Marginal leakage of retrograde filling materials using stereomicroscope: An in vitro study
Year: 2025
Type: article
Abstract: Root-end filling material apical microleakage in ultrasonic retro tip-prepared retro-cavities is of interest to dentists. Hence, 68 entire maxillary second premolars and mandibular premolars with a single root, removed for orthodontic reasons from individuals were selected for this study. A 3 mm apical root-end excision was performed utilizing a diamond disc while, root-end cavities were created utilizing an ultrasonic retro-tip. Four groups of 17 teeth were randomly assigned to receive retrograde cavity repairs with mineral trioxide aggregate (group 1); Biodentine (group 2), total fill bioceramic root repair material (group 3) and resin-modified glass ionomer cement (group 4). It was observed that bioceramic root repair material (0.197±0.341), biodentine (0.256±0.547) and mineral trioxide aggregate (0.814±0.436) exhibited a significantly lesser microleakage than resin-modified glass ionomer cement (1.381±0.743). Thus, the bioceramic root repair material exhibited the least mean microleakage among all the materials that were assessed in this study.
