摘要: The aim of this study was to measure root-dentin microhardness after instrumentation with two types files and using irrigation 2.5% sodium hypochlorite. Thirty roots were instrumented irrigation: 10 had the pulp extirpated only; stainless steel files, rotary nickel-titanium (NiTi) files. Additionally, five only without served as a control. sliced determined at depths 500 μm 1000 from pulp-dentin interface. Significant differences found between (p
