2/16/17 Diagnosis and Treatment of Furcation Flashcards
What do furcations on teeth provide?
-Areas for collection of biofilm
What is the primary reason we pull flaps?
-To gain access to the root surface
What is the primary etiology on furcations invasions?
-Bacterial plaque
The extent of attachment loss required to produce a furcation defect is variable and related to local anatomic factors such as what?
- Root trunk length (short/long)
- Root Morphology
- Local development anomalies such as CEPs
What is the root trunk length?
-The distance from the CEJ to where the root starts to diverge
What are secondary etiologies of isolated FI?
- Trauma from occlusion (brux)
- Cervical Enamel Projections (frequent on facial of mandibular 1st and 2nd molars)
- Pulpal periodontal disease
- Iatrogenic factors
- Root fractures
What is the preferred attachment to the teeth?
-A connective tissue attachment
T/F Junctional epitheliums attach very well to enamel
True
On a healthy tooth where do you find the junctional epithelium?
-Enamel
What does pressure on bone do?
-Resorb
T/F Class 5 lesions can lead to furcation involvement
True
Can you test for a root fracture if the patient has been anesthetized?
-No
What Glickman classification is an incipient or early stage of furcation with radiographic findings not usually seen?
-Grade I (Class I)
What Glickman classification is a culdesac with a definite horizontal component that may or may not be seen radiographically?
Grade II (Class II)
What Glickman classification has no bony attachment to the dome or roof of the furcation?
-Grade III (Class III)
