Abstract

Introduction. Life induced fluorescence (LIFE) diagnostics can be used as an imaging system of precancerous and neoplastic lesions of the oral mucosa. Neoplastic lesions are visible in pseudo colours, healthy tissue in green colour and abnormal tissue in red colour. All the observed colours present different intensity. Colour intensity is relevant to the grade of dysplasia, carcinoma progress and is called Numerological Value of Color Index (NCV). The aim of our study was to find correlation between autofluorescence diagnostics combined with NCV assessment and histopathological findings of taken specimen biopsies. Patients and methods. 10 patients participated in our study. Lesions affected a variety of intraoral sites. The most common location was: buccal, gingival and mandibular mucosa. Patients were examined using Life Induced Fluorescence diagnosis (400 - 750 nm wavelength) with Numerological Value of Color index (NCV) using Onco LIFE system. Afterwards the specimen biopsies from the lesions were taken and histopathological examination was performed. Results. Different NCV and dependence of NCV on the histopathological findings were observed. Conclusion. Diagnostic procedures with the application of white-light imaging with LIFE imaging is not only a significantly faster method and a better diagnostic tool of preneoplastic and neoplastic lesions, but there exist also correlations between measured NCV and histopathological diagnosis. The farther investigations are necessary in order to prove these preliminary findings.
