The following results were obtained. 1) The largest number of root canals is seen in the maxillary first molar, followed by the maxillary second molar, mandibular first molar and mandibular second molar in this order. The large number of marrow canals and apical ramification in the mandibular second molar, followed by the maxillary first molar, complicates determination of the number of root canals in these teeth. 2) The number of root canal in the mandibular first molar is larger in the Japanese than in the Swiss. This may indicate the difference among different races. 3) The number of root canals in the maxillary first molar is larger in Japanese than in Swiss populations. 4) The mandibular second molar shows the most complex C-shaped root canal, which increases difficulty of treatment.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"松本歯科大学学会"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00232590","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0385-1613","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"恩田, 千爾"},{"creatorName":"正木, 岳馬"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2012-05-24"}],"displaytype":"detail","filename":"matsumoto_shigaku_24-02-01.pdf","filesize":[{"value":"1.7 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"matsumoto_shigaku_24-02-01.pdf","url":"https://mdu.repo.nii.ac.jp/record/728/files/matsumoto_shigaku_24-02-01.pdf"},"version_id":"4c9429f4-a7e6-4016-ad56-de99b65dbf92"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"大臼歯","subitem_subject_scheme":"Other"},{"subitem_subject":"根管","subitem_subject_scheme":"Other"},{"subitem_subject":"管外側枝","subitem_subject_scheme":"Other"},{"subitem_subject":"根端分岐","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"大臼歯の根管の解剖","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"大臼歯の根管の解剖"}]},"item_type_id":"2","owner":"3","path":["104"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-24"},"publish_date":"2012-05-24","publish_status":"0","recid":"728","relation_version_is_last":true,"title":["大臼歯の根管の解剖"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T08:31:30.441752+00:00"}
