The objective of this research was to determine if a computerized simulated dental exercise predicts students' subsequent performance in preclinical technique courses. Twenty-nine first-year dental students voluntarily participated in the investigation prior to their first experience with a dental handpiece. These students prepared an ideal Class I amalgam on an ivorine mandibular first molar tooth after viewing ten-minute videotaped instructions. Students completed the Class I amalgam on a computerized dental treatment simulator (SIM). All participants' SIM scores were correlated with sub-test scores of the Dental Admission Test (DAT), predental overall grade point average (GPA), predental Biology/Chemistry/Physics grade point average (BCP), and grades from the first two preclinical laboratory technique courses (Lab 1 and Lab 2). The results showed a significant correlation between the simulator scores and DAT sub-test scores of Academic Average and Total Science, as well as Lab 1 scores. Based on these results, the simulator appears to be a good measure of general cognitive ability, including cognitive ability required to complete uncomplicated preclinical exercises.
本研究的目的是确定计算机模拟牙科练习是否能预测学生在临床前技术课程中的后续表现。29名一年级牙科学生在首次接触牙科手机之前自愿参与了这项调查。这些学生在观看了10分钟的录像指导后，在一颗象牙质下颌第一磨牙上制备了理想的I类银汞合金。学生们在计算机化牙科治疗模拟器（SIM）上完成了I类银汞合金的制备。所有参与者的SIM分数与牙科入学考试（DAT）的子测试分数、牙科预科总体平均绩点（GPA）、牙科预科生物/化学/物理平均绩点（BCP）以及前两门临床前实验室技术课程（实验1和实验2）的成绩相关。结果显示，模拟器分数与DAT学术平均分和总科学子测试分数以及实验1分数之间存在显著相关性。基于这些结果，模拟器似乎是衡量一般认知能力的良好指标，包括完成简单临床前练习所需的认知能力。
