What is commonly indicated by a negative pulp vitality test?

• A. Healthy pulp
• B. Necrotic pulp
• C. Inflamed pulp
• D. Normal hydration

Answer: (B)

A negative pulp vitality test typically indicates that the pulp tissue is non-responsive, which is a hallmark of necrotic pulp. When the pulp is alive and healthy, it responds positively to stimuli, such as temperature changes or electrical impulses. However, when the pulp becomes necrotic, it loses its ability to respond to such tests due to the death of nerve fibers and blood supply, leading to a failure to produce any sensation. Thus, a negative result suggests that the pulp may be irreversibly damaged and may require further intervention such as root canal therapy. In contrast, a healthy pulp would elicit a strong positive response during vitality testing, indicating that the nerve and blood supply are intact and functioning properly. Similarly, inflamed pulp may still respond, although possibly with varying sensitivity or pain, reflecting its state of irritation. Normal hydration does not directly relate to vitality tests, as it pertains more to tissue health rather than the functional vitality of pulp tissues.
