Patients with temporomandibular disorders (TMDs) showed higher parathyroid hormone levels, indicating a more pronounced response to vitamin D deficiency. Assessment and correction of vitamin D deficiency are recommended for individuals with TMDs.
Area of Science:
- Biochemistry
- Endocrinology
- Oral and Maxillofacial Medicine
Background:
- Temporomandibular disorders (TMDs) are complex conditions affecting the jaw joint and surrounding muscles.
- The relationship between mineral and hormonal imbalances, particularly vitamin D, and TMDs requires further investigation.
Purpose of the Study:
- To compare serum levels of vitamin D, parathyroid hormone, calcitonin, calcium, phosphorus, and magnesium in patients with and without TMDs.
- To investigate the potential role of these biochemical markers in the pathophysiology of TMDs.
Main Methods:
- A prospective observational study involving 50 patients with TMDs and 50 age-, sex-, and date-matched healthy controls.
- Diagnosis of TMDs was confirmed through physical and radiological examinations.
- Serum levels of 25(OH) vitamin D, parathyroid hormone, calcitonin, calcium, magnesium, and phosphorus were quantified.
Main Results:
- No significant differences were observed in age or sex between the TMD and control groups.
- Serum levels of 25(OH) vitamin D, calcitonin, calcium, magnesium, and phosphorus did not differ significantly between the groups.
- Parathyroid hormone levels were significantly higher in patients diagnosed with TMDs compared to healthy controls.
Conclusions:
- Patients with TMDs exhibit a more pronounced increase in parathyroid hormone in response to vitamin D deficiency.
- These findings suggest a potential link between vitamin D deficiency and TMDs, highlighting the importance of screening and supplementation.
- Further research is warranted to elucidate the causal relationship and therapeutic implications.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...
Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
