Abstract

カリオスタットと齲蝕の関係について数多くの報告があるが,歯周疾患との関係については少ない。学童期における歯肉炎の多くは,不潔性歯肉炎であり,齲蝕と同様プラークが原因である。そこで中学生437名を対象に,齲蝕活動性試験カリオスタット^[○!R]および唾液潜血テストサリバスター潜血用^[○!R]を行い,齲蝕歯数(D歯数)・歯肉炎との関係について調査した。1)カリオスタット24時間判定結果(24H)においては,D歯数・歯肉炎と高度の相関関係が認められた(p<0.001)。また,歯肉炎の程度より3つに群分けし,カリオスタット(24H)との関係をみたところ,有意な分布の差が認められた(χ^2検定p<0.001)。2)カリオスタット48時間判定結果(48H)においては,D歯数・歯肉炎との間に相関関係が認められた(p<0.05p<0.001)。しかし歯肉炎の群分けにおいては,カリオスタット(48H)に有意な分布の差が認められなかった。3)サリバスターはD歯数と有意な関係は認めなかった。しかし歯肉炎とは相関関係が認められた(p<0.05)。歯肉炎の群分けにおいては,サリバスターには,有意な分布の差が認められなかった。4)カリオスタット(24H)とサリバスターの間には,有意な関係が認められなかった。5)カリオスタット(24H)を用い, 1.0以上を基準として歯肉炎をスクリーニングし敏感度・特異度を算出すると,それぞれ0.34,0.83となった。サリバスターで+以上をスクリーニング基準とすると0.55,0.55であった。歯垢を試料とするカリオスタットは,口腔衛生状態を反映し,齲蝕だけでなく,歯肉炎とも関係が深いことが考えられた。

In many cases, periodontal disease among the school age children is caused by bad oral hygiene and the main factor is also dental plaque as well as dental caries. Many studies have been done on the relationship between Cariostat and dental caries. However few studies have been performed on the relationship between Cariostat and periodontal disease. The purpose of this study was to estimate the relationship between Cariostat and gingivitis. We examined the relationship among caries activity test (CARIOSTAT^[○!R]), salivary occult blood test (SALIVASTER^[○!R]), gingivitis, and dental caries in 437 junior high school children. 1. The Cariostat score after 24 h incubation was correlated significantly (p<0.001) with both dental caries (D-T) and gingivitis. When the gingivitis index was divided into three groups (severe and moderate/slight/normal), the distribution of Cariostat score among the three groups showed significant difference (chi-square test plt;0.001). 2. The Cariostat score after 48 h incubation was also correlated significantly with both dental caries (D-T) and gingivitis (plt;0.05 and plt;0.001 respectively). However, the distribution of Cariostat score among the three groups did not show any difference. 3. The Salivaster test score was correlated with gingivitis (plt;0.05), but not with dental caries. The distribution of Salivaster score among the three groups did not show any significant difference. 4. The Cariostat score after 24 h incubation was not correlated with the Salivaster test score. 5. The specificity and sensitivity for gingivitis were 0.34 and 0.83, respectively, when the Cariostat score of 1.0 after 24 h incubation was used as the screening point. On the other hand, both the specificity and sensitivity were 0.55 when the Salivaster test score of (+) was used as the screening point. The Cariostat score after 24 h incubation was correlated with both gingivitis and dental caries. These results suggest that the Cariostat score could reflect the oral hygiene status and be correlated with gingivitis as well as with dental caries.
