lndex:GI, Gingival Crevicular Fluid:GCF量, Probing Depth:PD)を行った｡また,実験終了時に, 2種類の電動歯ブラシの使用感に関するアンケート調査を行い,それぞれの特徴を分析した｡プラーク除去率については,改良型電動歯ブラシ使用群が旧型電動歯ブラシ使用群に比べ,舌側において,有意に除去率が高かった(平均:84.73% vs72.74%)。歯肉炎については,GI,GCF,PDのいずれにおいても,プラーク除去率の高かった部位と一致して有意に改善した(GI:平均0.2vs0.6,GCF量:平均0.19μl vs 0.35μl, PD:平均2.1mm vs 2.4mm)。本研究より,改良型電動歯ブラシは旧型電動歯ブラシに比べ,より良好なプラーク除去効果が得られ,特に舌側で優れており,プラーク除去効果と並行して歯肉炎も改善された。またアンケート調査より, 2種類の電動歯ブラシは統計学的に2群に判別され(η^2=0.93),判別に寄与する要因は大きい順に,本体部の振動,振動音,口腔内での毛先のあて方が理解しやすいか否かという結果となり,改良型電動歯ブラシは旧型電動歯ブラシに比べて,主に本体部の振動が弱く,振動音が小さく,口腔内での毛先のあて方が容易であることから使いやすいという結論を得た｡","subitem_description_type":"Abstract"}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"153395","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Sugimoto,
