Comparative Analysis of Shear Bond Strength of Four Adhesive Systems on Primary Dentin

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.
