This study aimed to compare Ca2+ and OH- release and in vivo apatite formation of three bioceramic-containing root canal sealers: EndoSequence BC sealer (Endo-BC), MTA Fillapex (MTA-F), and Nishika Canal Sealer BG (N-BG). Materials and methods Polytetrafuoroethylene tubes filled with sealers were immersed in distilled water for 6 and 12 h and for 1, 7, 14, and 28 days to measure Ca2+ and OH- release. Additionally, tubes filled with sealers were implanted in the backs of rats for 28 days, and in vivo apatite formation was analyzed using an electron probe microanalyzer. Results Endo-BC released significantly more Ca2+ than the other sealers at 6 and 12 h and 1 day. Ca2+ release was significantly lower from N-BG than from Endo-BC and MTA-F at 14 and 28 days. OH- release was significantly higher from Endo-BC than from the other sealers throughout the experiment, except at 1 day. OH- release was lower from N-BG than from MTA-F at 6 h and 7 days. Only Endo-BC implants exhibited apatite-like calcium-, phosphorus-, oxygen-, and carbon-rich spherulites and apatite layer-like calcium- and phosphorus-rich, but radiopaque element-free, surface regions. Conclusions Ca2+ and OH- release is ranked as follows: Endo-BC\u003eMTA-F\u003eN-BG. Only Endo-BC demonstrated in vivo apatite formation. Clinical relevance Endo-BC could promote faster periapical healing than MTA-F and N-BG.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_6_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "Clinical Oral Investigations. 2022, 26(2), 1443-1451.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_6_description_53": {"attribute_name": "学位記番号", "attribute_value_mlt": [{"subitem_description": "新大院博(歯)第517号", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_6_dissertation_number_52": {"attribute_name": "学位授与番号", "attribute_value_mlt": [{"subitem_dissertationnumber": "甲第5031号"}]}, "item_6_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "https://doi.org/10.1007/s00784-021-04118-w", "subitem_relation_type_select": "DOI"}}]}, "item_6_rights_15": {"attribute_name": "権利", "attribute_value_mlt": [{"subitem_rights": "© The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2021", "subitem_rights_language": "en"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Ibn Belal, Md Razi Saifullah ", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"date": [{"dateType": "Available", "dateValue": "2022-07-25"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "r3ndk517.pdf", "filesize": [{"value": "2.75MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": "2.75MB", "url": {"label": "本文", "objectType": "fulltext", "url": "https://niigata-u.repo.nii.ac.jp/record/2000647/files/r3ndk517.pdf"}, "version_id": "766973ae-0012-4ebf-b690-06342b9ada41"}, {"date": [{"dateType": "Available", "dateValue": "2022-07-25"}], "displaytype": "detail", "download_preview_message": "", "file_order": 1, "filename": "r3ndk517_a.pdf", "filesize": [{"value": "295KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": "295KB", "url": {"label": "要旨", "objectType": "abstract", "url": "https://niigata-u.repo.nii.ac.jp/record/2000647/files/r3ndk517_a.pdf"}, "version_id": "3983dac7-2e17-4c4d-ad42-61095fb99cec"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Bioceramic-containing root canal sealer", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Apatite-forming ability", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Calcium ion release", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hydroxyl ion release", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Subcutaneous implantation", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Electron probe microanalyzer", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "doctoral thesis", "resourceuri": "http://purl.org/coar/resource_type/c_db06"}]}, "item_title": "Comparison of calcium and hydroxyl ion release ability and in vivo apatite-forming ability of three bioceramic-containing root canal sealers", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Comparison of calcium and hydroxyl ion release ability and in vivo apatite-forming ability of three bioceramic-containing root canal sealers", "subitem_title_language": "en"}, {"subitem_title": "3種のバイオセラミック配合シーラーのカルシウム水酸化物イオン放出能および生体内アパタイト形成能の比較", "subitem_title_language": "ja"}]}, "item_type_id": "6", "owner": "1", "path": ["455", "434"], "permalink_uri": "http://hdl.handle.net/10191/0002000647", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-07-25"}, "publish_date": "2022-07-25", "publish_status": "0", "recid": "2000647", "relation": {}, "relation_version_is_last": true, "title": ["Comparison of calcium and hydroxyl ion release ability and in vivo apatite-forming ability of three bioceramic-containing root canal sealers"], "weko_shared_id": -1}
