The objective was to evaluate the effect of photobiomodulation (PBM) using 980 nm diode laser therapy (0.60 W, 0.77 W cm −2 , 36 J, 46 J cm −2 , 60 s) irradiated in continuous wave mode by flat‐top hand‐piece on socket healing in the maxilla and mandible. A split‐mouth experimental design was performed on 6 dogs. The 3 rd premolar tooth was extracted from the maxilla and mandibles for both sides. The right‐sided sockets were irradiated (PBM group), and the left‐sided sockets were kept as control. Irradiation was done after extraction and at 48‐h interval for 14 days. Both the buccal and lingual sides were irradiated to reach a total irradiation time of 120 s. Bone density was evaluated at 3, 4 and 5 weeks using cone beam computed tomography. We showed that maxillary sockets in the PBM group had higher bone density compared to control one at 3, 4, 5 weeks ( P = 0.029, <0.001, <0.001), respectively. Mandibular sockets revealed no significant difference between PBM and control at 3 weeks ( P = 0.347), while at 4 and 5 weeks PBM group showed higher bone density ( P = 0.004, <0.001). In both groups, there was a significant increase ( P < 0.001) in bone density by time which was higher in the PBM group. We concluded that PBM using a flat‐top hand‐piece of 980‐nm improved the bone density of extraction sockets.
