Effect of 650 nm low-power laser on bone morphogenetic protein in bone defects induced in rat femors.

Purpose: To investigate the influence of 650 nm GaAlAs laser on the action of bone morphogenetic protein (BMP) in bone defects produced in rat femurs.

Methods: The sample consisted of 12 male albino Wistar rats (Rattus norvegicus). The animals were randomly divided into four experimental groups.
