The Potential Effect of the Local Administration of Vitamins C and E on Orthodontic Treatment: a Randomized Clinical Trial

• Vitamin C (Ascorbic Acid): This intervention involves the administration of vitamin C, which is known for its antioxidant properties. The concentration will be 120 mg in 1.2 ml, and the produced volume will be divided by six lower anterior teeth; each tooth will receive 0.2 ml (20 mg) of the vitamin C. It is hypothesized to accelerate orthodontic tooth movement by reducing oxidative stress and promoting collagen synthesis.

• Vitamin E (Tocopherol Acetate): This intervention uses vitamin E, another antioxidant, thought to reduce inflammation and support tissue repair, potentially improving the effectiveness of orthodontic treatment by enhancing tissue recovery and reducing side effects. The concentration will be 60 mg in 0.4 ml, and the produced volume will be divided by six lower anterior teeth; each tooth will receive 0.07 ml (10 mg) of the vitamin E.

Saline Solution (Control): The control group will receive a saline solution, which is a placebo, allowing for the comparison of the effects of vitamin C and vitamin E on orthodontic tooth movement without the influence of additional nutrients.
