Abstract | AIM: The aim of this study was to in vitro evaluate the apical sealability of mineral trioxide aggregate ( MTA) when used as an orthograde root filling material, and to evaluate whether smear layer removal has any influence on the apical seal of this material. MATERIALS AND METHODS: Forty single-rooted human mandibular premolars were selected in this in vitro study. The selected teeth were randomly divided into two equal groups (n = 20) based on the irrigation type. Group 1 was irrigated using distilled water to keep the smear layer intact, and group 2 was irrigated using NaOCl 5.25% and ethylenediaminetetraacetic acid ( EDTA) 17% to remove the smear layer. All teeth were instrumented using a step-back technique and obturated using white MTA. Microleakage of 0.2% rhodamine B solution at the tooth-material interface was evaluated to assess the apical seal of MTA. The data were analyzed statistically using Mann-Whitney test U-test (p = 0.05). RESULTS: When the smear layer was present, MTA revealed less leakage compared to the group of MTA without smear layer with statistically significant difference (p <0.05). CONCLUSION: CLINICAL SIGNIFICANCE: Using white MTA material for the obturation of root canals is a useful procedure. It could be done without complexity in irrigation during root canal treatment and cause no discoloration to the teeth.
