A bovine incisor was cut into enamel blocks. EVA plates containing and lacking S-PRG fillers were formed into eight mouthguards of each type using a thermoplastic material molding device to fit enamel blocks. Mouthguards were attached to each enamel block and immersed in a demineralization solution (37°C, 24 h). The degree of demineralization was assessed by micro-CT. Using the mouthguard lacking S-PRG\\nfiller (control), enamel blocks revealed a major demineralization over a wide area, including areas immediately under the mouthguard, and uncovered areas. In contrast, enamel blocks covered with mouthguards containing S-PRG filler revealed only mild demineralization, both directly under the mouthguard and in uncovered areas. CT values revealed that scores for enamel surfaces at depths from 0 to 252 μm were significantly higher in enamel blocks that were fitted with S-PRG filler mouthguard than in those of the controls (p < 0.05). These results indicate that mouthguards containing S-PRG filler could inhibit demineralization.","subitem_description_type":"Abstract"}]},"item_6_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"学位の種類: 博士（歯学）. 報告番号: 甲第4145号. 学位記番号: 新大院博（歯）甲第343号. 学位授与年月日: 平成28年3月23日","subitem_description_type":"Other"}]},"item_6_description_53":{"attribute_name":"学位記番号","attribute_value_mlt":[{"subitem_description":"新大院博（歯）甲第343号","subitem_description_type":"Other"}]},"item_6_dissertation_number_52":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"13101甲第4145号"}]},"item_6_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"50836","nameIdentifierScheme":"WEKO"}],"names":[{"name":"白井, 友恵"}]}]},"item_6_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟大学"}]},"item_6_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"ETD"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Shirai, Tomoe"}],"nameIdentifiers":[{"nameIdentifier":"50835","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":"2019-08-05"}],"displaytype":"detail","filename":"h27ndk343.pdf","filesize":[{"value":"671.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文","url":"https://niigata-u.repo.nii.ac.jp/record/5752/files/h27ndk343.pdf"},"version_id":"b4db6c71-f73d-4b79-a1bc-0f6e8a7246cc"},{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-08-05"}],"displaytype":"detail","filename":"h27ndk343_a.pdf","filesize":[{"value":"158.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"要旨","url":"https://niigata-u.repo.nii.ac.jp/record/5752/files/h27ndk343_a.pdf"},"version_id":"4f26b69e-72c9-47ae-a116-27a1aff7427a"}]},"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":"thesis","resourceuri":"http://purl.org/coar/resource_type/c_46ec"}]},"item_title":"Caries-preventative effect of mouthguards containing a surface pre-reacted glass-ionomer filler．","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Caries-preventative effect of mouthguards containing a surface pre-reacted glass-ionomer filler．"},{"subitem_title":"Caries-preventative effect of mouthguards containing a surface pre-reacted glass-ionomer filler．","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["455","434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-06-16"},"publish_date":"2016-06-16","publish_status":"0","recid":"5752","relation_version_is_last":true,"title":["Caries-preventative effect of mouthguards containing a surface pre-reacted glass-ionomer filler．"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-15T03:38:57.933917+00:00"}
