What is typically assessed through percussion in a dental examination?

1. Tooth sensitivity

2. Gum recession

3. Bone structure

4. Tooth vitality

The correct answer is: Tooth vitality

Percussion is a diagnostic technique used in dentistry to assess tooth vitality. By tapping on a tooth with an instrument, a dental professional can observe the response to determine whether the tooth is healthy or if it might be experiencing issues such as inflammation, infection, or necrosis. A vital tooth typically reacts differently compared to a non-vital tooth, and this can provide valuable information about the tooth's health. Dental professionals often utilize percussion to help diagnose conditions like pulpitis or apical periodontitis, where the pulp of the tooth becomes inflamed or the surrounding bone is affected. The sensitivity of the tooth to percussion indicates how well the tooth is functioning, making it a crucial part of a comprehensive dental examination. Understanding how percussion relates to tooth vitality is essential in evaluating a patient's dental health and guiding appropriate treatment decisions.
