Diagnosis and Evaluation of Patients in Need of Third Molar Removal or Suffering From Chronic Facial Pain

This protocol is designed to screen individuals with either third molars ("wisdom teeth") in need of removal, or with chronic orofacial pain as potential research subjects. Each individual will be thoroughly evaluated during the screening process, including past medical history and an appropriate physical examination. Other routine diagnostic procedures and tests may also be completed in order to help determine a subject's eligibility. These tests and procedures are of minimal risks and will be described in more detail in section III: "Study Procedures". Once the screening process is completed and eligibility determined, the subjects will be informed of their options to participate in one or more of the current NIDCR research studies. If no appropriate protocol is identified, recommendations for other treatment options may be given to the individual, their primary doctor, or referring physician/dentist.
