- Abstract
Introduction: This study sought to compare the influence of irrigation protocols using different concentrations of Hydroxyethylidene bisphosphonate (HEBP) and sodium hypoclorite (NaOCl) and a protocol using ethylenediaminetetraacetic acid (EDTA) and NaOCl, regarding the penetration of endodontic sealer inside dentinal tubules, and also, to determine the correlation between maximum depth of penetration (MDP) and segment of penetration (SP). Methods: Single-rooted human mandibular premolars (n=33) were distributed in irrigation protocol groups during chemomechanical preparation: P1) combined solution of 9% HEBP and 2.5% NaOCl during instrumentation and at final rinse; P2) 2.5% NaOCl during instrumentation and 18% HEBP followed by 2.5% NaOCl at final rinse; P3) 2.5% NaOCl during instrumentation and 17% EDTA followed by 2.5% NaOCl at final rinse. The root canals were obturated using the single cone obturation technique. The Confocal Laser Scanning Microscopy analysis obtained measurements of MDP and SP. The Kruskal-Wallis test analyzed MDP and SP in each root canal third among the groups (p<0.05). The Pearson's linear correlation analysis associated MDP and SP (p< 0.05). Results: P1 and P2 provided significantly greater MDP than P3 at cervical third; MDP was significantly greater at cervical and middle thirds (p<0.05). SP was significantly greater in P1 and P2 at cervical and middle thirds (p<0.05). There was a significant direct correlation between MDP and SP (p<0.05). Conclusion: Irrigation protocols using HEBP in different concentrations and NaOCl promoted greater endodontic sealer penetration inside dentinal tubules than the protocol using EDTA and NaOCl. MDP and SP are directly correlated.
