Burning mouth syndrome and saliva: detection of salivary trace elements and cytokines

Burning mouth syndrome (BMS) is considered a syndrome with an unknown cause. Roles of various trace elements and cytokines in saliva have been implicated in the development of BMS. The aim of the present study was to compare the levels of salivary trace elements [magnesium (Mg), zinc (Zn), copper (Cu)] and interleukin (IL)-2 and IL-6, and to search for a correlation between depression/anxiety and salivary trace elements and cytokines in BMS patients and controls.
