After the crowns were resected, patency was established with K-file #15. After working lengths for the subject teeth were determined, glide paths were confirmed using K-file #20. Then canal roots were shaped with the SAF system set at 3,000 vibrations/min or 5,000 vibrations/min using 3% sodium hypochlorite solution or weak alkaline 3% EDTA solution as irrigation fluid and distilled water as control. Status of decalcified dentin was then examined by nano indentation testing and the effect on the removal of dentin smear layer in the apical portion of the root canal was assessed with a scanning electron microscope. Results: No statistically significant difference was found in each item of indentation hardness (HIT), Martens hardness (HM), and indentation modulus (EIT) of the decalcified dentin between respective groups. Additionally, the SAF system showed significantly higher effect on the removal of dentin smear layer in the root canal at both 3,000 vibrations/min and 5,000 vibrations/min in EDTA group compared with sodium hypochlorite solution and control groups. Conclusion: The combined use of the SAF system and EDTA solution demonstrated no significant difference in the effect on the decalcification of dentin smear layer in the root canal compared with control groups. In addition, it was demonstrated that the SAF system exerts effect on the removal of dentin smear layer in the apical portion of the root canal, for which root canal irrigation is challenging, at both 3,000 vibrations/min and 5,000 vibrations/min.","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第491号"}]},"item_10006_heading_21":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_headline":"PDF/A","subitem_heading_language":"ja"}]},"item_10006_publisher_5":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"特定非営利活動法人
