Resistencia a la fractura ante fuerzas compresivas en láminas de G-CAM Grafeno y Vita Enamic. Comparación in vitro

Abstract

The loss of dental structure is due to various factors such as trauma, caries, iatrogenesis generating wear of the tooth structure, being solved with different restorative procedures, a fundamental reason why suitable materials are sought to restore aesthetics and mainly function. Objective To evaluate the compressive resistance to fracture in G-CAM Graphene and Vita Enamic sheets. Materials and methods An in vitro test was carried out, where there was more than one comparison group, characterized by the intervention in group 0 and in group 1 a total of 40 slides were used, 20 for group 0: G-CAM Graphene and 20 for group 1: Vita Enamic. Variables such as: material, resistance, time, and fracture were evaluated. The data were entered in the Excel ® software and analyzed in Stata 14 ® with a descriptive analysis of the variables, through proportions, frequency measures, central tendency, and dispersion, finally the distribution of the data was evaluated using the Shapiro Wilk W test. Results They showed a global mean of the two compared groups of 1.26 [± 0.54] Nw (7.53 [± 3.25] MPa), with a mean global time of occurrence of the fracture 1.01 [ ± 0.49] in Minutes (61.0 [± 29.9] Sec). For G-CAM Graphene the maximum resistance to fracture was 1.67 [± 0.41] Nw (9.95 [± 2.46] MPa), with an occurrence time of 1.2 [± 0, 53] in Minutes (77.58 [± 32.37] Sec). For the Vita Enamic, the value recorded in maximum resistance to fracture was 0.85 [± 0.30] Nw (5.11 [± 1.81] MPa), with an occurrence time of 0.73 [± 0, 24] in Minutes (44.20 [± 14.47] Sec). Conclusions The compressive resistance to fracture between the G-CAM Graphene and Vita Enamic sheets showed statistically significant differences, with G-CAM Graphene being superior.
