A Study of Tooth Erosion in People With Esophagogastric Cancer

This is a 15-item questionnaire. The questionnaire asks subjects to quantify, during a specified duration of time, the number of times they have consumed or completed a task (ex. alcohol intake, cigarette use, and teeth brushing frequency). Additionally, the questionnaire further asks subjects to quantify their GERD symptoms and risk factors prior to diagnosis. All study procedures will be completed in one visit as part of a standard-of-care clinic visit.
