Influencia de los humectantes resinosos en la resistencia compresiva de la resina de nanopartículas

RESUME This research project was developed with the objective of evaluating the influence of resinous humectants on the compressive strength of nanoparticle resin, through a bibliographic, descriptive, observational, comparative, in vitro, experimental and cross-sectional study. Thirty 4x4 mm cylindrical specimens of Filtek Z350 XT nanoparticle resin (3M ESPE) were made, equally distributed in three study groups; Group 1: 10 resin specimens without the application of resinous wetting agents, Group 2: 10 resin specimens with Wetting Resin (Ultradent) resinous wetting agent and Group 3: 10 resin specimens with Adper Single Bond 2 (3M ESPE) adhesive as wetting agent. The resin specimens were subjected to mechanical compression forces in the universal testing machine Tinius Olsen model SUPER L 120, of the Laboratory of Stress and Vibration Analysis of the Department of Mechanical Engineering of the National Polytechnic School, obtaining values of maximum compression stress 143.35 MPa for Group 1; 132.40 MPa for Group 2 and 124.36 MPa for Group 3. Through the parametric ANOVA test, it was determined that there are no statistically significant differences (p = 0.546) between the study groups, concluding that the application of resinous moisturizers it does not adversely affect the compressive strength of the nanoparticle resin. Keywords: resinous humectants, compressive strength, nanoparticle resin
