Comparative Evaluation Of The Apical Sealing Ability Of BioRoot And Ahplus Sealers: An In Vitro Study

Introduction: The aim of this study was to evaluate the ability of BioRoot sealer in preventing the dye penetration and to compare its filing ability with AH Plus sealer. Materials and methods: 50mandibular premolars recently extracted, single-rooted, were selected. The samples were randomly divided in 2 equal groups (n = 25) for obturation: BioRoot sealer (Group 1) and AH Plus sealer (Group 2). Fifteen teeth of each group were prepared formicroleakage evaluation. The teeth were cleared using teeth clearing technique, then the teeth were examined by a stereo microscope (20x magnification) for evaluation of the linear dye penetration at the toothmaterials interface. The other 10 teeth of each group were prepared to evaluate the void percentages at 2 mm from the apex; andin order to observe and analyze the presence of intra-tubule tags. Data were statistically compared by One-way Analysis of Variance test. Results: The results of the statistical analysis showed that there is a significant difference in apicalleakage between groups. The dye penetration in G2 (0.76± 0.66) mm was more than in G1 (0.26± 0.06) mm, suggesting that newly introduced BioRoot sealed the root canal better compared to AH Plus Sealer. No statistical significant difference was found between both sealers concerning the void percentages. SEM analyses showed the absence of intra-tubule tags for the two techniques analyzed at 2 mm from the apex. Conclusion: A new calium cilicate-based root canal filling material (BioRoot) showed a good apical sealing-ability when it was used in a single cone technique comparing to AH Plus sealer in the mandibular premolar with one canal.
