POST & CORE

 When there isn’t enough crown structure
 Can put on same day as OBT
 Depends on the remaining coronal structure of the nature tooth – indication
 Function – retention of core
 PIEZO REAMER is used to make post space inside the canal
 Continuous wave / sectional GP / system B technique
 Resin – modified GIC is ideal to cement post
 Factors that affect its efficiency:-
a. Length :-
 2/3rd of the canal – most imp
 4-5mm length from apex
 4mm- minimum GP to be left
 5mm- ideal GP to be left in the canal
b. Diameter :-
 Greater the diameter, more the efficiency
c. Surface Texture :-
 Rough surface is preferable than smooth ones. Roughened / serrated
d. Post material :-
 Pre-fabricated posts such as fibre posts & metallic posts
 Custom made posts such as casted posts
e. Post shape :-
 Parallel is preferred than tapered ones
 More retention

CASTED POSTS
 Indicated in anteriors & flared canals

FIBRE POSTS
 Can absorb shock
 Best in posteriors
 Can withstand masticatory forces

METAL POSTS
 Least preferred
 May fracture the tooth

CORE BUILD-UP
 Core should take the shape of natural tooth
 Should extend to contra-bevel to produce ferrule effect
NB: Management of re-infected post & core treated tooth:

- Apicocectomy
- If not possible go for extraction
- Can’t do re-RCT here usually
