In Vitro Study of Light Radiation Penetration Through Dentin, According to the Wavelength

Based on their biological, analgesic and antibacterial effect, lasers are becoming more widely used in clinical practice in the recent years. In order to obtain a therapeutic effect and to prevent dental pulp alteration in the treatment of hard tooth tissue, the parameters of laser radiation should...
