In out popular-scientific experimental publication, for first time, a theoretical substantiation of the need to introduce preventive and self-restorative methods in dentistry was carried out. It is possible due to the use of compositions with nano-silica, nano-aluminum oxide and micro-sized mineral plant fillers. Methods are proposed for creating tooth powders and epoxy polymer fillings — from publicly available components (herbal/mineral powders, epoxy-resin etc), for use by non-specialists in places unsuitable for traditional prevention. All these assumptions and hypotheses found confirmation in the obtained results of observations in the well-being of patients of visual information (photo-, x-ray image) of the treated groups of affected teeth. The experimental part was based on the results of preclinical studies and was performed on volunteers, with the involvement of consultants from dental clinics. The conclusions confirm the possibility of effective prophylaxis and selfhealing of dental systems through non-operative exposure to special complexes of dental powders, pastes and rinse systems (with the correct operation of the teeth).
