Paper Abstract

Our investigations have been devoted to OCT capabilities in imaging normal and diseased tooth structures and different types of oral mucosa. OCT tomograms distinctly exhibit the structural elements of oral mucosa. Depending on localization and keratinization, different types of mucosa are also seen in OCT images. OCT images of those parts where epithelium evidences high keratinization substantially differ from images of those parts where epithelium evidences low or no keratinization in its normal state. OCT imaging allows one to clearly differentiate between caries and noncaries lesions, which is very important in practical dentistry. OCT has made it possible to quite accurately diagnose a fissure caries in the early stage that has been unreliable with an X- ray examination. The OCT technique is capable of dynamic monitoring the restorative process. It also allows in vivo examination of fillings as well as the state of surrounding tissues. It is possible to detect filling defects caused by an incorrect filling procedure either during the process of restoration of some time later. The results of our investigations suggest that OCT is a potentially useful modality for clinical and research dentistry.
