Background and Objective In endodontics, a major diagnostic challenge is the accurate assessment of pulp status. In this study, we designed and characterized a fiber‐based laser speckle imaging system to study pulsatile blood flow in the tooth. Study Design/Materials and Methods To take transillumin...
