[Burning mouth].

Abstract

BACKGROUND: The complaint of burning mouth is fairly common. Epidemiological studies suggest a prevalence of around 15% in postmenopausal women and between 0,7 and 7,9% for the general population. PURPOSE: The purpose of this article is to present a review of the literature on epidemiology, clinical symptoms, etiology, diagnosis, treatment and prognosis of burning mouth and burning mouth syndrome. RESULTS AND CONCLUSIONS: Potential causal factors have been extensively studied and reviewed, suggesting a multifactorial aetiology, that apparently includes local, systemic and psychogenic factors. However, reports of their relative importance are conflicting. Consequently this lack of evidence is reflected in inconsistent guidelines for diagnosis and treatment. Most of the authors emphasize the importance of history taking and clinical intraoral examination for diagnosis. The symptom of burning mouth associated with clinical mucosal abnormality has to be differentiated from burning mouth syndrome (BMS), a condition in which no mucosal abnormality is evident on examination. Whereas the symptom of burning mouth associated with clinical mucosal signs is described to be often manageable by eliminating possible causal factors, the background of most of the proposed treatments for BMS is empiric or even purely anecdotal. Only a few randomised controlled studies have been performed on treatment outcome. Their differing results are presented in a short overview.
