Dental pulp test (DPT) or Pulp sensibility testing is a technique in dentistry used to diagnose pulpal health of a tooth. It is a useful and essential diagnostic aid in endodontics. Pulp sensibility testing can be done by either thermal or electrical means in order to assess pulp health according to the sensory response.[1] Pulp sensibility testing should not be confused with pulp vitality tests, like laser Doppler flowmetry and pulse oximetry, which assess the presence or absence of blood flow within dental pulp.[2]
