Virtual Reality (VR) applications in medicine had significant improvements. 3D visualization of various anatomical parts using advanced medical scanner images, anatomy education, surgery operation simulation, virtual simulator for laparoscopic skills, virtual endoscopy, psychotherapy and rehabilitation techniques are some of the VR applications in medicine. Integration of the haptic devices into VR applications increased quality of the systems. By using haptic devices, the user can not only feed information to the computer but can receive information from the computer in the form of a felt sensation on some part of the body. In this thesis a dental education simulator is developed by using a computer, a monitor, a haptic device and stereoscopic devices. The entire jaw model, all teeth and decay is modeled in the virtual environment. It is possible to diagnose the decay and remove the decay region by using different dental instruments developed in the system. Different graphical rendering methods like Marching Cubes, Ray-casting on GPU are implemented and compared. The system is used by dentists from METU Health Center and Ankara University and performance tests are applied to the system. By this system it is expected to develop a more realistic and effective preclinical education. Several advantages offered by the simulator include: an effective learning environment without undue fear of mistakes, facilitation of repetition, provision of opportunities to quantitatively assess student skills, rapid training environment without an instructor and lower the cost of dentist training.
