A Survey Based Pilot Study on Three Dimensional Images and Animated Videos in Oral Histopathology
Background: Oral Histopathology is the study of diseased tissues in a life-like manner. Unfortunately biopsy tissue gives two dimensional and static images. Additionally the descriptions of such images are in three dimensional terms such as cords, arcading, organoid etc., which most of the time is confusing to the students and readers. Therefore it becomes very difficult to correlate the descriptions mentioned in the textbooks with the images viewed under microscope. Researchers have been trying to develop various softwares to convert two dimensional images into three dimensional but again such images would still be static. Therefore three dimensional animation videos which would depict the etiopathogenesis in life like manner, should be available at each university to promote e-learning especially for oral histopathology speciality, popularity of which has been vanishing day by day. Such videos are already available for other speciality of dentistry. With this concept, a preliminary effort was been taken to design such animations for histopathological aspect of ameloblastoma and shown to students. Methods: A survey was conducted amongst bachelor of dental surgery students, interns and master of dental surgery students using questionnaire, to know the understanding level of oral histopathology through traditional teaching methods. Additionally few images and videos have been created using various softwares and feedback was evaluated. Results: Three dimensional videos were perceived as effective and efficient as E-learning tools for oral histopathology education. Conclusion: User feedback on the educational content was helpful. A website exclusively for this work was suggested and planned for E-learning.
