3～5岁健康幼儿口腔挥发性硫化氢测量及影响因素分析

Levels of volatile hydrogen sulfide in oral cavity of 3-5 years old healthy children and influencing factors

目的通过检测3～5岁健康幼儿口腔挥发性硫化氢水平,评估幼儿口腔健康状况,分析幼儿口腔异味的重要影响因素。方法对340名3～5岁健康幼儿口腔挥发性硫化氢进行感官分析法评分及分析仪测量,记录多项口腔健康指数,分析感官分析法评分与仪器测量数值的关系,以及与口腔健康指数的多因素Logistic回归关系。结果 3～5岁健康幼儿口腔挥发性硫化氢水平均值为(46.72±23.27)×10-9。感官分析法评分和硫化氢分析仪读数之间相关系数r=0.807。舌苔指数、简化口腔卫生指数纳入以感官分析法评分为因变量的多因素Logistic回归方程。结论挥发性硫化氢分析仪可用于临床检测幼儿口腔异味。舌苔、软垢为幼儿口腔异味的重要影响因素。

Objective To examine the levels of volatile hydrogen sulfide（H_2S） in oral cavity of 3-5 years old healthy children and analyze the influencing factors. Methods The levels of volatile hydrogen sulfide in oral cavity were examined in a sample of 340 healthy children aged 3-5 years old.Oral malodor was measured with both organoleptic measurements and a portable volatile hydrogen sulfide monitor.Oral clinical status were assessed.Pearson′s correlation was used to determine the relationship between organoleptic scores（OS）,the levels of volatile H_2S and clinical parameters.Bivariate logistic regression analysis was performed to detect the degree of association between OS and clinical parameters. Results The mean level of volatile H_2S was 46.72±23.27.The correlation coefficient of OS and H_2S was 0.807.Tongue coating score and oral hygiene index were significantly associated with OS. Conclusion The portable hydrogen sulfide monitor could be used to diagnose oral malodor in children.Tongue coating and debris are the important factors that influence oral malodor in healthy children.
