The purpose of this study is to analyze the optical properties of human dentin and the relationship between the color spectrum and metal elements in the dentin. 120 specimens of human dentin sample with a thickness of 0.5 mm (±0.05 mm) were made. Reflectance values were measured by a spectrophotometer CAS-ID 1 with a white backing and a black backing. Scattering coefficients, absorption coefficients, R-infinity, CIELAB color coordinates L^*, a^*, b^* and Color depth SQ were calculated based on each reflectance value. Metal elements in dentin were analyzed by electron probe X-ray microanalyzer (EPMA) and Fe, Zn, Mg, Cu and Ni in 10 areas of each dentin specimen were quantified and averaged. Mean L^* value of dentin was 11.6±4.7, 29.6±27.3 for SQ, 70.1±11.3 for a^*, 11.6±4.3 for C^* and -0.1±2.1 for b^*. Ni indicated a positive correlation with a^* and b^* value, Zn showed a positive correlation with L^* value. On the other hand, Mg indicated a negative correlation with a^* value. It was concluded that those three metal elements could create the dentin color defined in this study.", "subitem_description_type": "Other"}]}, "item_2_source_id_13": {"attribute_name": "雑誌書誌ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00017474", "subitem_source_identifier_type": "NCID"}]}, "item_2_text_10": {"attribute_name": "著者所属(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Department of Fixed Prosthodontics, School of Dentistry, Iwate Medical University"}]}, "item_2_text_2": {"attribute_name": "記事種別(日)", "attribute_value_mlt": [{"subitem_text_value": "研究"}]}, "item_2_text_3": {"attribute_name": "記事種別(英)", "attribute_value_mlt": [{"subitem_text_language": "en", "subitem_text_value": "Original"}]}, "item_2_text_9": {"attribute_name": "著者所属(日)", "attribute_value_mlt": [{"subitem_text_value": "岩手医科大学歯学部歯科補綴学第二講座"}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2002-12-24"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "KJ00002373620.pdf", "filesize": [{"value": "578.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensefree": "Creative Commons : 表示 - 非営利 - 改変禁止", "licensetype": "license_free", "mimetype": "application/pdf", "size": 578800.0, "url": {"label": "KJ00002373620", "url": "https://iwatemed.repo.nii.ac.jp/record/1657/files/KJ00002373620.pdf"}, "version_id": "fc5e732d-e177-4744-870e-aa7b443107a8"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Human dentin", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Color", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Metal element", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "象牙質に関する色彩学的研究 : 含有金属元素による影響について", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "象牙質に関する色彩学的研究 : 含有金属元素による影響について"}, {"subitem_title": "Colorimetric Study of Human Dentin : Relationship between Color Coordinates and Metal Elements in the Dentin", "subitem_title_language": "en"}]}, "item_type_id": "2", "owner": "5", "path": ["120", "397"], "permalink_uri": "https://iwatemed.repo.nii.ac.jp/records/1657", "pubdate": {"attribute_name": "公開日", "attribute_value": "2002-12-24"}, "publish_date": "2002-12-24", "publish_status": "0", "recid": "1657", "relation": {}, "relation_version_is_last": true, "title": ["象牙質に関する色彩学的研究 : 含有金属元素による影響について"], "weko_shared_id": 5}
