The aim of study was to evaluate the intensity and spectral composition of the fluorescence emission of devitalized teeth before and after whitening. The object of research became 36 devitalized extracted human teeth which had been removed for medical reasons in patients of different age. Measuring of the spectra of fluorescent properties of the objects was carried out in the Institute of Physics, National Academy of Sciences. It was performed by a comparative evaluation of the fluorescence spectra of hard tissue of devitalized teeth in patients of different age groups before and after whitening.fluorescencedevitalized teethwhiteningфлуоресценциядепульпированный зуботбеливание[Александров М.Т.
