摘要
目的 分析乳牙菌斑液中无机阳离子含量与龋易感性的关系。方法 将 4 1名 3～ 5岁儿童 ,按龋齿情况将其分为 3组 :无龋组dft=0 ,CSI=0 ,n =2 0 ;龋低危组 0 <dft<5 ,0 <CSI≤ 10 ,n =11;龋高危组dft≥ 5 ,CSI >10 ,n =10。用离子色谱测定各受试者息止菌斑液中无机阳离子浓度。结果 无龋组与高危组、低危组与高危组钠离子、镁离子水平有显著性差异 (P <0 .0 5 ) ,镁离子与dft、CSI有正相关性 (r分别为 0 .5 6 ,0 .6 4 )。结论 提示乳牙息止菌斑液镁离子浓度与乳牙龋病。
Objective To analyse the contents of inorganic cations in plaque fluid in children aged 3～5 years,and to study their relationship with caries susceptibility.Methods According to their caries status,41 children aged 3～5 years were separated into three groups:caries free group,dft=0,CSI=0,n=20;low caries risk group,0<dft<5,0<CSI≤10,n=11;high caries risk group,dft≥5,CSI>,n=10.The Contents of inorganic cations in plaque fluid was determined by ion chromatography.Results The contents of sodium and magnesium were significantly higher in caries active group than in caries positive and caries free groups(P< 0.05).A positive correlation can be found between the contents of magnesium in plaque fluid with dft,CSI(r=0.56,0.64).Conclusion Contents of magnesium in plaque fluid in children aged 3～5 years may be used as a predictor of individual caries risk.
