Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to medicine and namely to preventive and orthopedic dentistry, and can be used to assess the hygienic state of the oral cavity in patients. The surface of all teeth is stained, the surfaces of the upper and lower rows of teeth are photographed after staining, and the index of the hygienic state of the tooth surface is calculated. In this case, photographing of each row is carried out from three angles: from the side of the vestibular, occlusal and oral surfaces. Based on the images obtained, volumetric models of each tooth are formed. The surfaces of the teeth are converted into a planar image, and the hygiene index is calculated using the formula HI = s/S, where s is the total area of the painted surface of the teeth, S is the total surface area of the teeth, or according to the formula HI = sxC av. /S, where s is the total area painted surface of teeth, S is the total surface area of the teeth, and C av.  is the average coefficient of the degree of staining of the tooth surface, defined as   where s i  is the colored area of the tooth surface with a color saturation corresponding to the coefficient i, and S is the total area of the entire tooth surface. 
     EFFECT: method makes it possible, by determining the hygiene index of the entire tooth surface, as well as the hygiene index of each individual tooth, to diagnose both the general condition of the patient's dental surface and each of the individual teeth not related to quality of their cleaning.
