Popis: The purpose of this study was to evaluate a new simultaneous activation technique (SAT)-for the union between glass ionomer cements and composite resins.Forty primary molars were embedded in self-curing acrylic resin. Class I cavity preparations were performed on the dentin surface and the teeth were randomly divided into 4 groups (N = 10). Two groups were restored with the SAT and 2 by etching the ionomer surface/sandwich technique (ST). The materials tested were Vidrion F (SS/ White), Vitremer (3M), and Z100 (3M). After 24 hours in aqueous solution at 37 degrees C, a tensile test was performed. The microleakage study was also performed by selecting 40 primary molars which were distributed in the same way as in the bond strength test. Furthermore, 1 tooth from each group of the microleakage test was evaluated by means of scanning electron microscopy.The SAT and ST did not show statistically significant differences in both tests.The SAT is a less complex, quicker, and feasible alternative for the bonding of glass ionomer cements to composite resins in primary molars.
