Q

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

A

amount or percentage of attachment loss

17
Q

Why is the amount of 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 factors affecting individual tooth prognosis:

A
  1. amount or percentage of attachment loss
  2. bony defect topopgraphy
  3. pocket depth (needs to relate 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 depths 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. diabets
  3. stress
  4. genetics
  5. medications inducing gingival enlargements
  6. systemic disease affecting perio
21
Q

What are some anatomical factors that affect individual tooth prognosis?

A
  1. excessive occlusal forces
  2. overhand or defective subgingival restorations
  3. cervical enamel projections (CEP’s)/ enamel pearls
  4. Developmental/ Palatogingival grooves
  5. Root concavities
  6. Root form and lengths
  7. Furcation and intermediate bifurcation ridges
  8. Accessory canals
  9. Root proximity
  10. Tooth mobility

A

anatomical factors affecting individual tooth prognosis

23
Q

The most common locations for a CEP is the:

A

buccal surface of 2nd mandibular molar
