Xenogenous Collagen Matrix Graft With or Without Enamel Matrix Proteins Derivative for Root Coverage

Xenogenous Collagen Matrix Graft Associated or Not With Enamel Matrix Derivative Proteins in the Treatment of Gingival Recession Class I and II of Miller: Randomized Controlled Clinical Study

The purpose of this study is to evaluate the reduction of gingival recession of single Miller Class I and II defects treated by coronally advanced flap with subepithelial porcine collagen matrix graft and / or enamel matrix proteins.

Inclusion Criteria:

• Age ≥ 18 years.
• Presence of at least one Class I or II Miller gingival recession ≥ 2.5 mm in maxillary canines or premolars with identifiable cementum-enamel junction (CEJ) and without deep non-carious cervical lesions (< 0.5 mm): A +(Pini-Prato et al. 2010).
• Aesthetic complaint and/or presence of dentin hypersensitivity to air stimulus.
• Full-mouth visible plaque index ≤ 20% (Ainamo & Bay 1975).
• Full-mouth sulcus bleeding index ≤ 20% (Mühlemann & Son 1971).

Exclusion Criteria:

• Smoking.
• Pregnancy.
• Presence of systemic disorders (diabetes, hypertension, heart disease or any other condition that could contraindicate periodontal surgery).
• Use of medications (immunosuppressants, phenytoin or anything else that might affect mucosal healing and repair).
• Previous periodontal surgery in the area.
