面尚未成洞龋早期诊断方法的进展

Pragression of early diagnostic method of early caries on the occlusal surface

近 2 0年来 ,由于预防工作的广泛展开 ,特别是氟化物的广泛应用 ,龋病的发病率明显下降。但牙合面龋所占比例却有所增加 ,常表现为在表面正常的牙釉质下向深层发展。因此 ,如何对尚未成洞龋作出早期正确诊断已成为口腔医生日益关注的问题 ,传统的视诊、探诊法已远远不能满足要求 ,迫切需要开发新型、有效的龋病诊断技术。

Caries incidence had declined in the last twenty years.The cause for this declination may be multiple, but predominantly it may be the increased use of fluoride.The incidence of occlusal caries in present day population has increased and caries lesion develop slowly underneath the enamel. The traditional diagnostic methods of caries,such as visual inspection, probing,are inadequate. More researches have been reported in purpose to design, improve and create new diagnostic methods.
