Experimental, clinical and statistical studies on the effect and connection between the neuro-psychic diseases and the diseases of periodontium have been described and analyzed. Attention is drawn to the effect of the second signal system and stress states and diseases (with psychogenic, emotional character). The mechanism of stress effect is explained by the law of dialectic for unity and struggle of opposites. The possibility of stress states becoming etiological factors or morbid conditions for periodontium diseases is well grounded.
The signs and varieties of the teeth, dentitions and maxillar bones are described that could be used for identification. The anatomic, morphological, physiological and functional signs upon the teeth are so numerous that, according to the formula of submultitudes, their possible combinations are calculated in millions, hence they are strictly individual and unique. By the twins method it has been confirmed that many signs and varieties of the teeth and some dental-jaw anomalies and defects are hereditary, with a rather high predomination of hereditary factors over the factors of environment. It has been established tahat the theoretical problems for identification and differentation the humans by the teeth and dention are rather well and reliably studied and described but for the needs of forensic medicine and criminology specific methods have to be developed.
