Abstract

Introduction: The purpose of this study was to compare the superiority of root fillings made with three different sealers after minimal instrumentation of maxillary Second Molar root canals utilising a modified single-cone method. The specimens were separated into three groups and filled with a size-fit gutta-percha master cone and Sealmax-R (MAARC), Ah Plus (Dentsply), and MTA Plus (PrevestDenpro) sealers. Before and after instrumentation, post-Gentle Wave, and after obturation, micro–computed tomographic images were collected. Starting at the top of the root, the mesiobuccal roots of the selected teeth were sectioned in 0.5-mm intervals. Light microscope was used to examine the cross sections. Results: In all three groups, was filled to 90%–99% of the canal space. Sealmax-R and Ah Plus groups used more filler material on average than MTA Plus group (P <.05). Apical, middle, and coronal thirds showed no significant differences. Cross-sectional scans indicated no obvious gaps in the Sealmax-R groups. After instrumentation, hard tissue debris was discovered in the root canal system in 49 of the 189 canal thirds (25.9%). After Gentle Wave cleaning, only 4 of 63 canals (6.3%) and 4 of 189 canal thirds (2.1%) contained debris.
