Material (sealer type) | Setting reaction | Adhesion to root dentine | Key properties (short list) | Main uses | |
|---|---|---|---|---|---|
ZOE-based sealer | ZnO + eugenol + resins/metal oxides/radiopacifiers | Chelation forming zinc eugenolate | Mainly mechanical; limited interaction with dentine | Long history, good flow, radiopaque, reasonably good seal, eugenol may be soothing | Sealer with gutta-percha in conventional RCT |
Resin-based sealer (e.g. epoxy) | Epoxy or other resin matrix + radiopaque fillers | Polymerisation (usually two-paste chemical cure) | Primarily mechanical with some resin tag penetration | Good flow, very low solubility, dimensionally stable, radiopaque, good long-term seal | Widely used with gutta-percha in most RCT cases |
