Study Notes
Furcation Definition
- The area where the roots of a multi-rooted tooth divide.
- Bone loss at this branching point is called a furcation defect or furcation involvement.
Furcation Anatomy
-
Glickman Classification (1953) grades furcations based on bone loss and gingival recession severity:
- Grade I: Probe tip detects concavity but cannot enter the space.
- Grade II: Probe penetrates the furcation but does not go through to the other side.
- Grade III: Probe passes completely through the furcation but is not visible due to soft tissue filling the defect.
- Grade IV: Probe passes completely through the furcation, and the entrance is clinically visible due to gingival recession.
- Other factors influencing furcation assessment:
- Root trunk length: Distance from the cement-enamel junction to the furcation entrance.
- Root length: Overall length of the root.
- Interradicular dimensions: Degree of separation/difference in the number of diverging roots.
- Cervical enamel projections/enamel pearls: Enamel extensions beyond the CEJ towards the furcation area.
Challenges and Impact of Furcations
-
Patient challenges:
- Unsightly appearance, especially with a broad smile.
- Food packing and trapping.
- Difficulty cleaning.
- Sensitivity with exposed dentine and potential root caries.
- Impact on long-term tooth prognosis.
Assessment of Furcations
-
Examination:
- Assess gingival tissues for inflammation, probing depths, and recession.
- Radiographs are essential to visualize bone loss.
- Use a Nabers probe for specific furcation assessment.
-
Secondary factors to consider:
- Overhanging restoration, crown margin, calculus deposits, and possible accessory root canals.
Furcation Treatment
-
Objectives:
- Remove bacterial plaque/biofilm.
- Eliminate secondary local factors.
- Prevent further attachment loss.
- Preserve tooth function.
-
Initial treatment options:
- Patient education and motivation, including proper oral hygiene techniques.
- Non-surgical periodontal therapy.
- Close monitoring for progression.
Restorative and Surgical Treatments
-
Restorative:
- Endodontic therapy.
- Possible restorative procedures.
-
Surgical:
- Guided tissue regeneration (GTR).
- Guided bone regeneration (GBR).
- Root resection.
- Root separation.
- Furcation plasty.
Furcation Plasty
- Involves removing tooth substance (odontoplasty) and remodeling alveolar bone at the furcation entrance (osteoplasty).
Importance of Monitoring
-
Regular evaluation:
- Grade and record furcations at every appointment.
- Reinforce optimal oral hygiene.
- Consider specialist referral if furcation progression occurs.
-
Factors influencing prognosis:
- Overall periodontal status.
- Age.
- Plaque control.
- Smoking habits.
- Bruxism.
Summary
- Thoroughly assess furcations during periodontal examinations.
- Educate patients about furcations and their implications.
- Choose appropriate treatment modalities based on the individual case.
- Monitor progress closely and refer patients to specialists if necessary.
