Abstract
Section titled āAbstractāMicroleakage can lead to staining around the margins of restorations postoperative sensitivity secondary caries restoration failure pulpal pathology or pulpal death partial or total loss of restoration. Microleakage is usually associated with invasion from the external environment through the margins of the restoration but microleakage can also occur internally.This study was carried out to evaluate in vitro the microleakage of four different dentin replacement materials ie.Group I - Glass inomer cement Group II - Smart dentin replacement Group III - BiodentineGroup IV - MTA Angelus. On 60 samples class V cavity was prepared using a templete. Restoration was done following standard protocol. All samples were sectioned into two halves in buccolingual direction with a water-cooled slow speed diamond saw using air motor. Sample were viewed under Scanning Electron Microscope (100X) and stereomicroscope (40X).Photomicrographs were evaluated for both total length and adapted margin in mm. All the materials considered in study showed gaps. But the highest marginal adaptability (%) 95.70?1.29 % and least microleakage 0.40?0.51 was shown by Group II followed by Group III 80.13?5.67 %. So that we can say that the group which have maximum marginal adaptability showed least microleakage and vice versa.
