Abstract

Introduction: Bond strength between the restorative material and tooth structure is one of the major factors in the selection of restorative materials, which plays a key role in durable restoration and reducing microleakage. Considering the recent attention of researchers to low-shrinkage composites, the present study aimed to compare the MICRO-SHEAR BOND STRENGTH of silorane-based composite (P90) with the conventional methacrylate-based composite (Z250) to the dentin of primary teeth.Materials and Methods: In this experimental study, 24 intact primary canines were selected. Two disks (thickness: 2 mm) were prepared from each tooth, and the samples were randomly divided into four groups (n=12). Composite resin cylinders (r=0.7) were adapted on each dentin surface, as follows: g1: (silorane bond system+P90), g2: (etch+silorane bond system+P90), g3: (single bond+Z250), g4: (etch+single bond+Z250). Afterwards, the samples were subjected to a MICRO-SHEAR BOND STRENGTH test until failure. Data analysis was performed using Tamhane’s T2 (P<0.05).Results: Statistically significant differences were observed between the four groups of g1, g2, g3, and g4. The highest bond strength was reported in the second group (etch+silorane bond+composite P90), while the third group (single bond+Z250) had the lowest MICRO-SHEAR BOND STRENGTH compared to the other groups.Conclusion: According to the results, silorane-based composite (P90) has higher MICRO-SHEAR BOND STRENGTH to the primary dentin compared to the methacrylate-based composite (Z250). Moreover, etching the surfaces could increase the bonding efficiency of P90 to the primary dentin.
