Comparative characteristics of the strength of adhesive systems of the fifth generation in the modification of the adhesive protocol

Abstract

The main criterion for effective treatment in dental practice is the adhesive strength of materials. In our days high-quality fixation of materials achieved by the evolution of adhesive systems. Despite the fact that adhesive systems are developing rapidly each generation has a number of advantages and disadvantages that need to be worked on. The issue of optimizing adhesive systems is not completely understood and requires further study and improvement.Aim. The assessment of composite material adhesion strength with tooth hard tissues depending on the adhesive protocol used.Materials and methods. In preparation for the experimental study the teeth were randomly divided into 2 equal groups according to the number of adhesive protocols used. Group 1 samples were processed according to protocol 1 using a moisturizing agent. The samples of group 2 were processed according to protocol 2 using an antiseptic liquid. A sample of the adhesive compound «composite material – tooth» was placed in distilled water and kept in a thermostat at a temperature of (37,0±1,0) Celsius for 24 hours. Tests of the adhesive shear strength of prepared samples were carried out on the testing machine «SYNTHEZ 5».Conclusion. Preparation of the tooth hard tissues surface before restoration using various adhesive protocols is essential and affects the quality as well as the long-term of restoration. The introduction of a moisturizing or antiseptic liquid into the adhesive protocol increases the strength of adhesion.
