National Dental Assisting Examining Board (NDAEB) Practice Exam

Which aspect of a patient's medical history is particularly relevant before using a topical anesthetic?

1. Previous medications

2. History of dental procedures

3. Allergies

4. Current health insurance

The correct answer is: Allergies

The relevance of allergies in a patient's medical history is crucial before using a topical anesthetic. Many topical anesthetics, such as those containing lidocaine or benzocaine, can cause allergic reactions in susceptible individuals. Identifying any known allergies allows the dental professional to avoid using products that could trigger an adverse reaction, ensuring patient safety during dental procedures. Although previous medications, history of dental procedures, and current health insurance may provide valuable information about the patient’s overall health and treatment options, they do not specifically address the immediate safety concerns associated with the use of topical anesthetics.
