To test whether dental students' accuracy of treatment decision making for dentine caries using radiographs improved after using a decision aid (DA).
Dental students (n = 227) assessed the need for treatment for proximal surfaces of a test set of radiographs for a scenario patient. These 20 simulated bitewings contained 56 proximal test surfaces of which 14 were sound, 19 had enamel lesions and 23 had dentine lesions according to the histological "Gold standard". The students next used a DA, followed by re-evaluation using the same test radiographs. In this test-retest design, paired two-sided T tests were used to test for improvement in sensitivity (Se), specificity (Sp) and log diagnostic odds ratio (DOR) of treatment decisions for dentine caries.
The students' initial mean Se, Sp and DOR were 0.66, 0.82, and 12.9 (SD 0.11, 0.10 and 8.2). After using the decision aid, mean values improved (0.67, 0.83 and 14.1) (P = 0.83, 0.07 and 0.04).
Using the stand alone DA led to a slight improvement in student performance.
测试牙科学学生在使用决策辅助工具（DA）后，对 X 光片上牙本质龋治疗决策的准确性是否有所提高。
牙科学学生（n = 227）评估了一名模拟患者的一组 X 光片近中面治疗需求。这 20 张模拟咬合翼片包含 56 个近中测试面，根据组织学“金标准”，其中 14 个是完好的，19 个有釉质病变，23 个有牙本质病变。学生们接下来使用了 DA，然后使用相同的测试 X 光片重新评估。在这个测试-再测试设计中，使用双侧配对 T 检验来检验治疗牙本质龋的决策的敏感性（Se）、特异性（Sp）和对数诊断优势比（DOR）的改善情况。
学生们最初的平均 Se、Sp 和 DOR 分别为 0.66、0.82 和 12.9（SD 0.11、0.10 和 8.2）。使用决策辅助工具后，平均值有所提高（0.67、0.83 和 14.1）（P = 0.83、0.07 和 0.04）。
使用独立的 DA 导致学生表现略有提高。
