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 \u003c 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", "download_preview_message": "", "file_order": 0, "filename": "h27ndk343.pdf", "filesize": [{"value": "671.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 671800.0, "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", "download_preview_message": "", "file_order": 1, "filename": "h27ndk343_a.pdf", "filesize": [{"value": "158.1 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 158100.0, "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"], "permalink_uri": "http://hdl.handle.net/10191/42131", "pubdate": {"attribute_name": "公開日", "attribute_value": "2016-06-16"}, "publish_date": "2016-06-16", "publish_status": "0", "recid": "5752", "relation": {}, "relation_version_is_last": true, "title": ["Caries-preventative effect of mouthguards containing a surface pre-reacted glass-ionomer filler．"], "weko_shared_id": 2}
