Brief Summary: The objective of this study is to evaluate clinical and patients-centered parameters of 3-month outcome of the enamel-derived matrix (EMD) application on wound healing process of the donor palatal area after free gingival graft (FGG) removal.
Detailed Description: This is a randomized, parallel, double-blind clinical trial. The population that will be evaluated in this is study will be select at Science and Technology Institute - ICT-Sao Jose dos Campos, College of Dentistry.

Patients will be assigned to one of the treatments groups:

* Control Group - Free Gingival Graft (n = 22): Atraumatic extraction surgery and free gingival graft for sealing the entrance of the alveolus
* Test Group - Free Gingival Graft + EMD (n = 22): Atraumatic extraction surgery with placement of a free gingival graft to seal the entrance of the alveolus associated with EMD in the open wound on the palate.

All surgeries will be performed by the same expert periodontist (MMVM). A blade 15c (Swann-Morton® - Sheffield, England) mounted on No. 3 scalpel handle will make an intrasulcular incision around the tooth indicated for exodontia. Then, the tooth will be extracted through the use of appropriate instruments in order to obtain a minimally traumatic exodontia. With the aim to ridge preservation after tooth extraction the socket will be sealed with a free gingival graft removed from the palate. For the free gingival graft removal, a circular template of 8 millimeters in diameter will be used. This stent has the objective of standardizing the palatal graft removal ensuring the wounds will have always the same size. After the circular incision, the graft will be removed with a thickness of 2 millimeters. After free gingival graft removal from palate, it will be adjusted to the entrance of the socket and sutured with Vicryl® 5.0 reabsorbable (Ethicon Johnsons do Brasil, São José dos Campos - SP).

After the graft position, EMD will be applied immediately after the graft removal surgical procedure on the palatal donor area, leaving it in contact with the wound for 5 min. In sequence, it will be covered with an individualized acetate plate that will extend throughout the palatal area and be in position for 2 hours after the procedure.

The evaluated clinical parameters will be: wound remaining area (WRA), scar and tissue colorimetry (TC), tissue thickness (TT) and epithelization (E). Moreover, patient-centered also will be evaluated as: number of pills (NP), tissue edema (TE), postoperative discomfort (D) and Oral Health Impact Profile (OHIP).

All data will be expressed as mean ± standard deviation (SD), and normality will be tested using the Shapiro-Wilk test. Values for remaining wound area, scar and tissue colorimetry, tissue thickness, and epithelization will be examined by repeated measures ANOVA to assess differences within and between groups, followed by a Tukey test for multiple comparisons when the value of p Shapiro-Wilk ≥ 0.05. Those with Shapiro-Wilk p values \<0.05 will be analyzed using the Friedman test (for intragroup comparisons) and Mann-Whitney tests (for intergroup comparisons). Values referring to patient-centered parameters such as postoperative discomfort, the number of analgesics taken, tissue edema and oral health impact profile measurements will be analyzed using the T-Test
