Can pulp vitality be determined from a radiograph alone?

• A. Yes
• B. Sometimes
• C. No
• D. Cannot be determined from radiographs alone

Answer: (C)

Radigraphy shows structure and pathology, not the tooth’s function. Pulp vitality is about the living status and responsiveness of the dental pulp, which requires a physiological assessment. A tooth can be vital and still show no radiographic signs, or be non-vital with little or no radiographic change initially. Therefore, you can’t determine pulp vitality from a radiograph alone. Vitality testing—such as responses to thermal or electrical stimuli—along with clinical findings, is needed in conjunction with radiographs. Radiographs can support your assessment by revealing related signs (exposure, caries, periapical changes, resorption, calcifications), but they do not measure vitality themselves.
