Final irrigation protocols may affect intraradicular dentin ultrastructure Objectives The aim of this study was to evaluate the effect of dentin collagen, and enhanced by EDTA and/or PUI, promot- different irrigation protocols on the root dentin structure using ed peritubular and intertubular erosion. Clinical relevance The effect of irrigating solutions on dentin scanning electron microscopy (SEM) and transmission elec- ultrastructure was still unclear. The acknowledgment about tron microscopy (TEM).

After the root halves were reassembled, it without jeopardizing the dentin ultrastructure quality. was applied a specific irrigation protocol for each group, as . . . . following: G1, distilled water (control); G2, 0.9% saline; G3, Keywords Chlorhexidine Dentine EDTA Endodontics saline + 17% EDTA; G4, saline + PUI; G5, saline + PUI + Sodium hypochlorite EDTA; G6 to G9 received the same protocol as above replac- ing 0.9% saline by 2.5% NaOCl; and G10 to G13 by 2% CHX. One-half of each sample was prepared and evaluated Introduction using SEM and the other one by TEM observations. Results TEM Clinical Oral Investigations Springer Journals
