Summary

The goal of this interventional research is to determine the impact of vitamin D intake on substances in saliva, pain, tooth movement, and the density of the bone around teeth in patients during orthodontic treatment. It will compare the effects of vitamin D supplementation with a placebo to clarify its role in the aforementioned aspects of orthodontic care. The main questions it aims to answer are: How does vitamin D supplementation affect salivary opiorphin levels in patients undergoing fixed orthodontic mechanotherapy at Specialist Hospital Universiti Sains Malaysia? What is the impact of vitamin D supplementation on pain perception during fixed orthodontic mechanotherapy? How does vitamin D supplementation influence the rate and quality of tooth movement in patients undergoing fixed orthodontic mechanotherapy? What is the relationship between salivary opiorphin levels and pain perception in patients supplemented with vitamin D during fixed orthodontic mechanotherapy? How does vitamin D supplementation affect changes in alveolar bone density during fixed orthodontic mechanotherapy? Researchers will provide vitamin D to the experimental group while the control group receives a placebo to see if vitamin D intake has an impact on substances in saliva, pain, tooth movement, and the density of the bone around teeth during orthodontic treatment. Participants will: Take vitamin D or a placebo every day for 4 months Visit the clinic once every 4 weeks for checkups and tests Participate in the study for a duration of up to 4 months

Interventions

Type	Name	Description
DIETARY_SUPPLEMENT	Vitamin D (Calcitriol)	Participants receive a 1000 IU vitamin D tablet daily for 4 months during orthodontic treatment. The supplement is provided in tablet form to participants in the experimental group.
OTHER	Placebo	Oral administration of a placebo (look-alike substance without active vitamin D ingredient), taken daily for 4 months during fixed orthodontic mechanotherapy. The placebo is formulated to match the appearance (e.g., shape, color) and dosage form of the vitamin D supplement provided to the experimental group.
