(amalgam)
- Insoluble
- No interference with
filling setting reaction
- Radiopaque
- Calcium hydroxide
- Composition
- 2 pastes - base & catalyst
- Setting reaction = Chelation
- Advantages
- Alkaline
- Anti-microbial
- Encourages tertiary dentine deposition
- Compatible with composite
- Disadvantages
- Very soluble
- Weak
- Types
- Setting
- Cavity liner
- Direct pulp cap
- Indirect pulp cap
- Stepwise excavation
- Non-setting
- Root canal temporisation
- ZOE
- Composition
- Zinc oxide
- Eugenol
- Setting reaction = Acid base
- Advantage
- Thermal, chemical & electrical insulator
- Anti-microbial
- Disadvantages
- Very soluble
- Weak & brittle
- Not compatible with composite
- Uses
- Liner in Primary E Pulpotomy
- Restored with PFMC or
GIC + composite
- Temporarising access cavity
- Short-term,
non-load bearing
- Sedanol
- Accelerated
- Cavit
- Kalzinol
- Resin-modified
- Longer-term,
load bearing
- IRM
- Reinforced with polystyrene
- GIC
- Advantages
- Least soluble
- Strongest
- Compatible with composite
- Use
- Layer on top of sublining
- CaOH
- Due to solubility & poor strength
- ZOE
- To prevent interference when
restoring with composite
- Indirect pulp cap in Primary teeth
- EBA
