Aug 30, 2024 · A furcation defect is caused by severe periodontitis, a very advanced form of gum disease. Gum disease is an infection of the periodontium, the gums, connective tissues and bone that hold the teeth in place.
May 23, 2016 · Class III: Probe passes completely through the furcation but is not clinically visible because the soft issue still fills the furcation defect. Class IV: Probe passes completely through the furcation and the entrance to the furcation is clinically visible because of gingival recession.
In dentistry, a furcation defect is bone loss, usually a result of periodontal disease, affecting the base of the root trunk of a tooth where two or more roots meet (bifurcation or trifurcation). The extent and configuration of the defect are factors in both diagnosis and treatment planning.

A key factor in both the development and the treatment of furcation involvement is the root trunk length. The distance from the cementoenamel junction to the entrance of the furcation can vary extensively. Teeth may have very short root trunks, moderate root trunk length, or roots that may be fused to a point near the apex (Figure 62-3). The combin...
The mesial root of most mandibular first and second molars and the mesiofacial root of the maxillary first molar are typically curved to the distal side in the apical third. In addition, the distal aspect of this root is usually heavily fluted. The curvature and fluting may increase the potential for root perforation during endodontic therapy or co...
The anatomy of the furcation is complex. The presence of bifurcational ridges, a concavity in the dome,11 and possible accessory canals16 complicates not only scaling, root planing, and surgical therapy,28 but also periodontal maintenance. Odontoplasty to reduce or eliminate these ridges may be required during surgical therapy for an optimal result...
Cervical enamel projections (CEPs) are reported to occur on 8.6% to 28.6% of molars.26,27,35 The prevalence is highest for mandibular and maxillary second molars. The extent of CEPs was classified by Masters and Hoskins27 in 1964 (Box 62-1). Figure 62-4 provides an example of a grade III CEP. These projections can affect plaque removal, can complic...
The dental and periodontal condition of the adjacent teeth must be considered during treatment planning for furcation involvement. The combination of furcation involvement and root approximation with an adjacent tooth represents the same problem that exists in furcations without adequate root separation. Such a finding may dictate the removal of th...
A grade I furcation involvement is the incipient or early stage of furcation involvement (see Figure 62-6, A). The pocket is suprabony and primarily affects the soft tissues. Early bone loss may have occurred with an increase in probing depth, but radiographic changes are not usually found.
Dec 4, 2021 · Learning Objectives. Recognize the effect of furcation involvement on tooth prognosis. Develop strategies for managing furcation involvement. Describe surgical methods for Class I and Class II furcation involvement. Describe surgical methods for deep Class II and Class III furcation involvement.
Aug 28, 2021 · In this review, they examined specific clinical scenarios and revealed that regenerative approaches are predictable treatment options for class II furcation (Fig. 8.2a–d) defects on the buccal, mesial, and distal of maxillary molars and buccal and lingual of mandibular molars.
Feb 1, 2015 · A summary of the main findings of previously published systematic reviews and the available evidence relative to the indication of regenerative approaches for the treatment of furcation defects compared with conventional surgical therapy are presented.
