Which materials are commonly used to cement points in a root canal?

1. Composite resins

2. Zinc oxide and eugenol mixtures

3. Polymer-based adhesives

4. Glass ionomer cements

The correct answer is: Zinc oxide and eugenol mixtures

Zinc oxide and eugenol mixtures are commonly used as a cementing agent in root canal treatments due to their favorable properties for this specific application. This material provides excellent sealing capabilities, helping to prevent bacterial infiltration into the root canal system, which is crucial for the success of endodontic therapy. The eugenol component has soothing qualities for inflamed dental tissues, making it advantageous for the sensitive environments encountered during root canal procedures. Additionally, zinc oxide and eugenol mixtures exhibit good antimicrobial properties, which enhance their effectiveness in controlling infection within the canal. These characteristics make them a preferred choice among dental professionals for cementing points, such as gutta-percha, during root canal therapy.
