This paper is the last one in the series of publications on the investigation of the capability of Optical Coherence Tomography (OCT) in diagnostic of state of oral cavity mucosa. Part II demonstrates the diversity of optical images, different forms specific to leukoplakia, lichen planus and squamous cell carcinoma on the basis of the investigation of 56 pathologic lesions of 43 patients with precancer and cancer of oral cavity. The OCT sensitivity in malignancy detection in oral cavity is high - 83%, specificity is 98%, and accuracy is 81%. The kappa coefficient of interobserver agreement is 0.76.

[Optic coherent tomography in evaluation of the buccal mucosa status. Communication 1. Normal mucosa]. / Opticheskaia kogerentnaia tomografiia v otsenke sostoianiia slizistoi obolochki polosti rta. Soobshchenie 1. Normal'naia slizistaia obolochka.

The potentialities of optic coherent tomography (OCT) in the diagnosis of the buccal mucosa status were studied and the results are presented in two communications. Communication 1 demonstrates the tomograms of various parts of normal buccal mucosa and methods of their identification as exemplified by analysis of 1180 in vivo and 43 ex vivo OCT images. Using parallel histo-tomographic comparison, the authors distinguished the main signs of optic images, depending on the type of epithelium and characteristic features of the connective tissue stroma in various parts of the buccal mucosa. These signs are essential for understanding the optic images of the mucosa in disease, which will be shown in communication 2.
