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
