As sample subjects, 14,692 in total children (3,647 children aged 4 to 5 years in nursery schools or kindergartens and 11,045 children aged 6 to 11 years in elementary schools) were selected in Niigata city in 1995. The data on the numbers of teeth present, dental caries and pit and fissure sealants were obtained from their dental records. The mean DMFT for elementary schoolchildren rapidly increased from 0.25 in the first grade to 1.58 in the forth grade. After the forth grade, however, this increasing tendency went down from 1.58 to 1.97 in the sixth grade. The changing trends in the number of questionable caries for observation (CO teeth) and pit and fissure sealants were similar to that of the mean DMFT. Furthermore, the percentage of teeth with pit and fissure sealants for each intact tooth was 19.3% in all grades. The mean DMFT in the groups with and without pit and fissure sealants was 0.75 and 1.33 in all grades, respectively. The difference in the mean DMFT between the two groups was statistically significant (t-test, p<0.01). The results of the study demonstrated that a caries prevention program should be conducted especially for the first molars because of their high caries susceptibility, and also strongly suggested that pit and fissure sealant was effective in caries prevention. For making a more effective caries prevention program, a new system to apply pit and fissure sealant to CO teeth at dental clinics, on the basis of the data from regular dental check-ups, should be established.","subitem_description_type":"Abstract"},{"subitem_description":"今回、年中児から小学6年生の第一大臼歯を対象に調査を行い、今後のう蝕予防対策の充実を図る上での基礎資料を得た｡本報では、第一大臼歯のう蝕有病状況、およびフィシャーシーラントの処置状況について報告する｡調査対象は、新潟県新潟市の1995年度の年中、年長児3,647人、小学生11,045人の第一大臼歯である。調査は、1995年度定期歯科健診に併せて実施された。第一大臼歯の萌出状況、 う蝕有病状況、フィッシャーシーラソトの処置状況について、各学年ごとに分析を行った。さらに、小学学童をシーラント処置歯の有無により分類し、それぞれの平均DMF歯数を学年別に比較した｡その結果、平均DMF歯数は、萌出歯数の増加に伴い、小学1年生で0.25本、小学3年生で0.96本と上昇していった。しかし、小学4年生以降、平均DMF歯数の上昇が鈍り、小学6年生では1.97本であった。要観察歯(CO歯)数、シ-テント処置歯数についても同様の傾向が認められた。健全歯全体に占めるシーラント処置歯の割合は、小学生全体では19.3％であった。フィッシャーシ-ラント所有者別平均DMF歯数については、全学年の平均では、シーラント歯所有学童の平均DMF歯数が0.75本なのに対し、非所有学童の平均DMF歯数は1.33本であり、差は統計学的に有意であった(t検定、p<0.01） 学童のう蝕予防を検討する際には、第一大臼歯に重点を置く必要があると考えられる。また、フイッシャ-シーラントのう蝕予防効果は今回の調査からも強く示唆された。今後、保育園や学校などの施設と歯科医院とが連携を取り、平均DMF歯数が低年齢で急上昇するというう蝕の特性をとらえながら、小窩裂溝部COに対するフィッシャーシーラント処置をシステム化することで、より有効なう蝕予防対策に結びつくものと考える｡","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"152759","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yoshihara, Akihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"152760","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sasaki, Takeshi"}]},{"nameIdentifiers":[{"nameIdentifier":"152761","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Ota, Keiko"}]},{"nameIdentifiers":[{"nameIdentifier":"152762","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hagiwara, Wataru"}]},{"nameIdentifiers":[{"nameIdentifier":"152763","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kishi, Hiroshi"}]}]},"item_7_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟歯学会"}]},"item_7_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_7_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0018300X","subitem_source_identifier_type":"NCID"}]},"item_7_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03850153","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"葭原, 明弘"}],"nameIdentifiers":[{"nameIdentifier":"152754","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐々木, 健"}],"nameIdentifiers":[{"nameIdentifier":"152755","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"太田, 啓子"}],"nameIdentifiers":[{"nameIdentifier":"152756","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"萩原, 弥"}],"nameIdentifiers":[{"nameIdentifier":"152757","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岸, 洋志"}],"nameIdentifiers":[{"nameIdentifier":"152758","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":"2019-08-19"}],"displaytype":"detail","filename":"NS_27(2)_13-16.pdf","filesize":[{"value":"519.6 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NS_27(2)_13-16.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/25887/files/NS_27(2)_13-16.pdf"},"version_id":"f40983a1-bc51-4551-88b5-0674a039dfa9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"questionable caries for observation","subitem_subject_scheme":"Other"},{"subitem_subject":"要観察歯","subitem_subject_scheme":"Other"},{"subitem_subject":"pit and fissure sealant","subitem_subject_scheme":"Other"},{"subitem_subject":"フィッシャーシーラント","subitem_subject_scheme":"Other"},{"subitem_subject":"the first molar","subitem_subject_scheme":"Other"},{"subitem_subject":"第一大臼歯","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":"第一大臼歯のう蝕有病およびフィッシャーシーラントの処置状況","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"第一大臼歯のう蝕有病およびフィッシャーシーラントの処置状況"},{"subitem_title":"第一大臼歯のう蝕有病およびフィッシャーシーラントの処置状況","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["456","1323"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-08-22"},"publish_date":"2013-08-22","publish_status":"0","recid":"25887","relation_version_is_last":true,"title":["第一大臼歯のう蝕有病およびフィッシャーシーラントの処置状況"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:55:53.928709+00:00"}
