Paper Abstract

In this paper we report the results of measurement of the penetration of the radiation from different visible light emitting diodes (LEDs) inside dental tissue. The experiments are made using several different LEDs with wavelengths between 450 nm and 800 nm and power densities between 50 and 250 mW/cm2, which are the most frequently used in the clinical practice with proved clinical effect. The experimental results show that the penetration depends on the wavelength and the type of tissue. The results can be employed in the clinical practice for determining radiation dosage in the treatment of periodontal diseases.
