Quantitative measurement of tongue movement with ultrasound had also been reported these years. Therefore, ultrasonography has become a valuable tool for study tongue morphology as well as tongue functions. In the present development of broadband networking today, it is technological advances an aspects of our lives. There are many applications of word wide web in medical field have been reported, such as, on-lined outpatient service system, distance consultation, and multimedia teaching system. It was the purpose of this study, to set up an oral ultrasound teaching system on World Wide Web, and to provide a better learning for our students. Sixty-one volunteers were chosen from dental students at Taipei Medical University. All images used in this study were taken from these students. This teaching system provides on-line simulation of ultrasound machine. Students can learn any time and anywhere through Internet. With the use of multimedia technology, sound based dynamic ultrasound images can display through Internet so as to enhance the learning efficiency on tongue movements during swallowing and phonation. Furthermore, we applied flash technique to provide students a movie styled introduction of the teaching program. In addition, a questionnaire was designed to evaluate the learning effect of this system. The result demonstrated that over 90% of the students held positive to this teaching system and agree with that it helps enhancing their learning on oral ultrasonography. In the future, we hope to enrich the content and apply more advanced multi-media technologies to improve our teaching system. Widely application of such web-based teaching system on Internet in other fields of dental education and research are strongly suggested.
