RecruitingClinical trialReducing Patient Memory Recall in the Burning Mouth Patient PopulationThe goal of this study is to learn about burning mouth syndrome symptoms in real time in patients with burning mouth syndrome. The main questions it aims to answer are: (1) To test the ability of a smartphone app to collect repeated observations of individual data to assess fluctuations in BMS symptoms (pain) at multiple points in the day as they happen; (2) To evaluate a panel of salivary biomarkers in patients with burning mouth syndrome (BMS) and to study their relationship with clinical variables. With a collaboration between Penn Dental Medicine and Wharton School of Business, our proposal aims to vastly improve the characterization of burning mouth syndrome through the use of a smartphone app and/or text-based notification. Participants will attend 2 study visits where they will complete questionnaires and provide saliva samples and will respond to notifications/text message prompts on their smart phone 3 times a day for 12 weeks.
