National Dental Assisting Examining Board (NDAEB) Practice Exam

Topical anesthetics should be applied prior to which procedure to assist with patient comfort?

1. Teeth whitening

2. Extraction

3. Pediatric exams

4. Suture removal

The correct answer is: Suture removal

Topical anesthetics are used to numb the surface tissues, providing comfort to patients during various dental procedures. In the context of suture removal, applying a topical anesthetic can help alleviate any discomfort or pain that might occur when the sutures are being pulled from the gums or other oral tissues. This procedure can be sensitive, especially if the area has not completely healed, and using a topical anesthetic ensures that the patient experiences minimal discomfort during the process. While topical anesthetics may also be beneficial in specific situations for other procedures, suture removal is particularly impactful because it directly involves the potential for pain at the site where sutures have integrated with the tissue. The patient may feel tugging or pulling sensations, which can be uncomfortable, hence the relevance of topical anesthesia in improving the experience. Teeth whitening may also cause some sensitivity, but topical anesthetics are generally not used prior to this procedure. Pediatric exams may involve other strategies to help young patients feel comfortable, but topical anesthetics aren't typically necessary. Extraction, being a more invasive procedure, usually requires more profound anesthesia than what a topical agent can provide.
