It has been shown that the method of digital dynamic photography 
is an effective technique for quantitative and qualitative diagnosis 
of the microcirculatory state of mouth tissues. As a result of the 
signal processing, one can obtain information on microcirculation 
indices from the spectral distribution of low-frequency variations 
of the speckle structure. The investigated method of digital dynamic 
speckle photography can be used to elucidate the haemodynamic features 
in tissues of the oral cavity even at early stages of the disease 
and then at the examination and treatment stages. New possibilities 
of digital laser speckle technologies for tomographic investigations 
of the near-surface blood flow at various depths with the use of two-lens 
optical configurations are illustrated.
