Technical equipment for assessment of dental pulp status

Assessment of dental pulp status is normally undertaken using thermal or electrical tests that indicate the functioning of Aδ nerve fibers. The tests are quick and usually reliable, although nothing is absolute. Newer tests have involved assessment of blood flow, and of these laser Doppler flowmetry has been the most widely used and beneficial to patients particularly after traumatic injury. The high cost of flowmeters and the time‐consuming procedure have limited uptake.
