| 摘 要： | 目的研究激光龋齿探测仪(DIAGNOdent,DD)诊断乳、恒牙窝沟龋的界值范围。方法收集离体磨牙、乳磨牙,清洁,用DD探测面可疑点荧光值,沿该点切开,在体视显微镜下阅片,以镜下所得龋损分级结果作为参照,分析DD对应龋损各阶段的荧光值(d值)范围,即DD界值,并评价按这一标准对龋病的诊断与临床磨开后诊断的一致率。结果DD探测磨牙窝沟龋,d值为0时显示无龋损,1～33之间显示龋损局限在釉质1/2或者正常,大于45显示龋损已超过釉质1/2;DD探测乳磨牙窝沟龋:d值为0时同样显示无龋损,大于25显示龋损已超过釉质1/2。且按实验所得乳磨牙龋病的DD界值标准诊断与临床磨开后的诊断一致率较好。结论DD探测龋病时,一个适当的界值标准可以很好地辅助临床诊断龋病。

| Abstract: | Objective To study the cut-off points of DIAGNOdent(DD)for detecting caries in occlusal surface of primary and permanent teeth.Methods Extracted molars and deciduous molars were collected.Their occlusal fissures were detected by DD after cleaning.Then the teeth were cut following the detecting point,and examined with stereoscope.We analyzed the accordance between DD's diagnosis in the standard of the cut-off points and the diagnosis in clinic.Results When DD detected molar fissures,it showed no caries if th... |
