Established in 1992, this multidisciplinary center provides patient care (diagnoses and management strategies) as well as clinical research protocols for oral manifestations of autoimmune diseases such as Sjögren's syndrome (SS), Systemic Lupus Erythematosus (SLE), Systemic Sclerosis (scleroderma), and Rheumatoid Arthritis (RA).

In addition to clinical care, the Center provides professional and patient educational seminars within the state of Florida, nationally, and internationally.

Clinical, translational, and basic science research is ongoing; the goal is to develop improved diagnostic tools and therapies by understanding disease etiopathogenesis.

To schedule an appointment for diagnosis and management of oral concerns such as "dry mouth" and autoimmune related problems of the head and neck, please telephone the Oral Medicine Clinic at 352-273-6739.
