Resumen

The objective of this study was to evaluate the influence of different speeds using the piston device in the shear bond strength. 48 cylinders of composed resin had been confectioned (Solidex),and were divided randomly in four groups (n=12).  The specimens were adapted to the device for the  shear bond strenth test and were taken to an universal testing machine with a load cell of 1000Kg. The test were carried through with four different speeds: group A: 0,5; group B: 1,0; group C: 1,5 and group D: 2,0mm/min. The mean and standard deviations, in Kgf, were: A - 66,31(10,24); B - 64,53 (20,40); C - 75,23 (11,84) and D - 66,62 (13,81). The data were submitted to ANOVA (p=0,13). The results indicated that it did not have statistical significant difference between the groups   A, B, C and D concluding that the speed in this type of test, with this device, can be varied without modify results.
