Pulp Vitality Test
Laser Doppler is considered more reliable than sensory testing for pulp vitality testing. This is because there can be adequate vascularisation to support tooth pulp vitality even when sensation is lost due to nerve damage. Blood flow is assessed by placing laser Doppler probes in contact with the teeth, typically using a dental putty splint to support the probe.
The graph below illustrates a simultaneous comparison of blood flow in Vital and Non Vital teeth. Further confirmation can be obtained by using FFT analyses of the blood flow recording to investigate the presence or absence of the cardiac pulse.
