| Descripción : | The purpose of this cross-sectional study is to evaluate and compare the tensile strength of three different adhesive systems, in indirect restorations cemented with a dual-type resinous cementing agent through the micro tensile adhesive strength test; for which 45 human premolars were used, which were extracted for orthodontic reasons; in which 45 cylinders of composite resin (Grandio VOCO) were placed. We proceeded to divide randomly into three groups of 15 teeth each, applying the three different adhesion systems successively (Bondfix self-etching adhesive system, Futurabond DC Dual Adhesive System, and conventional 2-step Adhesive System). Once the pieces of 1 mm2 surface were cut, a total of 852 samples were obtained, which were subjected to the Microtraction force test in the test machine (OM100 ODEME), recording the results in grams force transforming them to Newtons and later into megapascals until causing the fracture of the piece. Finally, under observation through a Stereoscope, it was possible to observe the type of failure (adhesive-cohesive) in the fracture of the sample. The results obtained were analyzed in the SPSS statistical program by means of ANOVA test, for the determination of significance P, less 0.05; it was evidenced that there are statistically significant differences between the self-etching adhesive system; being superior in dentin compared to the other adhesive systems that were analyzed. |
