<strong> </strong> <strong> Background and Aim </strong><strong>: </strong>Determining the best restorative material to decrease microleakage in class V restorations is of great importance in operative dentistry. The aim of this in-vitro study was to evaluate the microleakage of silorane-based composites compared to low shrinkage methacrylate-based composites in class V restorations.
<p> <strong> Materials and Methods : </strong>In this in vitro study, class V cavities were prepared on the buccal and lingual surfaces of 24 human premolars and molars (48 cavities). The specimens were divided into four groups of 6(12 cavities) as follows: group 1 ( LS System Adhesive, Primer & Bond + Filtek P90), group 2 ( Kalore-GC+ Clearfil SE bond ), group 3 ( Clearfil SE bond + Grandio) and group4 ( Clearfil SE bond + Aelite LS Posterior) . All the specimens were thermocycled for 2000 cycles (5-50oC).</p>
<p> The teeth were then immersed in 0.5% basic fuchsin dye for 24 hours at 370C, sectioned and observed under stereomicroscope. Data were analyzed using Kruskal-Wallis and Wilcoxon tests at a P<0.05 level of significance .</p>
<p> <strong> Results </strong><strong>: </strong>There were no significant differences in microleakage among the four groups at the occlusal margin (P>0.05). But, there were statistically significant differences in microleakage between Silorane and Aelite at the gingival margin (P<0.05).</p>
<p> Statistically significant differences were also found in microleakage between occlusal and gingival margins (except for Kalore and Silorane) (P>0.05 )</p>
<p> <strong> Conclusion </strong><strong>: </strong>Silorane was not superior to the conventional low shrinkage methacrylate-based composites except for Aelite in terms of microleakage .</p>
