Abstract

幼稚園児(5,6歳)94人を対象として,齲蝕活動性試験Cariostat® (三金工業)・Dentocult-SM® Strip mutans (Orion Diagnostica)・Dentocult-LB® (Orion Diasnostica)と口腔内状態の関連性について調査した。1 : Cariostatは,全員から採取可能であった。しかしDentocult-SM Strip mutans・Dentocult-LBは,85名(90.4%)しか採取できなかった。2 : 幼稚園児の齲蝕有病者率75.3%1人平均d歯数4.04歯,平均df歯数6.55歯,CSI 13.9であった。3 : Carinstat®とDentocult-LB®は,d歯数,df歯数,CSIの各齲蝕指数との関係において高度の相関が認められた(p<0.001)。4 : Dentocult-SM® Strip mutansは,d歯数,df歯数と高度の相関性が認められた(p<0.01)。5 : すべての試験方法において,健全群と未処置群,処置終了群と未処置群の間に有意差が認められた(p<0.05)。6 : Cariostat®はスクリーニング基準を1.5/2.0間にしたとき,敏感度0.703,特異度0.857となった。Dentocult-SM® Strip mutansでは2/3間で敏感度0.359,特異度0.900であったDentocult-LB®では10<sup>3</sup>/10<sup>4</sup>間で,敏感度0.625,特異度0.85となった。Cariostat®とDentocult-LB®は齲蝕指数と同程度の相関が認められたが,Dentocult-SM® Strip mutansの相関はやや低かった。

The purpose of this study was to investigate the relationship between Caries' status and three caries activity tests ; Cariostat® (Sankin Kougyo), Dentocult-SM® Strip mutans (Orion Diagnostica), Dentocult-LB® (Orion Diagnostica), in 94 preschool children aged 5-6 years old.1) Cariostat® samples were obtained from all children. Both Dentocult SM® Strip mutans and Dentocult LB® were obtained from 85 (90.4%) of the children.2) The caries prevalence, mean dt, mean dft and mean CSI of the preschool children were 75.3%, 4.04, 6.55 and 13.91, respectively.3) The Cariostat® score and Dentocult-LB® score were correlated significantly (p<0.001) with the caries index (dt, dft and CSI).4) The Dentocult-SM® Strip mutans score was correlated significantly (p<0.01) with the caries index (dt and dft).5) When the children were divided in to three groups (caries free/treated/untreated.), the distribution of all caries activity test scores showed significant differences between the three groups (Chi-square test p<0.05).6) Setting the Cariostat ® score 1.5 as the screening level, the sensitivity and specificity for caries were 0.703 and 0.857, respectively. On the other hand, the Dentocult-SM® Strip mutans score, when we used the score 2 as the screening level, had sensitivity and specificity of 0.359 and 0.900, respectively. In addition, the Dentocult-LB® score, when we used the score 10<sup>3</sup> as the screening level, had sensitivity and specificity of 0.625 and 0.850, respectively. The Cariostat® and Dentocult-LB® scores showed almost the same level of correlation to the caries index. However, the Dentocult-SM® Strip mutans showed a slightly lower correlation than Cariostat® and Dentocult-LB® .
