Background: The aim of this study was to investigate the experience of the combination of remote learning and virtual microscopy in oral histopathology teaching, a unique experience in China in response to the Covid-19 pandemic.Methods: 192 third-year dental students were recruited to participate in the course independently on the E-learning platform and Virtual Simulation Experiment Teaching Center of Stomatology of Nanjing Medical University. A questionnaire survey explored students' satisfaction with the education. Differences of assessment results among different groups were compared using Mann-Whitney U and independent-sample T tests.Results:The mean Theory test scores of the Online group (80.93±12.15) were significantly higher than those of the Traditional group (73.65±8.46) (P < 0.01). The mean total scores of the Online group (82.94±10.76) were significantly higher than those of the Traditional group (77.25±7.55) (P < 0.01). The percentage of high total test score (test score > 85) of the Online group (54%) was also significantly higher than that of the Traditional group (15%) (P< 0.01). Furthermore, both remote learning and virtual microscopy courses were well accepted by students according to the questionnaire. Conclusions: The application of remote learning and virtual microscopy have enhanced oral histopathology teaching in China in response to the Covid-19 pandemic.

Figure 1. ORCSolver is able to adapt a layout between different sizes and orientations at near-interactive rates, based on a single layout specification. The layout is adjusted to fit the aspect ratio, and the optional "CHI2019" logo and buttons 1, 2, 3 are automatically removed as space gets scarce.
