dc.description.abstractObjectives: Compare in vitro bond strength in dentin of three universal adhesive system: Scotchbond UniversalTM (3M ESPE), Peak Univerisal Bond (Ultradent), Tetric N-Bond (Ivoclar Vivadent) through the shear bond. Materials and methods: 75 crowns teeth were selected and cut to this study. Exposed dentin with granulation 220 sandpaper. Subsequently, the crowns were distributed randomly (n=25) and included in databases acrylic 15 x 10mm. The distribution of the groups was G1: System universal Scotchbond™ adhesive Universal (3M ESPE - USA); G2: System universal adhesive Peak Bond Universal (Ultradent); G3: Universal adhesive system Tetric N-Bond (Ivoclar Vivadent). Then, was to make the adhesive phase according to each group and the restorative procedures with composite resin Filtek™ Z350XT-A2 (3M ESPE-USA), according to the manufacturer's instructions. It was made of tygon composite resin (0.79mm x 1.5 mm). The samples were stored in an incubator at 37°C (+/-5 °C) for 24 hours. Subsequently, each group shear test was conducted (0.5 mm / min, 500N load), obtaining values in kg/m2 to convert MPa. Also assessed the type of failure, using a digital microscope of increasing x 200. Oneway ANOVA test was used for statistical analysis between the adhesive strength and universal adhesive systems. Results: No Found statistically significant differences between the systems evaluated universal adhesives Scotchbond™ Universal (14.91±4.76), Peak Bond Universal (16.90±4.11) and Tetric N-Bond (Ivoclar Vivadent) (17.34±4.04) / p-value (p = 0.114). Conclusions: No differences between the values of adhesive strength of three universal adhesive systems used in this study.

html.description.abstractObjetivo : Comparar in vitro la resistencia adhesiva en dentina de tres sistemas adhesivos universales: Scotchbond™ Universal (3M ESPE), Peak Universal Bond (Ultradent), Tetric N-Bond (Ivoclar Vivadent) mediante el test de cizallamiento. Materiales y métodos : 75 dientes bovinos fueron seleccionadas y cortadas. Se expuso dentina con una lija de granulación 220 y las coronas fueron incluidas en bases de acrílico transparente (15x10mm). Se distribuyó aleatoriamente en 3 grupos (n=25): G1-Sistema adhesivo universal Scotchbond™ Universal (3M ESPE-USA); G2- Sistema adhesivo universal Peak Universal Bond (Ultradent); G3- Sistema adhesivo universal Tetric N-Bond (Ivoclar Vivadent). Los procedimientos adhesivos se realizaron según las indicaciones de cada fabricante y los procedimientos restauradores fue realizada con microcilindros (matrices tipo tygon 0,79 x 1,5 mm) de resina compuesta Filtek™ Z350XT-A2 (3M ESPE-USA). Las muestras fueron almacenadas en una estufa a 37°C (+/- 5ºC) por 24 horas. Se evaluó la resistencia adhesiva en una máquina de ensayo universal mediante el test de cizallamiento (0,5 mm/ min, 500N) y el tipo de fractura resultante fue evaluada con un microscopio digital Dinolite (x200). Los resultados fueron analizados mediante estadística descriptiva univariado y bivariada inferencial por el Test de Anova oneway. Resultados: No se encontraron diferencias estadísticamente significativas entre los sistemas adhesivos universales evaluados Scotchbond™ Universal (14.91±4.76), Peak Universal Bond (16.90±4.11) y Tetric N-Bond (Ivoclar Vivadent) (17.34±4.04) / (p = 0.114). Conclusiones : No existen diferencias entre los valores de resistencia adhesiva de los tres sistemas adhesivos universales utilizados en el estudio.
