Details and patient eligibility

About

This entire protocol involves procedures that are standard care and will randomize subjects to of one two routine care procedures. Patients needing root coverage for gingival recession will be enrolled.

Full description

Each subject will be randomized to one of the treatments for the first side and the contralateral side will receive the other treatment. No risk or benefit is expected from being assigned to either group as both procedures are both standard care. In both groups, a commercially available allograft (ADM-D or ADM-S) will be used.

Allocation of subjects into test group or control group will be based on numbers drawn from a stack of sealed envelopes.

Grafting teeth with gingival recession is often done to improve esthetics and tooth sensitivity as well as prevent recession from progressing. When recession coverage procedures are done, a soft tissue graft material is inserted between the gums and the tooth to help decrease the amount of root exposure. This material is obtained from a donor and may originate from a deeper or shallower layer of the donor skin. The study team seek to determine if the origin of the graft material (deep or shallow) influences the amount of root coverage achieved.

---

6 participants in 2 patient groups, including a placebo group

Control Group: Acellular Dermal Matrix - Superficial cut (ADM-S)

Placebo Comparator group

Description:

A commonly used allograft material is the Acellular Dermal Matrix (ADM) which is harvested from human donor dermal tissues. Most commercially available ADM products are superficial cuts.

Treatment:

Other: Allograft Material ADM-S

Test Group:Acellular Dermal Matrix - Deep cut (ADM-D)

Active Comparator group

Description:

The use of a deep cut ADM for root coverage gingival plastic procedures.
