MICAP is a new notation in which the teeth are indicated by letters (I-incisor, C-canine, P-premolar, M-molar) and numbers [1,2,3] which are written superscript and subscript on the relevant letters. FDI tooth notation is a two digit system where one digit shows quadrant and the second one shows the tooth of the quadrant. This study aimed to compare the short term retention of knowledge of two notation systems (FDI two digit system and MICAP notation) by lecture method.
Undergraduate students [N=80] of three schools participated in a cross-over study. Two theory-driven classroom based lectures on MICAP notation and FDI notation were delivered separately. Data were collected using eight randomly selected permanent teeth to be written in MICAP format and FDI format at pretest (before the lecture), post-test I (immediately after lecture) and post-test II (one week after the lecture). Analysis was done by SPSS version 20.0 using repeated measures ANCOVA and independent t-test.
The results of pre-test and post-test I were similar for FDI education. Similar results were found between post-test I and post-test II for MICAP and FDI notations.
The study findings indicated that the two notations (FDI and MICAP) were equally mind cognitive. However, the sample size used in this study may not reflect the global scenario. Therefore, we suggest more studies to be performed for prospective adaptation of MICAP in dental curriculum.
MICAP是一种新的牙位表示法，其中牙齿用字母（I-切牙，C-尖牙，P-前磨牙，M-磨牙）和数字[1,2,3]表示，数字写在相关字母的上标和下标位置。FDI牙位表示法是一种两位数系统，其中一位数字表示象限，另一位数字表示该象限内的牙齿。本研究旨在通过讲授法比较两种牙位表示系统（FDI两位数系统和MICAP表示法）知识的短期保持情况。
三所学校的本科生[N = 80]参与了一项交叉研究。分别进行了两场基于理论的关于MICAP表示法和FDI表示法的课堂讲座。在预测试（讲座前）、后测试I（讲座后立即进行）和后测试II（讲座后一周）时，使用八颗随机选择的恒牙，要求学生用MICAP格式和FDI格式写出牙位，收集数据。使用SPSS 20.0版本进行重复测量协方差分析和独立样本t检验。
FDI教学中预测试和后测试I的结果相似。MICAP和FDI表示法在后测试I和后测试II之间也发现了相似的结果。
研究结果表明，这两种表示法（FDI和MICAP）在认知方面是等效的。然而，本研究中使用的样本量可能无法反映全球的情况。因此，我们建议进行更多研究，以便在牙科课程中前瞻性地应用MICAP。
