The study subject will be asked to complete the standard adult medical and dental health history questionnaire provided by the UNC SOD and will be provided with the UNC Chapel Hill Notice of Privacy Practices and the Consent for Purposes of Treatment, payment and health care operation. Other than the screening consent, these are standard practices followed by UNC SOD for all patients. The study is mandated to adhere to theses protocols prior to treating a patient at the UNC SOD. An oral examination will be performed by the research dentist to evaluate if the patient meets inclusion criteria, after the subject has signed all documents. Upon consent to participate, appointments will be made for treatment at UNC SOD, as it would happen as part of their regular treatment.
