What is the purpose of percussion in dental examinations?

To measure gum health
To evaluate the decay of a tooth
To determine sensitivity of a tooth
To assess tooth stability by tapping

The correct answer is: To assess tooth stability by tapping

The purpose of percussion in dental examinations is to assess tooth stability by tapping. This technique involves gently tapping on the tooth with a dental instrument or finger to evaluate its response. When a healthy tooth is tapped, it typically should not cause discomfort or pain. However, if a tooth is affected by an underlying issue such as an abscess or other dental problem, tapping may elicit pain or discomfort. This response provides valuable information regarding the health and stability of the tooth, helping the dental professional determine further action or treatment needed. This method is critical for identifying conditions that may not be immediately apparent through visual examination alone, thus informing the overall diagnosis and management of the patient's dental health.
