Question 7

(KWOK AND CATON (2007) Prognosis)

treatment and periodontal maintenance. Future loss of the periodontal supporting tissues is
unlikely if these conditions are met

Answer 7

Favorable

Question 8

Question 21

Amount of bone loss is about 3.6 times higher

than normal in teeth that have more or less root proximity?

Answer 21

Teeth having roots closer together have more rapid bone loss

Answer 22

Max molars

Question 23

-More rapid bone loss

Answer 23

Furcation ridge

Question 24

DOES A SUCCESSFUL ENDODONTIC TX EFFECT PERIO PROGNOSIS?

Answer 24

Does not

Question 25

Re-evaluation of periodontal case should occur about __
weeks after completion of SRP.
‣ Allows time for healing of epithelium and CT

within 3-4 weeks after removal of calculus and local irritants

Answer 25

4-6 weeks

Question 26

Healing after STP: Formation of __________
‣ this attachment epithelium appears 1-2 weeks after therapy
‣ Gradual reductions in inflammatory cell population, crevicular fluid
flow, and repair of connective tissue will result in less
inflammation, redness and swelling

Answer 26
