An in-vitro evaluation of microleakage in methacrylate based flowable composite and resin modified glass ionomer cement in class ii restoration

Aim: The aim and objective of this study is to evaluate the microleakage of methacrylate based flowable composite (SDRTM posterior bulk fill flowable base) and a Resin modified Glass Ionomer Cement (FUJI IITM LC®) at the interface of tooth and the restoration in Class II design.
Subjects and Methods: Ten extracted human maxillary molars were selected for this study. Class II cavities were prepared on both mesial and distal surfaces, making them twenty prepared cavities. These samples were divided into two groups and restored by the two materials respectively (n=10). Following this microleakage of these materials were evaluated by dye penetration under stereomicroscope.
Statistical Analysis: Microleakage values were analyzed using Post- hoc Test (P= 0.05).
Results: SDR shows a good sealing ability (5.9863) to the tooth surface thus minimising the microleakage when compared to the Fuji II LC (5.4223).
Conclusion: Out of the two-materials methacrylate based flowable composite demonstrated less microleakage compared to Resin Modified Glass Ionomer Cement.
