Although TiHA reportedly restricts the growth of planktonic bacteria upon ultraviolet A (UVA) irradiation, the antimicrobial effect of TiHA on bacterial biofilms remains to be elucidated. Resin specimens were prepared by adding TiHA to polymethyl methacrylate-based, denture base resin. The specimens were incubated with biofilm-forming Streptococcus sanguinis, Actinomyces naeslundii, Staphylococcus aureus, Escherichia coli, or bacteria from the human saliva obtained from volunteers. After UVA irradiation, the colony-forming units (CFUs) from the biofilms formed on the specimens were determined. CFU numbers for S. sanguinis, A. naeslundii, and S. aureus that formed biofilms on TiHA-containing specimens were significantly lower than those formed on specimens without TiHA. TiHA did not reduce the CFUs of biofilm-forming E. coli. In all cases, CFU numbers in the biofilms formed on TiHA-containing specimens by the salivary bacteria were significantly reduced. In addition, neither a 56 h UVA irradiation nor a 28 d soaking in water diminished the antibacterial effect of TiHA. TiHA in denture base resin exerts an antimicrobial effect on single-species bacterial biofilms and biofilms formed by a wide variety of bacteria from human saliva.","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第833号"}]},"item_10006_version_type_18":{"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_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":"佐藤, 航"},{"creatorName":"サトウ, ワタル","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"586","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sato, Wataru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"589","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":"2019-08-08"}],"displaytype":"detail","filename":"kou_833_txt.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"学位論文","url":"https://osaka-dent.repo.nii.ac.jp/record/205/files/kou_833_txt.pdf"},"version_id":"5af855a5-ad5c-4681-bedf-df8077cf8a5b"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-05-17"}],"displaytype":"detail","filename":"kou_833.pdf","filesize":[{"value":"193.0 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"論文内容要旨・審査結果要旨","url":"https://osaka-dent.repo.nii.ac.jp/record/205/files/kou_833.pdf"},"version_id":"c9f24e16-3f03-4c50-8637-eb20e984feaf"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"titanium hydroxyapatite｜photocatalyst｜bacterial biofilms｜antimicrobial effect｜denture","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":"Antimicrobial Effect of Titanium Hydroxyapatite in Denture Base Resin","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Antimicrobial Effect of Titanium Hydroxyapatite in Denture Base Resin"}]},"item_type_id":"10006","owner":"16","path":["39"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-05-17"},"publish_date":"2019-05-17","publish_status":"0","recid":"205","relation_version_is_last":true,"title":["Antimicrobial Effect of Titanium Hydroxyapatite in Denture Base Resin"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-05-15T15:23:14.486710+00:00"}
