AIM
This study compared the impact of low-powered magnification on the detection of occlusal caries.
METHODS
The occlusal surfaces of 38 extracted teeth received caries ICDAS classification with and without magnification by two examiners. Histology was used as the gold standard.
RESULTS
No significant differences existed in terms of sensitivity, specificity, LR+, LR- and Az values for the two examiners and modalities. Interexaminer agreement was almost perfect for grades 0, 2, 3 irrespective of magnification. For grade 1, magnification resulted in lower agreement than unaided vision.
CONCLUSION
Magnification does not improve the detective performance of visual examination.
目的
本研究比较了低倍放大对窝沟龋检测的影响。
方法
对 38 颗离体牙的窝沟面进行了龋病 ICDAS 分类，两位检查者分别在放大和不放大的情况下进行了检查。以组织病理学为金标准。
结果
两位检查者和两种检查方式在敏感度、特异度、LR+、LR-和 Az 值方面均无显著差异。无论是否放大，对 0 、 2 、 3 级别的判断，两位检查者的一致性几乎为完美。而对于 1 级，放大检查的一致性低于非放大检查。
结论
放大并不能提高肉眼检查的检出性能。
