But these relations are not yet properly understood. In this paper the periodontal ligament of the young dog was observed under the scanning electron microscope and light microscope. Specimens for SEM were fixed with 10% formaldehyde solution and sliced according to the toothaxis. After dehydration, they were dried by the critical point drying apparatus and coated with gold by using ion spattering apparatus. Periodontal ligament apparatus started to form before emergence of tooth into the oral cavity. Before eruption, the tooth germs were enclosed in a bony crypt. The developing periodontal ligament appeared to consist of loose fibers connective tissue. Fibers which subsequently became dentogingival fibers were demonstrable as an organized entity as they coursed coronally, following the outline of the crown. Apically, fibers arising from beneath the tooth, coursed into the periodontal ligament. They were oriented parallel to the long axis of the tooth. Principal fibers seemed to emanate from cementum and the bone surface. These fibers extended from the root and bone surfaces to the intermediate zone. An intermediate plexus was apparent during the tooth eruption but could not observe in the functional stage. It was considered that the fiber bundle provided the force for eruption by pulling the tooth out from the bony crypt or alveolar socket.","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":"鈴木, 和夫"},{"creatorName":"村松, 力"},{"creatorName":"吉沢, 英樹"}],"nameIdentifiers":[{"nameIdentifier":"0","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2012-05-23"}],"displaytype":"detail","filename":"matsumoto_shigaku_06-01-09.pdf","filesize":[{"value":"3.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"matsumoto_shigaku_06-01-09.pdf","url":"https://mdu.repo.nii.ac.jp/record/252/files/matsumoto_shigaku_06-01-09.pdf"},"version_id":"97b71a0e-4bb9-44e2-af77-0aed342dcb3d"}]},"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":"歯の萌出期における歯周靱帯線維の観察","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"歯の萌出期における歯周靱帯線維の観察"}]},"item_type_id":"2","owner":"3","path":["59"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-23"},"publish_date":"2012-05-23","publish_status":"0","recid":"252","relation_version_is_last":true,"title":["歯の萌出期における歯周靱帯線維の観察"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-19T08:42:25.124758+00:00"}
