Resorption Flashcards
Two studies who said that apical resorption is greater when there is pulp necrosis
Malueg 1996,
Frank 1990
What did Malueg 1996 and Frank 1990 say?
That apical resorption is greater when there is pulp necrosis
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
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
Who discussed bleaching-induced resorption being caused by cemental defects at the CEJ?
Rotstein 1991
Who examined predisposing factors for external cervical resorption? (ortho, bleaching, trauma)
Heithersay 1999
What did Heithersay find were the most common associations with cervical resorption?
Orthodontics, then trauma, then bleaching
Who treated external resorption with 90% TCA, curettage, NSRCT (if necessary) and restoration with GI and looked at success?
Heithersay 1999
Who recommends treatment of external cervical resorption with 90% TCA, curettage, NSRCT (if necessary) and restoration with GI
Heithersay 1999
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
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
Who did review article of external cervical resorption in 2009?
Patel 2009
Who said that CBCT diagnoses external cervical resorption better than a radiograph?
Patel 2009
How is 90% trichloroacetic acid thought to work on external resorptive tissue?
coagulation necrosis
