Abstract :Hereditary sensory and autonomic neuropathies (HSAN) are rare genetic syndromes of unknown etiology. They are seen in early childhood and categorized in six different types by their symptoms. HSAN type 4 has an autosomal recessive transmission, with such major characteristics as loss of sense of pain, self-mutilation, anhydrosis and mental retardation. Sympathetic innervations are deficient despite the existence of sweat glands. Sufferers are hypotonic without any tendon reflexes, and neuro-motor development is retarded. In some cases tactile sensation and vibration may be intact. Biting injuries due to lack of pain sensation cause laceration, ulceration and scarring of the tongue, lips and other parts of oral mucosa. Tooth luxation and severe dental attrition have been observed. This case report presents oral and dental findings, surgical treatments and prosthetic rehabilitation of an 11- year-old boy with HSAN type 4.Keywords : Hereditary sensory and autonomic neuropathy, type IV, Dental needs, Removable partial prosthesis
