The sample comprised 1571 orthodontic patients (585 males and 986 females) without any systemic disorders such as dentofacial deformity and/or CLP. The present study used clinical records, panoramic radiographs, and study models. Results showed that, 195 patients (12.5%) had missing teeth excluding third molars. As for the number of missing teeth, one tooth was 90 patients (46.1%), two teeth were 63 patients (32.3%) and over three teeth were 42 patients (21.6%). The lower second premolars were the most frequent missing teeth (25.8%), followed by the lower lateral incisors (15.9%), the upper lateral incisors (11.4%), the upper second premolars (11.2%) and the upper first premolars (6.9%). The ratio of male to female was 1:1.1. 54 patients (3.4%) had supernumerary teeth. Regarding the number of supernumerary teeth, one tooth was 54 patients (85.2%) and two teeth were 8 patients (14.8%). The most common location was maxillary anterior region (88.7%), followed by the maxillary molar and mandibular anterior regions. The ratio of male to female was 2.5:1. The results were almost the same as those in the previous reports. An increase in patients with over six teeth congenital absence may be related to indication of public health insurance in 2012.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟歯学会", "subitem_publisher_language": "ja"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00182415", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0385-0153", "subitem_source_identifier_type": "PISSN"}]}, "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": "坂上, 馨", "creatorNameLang": "ja"}, {"creatorName": "Sakaue, Kei", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "高橋, 功次朗", "creatorNameLang": "ja"}, {"creatorName": "Takahashi, Kojiro", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "丹原, 惇", "creatorNameLang": "ja"}, {"creatorName": "Nihara, Jun", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "森田, 修一", "creatorNameLang": "ja"}, {"creatorName": "Morita, Shuichi", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "齋藤, 功", "creatorNameLang": "ja"}, {"creatorName": "Saito, Isao", "creatorNameLang": "en"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2022-05-31"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "46(2)_83-88.pdf", "filesize": [{"value": "643KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": "643KB", "url": {"objectType": "fulltext", "url": "https://niigata-u.repo.nii.ac.jp/record/2000555/files/46(2)_83-88.pdf"}, "version_id": "3fc1b132-a15d-437d-9e39-e47f9a705939"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "矯正患者", "subitem_subject_language": "ja", "subitem_subject_scheme": "Other"}, {"subitem_subject": "歯数異常", "subitem_subject_language": "ja", "subitem_subject_scheme": "Other"}, {"subitem_subject": "過剰歯", "subitem_subject_language": "ja", "subitem_subject_scheme": "Other"}, {"subitem_subject": "先天性欠如歯", "subitem_subject_language": "ja", "subitem_subject_scheme": "Other"}, {"subitem_subject": "6歯以上の先天性部分(性)無歯症患者", "subitem_subject_language": "ja", "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": "最近10年間の新潟大学医歯学総合病院矯正歯科における歯数異常症例の臨床統計調査", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "最近10年間の新潟大学医歯学総合病院矯正歯科における歯数異常症例の臨床統計調査", "subitem_title_language": "ja"}, {"subitem_title": "Clinical survey of patients with abnormality of the number of teeth at Orthodontic Department, Niigata University Medical and Dental Hospital in recent 10 years", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1653965479978"], "permalink_uri": "http://hdl.handle.net/10191/0002000555", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-05-31"}, "publish_date": "2022-05-31", "publish_status": "0", "recid": "2000555", "relation": {}, "relation_version_is_last": true, "title": ["最近10年間の新潟大学医歯学総合病院矯正歯科における歯数異常症例の臨床統計調査"], "weko_shared_id": -1}
