A Stereomicroscopic Investigation of the Microleakage of Posterior Teeth Restored with Amalgam, Composite, and Ormocer

Abstract Introduction: In dentistry, various restorative materials are employed to produce sufficient strength and restore esthetics. Dentists have yet to discover the right restorative material. Dental amalgam is a multipurpose material that has self-sealing properties while being unwanted. While they need meticulous preparation, some restorative materials such as composites show microleakage due to polymerization shrinkage. The development of composite materials has improved therapeutic results in terms of both function and appearance, in addition to increasing the range of reasons for their usage. Although their connection to microleakage and polymerization shrinkage has not yet been shown, secondary caries continue to be significant constraints that significantly impact the clinical durability and effectiveness of restorations in spite of these advancements. To address these issues, Ormocer – a newer dental material with inorganic silanated particles was created. Materials and Methods: Thirty was the sample size selected. On the occlusal surface, Class I cavities were made. As directed by the manufacturer, amalgam, composite, and Ormocer were used for restoring the cavities. After being kept in distilled water for a full day, each sample was thermocyclized. A separating medium was applied to the whole tooth surface, extending to external margins approximately 1 mm. Then, the teeth were immersed in dye. Samples of teeth were examined using a stereomicroscope. Results: In this investigation, the Ormocer exhibited the least amount of microleakage when compared to amalgam and composite, although composite showed more microleakage than amalgam. Conclusion: Amalgam continues to be one of the best materials despite the intense marketing of composite and amalgam as well as the emergence of new materials such as Ormocer.
