Participants: 6 Wislander rats, with a circular defect created in each parietal bone.
Intervention: The experimental group received infrared laser radiation on the left defect, while the control group was sham-irradiated.
Methods: After 28 days, bone metabolism was evaluated using Technetium-99m methylene diphosphonate scintigraphy.
Conclusion: The results showed no difference in bone metabolic activity between the laser-treated and control defects. This pilot study indicates that the infrared laser has no significant effect on bone metabolism in rats.
