No. of bitstreams: 0 Previous issue date: 2022-01-01 Background: The repair of bone defects has been the subject of many studies that have shown inconclusive results as to what is the best bone substitute. Material and Methods: Bone defects (0 2 mm) were induced on the tibia of seventy-two rats, which were distributed into the following four groups/treatments (n=18 each): Control: no treatment; EMD: enamel matrix derived protein; PBM: photobiomodulation therapy (660 nm, 0,035 W, 60 s); EMD + PBM: EMD and immediate treatment with PBM (660 nm, 0,035 W, 60 s). Six animals from each group were euthanized after 10, 30 and 60 days. Histologi…
