What material is typically used for root canal sealing during obturation?

The material typically used for root canal sealing during obturation is cement type material, specifically gutta-percha. This material is favored because it is biocompatible, has excellent sealing properties, and effectively fills the root canal space to prevent the ingress of bacteria and pathogens. Gutta-percha is flexible, allowing it to adapt within the canal, and it also has moisture-resistant properties, which are essential for maintaining the integrity of the root canal filling over time.

The choice of cement type material highlights its effectiveness in achieving a proper seal, which is crucial for the success of the root canal treatment. It plays a vital role in preventing future infections and ensuring the longevity of the treatment. Other materials listed, while useful in dentistry, do not serve the primary purpose of root canal sealing in the same effective manner. For example, composite resin, glass ionomer, and amalgam serve different roles in restorative dentistry and are not ideal for this specific application.
