Q
**
when do you do pulp capping in clsoed apex
A
- when reversible pulpitis with pulpal exposure , 4 conditions
1. Sound dentine surrounding exposure
2. continous blood filled pulp
3. bleeding controlled within 2mins
4. no dentine chips displaced
-
if not pulpotomy
2
Q

A
- irreversible pulpitis with pulpal exposure with

2. bleeding controlled within 2 mins
if not pulpectomy
3
Q
what are the file motions
A
- watch winding
- filing
- reaming
- balanced forced motion
- envelope of motion
4
Q
whats success of RCT involve - (monitoring)
4 elements
A
- no symptoms
- no signs
- radiograohic evidence of resolution of any periradicular lesion ( up to 4 years) - no enlargment
- tooth still in function
5
Q
indication of Re-RCT
from ESE QA guidelines -2006
A
- Teeth with inadequate root canal filling with radiological findings of developing or persisting apical periodontitis and/ or symptoms
- Teeth with inadequate root canal filling when the coronal restoration requires replacment or the coronal dental tissue is to be bleached
6
Q
what can you use to remove canal GP
A
- coronal third bulk: heated plugger/ US/ gates glidden
- solvent (chlorofrom/ eucalyptus oil)
- R 25
7
Q
whats the disadvantage of using solvent
A
