Multiple efforts for study control will be implemented. To control for the impact that watching a video twice a day may have Group 2 will watch a control video. Group 1 will watch a dental hygiene video. Clinical evaluators will also be blinded to prevent bias when evaluating the two groups clinically. One examiner will conduct initial exams. A second examiner will conduct all subsequent exams with no knowledge of what group each patient is assigned. Evaluators will be calibrated pre-study evaluating hygiene patients at the dental clinic.
