Burning Mouth Syndrome
Diagnosis of Burning Mouth Syndrome
Clinical evaluation Tests to exclude secondary causes Diagnosis of burning mouth syndrome requires oral symptoms as noted above and the absence of oral signs. Pain must occur on 50% of days, for>2 hours per day (some authors omit this potentially unreliable criterion), for>3 months. Burning mouth syndrome is a diagnosis of exclusion; therefore, testing for secondary causes should be thorough and may involve salivary flow measurement, blood tests to evaluate for systemic conditions, head and neck imaging studies, and biopsy.
