Furcation Mgmt 2

Question 1

• Removing the roof of the furcation
  may improve patient’s access for
  plaque control. Indicated with Grade
  I and shallow Grade II furcations.
  Must be conservative or root
  sensitivity can result. An option, but
  rarely used.

Answer 1

Odontoplasty

Question 2

What tool is best to SRP furcation areas?

Answer 2

cavitron

Question 3

• Creation of a furcation tunnel used with
  deep Grade II and Grade III furcations.
  Must have divergent roots and good
  patient home care.
• Disadvantage of caries, and pulpal
  issues.
• Caries seen in 24% of 156 tunnels with
  rigorous maintenance, fluoride, and CHX

Answer 3

Tunnel preparation

Question 4

Indications for _____ _________
* Severe bone loss
* Close root proximity
* Inability to perform home care
* Strategic tooth
* Root fracture
* Unable to treat involved root with
endodontics (but able to complete
endodontics within two weeks if vital root
amputation)

Answer 4

root resections

Question 5

• If access for plaque control cannot be
  done in a furcation with severe bone loss
  on one of the roots but good support on
  the possible remaining roots.
• Study of 100 teeth (50 max. and 50
  mand. molars) after ten years found that
  62% were still in function. Failures mainly
  caused by root fracture*.

Answer 5

Root Resection

Question 6

Contraindications for ________
* Severe bone loss on retained roots
* Unable to do endodontics on retained roots
* Fused roots apical to furcation
* Poor plaque control
* Mobile teeth
* Long root trunk length
* Poor medical health
* Economics
* Age and type of periodontitis

Answer 6

root resection

Question 7

Is regeneration or osseous grafting better in furcations?

Answer 7

Regeneration

Question 8

What teeth don’t respond well to furcation therapy?

Answer 8

Molars

Question 9

Grade ____ furcation therapy
Control of inflammation through

indicated at reevaluation
* Odontoplasty if indicated (??)

Answer 9

Grade 1

Question 10

Grade ____ furcation therapy
* Control of inflammation through
plaque control and root
preparation
