<p>Esthetic demands of patients have led to the introduction of tooth-colored restorations wherecomposite resins are bonded to the enamel using acid etch techniques. Total etch adhesion systems are still considered as the gold standard among bonding systems. However, clinicians have a tendency to use adhesive systems with simpler application procedures. The aim of the present study is to compare the shearbond strength of composite restorations to intact enamel of primary incisors when using different conditioners and adhesive systems.<br>
<span style="color:#FF0000;"><b>Materials and methods:</b></span></p>
<p>This experimental study was conducted in Shiraz University of Medical Sciences. 53 teeth were collected and classified into five groups based on the bonding procedure. After composite buildup, specimens were placed in a universal testing machine with a cross-head speed of 1mm/ min. Inter-group comparison of the shearbond strength to enamel was analyzed employing one-way-ANOVA and Tukey’s post-hoc test. Data were statistically analyzed using SPSS (Version 17, Chicago, IL, USA).<br>
<span style="color:#FF0000;"><b>Results:</b></span></p>
<p>The highest shearbond strength was found in the second (37% phosphoric acid etching + Margin Bond adhesive system) and fifth groups (37% phosphoric acid etch + Tokuyama Bond Force adhesive system), and the lowest bond strength was found in the third group (Tokuyama Bond Force adhesive system alone) (p = 0.00).<br>
<span style="color:#FF0000;"><b>Conclusion:</b></span></p>
<p>Based on the results of the present study, surface pre-treatment with 37% phosphoric acidalong with self-etching adhesive system resulted in increased shearbond strength in vitro. This method can be further studied in clinical settings.</p>
