Histopathological studies of rat submandibular salivary glands following low‐energy laser irradiation using gallium‐arsenide semi‐conductor laser were conducted. The mitoses of duct epithelial cells without atypia increased between 1 and 24 h after irradiation, reaching a maximum of greater than 5 times control values by 24 h. Mitoses of duct epithelial cells had a tendency to be more frequent in granular ducts, less in striated ducts, and still less in intercalated ducts. Qualitative differences in the effect of low‐energy lasers on salivary gland epithelia were also noted. This is the first experimental study of the effect of low‐energy laser on salivary glands.
