Study Notes

Furcation Involvement

Furcation is the anatomical area where the roots of multi-rooted teeth divide.
Furcation involvement (or defect) refers to bone loss at the branching point of the roots.
Key factors influencing furcation involvement include:
- Root trunk length: The distance from the cement enamel junction to the entrance of the furcation.
- Root length: The overall length of the root.
- Interradicular dimensions: The space between the apices of the roots.
- Cervical enamel projections/enamel pearls: Extensions of enamel beyond the CEJ towards the furcation area.

Grading of Furcation Involvement

Glickman Classification is used to assess the severity of furcation involvement clinically:
- Grade I: The curvature of the concavity between the roots can be detected with a probe, but the probe cannot enter the space.
- Grade II: The probe penetrates into the furcation, but does not completely pass through to the other side.
- Grade III: The probe passes completely through the furcation, but it's not clinically visible because soft tissue still fills the furcation defect.
- Grade IV: The probe passes completely through the furcation, and the entrance to the furcation is clinically visible due to gingival recession.
Nabers Probe: A specialized probe used to measure furcation depth with markings at 3mm, 6mm, and 9mm.

Challenges for Patients and Clinicians

Patients with furcation involvement face:
- Difficulty keeping the area clean, increasing the risk of further bone loss and tooth loss.
Clinicians face:
- Complex treatment considerations, including specialist intervention.
- Challenging access for both patient and clinician, making cleaning and treatment more difficult.
- Less favorable prognosis compared to teeth without furcation involvement.

Treatment Options for Furcation Involvement

Treatment objectives:
- Remove bacterial plaque and biofilm to prevent further bone loss and tooth loss.
- Remove overhangs, calculus, excess cement, and other factors that make cleaning difficult for patients.
- Consider specialist intervention if necessary.
Treatment methods:
- Non-Surgical: Scaling and root planing, home care instructions with specific brushing techniques.
- Surgical: Guided tissue regeneration, furcation flap surgery, bone grafting.
- Tooth extraction and replacement: In cases of severe furcation involvement or poor prognosis.

Role of the Dental Hygienist/Dental Therapist (DH/DTH)

DH/DTHs play a crucial role in:
- Identifying furcation involvement during routine examinations.
- Educating patients on the importance of good oral hygiene specifically for furcation areas.
- Providing appropriate oral hygiene instructions and demonstrating effective brushing techniques.
- Performing scaling and root planing to remove plaque and calculus.
DH/DTHs collaborate with dentists to:
- Develop appropriate treatment plans.
- Monitor the progress of treatment.
- Provide ongoing oral hygiene maintenance and care instructions.
