Background Burning mouth syndrome ( BMS ) is a disorder characterized by chronic mouth pain in the absence of objective clinical abnormalities. Vitamin or mineral deficiencies may have a role in BMS , but data regarding the prevalence and relevance of hematinic deficiencies are conflicting. We aimed to determine the frequency of specific laboratory abnormalities in patients with BMS . Methods We retrospectively reviewed the results of screening blood tests in patients with BMS at our institution between January 2003 and December 2013. Results Among 659 patients with BMS , the most common decreased values or deficiencies were vitamin D 3 (15%), vitamin B 2 (15%), vitamin B 6 (5.7%), zinc (5.7%), vitamin B 1 (5.3%), thyrotropin ( TSH ) (3.2%), vitamin B 12 (0.8%), and folic acid (0.7%). Laboratory values for fasting blood glucose and TSH were increased in 23.7% and 5.2%, respectively. Conclusions In patients with symptoms of BMS , our results suggest it is reasonable to screen for fasting blood glucose, vitamin D (D 2 and D 3 ), vitamin B 6 , zinc, vitamin B 1 , and TSH . Deficiencies of vitamin B 12 and folic acid were rare (<1% abnormal).
