Prevent microleakage
-
Lubricate during obturation
-
Provide antimicrobial action
Types of Sealers:
| Type | Examples | Properties |
|---|---|---|

| Epoxy Resin-based | AH Plus, AH 26 | Strong adhesion, low solubility, long setting time |
| Calcium Hydroxide-based | Sealapex, Apexit | Antimicrobial, biocompatible, but less adhesive |
| Bioceramic-based | iRoot SP, EndoSequence BC | Bioactive, excellent sealing, promotes healing |
| Glass Ionomer-based | Ketac Endo | Good adhesion, limited antimicrobial action |
