Flashcards in Resorption Deck (14):
1

Two studies who said that apical resorption is greater when there is pulp necrosis

Malueg 1996,
Frank 1990

2

What did Malueg 1996 and Frank 1990 say?

That apical resorption is greater when there is pulp necrosis

3

Who proposed that apical resorption occurs because the CDJ at the foramen is very thin or absent, exposing mineralized dentin to resorptive clastic cells?

Trope and Chivian 1994

4

What did Rotstein 1991 say about external cervical resorption?

That cemental defects at the CEJ cause hydrogen peroxide from the pulp chamber of root-filled teeth to leak to the outside of the root and cause inflammation induced root resorption

5

Who discussed bleaching-induced resorption being caused by cemental defects at the CEJ?

Rotstein 1991

6

Who examined predisposing factors for external cervical resorption? (ortho, bleaching, trauma)

Heithersay 1999

7

What did Heithersay find were the most common associations with cervical resorption?

Orthodontics, then trauma, then bleaching

8

Who treated external resorption with 90% TCA, curettage, NSRCT (if necessary) and restoration with GI and looked at success?

Heithersay 1999

9

Who recommends treatment of external cervical resorption with 90% TCA, curettage, NSRCT (if necessary) and restoration with GI

Heithersay 1999

10

When Heithersay 1999 tx'd ecr with TCA, curettage, NSRCT if necessary and GI restoration, what were the outcomes?

After 3 years, cl I and II were 100% successful, class III 77.8% successful, and cl IV were 12.5% successful

11

Heithersay's definitions of root resorption (cl I-IV)

I: shallow dentin penetration
II: well-defined invasive resorptive lesion (little or no extension into radicular dentin)
III: Involves coronal third of root
IV: Beyond coronal third of root

12

Who did review article of external cervical resorption in 2009?

Patel 2009

13

Who said that CBCT diagnoses external cervical resorption better than a radiograph?

Patel 2009

14

How is 90% trichloroacetic acid thought to work on external resorptive tissue?

coagulation necrosis
