Surgical intervention might resolve the problem when a persistent lesion at an apical site is related to complexity of the canal anatomy or formation of biofilms. However, considering the prosthodontics concept of crown-to-root ratio, root resection several times is rather uncommon. This is a case report of a patient with chronic apical periodontitis, which did not heal after three endodontic surgeries, but improved after performing root-end resection with retrofilling, using an operative microscope and a biocompatible root-end filling material, mineral trioxide aggregate (MTA). A 59-year-old female patient visited our hospital complaining of percussion/palpation pain and sinus tract around the root apex of the maxillary right central and lateral incisors. She was diagnosed with chronic apical abscesses, and received endodontic treatment, but the lesions did not heal. Therefore, a modern endodontic surgical protocol, which included root-end resection, ultrasonic root-end preparation, and root-end filling with MTA, was performed. The sinus tract disappeared one month after surgery. Moreover, the postoperative radiography showed that the two radiolucent peri-radicular lesions disappeared, indicating that her clinical condition improved.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟歯学会", "subitem_publisher_language": "ja"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00182415", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0385-0153", "subitem_source_identifier_type": "PISSN"}]}, "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": "大倉, 直人", "creatorNameLang": "ja"}, {"creatorName": "Ohkura, Naoto", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "山本, 信一", "creatorNameLang": "ja"}, {"creatorName": "Yamamoto, Shin-ichi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "阿部, 達也", "creatorNameLang": "ja"}, {"creatorName": "Abé, Tatsuya", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "竹内, 亮祐", "creatorNameLang": "ja"}, {"creatorName": "Takeuchi, Ryosuke", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "遠間, 愛子", "creatorNameLang": "ja"}, {"creatorName": "Tohma, Aiko", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "枝並, 直樹", "creatorNameLang": "ja"}, {"creatorName": "Edanami, Naoki", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "吉羽, 永子", "creatorNameLang": "ja"}, {"creatorName": "Yoshiba, Nagako", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "吉羽, 邦彦", "creatorNameLang": "ja"}, {"creatorName": "Yoshiba, Kunihiko", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "野杁, 由一郎", "creatorNameLang": "ja"}, {"creatorName": "Noiri, Yuichiro", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2024-02-13"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "48(1)_29-35.pdf", "filesize": [{"value": "798KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": "798KB", "url": {"objectType": "fulltext", "url": "https://niigata-u.repo.nii.ac.jp/record/2001173/files/48(1)_29-35.pdf"}, "version_id": "0aaa1955-33a7-4af5-8cd6-9d20bdfa6339"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "マイクロスコープ", "subitem_subject_language": "ja", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Microscope", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "再歯根尖切除術", "subitem_subject_language": "ja", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Endodontic re-surgery", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "逆根管治療", "subitem_subject_language": "ja", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Retrograde Endodontics", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "マイクロスコープを用いた再歯根尖切除術の1例", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "マイクロスコープを用いた再歯根尖切除術の1例", "subitem_title_language": "ja"}, {"subitem_title": "Endodontic micro-resurgery : a case report", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "4", "path": ["456", "1707786000197"], "permalink_uri": "http://hdl.handle.net/10191/0002001173", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2024-02-13"}, "publish_date": "2024-02-13", "publish_status": "0", "recid": "2001173", "relation": {}, "relation_version_is_last": true, "title": ["マイクロスコープを用いた再歯根尖切除術の1例"], "weko_shared_id": -1}
