Relationship Between Oral Lichen Planus and Autoimmune Thyroid Diseases

Clinical Value of the Relationship Between Oral Lichen Planus and Autoimmune Thyroid Diseases

On the basis of previous studies, a validation cohort will be established to explore the relationship between oral lichen planus and autoimmune thyroid diseases, and a disease efficacy prediction strategy can be formed.

For oral lichen planus patients, the prevalence of Hashimoto's thyroiditis will be investigated and the relationship between levels of anti-TG, anti-TPO antibodies and severity of oral lichen planus will be determined.
