Abstract

某小学校の4 年,5 年,6 年生総数365 名中において,永久前歯の白斑の有無とカリオスタット<sup>Ⓡ</sup>試験,CAT 21 Buf<sup>Ⓡ</sup>試験,唾液流出量,口腔水分量,D 歯,DF 歯の有無の関係について調査を行った。1 .対象者365 名のうち55 名(15.1%)が永久前歯に白斑を認めた。2 .白斑の有無と各検査の値を比較し単変量解析を行ったところカリオスタット値の2.5 以上と2.0 以下(P=0.002),D 歯の有無(P=0.027)において有意な差を認めた。CAT 21 Buf<sup>Ⓡ</sup>試験,刺激唾液流出量,DF 歯において有意な差は認めなかった。3 .白斑を持つ53 名中でD 歯を有する群はカリオスタット値2.5 以上の割合が有意に多かった(P=0.031)。

Primary school children (aged 9~12 years old, N=365) were checked for initial caries (white spot) on their permanent anterior teeth. It was investigated whether there is a difference between the white spot and no white spot group with caries activity test (Cariostat<sup>®</sup>), buffer capacity test (CAT 21 Buf Test<sup>®</sup>), saliva flow rate, oral moisture, and existence of caries and filling.The findings are as follows :1.55 children (15.1%) had white spots on their permanent anterior teeth (white spot group) There was no significant difference among the 3 grade group (4, 5, 6 grade) in the prevalence of their permanent anterior white spot.2.There was the significant difference between the white spot students group and no white spot group in Cariostat score (more than 2.5/less than 2) and caries prevalence (no caries/caries) by variant analysis. The rate of saliva flow, oral moisture and the rate of buffer capacity test showed no significant difference in any cut off points.3.There was significant difference between decayed surfaces and Cariostat score in the white spot group. The prevalence of high caries risk children in the white spot group had higher caries prevalence than the low caries risk children in the white spot group.
