What is the function of a post in dental procedures?

  1. To smooth amalgam

  2. To add support to a tooth

  3. To carve amalgam in proximal areas

  4. To mix and place cavity liner

The correct answer is: To add support to a tooth

The function of a post in dental procedures primarily relates to providing additional support to a tooth, particularly in cases where a significant portion of the tooth structure has been lost due to decay or trauma. When a tooth is severely weakened, inserting a post into the root canal can help anchor a restoration, such as a crown, ensuring that it remains stable and functional. Posts are integral in maintaining the structural integrity of the tooth after endodontic treatment (root canal therapy) and help distribute the forces that occur during chewing. This support is crucial in extending the lifespan of the treated tooth and restoring its functionality. The other options relate to different aspects of dental procedures, such as finishing the restoration or preparing materials, but do not directly involve the role of a post, which is specifically to reinforce and support a damaged tooth structure.
