Abstract
Relevance. The strength of the adhesive system is determined by the type of adhesive system. The choice of the ideal adhesive material remains an urgent task to this day. Objective. Laboratory study of adhesive shear strength of metal bracket systems. Materials and methods. For the preparation of samples, teeth removed according to indications without carious damage and large fillings were used. The samples of 120 teeth were divided into 2 groups (N=60): using a desensitizer and without a desensitizer. In each group, the adhesive shear strength was studied before and after thermal cycling (N=15). The following materials were used: two-component self-curing dental adhesive system Universal Bond Ⅱ (Tokuyama Dental), desensitizer SHIELD FORCE PLUS (Tokuyama Dental), adhesive fixing cement double curing ESTECEM Ⅱ PLUS (Tokuyama Dental). Tests of the adhesive shear strength of the prepared samples were carried out on a universal testing machine "SYNTHEZ 5" at a traverse speed of 5 mm/min according to the methodology of GOST R 56924-2016 (item 7.15). Results . The adhesive strength index of the control group (before thermal cycling) was 4.10 ±0.96 MPa, in the main subgroup (after thermal cycling) 3.44 ±1.03 MPa. The presence of desensitizer on the enamel surface did not affect the adhesive strength of the bonding of the bracket system and tooth tissue and amounted to 3.71 ±0.61 MPa and 2.58 ±0.76 MPa, respectively (p= 0.0005 ). Conclusions. The presence of desensitizer on the enamel surface did not affect the adhesive strength of the connection of braces with tooth tissues in the control (before thermal cycling) and main (after thermal cycling) subgroups (p ⩽ 0.05 ) . The adhesive strength index in the control subgroups (before thermal cycling) and the main ones (after thermal cycling) of both groups differed slightly. Thermal cycling reduces the adhesive strength of braces with tooth tissues when using universal adhesive Universal Bond Ⅱ (Tokuyama Dental) (p ⩽ 0.05).
