Eligibility

Inclusion Criteria:

• patients attending the Clinic for Graduate Periodontics at The University of Texas health Science Center at Houston School of Dentistry who are in need of a Free Gingival Graft procedure to augment keratinized gingiva, augment ridge, or cover recession defects.
• systemically healthy or with controlled common systemic conditions, such as hypertension, that will not affect wound healing.
