The purpose of this study was to examine the healing process of the tongue wounds caused by the Nd: YAG contact laser.
SEM was used, focusing mainly on the dermal papillae, and the results were compared with the healing process of the wound by a dental bar.
In the case of the laser group, on the 4th day, the wound was filled with connective tissue. On the 7th day, regenerating dermal papillae were observed at the edge of the wound. On the 28th day, the wound healed, but the dermal papillae looked like mountains.
In the case of the control group, on the 7th day, regenerating dermal papillae were observed over the entire surface of the wound. Their papillae in the center of the wound were morphologically different from the original ones.
