Familial dysautonomia is an inherited autosomal recessive disease found almost exclusively in Ashkenazi Jews. It is characterized by selective damage to the sensory, motor, and autonomic peripheral nervous system. The main clinical features include decreased pain sensation, impaired temperature and blood pressure regulation, lack of tearing, absent tendon reflexes, and fungiform papillae on the tongue. The purpose of this study was to explore in depth and to verify the oral and dental status in familial dysautonomia. Twenty-two patients and 44 match-paired healthy persons of Ashkenazi descent were examined. Patients and parents had only little concern for their oral conition. Caries prevalence was lower than normal and plaque accumulation was increased in all patients. Dental trauma was found in 59% of the patients, and 32% showed orodental self-mutilation. Dental age was within normal range, and dental arch measurements implied proportionally small jaws and little crowding. The low caries rate may be related to the known "hypersalivation" in familial dysautonomia and/or a possible change in the salivary composition and content, caused by chronic autonomic denervation.
