comparison of the learning of two notations: a pilot study

introduction: 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. methods: 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. results: 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. conclusion: 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.
