What is the purpose of pulp vitality testing in dental diagnosis?

• A. To determine whether the tooth pulp is vital or nonvital (dead), guiding treatment decisions.
• B. To measure tooth color.
• C. To assess chewing efficiency.
• D. To determine crown size.

Answer: (A)

Vitality testing checks whether the tooth pulp is alive and capable of a response to stimuli. By using controlled stimuli—like a cold test or an electric pulp test—you determine if the pulp tissue is vital or nonvital. This guides treatment decisions: a responsive, vital pulp may allow pulp-conserving approaches if the inflammation is reversible, while a nonvital pulp often leads to endodontic therapy or extraction. The test focuses on the pulp’s sensory and vascular status, not unrelated factors such as color, chewing efficiency, or crown size.
