0(<10^4 CFU/mL)をLow SM,Class 1(10^4〜10^5 CFU/mL)以上をHigh SMと評価し,1年生時から6年生時までのSMレベルの変化パターンを解析し,永久歯齲蝕発生状況との関連について検討した.各学年におけるカリエスフリーからの永久歯齲蝕発生者率は,いずれの学年時も1割前後であり,学年間の有意差は認められなかった.6年間における永久歯カリエスフリーからの齲蝕発生者の1年前のSMレベルを検索した結果,High SMが82.9%であった.また,1年生時のSMレベル別に検索した結果では,1年生時にHigh SMであった場合,齲蝕発生者の94.6%は直前のSMレベルがHigh SMであったのに対し,Low SM群の場合,直前のSMレベルがHigh SMである確率は22.2%であり,Low SMである確率の方が高かった.以上の結果より,1年生時にLow SMと評価された者については,その後のSMレベルの変動はほとんど齲蝕発生に影響しないが,1年生時にHigh SMと評価された者は,学童期を通じてHigh SMを示した翌年に永久歯齲蝕を発生する確率がきわめて高いことがわかった.","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"乙第1584号"}]},"item_10006_publisher_5":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"大阪歯科学会"}]},"item_10006_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open
