<strong> </strong> <strong> Background and Aim </strong><strong>: </strong>Current self-adhesive resin cements have become popular for esthetic restorations. The purpose of this study was to compare the microleakage of 2 self-adhesive resin cements and 2 etch and rinse versions of the same brands .<strong> </strong>
<p> <strong> Materials and Methods </strong><strong>: </strong>Forty human third molars were randomly assigned to 4 experimental groups: 1-Rely X Unicem, 2- Rely X ARC+ Acid etch 37% + Single Bond ,3- Nexus 3 Acid etch 37% + Optibond Solo, and 4- Maxcem Elite. Microleakage of the specimens were then measured with a four point scoring system at both the cervical &occlusal areas, with the aid of a stereomicroscope. Microleakage scores were compared using Kruskul-Wallis analysis, followed by relative Dunn test .</p>
<p> <strong> Results </strong><strong>: </strong>The microleakage of Rely X Unicem and Nexus 3 were significantly less in the occlusal region (P<0.05), whereas in the cervical area there was no significant difference in microleakage between Rely X Unicem and Rely X ARC (P= 0.0087). The microleakage of Nexus 3 was significantly less than that of Rely X Unicem.Maxcem Elite showed the highestlevel of microleakage (P<0.05 ).</p>
<p> <strong> Conclusion </strong><strong>: </strong>Microleakage of both cements using etch & rinse adhesive systems were significantly lower in comparison withtheir self- etch counterparts both at the cervical &occlusal areas. (P< 0.05 )</p>
