What is the function of an Electrical Vitalometer?

• A. To test the color of vital teeth
• B. Check response to electrical stimulus
• C. Measure tooth density
• D. Detect structural integrity

Answer: (B)

An Electrical Vitalometer is designed to check the response of the dental pulp to electrical stimuli, which helps determine whether a tooth is vital (alive) or non-vital (dead). This device is particularly essential in endodontics, where understanding the vitality of a tooth can influence the treatment plan. When a small electrical current is applied through the tooth, the reaction—if any—from the pulp indicates its health. A vital tooth will typically respond, while a non-vital tooth will not show any response, providing crucial diagnostic information for dental professionals.

The other options focus on different aspects of dental assessment that are not the primary role of a Vitalometer. For instance, testing the color of vital teeth does not assess pulp response, measuring tooth density is unrelated to vitality, and detecting structural integrity pertains to physical evaluation rather than pulpal health.
