Introduction. Dental aesthetics is a very wide field, which allows each subdomain of the dental medicine to be approached through the aesthetic component.  Aim of the study. Restoration of odontous lesions of different degrees of damage to composite fluids.  Materials and methods. The study was based on the treatment of 20 patients with odontous lesions. Direct dental restorations with CLEARFIL AP-XEstheticsFlow flowable composite materials were performed. The restoration protocol included: oral hygiene; anesthesia when needed; isolation of the field by application of cofferdam; preparation of carious cavity by minimal invasive technique; treatment of dental wound with sol. 0.05% Chlorhexidine; engraving dental tissues (orthophosphoric acid 37%, 15-30 seconds) and removing it with a jet of water; application of bonding and light-curing; restoration with ONE-Shade flowable composite materials; polishing the restoration.  Results. The following study found the benefits of odontous lesion treatments with the use of flowable composite materials by the direct method of restorations using the minimal invasive technique. Patient monitoring was performed (clinically and paraclinically) at 3 months, 6 months and 12 months.  In the treatment of odontous lesions, this protocol was selected using composite materials based on their properties: reduced viscosity (good handling and easy placement); exhibits increased mechanical properties (wear resistance, durability); high radioapacity and very low polymerization shrinkage.  Conclusions. Dental composites are complex restorative materials, but for lasting restorations and very good aesthetic results we must rely on scientific considerations.
