor and influences the selection of definitive and sometimes irreversible treatments.
A severe generalized horizontal bone loss associated with local vertical lesions and furcation involvement in the first quadrant was seen on the panoramic radiography.
[sup][1] For these reasons, explanations for the discrepancies between the locations of root-resected molars, in terms of flap surgery, could include differences in anatomical features, severity of furcation involvement, levels of self-accessibility to maintain oral hygiene, and optimal restorative rehabilitation.
Not one of us leaves calculus behind on purpose, so to be able to meticulously debride the roots in the furcations and 'visualize' root abnormalities (like resorption, fractures, perforations, furcation involvement) is extraordinary.
Furcation involvement is one of the major problems in the treatment of periodontal disease, and is directly associated with tooth loss.
The bone loss and furcation involvement associated with teeth 36 and 46 are most likely due to caries and endodontic European Archives of Paediatric Dentistry 12 (Issue 1).
It included clinical attachment, probing depth, gingival enlargement, tooth displacement, and furcation involvement. For this study clinical attachment was defined as the distance from the cement-enamel junction to the free gingival margin, and probing depth as the distance from the free gingival margin to the bottom of the pocket/sulcus.
Therefore, in order to decide whether the tooth is safe or not, data that have to be collected are probing depth, attachment level, mobility, inflammatory and hygiene indices, root anatomy, furcation involvement, and crown-to-root ratio [13,14], but not enough.
