Objective: To evaluate the radioprotective effect of a homeopathic solution in salivary function and in parotid glands morphology of irradiated rats. Materials and Methods: The sample consisted of 150 rats randomly divided in 6 groups. The groups were named based on the substance administered: Control- saline solution; Irradiated Control- saline solution and 15 Gy of X radiation; Alcohol-hydroalcoholic solution dynamized at 15 CH; Irradiated Alcohol- hydroalcoholic solution dynamized at 15 CH and 15 Gy of X radiation; Homeopathy- 0.25 ml (1mL/kg) of the irradiated hydroalcoholic solution and dynamized at 15 CH; Irradiated homeopathy- homeopathic solution and 15 Gy of X radiation. Each group was subdivided in 5 different subgroups, based on the time point of euthanasia: 12 hours, 3, 10, 17, and 24 days. The medication was administered for 7 days before and 7 days after the radiation treatment. On the day of euthanasia, salivation was induced with pilocarpine and collected. The animals were then sacrificed and the parotid glands were removed. Results: Salivary function analysis showed that only group irradiated homeopathy euthanized on day 17 had a statistical significant difference when compared to other irradiated groups, presenting a higher salivation flow rate. The only group that showed statistical significant difference in the number of acini over the time was the irradiated alcohol group, which presented a tendency of reduction. Conclusion: The homeopathic solution presented a late radioprotective effect based on salivary function and morphological analysis of the parotid gland.
