Abstract

 Introduction: Nowadays, the most commonly used dental materials are resin COMPOSITEs that have a capability of good reconstruction in the anterior part of the mouth. Therefore, the factories producing these materials endeavor to produce materials that in addition to esthetic properties have good adhering and lasting properties in order to prevent MICROLEAKAGEs and recurrent caries. In this study, we compared the micro leakages of two types of resin COMPOSITEs; one Iran made and named Ideal Makoo and another Lichtenstein made and named Heliomolar. Methods: 50 healthy human upper premolars were extracted to perform the mentioned study. Then, class V standard cavities were prepared at the cervical area of facial surface such that the gingival portion was in cementum, while the occlusal portion was in enamel. The teeth were divided into two test groups of 25 teeth each. The first group cavities were filled with Ideal makoo resin COMPOSITE and the second group restored by heliomolar resin COMPOSITE, then finishing and polishing was done. The specimens were then placed in 370C temperature for 8 days and after that, the specimens were thermocyled and placed in 0.5% basic fuchsin solution for 48 hours. After washing, the specimens were sectioned in buccolingual direction and scanned by computer with Photoshop software to calculate MICROLEAKAGE separately in enamel and cementum. The results were analyzed by t, multivariate t, and t 2 Hotling tests. Results: According to tests, the MICROLEAKAGE of enamel using Ideal Makoo resin COMPOSITE was less than heliomolar resin COMPOSITE (P=0.005). Also. the MICROLEAKAGE of cementum in Heliomolar COMPOSITE was significantly less than Ideal Makoo COMPOSITE (P=0.014). Conclusion: This investigation showed that neither Heliomolar nor Ideal-Makoo COMPOSITEs are able to completely eliminate MICROLEAKAGEs in invitro conditions.
