[Oral medicine 4. Clinical aspects and treatment of taste and smell disorders].

Taste and smell perception are closely related. Many chemosensory disorders which result in faulty taste are in fact smell disorders. Causes ofchemosensory disorders which call for attention are ageing, medication, natural proteins, burning mouth syndrome, nerve injuries, aerate disorders in the neighbourhood of the sense ofsmell, damage to the smell epithelium, and oncologic diseases or their treatment. A chemosensory disorder has implications for food delight and psychological well-being, may lead to weight loss or increase and to deficient intake of vitamins and minerals. A chemosensory disorder can be treated by medication, surgical intervention, improvement of oral health, smell rehabilitation, and dietary advice.
