Introduction and Substantiation of the TopicPrevention of dental diseases should become the main direction of development of modern dentistry. Dental Wear and CariesDental wear and caries are not necessarily a harmful acquisition of civilization. Teeth work at the forefront of life in extreme conditions, withstanding colossal changes in temperature, aggressive influences and pressures. In fact, they work in roughly the same conditions as abrasive cutting edges, car tires, shoe soles and other wear&tear parts. In evolution period when the human body was formed by Nature, only two changes of teeth (milk and permanent) were enough -for in prehistoric times a person lived ARTICLE INFO ABSTRACTThe work is compiled from preclinical studies on volunteers, with the assistance of consultants from dental clinics. It is shown that the topic of preventive and preclinical (extra-clinical) dental care has not been developed (despite the progress in practical prosthetic and filling dentistry). a) In the introduction, the rationale for the need for such work is presented, with an emphasis on the natural basis of the processes of self-restoration of teeth. The authors draw broad analogies with self-restoration in technical (construction, road, auto, air), medical (self-medication / prevention of suppuration and small scratches), and other areas. b) Theoretical assumptions and views on the processes of self-restoration of carious, traumatic and other dental lesions are presented. Methods for creating tooth powders from public&cheap components are proposed for use by non-specialists in places unsuitable for traditional treatment & prophylaxis. c) All these assumptions and hypotheses were confirmed in the results of observations as the well-being of patients as with visual information (photo, X-ray images) of the treated groups of affected teeth.d) The conclusions made confirm the possibility of effective prophylaxis and selfrestoration of dental systems by non-operational exposure to special complexes of dental powders, pastes and rinsing systems (in compliance with the correct teeth's exploitation).

The work is devoted to the study of a new type of composites for the manufacture of special details, parts, tools or adhesive repair in the field. We have developed epoxy compounds that preserve or increase strength and ductility after heating at 200-250oC. That let, if necessary, an effective thermo-disinfection of composite toolsproducts at elevated temperatures. It is believed that conventional epoxy resins are unable to retain their physical and mechanical properties after heating above 200°C. Their feature is in simplicity of making (ordinary filling with available\cheap microfillers) without special qualification of personnel and in any conditions (outside clinics, laboratories and service centers). In this work some of such compositions (with SiC, TiN, SiO 2 -marshalite, cement) are considered. It offers to name such composites of "thermo-harden" or "thermo-plasticized". Bioneutrality, durability and heat-resistance, at 200-300 о С does him a good material for rapid repair and making of the special or failing instruments in the field, travelling, military and other difficult terms.

The possibility of producing composites with 15-80 wt% micronano Basalt Fiber (BF), characterized by several enhanced strength characteristics and higher chemical and fire resistance, was experimentally shown. It is shown that at medium concentrations (15 cpm%) the properties of the composite slightly differ from the unfilled polymer (H-polymer). However, at 50 wt% and especially 80 wt%, serious changes in properties are observed, reflecting a profound change in morphology.
