Dysphagia, caused by diseases, accidents, or aging, can be a major contributor to a reduced quality of life. Often, only symptomatic therapy options exist for dysphagia. Therefore, to develop improved treatment and prevention methods, a better understanding of the pathophysiology associated with dysphagia is needed.\nObjective: This study aimed to investigate the intercorrelation between mastication and swallowing, specifically focusing on the effect of restricted mastication duration on swallowing function.\nMethods: Thirty healthy men (25±3 years old, mean±SD) were instructed to masticate a gummy jelly for free mastication (G100), half, and one-quarter duration of G100. Masseter and digastric electromyograms (EMGs) were recorded as parameters, representing masticating and swallowing, respectively, along with the velocity of the thyroid cartilage ridge measured with an accelerometer. Masticatory efficiency was evaluated using a glucosensor. The root mean square (RMS) of muscle EMG activity, the number of masticatory cycles, time to peak and total duration of each masticatory cycle, swallowing duration and latency, and masticatory efficiency were analyzed.\nResults: Restricting mastication duration reduced the number of mastication cycles and prolonged the time to peak and total duration of masticatory cycles, which increased masticatory muscle activity. On the other hand, shortened duration and latency of swallowing increased swallowing muscle activity. Consequently, masticatory efficiency decreased.\nConclusion: Under restricted mastication conditions, habitual masticatory patterns could be optimized to achieve safe swallowing in healthy individuals.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第1007号"}]},"item_10006_relation_14":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1111/joor.13799","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"Journal of Oral Rehabilitation. 2024, 51(10), p. 2063-2071."}]}]},"item_10006_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2024 John Wiley & Sons Ltd.","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":"作成者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"林, 浩基","creatorNameLang":"ja"},{"creatorName":"ハヤシ, ヒロキ","creatorNameLang":"ja-Kana"},{"creatorName":"Hayashi, Hiroki","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":"2024-06-01"}],"filename":"kou_1007_ab.pdf","filesize":[{"value":"256 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"論文内容要旨・審査結果要旨","objectType":"abstract","url":"https://osaka-dent.repo.nii.ac.jp/record/2000119/files/kou_1007_ab.pdf"},"version_id":"0a8f28bd-eaf1-4b58-967c-14ea008ba1d7"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-01-31"}],"filename":"kou_1007_txt.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"学位論文","objectType":"fulltext","url":"https://osaka-dent.repo.nii.ac.jp/record/2000119/files/kou_1007_txt.pdf"},"version_id":"ebd156e7-5143-4e38-898d-553db5d932da"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"electromyography","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"masseter muscles","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mastication","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stomatognathic system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"swallowing","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":"Influence of restricted mastication on swallowing function","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Influence of restricted mastication on swallowing function","subitem_title_language":"en"},{"subitem_title":"咀嚼運動の制限が嚥下機能に及ぼす影響","subitem_title_language":"ja"}]},"item_type_id":"10006","owner":"18","path":["65"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-01"},"publish_date":"2024-06-01","publish_status":"0","recid":"2000119","relation_version_is_last":true,"title":["Influence of restricted mastication on swallowing function"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2025-02-02T07:29:06.664408+00:00"}
