FIELD: medicine.;SUBSTANCE: method involves recording dental pulp blood vessels rheodendogram and determining vascular tone index value. Patient electrocardiogram is recorded during the whole dental treatment course before and after tooth odontopreparation concurrently with dental pulp blood vessels rheodentogram recording. Parasympathetic division of nervous system activity index is measured. Vascular tone index ratio with respect to parasympathetic division of nervous system activity index value is determined. The value is compared to a reference value corresponding to its value measured before carrying out odontopreparation. The received value deviating from norm and being not greater than 30%, inflammation process progress in dental pulp is considered to be the case and removal of tooth pulp is advised.;EFFECT: high accuracy and information capacity of evaluation results.;1 tbl
