Zinc Oxide Eugenol (ZOE) as a Root Canal Sealer
Zinc Oxide Eugenol (ZOE) is a widely used material in dentistry, particularly as a root canal sealer. It is a combination of zinc oxide powder and eugenol liquid. When mixed, it forms a paste that sets over time. Here are its main features:
Advantages of ZOE as a Root Canal Sealer
1. Biocompatibility: It is well-tolerated by periapical tissues.
2. Antibacterial Properties: Eugenol provides mild antibacterial effects.
3. Good Flow and Adaptation: It fills small irregularities and voids in the root canal system.
4. Radiopacity: ZOE sealers are radiopaque, making them visible on radiographs.
5. Ease of Use: It is easy to mix and apply.
6. Sealing Ability: Provides a good seal to prevent microleakage.
Disadvantages
1. Solubility: ZOE-based sealers tend to dissolve over time, which may affect long-term sealing.
2. Brittle after Setting: It can become brittle and fracture.
3. Delayed Setting in Moisture: Presence of moisture may slow the setting process.
4. Eugenol Sensitivity: Some patients may have sensitivity or allergies to eugenol.
Clinical Use
ZOE sealers are commonly used with gutta-percha in lateral or vertical compaction techniques for root canal obturation. While they are effective, newer materials such as resin-based, bioceramic, and silicone-based sealers are often preferred for better durability and sealing properties.
