Safety Irradiation Parameters of Nd:YAP Laser Beam for Endodontic Treatments: An In Vitro Study

Table 1

Different irradiation conditions are shown in function of predetermined setting of the apparatus. The average of output powers and the average of energy densities are calculated for the fiber diameter of 200 µm of the Nd:YAP laser.
