Figure 2 Treatment of an alveolar bony defects with an erbium-doped yttrium aluminum garnet laser and advanced platelet-rich fibrin+. A: Radiographic examination showed an apical lesion and bone loss (black arrow) of tooth 22; B: Infected lesions were treated with erbium-doped yttrium aluminum garnet laser with water spray; C and D: Intrabony defects were filled with allograft bone mixed with advanced platelet-rich fibrin+ (A-PRF+), and the periodontal wound was covered with double layers of A-PRF+ membranes, and then the wound was sutured.
