[THE STRENGTH OF ADHESION TO HARD TISSUES OF NON-VITAL TEETH OF DENTAL PHOTOCOMPOSITE FILLING (RESTORATIVE) MATERIALS IN COMBINATION WITH VARIOUS ADHESIVE SYSTEMS].

Improvement the mechanisms and levels of adhesion forces of dental photocomposite filling (restorative) materials to hard tissues of teeth, improvement of filling materials and increasing their availability is an urgent problem for theoretical and practical dentistry. Aim of the study - experimental evaluation of the strength of adhesion to the hard tissues of non-vital teeth for adhesive systems in combination with modern dental photocomposite filling (restorative) materials. 80 tests of the adhesion strength of the dental photocomposite filling (restorative) material to the tooth hard tissues (shear strength) were carried out for 8 pairs of "photocomposite-adhesive system" using an automated tensometric system.
