    Study Notes

    Furcation Involvement

    • Plaque, calculus, and bacterial debris can invade the furcation spaces of multirooted teeth, leading to periodontal disease.
    • Maxillary first premolars and molars, along with mandibular molars, are prone to furcation involvement due to their multiple roots.
    • The maxillary first premolar often exhibits fused roots with an apically positioned furcation area, resulting in a poor prognosis.
    • Maxillary molars have three roots, allowing furcation openings in several directions, complicating plaque control and prognosis.
    • Mandibular molars, possessing two divergent roots, tend to have a better prognosis for furcation involvement, particularly in the first molar.

    Treatment Modalities

    • Treatment aims to prevent further attachment loss and enhance maintenance of the furcation area.
    • Two primary approaches exist: traditional treatment and reconstructive/ regenerative treatment.
    • Considerations when choosing therapy include involvement degree, crown-root ratio, root length, and strategic value of the affected teeth.

    Tooth Anatomy Considerations

    • Short root trunks lead to earlier furcation involvement, while long trunks complicate instrumentation.
    • Concavity on root surfaces poses challenges for plaque removal but increases attachment area, often seen in maxillary first molar mesial roots.
    • Wide root separation enhances access for treatment, while cervical enamel projections favor plaque accumulation and necessitate removal.

    Bone Structure and Defect Classification

    • Bone shape around the furcation area includes horizontal and vertical components, determining furcation involvement grades (I-IV) and the nature of defects.
    • Alterations in bone structure can lead to challenging treatment scenarios with varying success rates based on the involvement grade.

    Reconstructive and Regenerative Procedures

    • Various grafting techniques, such as allografts and alloplasts, aim to enhance healing and tissue regeneration in the furcation area.
    • Techniques like citric acid root conditioning and guided tissue regeneration improve outcomes, but success diminishes in advanced involvement cases.

    Key Points

    • Furcation involvement is linked to bacterial plaque and predisposing anatomical factors.
    • Glickman's classification (Grade I-IV) helps diagnose involvement severity, complemented by probes and radiographs.
    • Treatments range from traditional methods, focused on maintaining health, to advanced regenerative procedures for deeper involvement.

    Odontoplasty and Osteoplasty

    • Odontoplasty reshapes tooth anatomy to improve access for plaque control, beneficial for Grade I and II defects.
    • Osteoplasty reshapes bone surfaces without removing supporting structures; ostectomy includes removal of supportive bone.
    • Both techniques seek to enhance plaque control, especially for shallow furcation invocations.

    Surgical Options

    • Root separation and resection apply to severe cases with significant bone loss, primarily in Class II or III furcations.
    • Hemisection and bicuspidization are common surgical procedures for managing multirooted teeth affected by severe disease.

    Indications and Contraindications

    • Indications for root resection include severe bone loss, unmanageable furcation invasion, and specific root conditions.
    • Contraindications involve systemic diseases, fused roots, and endodontic complications.

    Traditional Treatment Procedures

    • Focus on preventing disease progression through initial scaling, root planing, curettage, and odontoplasty.
    • For severe furcation involvement, surgical options may involve root resection, hemisection, or tunnel preparation to facilitate access.

    Access Improvement Techniques

    • Gingivectomy and apically positioned flaps can enhance access for plaque control and help resolve periodontal conditions effectively.
