Eligibility

All
Age
18 Years to 60 Years

Inclusion criteria

Inclusion criteria: 1. Patients aged 18-60 years required surgical removal of the mandibular third molar. 2. ASA (American Society of Anesthesiologists) I or II. 3. Willingness to participate and provide informed consent. 4. Surgery required an ostectomy and/or an odontectomy.

Exclusion criteria

Exclusion criteria: 1. Presented history of allergy to medications used in this study. 2. Pregnancy or breastfeeding. 3. Presented history of systemic disease or conditions contraindicated for magnesium as follows: 3.1. Patients with renal impairment (creatinine clearance of less than 30 mL/min). Since magnesium is cleared renally, patients with renal insufficiency may have an increased risk of heart block or hypermagnesemia. 3.2. Patients taking urinary excretion-reducing drugs, such as calcitonin, glucagon, and potassium-sparing diuretics, may increase serum magnesium levels. 3.3. Patients taking fluoroquinolones, aminoglycosides, bisphosphonates, calcium channel blockers, tetracyclines, and skeletal muscle relaxants. The absorption rate of these drugs may be influenced by the intake of magnesium. 3.4. Patients with a type of muscle weakness called myasthenia gravis. 4. Presented with ongoing orofacial pain on the day of surgery. 5. Presented history of medication or supplement intake that can affect the body's magnesium level. 6. Presented history of analgesic intake within 1 week prior to surgery. 7. Presented psychiatric disorders including depression, anxiety disorders, and psychotic disorders. 8. Presented signs and symptoms of third molar-associated local and/or systemic infection or pathology.
