title: Evaluation of salivary function in patients with burning mouth syndrome.
abstract: OBJECTIVE
  To investigate salivary function in patients with primary burning mouth syndrome (BMS) compared with control and to evaluate salivary hypofunction using salivary gland scintigraphy (SGS).
  
  
  METHODS
  A total of 33 patients with primary BMS and 30 control subjects were enrolled in our study. The severity of the pain and the burning sensation on a 10-cm visual analog scale (VAS) and the Oral Health Impact Profile-14 (OHIP-14) were assessed. Unstimulated and stimulated salivary flow rates (SFRs) were measured. (99m) Tc pertechnetate SGS was used to evaluate salivary gland function.
  
  
  RESULTS
  Unstimulated SFR in patients with BMS was significantly lower than that in the control group (0.11 ± 0.15 vs 0.21 ± 0.16 ml min(-1) , P = 0.014). There was no significant difference in stimulated SFR between the two groups. The VAS scores for oral pain and burning sensation, the total OHIP-14 score, and salivary gland function by salivary scintigraphy were not significantly different between BMS patients with normal flow rate and hyposalivation.
  
  
  CONCLUSIONS
  Patients with primary BMS exhibited a significant decrease in unstimulated SFR compared with control group. In addition, we could not find any difference in salivary gland function between BMS patients with or without hyposalivation.
