Serum Concentration of Vitamin D in Patients with Oral Lichen Planus.

Objectives: The vitamin D receptor is involved in immunologically mediated diseases such as oral lichen planus. Some studies suggest an association between lower vitamin D concentrations and a higher risk of inflammatory conditions such as oral lichen planus. The aim of this study was t investigate 1) whether there is a difference in serum vitamin D concentration in patients with oral lichen planus compared to patients in the control group, 2) whether there is a difference in serum vitamin D concentration in patients with erosive compared to non-erosive forms of oral lichen planus, 3) whether there is a difference in serum vitamin D concentration in patients with developed oral cancer and those without cancer.

Inflammatory Markers and Incidence of other Autoimmune Diseases in Patients with Oral Lichen Planus.

Introduction: Oral lichen planus (OLP) is a chronic immune, inflammatory disease of the oral cavity of a still unknown etiology.

Materials And Methods: The study involved 63 subjects diagnosed with oral lichen planus and 63 subjects without pathologic changes in the oral mucosa who were classified as controls. All subjects were given a detailed medical history at first screening.
