Abstract
© (2014) Trans Tech Publications, Switzerland. To investigate the effect of thermocycling on the shear bond strength of the three nomixed bonding adhesive. One hundred and twenty human premolar teeth attached with metal bracket were used in this study. Brackets were bonded to the teeth with three commercial no -mixed bonding adhesive, namely System1+, Rely-a-bond and Unite, 40 teeth for each adhesive group. Each group was divided into two subgroups, one for testing the initial shear bond strength and another at 24 hours after thermocycling following the procedure of adhesive. The three-point bending test was performed to test the shear bond strength of each condition. Descriptive analysis was used to calculate the shear bond strength and One-way ANOVA was evaluated the difference between each subgroup. The data of shear bond strength were tested for normality by Kolmogorov-Smirnov method. Differences between the groups were then evaluated by One-way ANOVA and a Scheffe’s multiple comparison test. Significant difference (p<0.05) of initial shear bond strength were found between each other of three no-mixed adhesive. The shear bond strength of each adhesive after thermocycling was significantly different (p<0.05) and higher than the initial shear bond strength of each adhesive. The shear bond strength of no-mixed adhesive after thermocycling was higher than the initial shear bond strength.
