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\u00b0C, 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 \u03bcm 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":"\u5185\u5bb9\u8a18\u8ff0","attribute_value_mlt":[{"subitem_description":"\u5b66\u4f4d\u306e\u7a2e\u985e: \u535a\u58eb\uff08\u6b6f\u5b66\uff09. \u5831\u544a\u756a\u53f7: \u7532\u7b2c4145\u53f7. \u5b66\u4f4d\u8a18\u756a\u53f7: \u65b0\u5927\u9662\u535a\uff08\u6b6f\uff09\u7532\u7b2c343\u53f7. \u5b66\u4f4d\u6388\u4e0e\u5e74\u6708\u65e5: \u5e73\u621028\u5e743\u670823\u65e5","subitem_description_type":"Other"}]},"item_6_description_53":{"attribute_name":"\u5b66\u4f4d\u8a18\u756a\u53f7","attribute_value_mlt":[{"subitem_description":"\u65b0\u5927\u9662\u535a\uff08\u6b6f\uff09\u7532\u7b2c343\u53f7","subitem_description_type":"Other"}]},"item_6_dissertation_number_52":{"attribute_name":"\u5b66\u4f4d\u6388\u4e0e\u756a\u53f7","attribute_value_mlt":[{"subitem_dissertationnumber":"13101\u7532\u7b2c4145\u53f7"}]},"item_6_full_name_3":{"attribute_name":"\u8457\u8005\u5225\u540d","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"50836","nameIdentifierScheme":"WEKO"}],"names":[{"name":"\u767d\u4e95, \u53cb\u6075"}]}]},"item_6_publisher_7":{"attribute_name":"\u51fa\u7248\u8005","attribute_value_mlt":[{"subitem_publisher":"\u65b0\u6f5f\u5927\u5b66"}]},"item_6_select_19":{"attribute_name":"\u8457\u8005\u7248\u30d5\u30e9\u30b0","attribute_value_mlt":[{"subitem_select_item":"ETD"}]},"item_creator":{"attribute_name":"\u8457\u8005","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Shirai, Tomoe"}],"nameIdentifiers":[{"nameIdentifier":"50835","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"\u30d5\u30a1\u30a4\u30eb\u60c5\u5831","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":"\u672c\u6587","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":"\u8981\u65e8","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":"\u8a00\u8a9e","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"\u8cc7\u6e90\u30bf\u30a4\u30d7","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\uff0e","item_titles":{"attribute_name":"\u30bf\u30a4\u30c8\u30eb","attribute_value_mlt":[{"subitem_title":"Caries-preventative effect of mouthguards containing a surface pre-reacted glass-ionomer filler\uff0e"},{"subitem_title":"Caries-preventative effect of mouthguards containing a surface pre-reacted glass-ionomer filler\uff0e","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["453/455","432/433/434"],"pubdate":{"attribute_name":"\u516c\u958b\u65e5","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\uff0e"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2021-03-01T08:28:34.411049+00:00"}
