The problem of hard dental tissues diseases treatment, the high need of the population to replace poor-quality restorations, as well as the constant dentistry market updating make it necessary to evaluate dental restorations using objective criteria. The purpose of this article is to present the new FDI criteria for evaluating aesthetic restorations and explanations of their use, as well as a quality comparative assessment of restorations made from various light-curing composites. The clinical part of the work was to assess the restoration quality III and IV Black classes. A total of 33 restorations were made. All patients had good oral hygiene (OHIS <0.6±0.02) was characterized by the absence of inflammation or mild inflammation of the gums (GI <0.66±0.04) and high intensity of the carious process (KPU=12.2±0.8). The analysis of the obtained data from the pilot clinical study leads to the following conclusions: new advanced FDI criteria provide complete information about quality of the restorations and can be recommended for evaluating the clinical efficacy of various materials; this evaluation system of restorations is flexible, it can change over time and it allows you to follow the new trends in materials science and restoration methods as accurately as possible.
