Abstract
IntroductionIn many dental schools, traditionally, the undergraduate students undertake surgical procedures only after a brief course of didactic lectures and live clinical demonstrations. Though live demonstrations are preferred by the students, they regularly complain about an inadequate field of view due to limited visual access to the operating area. Hence, this method of demonstration has various limitations from the students’, instructors’, and the patients’ point of view. An effective clinical teaching modality could be achieved by using surgical cameras that can be fixed to the dental chair light unit for live demonstration and recording of the surgical procedures. However, commercially available surgical cameras are not cost-effective and hence not always affordable by teaching institutions. Methods and materialsThis paper describes a simple, cost-effective technique for real time visual demonstration of the surgical procedures using a high-resolution webcam which is fixed to the center of the dental chair light unit and is connected to a computer via USB and the webcam software is installed in the computer. ResultsThis arrangement can be used for live demonstration and also for video recordings. Currently, we have implemented the technique in demonstration of intraoral injection procedures and found it to be very successful. ConclusionThis simple and cost-effective method of real time visual demonstration of the surgical procedure creates a balance between the live demonstration and videotaped teaching with an added interactive component between the students and the instructor.
