The aim of this study was to examine if laser Doppler flowmetry (LDF) could aid in distinguishing teeth with necrotic pulps from vital teeth and if so, which configuration of 5 experimental probes would give the best results. Each probe had 3 fibers arranged in a triangle. One fiber carried the laser light to the pulp tissue and 2 fibers carried the back-scattered light to the detector giving the output signal. The distance between the 3 fibers in the triangular arrangement in each probe was 250, 500, 800, 1000, and 1500 microns...
