The purpose of this study is to get images (pictures) of oral lesions, which occur inside the mouth, before the patient's surgery using a special camera. These pictures will be used in our research to evaluate a new technology that uses a laser and takes pictures of the microscopic structure of tissue. The technology is called "reflectance confocal microscopy." We would like to compare what the camera sees to biopsies (pathology) of the same area. We will evaluate the pictures obtained from the patient to determine whether this technology may be useful in the future. We hope this technology can be used as a tool for early diagnosis of oral cancers and for guiding surgery.
