Abstract:

Orthodontic tooth movement occurs as a result of prolonged application of controlled mechanical forces. Recent studies have focused on the effects of systemic or local applications of medications and the intake of dietary supplements as well as the mechanical forces. Factors affecting the orthodontic tooth movement are parathyroid hormone, thyroid hormones, estrogen, vitamin D3, eicosanoids, nonsteroidal anti-inflammatory drugs (NSAIDs), paracetamol, corticosteroids, bisphosphonates, cholesterol drugs, anticonvulsants, oral contraceptives, alcohol and nicotine use, nitric oxide, and fluoride. These medications have an important effect on the rate of tooth movement and treatment time. NSAIDs decrease tooth movement, but paracetamol has no effect. Parathyroid and thyroxin hormones increase tooth movement. Bisphosphonates have a strong inhibitory effect. Vitamin D3 stimulates tooth movement and dietary calcium seems to reduce it. It is important to discuss with patients about the consumption of these substances during orthodontic treatment.
