Coverage of exposed root surfaces is not indicated or intended. Patients needing root coverage surgical procedures re not eligible for enrollment (similar to our past studies, see references 11,12) * Female patients who have undergone a hysterectomy, tubal ligation, or menopause, and non-pregnant women of child-bearing potential as eligible. * Patients who are nonsmokers or former smokers are eligible.
