This is a prospective study with the aims: (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.
Participants will attend 2 study visits. Visit 1 of the study will consist of screening during the baseline visit. It will include administration of questionnaires, informed consent, collection of salivary samples, helping to download the app and/or helping to set up the smartphone to receive text notifications, and assisting with the demonstration of taking surveys on smartphones.
Track Your Happiness app, a smartphone and/or text-based notification system to take surveys, will collect data on people's experiences across a random sample of the moments of their lives. Participants will receives notifications 3 times per day at random times, and will be prompted to answer questions related to the burning mouth, to exercise, and a random selection of non-clinical Track Your Happiness questions, e.g., "Are you interacting with anyone right now?" "How do you feel right now?" Participants will receive these notifications for 12 weeks.
The final study visit (visit 2) will take place 12 weeks after Visit 1. Visit 2 will consist of questionnaires and collection of salivary samples.
