Using a human premolar tooth, a triangular transverse groove was formed on the dentine surface to the mesiodistal direction and cyclic-stress loading was added to break the specimen to measure the stained range of penetrated pigment observed on the broken surface after testing. Next, the broken surface was observed using SEM from a bird's-eye view as well as side sectional view and fractography analysis was done. As a result, the following findings and conclusion were obtained. Results: 1) The fractured region that indicates the starting point of the fracture was clearly detected with silver staining. 2) An irregular structure in a wave-like design existed in the silver stained region on the broken surface. 3) The apical region of the wave-like structure zone was generally even on the broken surface. 4) The apical region of the wave-like structure zone was assumed to be a kind of striation structure peculiar to dentin. Taking the above into consideration, it was indicated that in fractured teeth, cracks occur first by repeated stress then the beginning of the crack is notched to operate as a site of action leading to immediate brittle fracture.","subitem_description_type":"Other"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN1010214X","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Conservative Dentistry Ohu University Graduate School of Dentistry"}]},"item_1_text_2":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_text_value":"原著論文"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Original Article"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"奥羽大学大学院歯学研究科歯科保存学専攻"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2006-03-31"}],"displaytype":"detail","filename":"KJ00004418153.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"url":"https://ohu-lib.repo.nii.ac.jp/record/2483/files/KJ00004418153.pdf"},"version_id":"9f435592-9a54-4666-beb1-ff086f28380d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"starting point of fracture","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"silver staining","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"fractography","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"striation structure","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":"歯の咬合性破壊に関する実験的研究 : 破折起始点の探知法と構造観察について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"歯の咬合性破壊に関する実験的研究 : 破折起始点の探知法と構造観察について"},{"subitem_title":"Experimental Study on Mechanism of the Masticatory Tooth Fracture : Method to Detect Starting Point of Fracture","subitem_title_language":"en"}]},"item_type_id":"1","owner":"3","path":["107"],"pubdate":{"attribute_name":"公開日","attribute_value":"2006-03-31"},"publish_date":"2006-03-31","publish_status":"0","recid":"2483","relation_version_is_last":true,"title":["歯の咬合性破壊に関する実験的研究 : 破折起始点の探知法と構造観察について"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-15T14:50:11.986170+00:00"}
