Comparative evaluation of the apical sealing ability among different root canal obturation techniques and endodontic sealers by using fluid filtration method: A systematic review

Introduction: The target of many experimental studies was to appraise the sealing ability of the root canal filling materials. No systematic reviews are available to appraise such condition. The aim of current review is to appraise the sealing ability of different root canal obturation techniques and sealers using fluid filtration method. Materials and Methods: Two automated databases (Google Scholar and PubMed using English-language literature) were used for this systematic review, using specific keywords together with inclusion & exclusion standards. In December 2018, such investigation was carried out & in March 2019, it was updated. Results: Search detected twelve studies that achieved the present inclusion and exclusion criteria. These studies illustrated different aspects of apical sealing, including: sealing ability, obturation techniques, sealer types, and updating studies in fluid filtration evaluation method. Conclusions: AH Plus had the best sealing ability over all sealers with different obturation techniques when evaluated by fluid filtration device and more investigations should be performed regarding that.
