On a human tooth extracted for medical reasons, a carious cavity of class II according to Black was prepared. Next, conditioning of the hard tissues of the tooth was performed. It was revealed that the conditioner is poorly washed out of the tooth cavity and there is a possibility that phosphoric acid will remain between the matrix system and tooth tissues, it can lead to complications. Then, an adhesive system was applied to the prepared cavity with a microapplicator, which was rubbed strictly according to the instructions, polymerized. On another tooth removed for medical reasons, the filling of the carious cavity of class II according to Black was performed by the self-adhesive fluid composite Vertise Flow according to the technique developed by us. Instead of adhesive and flowable material, the composite was applied on the prepared enamel of the contact surface. In the study of sections revealed that the restoration of the contact surface is made in accordance with the anatomical features of the tooth, with a high-quality edge fit. This demonstrate the effectiveness of filling without adhesive preparation of the contact point. The use of Vertise Flow self-adhesive composite, during restoration of class II according to Black, allows to improve the quality of treatment. Micromechanical retention, as a result of which interpenetration occurs between the polymerized particles of the Vertise Flow composite monomer and the dentin collagen fibers, allows the formation of a diffusion zone and close contact between the material and the enamel surface. This fact allows to eliminate the defect of filling by the absence of an «adhesive side», which occurs under the classical adhesive protocol, thereby making prevention of secondary caries of class II according to Black.</p>self-adhesive compositerecurrent cariespolymerizationocclusal surface of the toothcontact surface of the toothgingivitisprevention of cariesregional depressurization of the tooth cavityсамоадгезивный композитрецидивирующий кариесполимеризацияокклюзионная поверхность зубаконтактная поверхность зубагингивитпрофилактика кариесакраевая разгерметизация полости зуба[Абрамов, А.В.
