Abstract


espanolEl proposito de este estudio es evaluar el efecto del termociclaje en el cambio de color de los cementos de resina de doble curado sin aminas. Los bloques IPS e.max CAD se cortaron en muestras de 1 mm de espesor (N=28) y se cementaron con uno de los 4 diferentes cementos de resina de curado doble libres de aminas (NX3 Nexus [NX], Kerr Dental; Variolink Esthetic DC [VE], Ivoclar Vivadent; Panavia V5 [PV], Kuraray Dental; G-CEM Linkforce [GC], GC Corporation) (n=7). Se uso un espectrofotometro para las mediciones de color. Las muestras se sometieron a termociclaje (5°C y 55°C; 5000 y 10000 ciclos). La normalidad de la distribucion de datos se probo utilizando la prueba de Kolmogorov-Smirnov. El analisis estadistico se realizo mediante un analisis de varianza de dos vias (ANOVA) y las pruebas de comparacion multiple de Tukey a un nivel de significacion de p0.05). No hubo diferencias estadisticamente significativas entre los valoresn∆E0 y ∆E1 del grupo GC, no obstante, los otros grupos se vieron afectados despues de 10000 termociclos (p>0.05). Cementos de resina libres de aminas. utilizados para la cementacion mostro cambio de color despues del termociclaje, excepto el grupo GC. Todos los cementos de resina mostraron un cambio de color clinicamente aceptable despues del termociclaje (∆E EnglishThe purpose of this study is to evaluate the effect of thermocycling on the color change of the amine-free dual-cure resin cements. IPS e.max CAD blocs were cut into specimens of 1 mm thickness (N=28) and cemented with one of the 4 different amine-free dual-cure resin cements (NX3 Nexus [NX], Kerr Dental; Variolink Esthetic DC [VE], Ivoclar Vivadent; Panavia V5 [PV], Kuraray Dental; G-CEM Linkforce [GC], GC Corporation) (n=7). A spectrophotometer was used for color measurements. Specimens were subjected to thermocycling (5°C and 55°C; 5000 and 10000 cycles). Normality of data distribution was tested by using the Kolmogorov-Smirnov test. Statistical analysis was performed using a two-way analysis of variance (ANOVA) and Tukey’s multiple comparison tests at a significance level of p0.05). There were no statistically significant differences between the ∆E0 and ∆E1 values of the GC group, however the other groups were affected after 10000 thermocycling (p>0.05). Amine-free resin cements used for cementation showed color change after thermocycling except GC group. All resin cements were showed clinically acceptable color change after thermocycling (∆E
