Laser speckle contrast imaging (LSCI) has been shown to be capable of monitoring the microcirculation as it offers a two-dimensional map of blood flow with high spatial resolution. Progression and the healing of diseases in connection with microcirculation such as periodontitis, and surgical interventions in the oral cavity such as implant placement, involves substantial anatomical reorganization of the affected tissue. Only techniques capable of capturing the 2-D heterogeneity of blood flow changes are suitable for follow up. LSCI has the capacity to do so over an entire mucosal surface in a non-invasive manner without having contact with the surface of the tissue.
Laser Doppler Perfusion Monitoring has also been shown to be a powerful technique for measuring gingival and pulpal blood flow. The implementation of LDF in dentistry is still low, but it is in fact, the most studied and well-documented method for registration of pulpal blood flow1H.J.J. Roeykens, R.J.G.
