We have developed a prototype optical coherence tomography (OCT) system for the imaging of hard and soft tissue in the oral cavity. High-resolution images of <i>in vitro</i> porcine periodontal tissues have been obtained with this system. The images clearly show the enamel–cementum and the gingiva–tooth interfaces, indicating OCT is a potentially useful technique for diagnosis of periodontal diseases. To our knowledge, this is the first application of OCT for imaging biologic hard tissue.
