Gingival recession
Conditions
Interventions
A controlled, randomized, double-blind clinical trial will be conducted with 72 systemically healthy patients of both sexes, aged 18 or older, who have at least one unitary gingival recession type 1 (
(2) Platelet-rich fibrin (PRF), a second-generation autologous platelet concentrate that forms a fibrin matrix to support cytokine release and cell migration, enhancing soft tissue healing
and (3) Subepithelial connective tissue graft (SCTG), the SCTG is considered the gold-standard method for treating gingival recession in periodontal surgery due to its quick keratinization and adheren

Eligibility
Age
18 Years to No maximum
Inclusion criteria
Inclusion criteria: Patients at least 18 years old. Both genders. Must not have prior experience with procedures for root coverage. Diagnosed with type one (RT1) unitary gingival recession, measuring at least 1.5 mm in the presence of dentin hypersensitivity or 2 mm in its absence, with apical displacement of the gingival margin but no loss of interproximal bone tissue. Additionally, clinical detection of the cementoenamel junction on the mesial and distalsurfaces of upper or lower canines and/or premolars should not be possible. Absence of restorations or caries in the area to be treated. Healthy periodontium, characterized by probing bleeding < 10%. Probing depth of 3 mm
Exclusion criteria
Exclusion criteria: Patients with systemic diseases that may interfere with healing or periodontal health (such as diabetes, hypertension, and blood disorders, among others). Users of anticoagulant or antiplatelet drugs. Users of orthodontic appliances. Users of fixed or removable prostheses involving the canines and/or premolar teeth with gingival recession were selected for the study. Smokers; pregnant or lactating individuals. Gingival recession defects associated with dental caries lesions. Teeth with evidence of pulp pathology, molars, or teeth with severe misalignment (rotation or extrusion). Cases that do not meet the aforementioned inclusion criteria
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluate the percentage of root covering over a two-year period. This calculation will be performed by precisely measuring the residual gingival recession in treated teeth, expressed in millimeters, and subsequently transformed into a percentage representation. The main objective of the study is to conclusively identify the surgical technique that demonstrated the most optimal performance in terms of root covering. | — |
Secondary
| Measure | Time frame |
|---|---|
| Reduction of gingival recession over a two-year period after treatment, assessed through measurement in millimeters.;Increase in the width of the keratinized mucosa width over a two-year period after treatment, assessed through measurement in millimeters. ;Decrease in clinical attachment loss over a two-year period, verified through measurement of clinical insertion level in millimeters.;Increase in gingival thickness over a two-year period after treatment, assessed through measurement in millimeters. | — |
