Furcations- Review Flashcards
Goals of furcation therapy include:
- arrest active disease
- prevent further loss of attachment
- regenerate loss periodontium
- prevent disease recurrence
Objectives of furcation therapy include:
- access for home care
- access for maintenance
- establish physiologic bone and tissue architecture
T/F: Grade/Class II or Grade/Class III furcation involvement automatically places a patient into stage III-IV peridontitis - according to 2017 AAP classification
True
Etiology of furcation bone loss:
- Plaque (advancing plaque front 1mm from JE) attachment loss
- developmental anomalies (furcation concavities)
- iatrogenic errors
- Pulpal involvement (via lateral canals or endo-perio lesions)
- occlusal trauma
Diagnosis of furcations can be done using ____ as well as ____
probes; radiographs
Type of probing that measures the VERTICAL attachment loss (extent of horizontal loss will not be detected):
Standard “straight” probing
Type of probing that determines horizontal attachment loss:
Nabers “curved” probing
What is used to probe furcations?
Nabers probe
If a mesial furcation is detected, where should the probe be placed to access it:
palate
Location of furcatino entrances for maxillary molars:
Mesial furcation:
Distal furcation:
Buccal furcation:
Mesial furcation: located towards palatal 1/3 so probe from PALATAL
Distal furcation: located in the mid 1/3 under contact point so probe from PALATAL or BUCCAL
Buccal furcation: probe from BUCCAL
Most commonly used classification for furcations:
Goldman & Glickman
Classify the following:
-Pocket formation into the flute of the furca, but the interradicular bone is intact
-Loss if attachment
-Bone loss is from buccal to lingual or palatal to buccal (not losing bone in a horizontal direction)
Goldman incipient
Glickman grade I
Classify the following:
-Loss of interradicular bone with pocket formation of varying depths in to the furca, but NOT completely through to the other side
(Interraducular bone in tact)
-Can be shallow or deep
-Bone loss is starting to be lost horizontally
Goldman cul-de0sac or Glickman grade II (shallow & deep)
What treatment should be done for Goldman cul-de-sac or Glickman grade II?
Would need to reflect a flap because tissue is going to be up to CEJ
Classify the following:
-Complete loss of interradicular bone with pocket formation, allowing probe to pass completely to the other side
-AKA: Isolated root
-Soft tissue way may still be intact making it difficult to access and difficult for patient to clean
Goldman through & through or Glickman Grade III
Classify the following:
-Loss of attachment and gingival recession that has made the furcation clearly visible to clinical examination
-accessible and visible to clinical examination due to soft tissue recession
Glickman Grade IV
In addition to Goldman and Glickman, what are two other classification systems?
Hamp & Tarnow
Classification of the HORIZONTAL component of furcation involvement:
Hamp classification
Classification of the VERTICAL component of furcation involvement:
Tarnow classification
Describe the following degrees of HAMP classification:
Degree 1:
Degree 2:
Degree 3:
Degree 1: less than 3 mm of horizontal loss
Degree 2: greater than 3 mm of horizontal loss but NOT all the way through
Degree 3: through and through
Classification of the VERTICAL component of furcation involvement:
Tarnow
Describe the following subclasses of Tarnow Classification:
Subclass A:
Subclass B:
Subclass C:
Subclass A: Vertical loss up to 1/3 of furca (1-3mm)
Subclass B: Vertical loss up to 2/3 of furca (4-6mm)
Subclass C: Vertical loss into the apical 1/3 of furca (>7mm)
Anatomical considerations for furcation management include:
- cervical enamel projections
- root trunk length
- furcation root concavities
- furcation entrance diameter
- pulpal interrelationship
- bifurcational ridges
How commonly do we see cervical enamel projections (CEP)?
17-33%
