OBJECTIVE: This study aimed to conduct a comparative evaluation of the shear bond strength of etch and rinse (Single Bond 2), two-step self-etch (Clearfil SE) and one-step self-etch (Go Bond SDI and G-Premio Bond) bonding agents applied to primary teeth, using a universal testing machine.
MATERIAL AND METHODS: The sample was divided into four groups: Group A incorporated Single Bond 2, Group B constituted Clearfil SE, Group C constituted Go Bond SDI, and Group D constituted G-Premio Bond. In each group, 14 out of the total 56 primary canine teeth were considered. Composite restoration was performed using the identified bonding agents on the exposed dentin. A universal testing device was used to evaluate the shear bond strength of the samples. An ANOVA test was used to statistically analyze the obtained data.
RESULTS: By using Kruskal-Wallis test, and determining 0.0080 as the level of significance, shear bond strength with mean standard deviation (SD) was 44.76 ± 32.49 MPa, 92.87 ± 48.63 MPa, 18.55 ± 14.08 MPa, and 22.65 ± 7.74 for Single Bond 2, Clearfil SE, Go Bond SDI, and G-Premio Bond, respectively. Maximum shear bond strength was found in the two-step self-etch bonding agent.
CONCLUSION: Since dentin is involved in most of pediatric caries, especially in rampant caries, providing an appropriate bond has a great impact on a successful restoration treatment. Considering our results, two-step self-etch bonding agent (Clearfil SE bond) demonstrated superior shear bond strength in dentin of anterior primary teeth, over Single Bond 2, Go Bond SDI, and G-Premio bonds. To establish a correlation among various factors affecting bond efficacy, further in vitro and clinical investigations are necessary.
