Burning mouth and saliva.
Stomatodynia is the complaint of burning, tickling or itching of the oral cavity, and can be associated with other oral and non-oral signs and symptoms. However, the oral mucosa often appears normal, with no apparent underlying organic cause to account for the symptomatology. The etiology is unknown, though evidence points to the participation of numerous local, systemic and psychological factors. Among the local factors, saliva may play an important role in the symptoms of burning mouth. Saliva possesses specific rheological properties as a result of its chemical, physical and biological characteristics - these properties being essential for maintaining balanced conditions within the oral cavity. Patients with burning mouth present evidence of changes in salivary composition and flow, as well as a probable alteration in the oral mucosal sensory perception related particularly to dry mouth and taste alterations. On the other hand, alterations in salivary composition appear to reflect on its viscosity and symptomatology of burning mouth. Saliva is a field open to much research related to burning mouth, and knowledge of its properties (e.g., viscosity) merits special attention in view of its apparent relationship to the symptoms of burning mouth. The present study describes our clinical experience with burning mouth, and discusses some of the aspects pointing to salivary alterations as one of the most important factors underlying stomatodynia.
