Определение безопасного повышения температуры внутри пульпарной камеры зуба при проведении фотодинамической терапии in vitro

Abstract

The objective of the study is to determine the mode of laser radiation and ultraviolet light-emitting diode which are used to activate the photosensitiser «Photolon» during photodynamic therapy in vitro. The objects of the study were 20 newly extracted posterior teeth. A new photosensitiser for the photodynamic therapy «Fotolon» (Belmedpreparaty) has been used in this study. Activation of the photosensitiser «Fotolon» was performed using a laser diode with a maximum output power of 250 mW and a wavelength of 660 nm and UV LED lamp LEDEX WL-070 with a wavelength of 460 nm and a power of 1000 mW. As a result, it was determined the optimal mode of the laser and ultraviolet LED light for activation of the photosensitiser «Fotolon» with no heating in the pulp chamber above the threshold 40°C
