An increased response to a vitality test indicates what condition?

• A. Pulp necrosis
• B. Pulpitis with calcification
• C. Normal vitality
• D. Early pulpitis

Answer: (D)

Inflammation makes the nerve fibers in the dental pulp more excitable. When a vitality test is applied, a tooth with early, reversible pulpitis will show an exaggerated response because the inflamed pulp has lowered nerve thresholds and heightened sensitivity. The pulp is still alive, so the response is present and typically more pronounced than normal, but it hasn’t progressed to necrosis. In contrast, a necrotic pulp would show little or no response, a normal pulp would produce a typical response, and calcification can blunt the response.
