Prognosis of Periodontal Disease

Question 1

factors to consider when determining prognosis of individual teeth

Answer 1

1. percentage bone loss or attachment loss
2. probe depth
3. distribution and type of bone loss
4. presence of severity of furcations
5. mobility
6. crown root ratio
7. tooth position/occlusal relationships
8. strategic value (ability to fxn in health)

Question 2

examples of guarded (questionable) progonsis

Answer 2

1. mobility of 2
2. grade 2 furcation
3. pocket depth or attachment loss greater than 7mm

Question 3

examples of hopeless prognosis

Answer 3

1. class 3 mobility
2. through-and-through furcation, with little to no interradicular bone and severe bone loss on all roots
3. a tooth that has supra-erupted and contacts the edentulous ridge

Question 4

factors to consider when determining overall prognosis

Answer 4

1. age
2. medical status
3. rate of progression
4. severity of bone loss
5. economics
6. etiology
7. patient’s motivation to save teeth and the dental practice considerations

Question 5

therapeutic prognosis

Answer 5

prediction of tooth loss with appropriate treatment, patient compliance and maintenance

Question 6

which are the earliest tooth to be lost due to perio disease?

Answer 6

1. maxillary 2nd molars
2. mandibular 2nd molars
3. maxillary and mandibular 1st molars

Question 7

which are the last teeth to be lost due to perio disease?

Answer 7

mandibular canines and premolars

Question 8

T/F: patients with untreated perio disease have 3X the rate of tooth loss as those who are treated and well maintained

Answer 8

true

Question 9

T/F: patients who are treated for perio disease, but have irregular or no perio maintenance, exhibit twice the tooth loss as those who are treated and well maintained

Answer 9

true

Question 10

sequence in interdisciplinary treatment planning

Answer 10

1. acute and urgent phase
2. anti-infective/etiotropic phase
3. periodontal surgery and pre-prosthetic surgery
4. reconstructive phase
5. periodontal maintenance therapy

Question 11

what is involved in the acute and urgent phase?

Answer 11

1. pulpal involvement
2. periodontal abscess
3. ANUG
4. deep caries
5. pulpitis

Question 12

what is involved in the anti-infective/etiotropic phase

Answer 12

1. initial periodontal therapy through non-surgical procedures
2. non-periodontal dental procedures (caries control, removal of defective restorations, edodontics, and strategic extractions of hopeless teeth)
3. periodontal re-evaluation following initial therapy

Question 13

what is involved in reconstructive phase?

Answer 13

1. castings
2. FPD’s
3. RPD’s
