Dysaesthesia
Pronunciation: dis-es-THEE-zhah
An unpleasant, abnormal sensation in the oral tissues, including burning, tingling, or numbness, that may occur spontaneously or in response to a stimulus.
Full Definition
Oral dysaesthesia is a broad term covering aberrant sensory experiences such as burning, prickling, numbness, or a foreign-body sensation in the oral cavity, often in the absence of identifiable organic pathology. It overlaps clinically with burning mouth syndrome but extends to other abnormal oral sensations not covered by that diagnosis. Dysaesthesia can be a manifestation of neuropathic pain, medication side effects, or psychological factors. Editors should note the British English spelling 'dysaesthesia' versus the American English 'dysesthesia', and should ensure consistency with journal house style. The term should not be used interchangeably with 'paraesthesia', which specifically denotes tingling or numbness.
Usage
Usage note: British English: dysaesthesia; American English: dysesthesia. Do not use as a direct synonym for paraesthesia (tingling/numbness) or burning mouth syndrome (a discrete diagnostic entity).
