periodontal regeneration

Question 1

root surface demineralization

Answer 1

1) citric acid
2) tetracycline
3) EDTA

Question 2

osseous grafting

Answer 2

1) autograph
2) allograph
3) xenograft
4) alloplast

Question 3

biologic mechanisms

Answer 3

1) osteoconductive that migrates
2) osteoinductive with GFs
3) osteogenic (autograft)

Question 4

guided tissue regeneration

Answer 4

1) membranes block migration of epithelium
2) creates a space for healing to occur, stabilize the blood clot, keeps mature CT off the root
3) if CT remains in contact with the root, it causes resorption
4 )bone fill will not go past the defect, but CT attachment will

Question 5

conventional epithelial surgery

Answer 5

1) remove epithelial lining
2) epithelial cells, CT, bone cells migrate
- most likely epithelial cells are the fastest
- if bone cells win, its ankylosis

Question 6

repair

Answer 6

1) restoration of tissue with does not replicatie the structure and function of lost tissue
- epithelial long junctional attachments

Question 7

reattachment

Answer 7

1) reunion of CT with a root surface on which a viable PDL persists
2) ex acute abscess

Question 8

new attachment

Answer 8

1) reunion of CT with a root surface which has been deprived of its periodontal ligament
2) ex chronic periodontitis with calculus

Question 9

gore tex

Answer 9

1) maintains space for regeneration
2) stabilizes clot
3) inhibits epithelial down growth
4) keeps mature CT off root surface
5) made of expanded PTFE

membrane

Question 10

indications

Answer 10

1) furcation
-esp class 2 on mandibular molars
2) infrabony defects
3) root coverage
4) ridge augmentation

Question 11

contraindications

Answer 11

1) horizontal bone loss
2) shallow infrabony defects
3) class III furcations
4) class II maxillary furcas
5) one walled infrabony defects

Question 12

clinical techniqeu

Answer 12

1) sulcular incision with FTP
2) debridement
3) addition of membrane and suture
4) flap is sutured in place too
- NO EXPOSED MEMBRANE
5) 4-6 weeks the membrane is removed

Question 13

cytoplast

Answer 13

1) like goretex but made of dense PTFE
2) less concerning if it is exposed

Question 14

other biologics

Answer 14

1) BMP
2) PDGF
3) VEGF
4) TGF-beta
5) platelet rich plasma
6) platelet rich fibrin

Question 15

bad outcome cn be due to

Answer 15

1) smoke
2) immunocompromised
3) poor OH
4) nature of defect
5) flap design
6) site preparation
7) tooth mobility
8) trauma
9) infection
