C. Data collection. Archived dental records from female patients treated during the past three years at the University of Mississippi School of Dentistry and the Dental/Dental Emergent Care Clinic (Jackson Medical Mall) will be examined. Each patient record will be assigned a study number, and data will be entered on an Excel spreadsheet using that study number. Since the pregnancy outcome is part of the UMC Hospital record, the principal investigator will link the dental and hospital records using the patient name. However, the data collected will use a research number. Following the procedure for linking the patient records, the patient name will be discarded. Thus, it will not be possible to link an individual patient to the study data.
