In this paper we demonstrate real-time in vivo and in vitro OCT images of human dental tissue obtained in a clinical setting. For the first time we have used a compact, commercial prototype OCT system with a surgical microscope as a beam delivery system for investigations of dental tissue. We have imaged demineralised tissue, caries lesions and restored teeth and demonstrate the detection of changes in tissue microstructure. We discuss the details of this system and its potential and limitations with respect to dental applications.
Laser safety training at present is based primarily on conventional lectures. We present a multimedia concept which allows for adjusting of the training to laser users' specific applications and needs. Applying a blend of written and spoken text, drawings, photographs, animations and videos, computer based multimedia training is capable of conveying information very efficiently. Preferences regarding medical fields and modes of presentations are taken into account. This concept meets the recommendations of international standards and guidelines concerning contents and is capable of presenting information in variable quantity, depth and speed thus increasing the training efficiency for the individual.
