Abstract

Introduction: Amalgam and ADHESIVE RESIN CORE with cemented dowels are commonly used to restore endodontically treated teeth. These restorations have widely been studied for their mechanical properties; however, less is known about their sealing ability. In this study, we compared the MICROLEAKAGE of ADHESIVE RESIN CORE buildup (Core Max 11) of amalgam and adhesive in enamel margins and compared it with amalgam.Materials & Methods: In this interventional experimental parallel group study, 30 intact human premolars were randomly selected. Calss V cavities were prepared on the buccal surface of each tooth with occlusal margin in enamel and gingival margin in cementum. Then, the teeth were divided into two groups with 15 teeth. Next, one group was filled with amalgam and another group with CORE Max 11according to manufacturer's instructions. After thermocycling and dye penetration, the teeth were sectioned and MICROLEAKAGE was assessed. Data were analyzed by T-student and paired t tests through SPSS VII with 95% confidence interval.Results: 1. The mean MICROLEAKAGE of occlusal margins (enamel) of ADHESIVE RESIN CORE, CORE Max II (30.84±5.01) was significantly greater than amalgam Oralloy (13.07±3.5) (P=0.001). 2. The mean MICROLEAKAGE of cervical margins (cementum) of CORE Max 11(39.81±4.92) was not significantly different from amalgam (34.56±2.03). However, the mean for CORE Max 11was greater than amalgam (P=0.337). 3. The mean MICROLEAKAGE of cervical margins of amalgam (34.56±2.03) was significantly greater than occlusal margins (13.07±3.50, P=0.001). 4. Mean MICROLEAKAGE of cervical margins (cementum) of ADHESIVE RESIN CORE, CORE Max II (39.81±4.92) was not significantly different from occlusal margins [enamel, (30.8±5.01, P=0.197)].Conclusion: Amalgam restorations especially at enamel have less MICROLEAKAGE than ADHESIVE RESIN COREs (Core Max 11) and the mean micro leakage of enamel margins is less than cementum margins.
