学校ベースの歯垢除去プログラムの効果を示す。5年生から8年生の児童を対象に、学校での毎日の歯間ブラシとフロスによる歯垢除去が、口腔衛生、歯肉の炎症、う蝕に及ぼす影響を検討した。フッ化物を含まない歯磨剤を使用した。対照群には歯垢除去法の指導は行わず、学校での歯垢除去活動も行わなかった。治療群の生徒は3学年の間、訓練された職員の監督下で毎日歯垢除去を実践した。すべての参加者は、最初に歯垢(PHP)、歯肉の炎症(DHC)、う蝕(DMFS)の検査を受けた。治療群の女児では、歯垢スコアの平均が有意に減少し(28%)、女児と男児では歯肉炎スコアの平均変化が有意に減少した(それぞれ40%と17%)。DMF表面スコアの調整平均値は、治療群では対照群より13%低かった。この群間差は統計学的に有意ではなく、すべて中間面と遠位面の所見(26%)によって説明された。この差は統計学的有意差に近づいた(P=0.07)。
The benefits of a school-based plaque removal program are presented. Children in grades 5-8 were inclined in a study which was designed to determine the effect on oral hygiene, gingival inflammation and dental caries of removing dental plaque through supervised daily flossing and toothbrushing in school. A fluoride-free dentifrice was used. Controls did not receive instruction in plaque removal procedures nor did they engage in plaque removal activities at school. For three school years the students in the treatment group practiced daily plaque removal, supervised by trained personnel. All participants were examined initially for plaque (PHP), gingival inflammation (DHC) and dental caries (DMFS). Girls in the treatment group showed a significant reduction (28%) in mean plaque scores and, for girls and boys, the mean changes in gingivitis scores were significantly reduced (40% and 17%, respectively). Adjusted mean incremental DMF surface scores were 13% lower in the treatment group than in the control group. The difference between groups was not statistically significant and was accounted for entirely by the findings in mesial and distal surfaces (26%). This difference approached statistical significance (P=0.07).
