Q

With individual tooth prognosis, what is the MOST IMPORTANT determinant:

A

Amount or percentage of attachment loss

17
Q

Why is the amount or percentage of attachment loss considered the most important determinant for individual tooth prognosis?

A

Because it influences mobility and crown/root ratio

18
Q

List the factors affecting individual tooth prognosis:

A
  1. amount or percentage of attachment loss
  2. bony defect topography
  3. pocket depth (needs to related to the attachment loss)
  4. rate of attachment loss
  5. systemic/environmental factors
  6. patients compliance and oral hygiene control
19
Q

When determining the pocket depth effects on the individual tooth prognosis, this needs to be related to:

A

attachment loss

20
Q

What are some systemic/environmental factors that affect individual tooth prognosis?

A
  1. smoking
  2. diabetes
  3. stress
  4. genetics
  5. medications inducing gingival enlargements
  6. systemic disease affecting perio
21
Q

What are the anatomical factors that affect individual tooth prognosis?

A
  1. excessive occlusal forces
  2. overhang or defective subgingival restorations
  3. cervical enamel projections (CEP’s)/enamel pearls
  4. developmental/palatogingival grooves
  5. root concavities
  6. root forms and lengths
  7. furcation and intermediate bifurcation ridges
  8. accessary canals
  9. root proximity
  10. tooth mobility
