Platelet Rich Fibrin on Root Coverage of Gingival Recessions
- Conditions
- Gingival Recession
- Interventions
- Other: Platelet rich fibrin
- Registration Number
- NCT04248049
- Lead Sponsor
- Universidad Antonio Nariño
- Brief Summary
Several surgical techniques and various adjunctive agents have been used to covered Gingival Recession (GR) and promote clinical outcomes. The treatment of the GR more used (gold standard) is the root coverage with surgical procedures and connective tissue graft, but it has limitations due to the conditions of the donor graft. Is necessary develop other biomaterials for these cases.
The platelet rich fibrin is a autologous biomaterial that has gained tremendous momentum having been utilized for a variety of dental and medical procedures including periodontal surgeries. However, results remain contradictory and mainly focus on the hard and soft tissue healing, aesthetics and postoperative discomfort.
The objective of this study was to evaluate the clinical effects of coronal advanced flap (CAF) and CAF + Platelet Rich Fibrin (PRF) on Root coverage (RC) over a period of 24 month.

Group Intervention Description Control side Platelet rich fibrin Roots covered with coronally advanced flap (CAR) Experimental side Platelet rich fibrin Roots covered with coronally advanced flap (CAF) and platelet rich fibrin (PRF) (CAF+PRF)
- Primary Outcome Measures
Name Time Method Change of percentage of root coverage (PRC) from baseline at 12 and 24 months baseline, 1, 3 , 6, 9, 12 and 24 months Complete root coverage after surgical correction measured in percentage by using periodontal probe.
PRC= Preoperative recession depth - Postoperative recession depth X 100 % Preoperative recession depth
- Secondary Outcome Measures
Name Time Method Probing depth (PD) baseline, 1, 3 , 6, 9, 12 and 24 months It is measuring the distance from the gingival margin to the base of the pocket using periodontal probe. The probe will be inserted parallel to the long axis of the tooth using light force. (measured using a periodontal probe in millimeters).
Gingival bleeding index (IS) baseline, 1, 3 , 6, 9, 12 and 24 months Evaluation of the presence and absence of bleeding in the gingival margin through the gingival sulcus. The index is calculated after penetration of the sulcus by the periodontal probe, bleeding surfaces are noted and then counted. The index is calculated by dividing the number of surfaces that bleed by the total number of teeth and then multiplying by 100 to reach the percentage of bleeding index.
Vertical gingival recession (VGR) baseline, 1, 3 , 6, 9, 12 and 24 months It is measuring the distance from the cemento-enamel junction (CEJ) to the margin of the gingiva at the midbuccal point of the teeth (measured using a periodontal probe in millimeters).
Clinical attachment level(CAL) baseline, 1, 3 , 6, 9, 12 and 24 months Two measurements will be used to calculate the CAL: the probing depth and the distance from the gingival margin to the CEJ.
Gingival tissue thickness baseline, 1, 3 , 6, 9, 12 and 24 months The gingiva mid-buccally in the attached gingiva will be penetrated with an endodontic reamer with a silicon disc stop. The measure of penetration will be measured with dentimeter (mm).
Horizontal gingival recession (HGR) baseline, 1, 3 , 6, 9, 12 and 24 months Measured horizontally between two borders of the recession. (measured using a periodontal probe in millimeters).
Visual analog scale (VAS) baseline, 1, 3 , 6, 9, 12 and 24 months Visual analog scale
Evaluation of oral health impact on quality of life, using the Oral Health Impact Profile (OHIP-14) questionnaire. baseline, 1, 3 , 6, 9, 12 and 24 months Evaluate the impact of oral health on patient's quality of life before and 1 year after implant installation. This evaluation will be carried out through the application of a questionnaire with 14 questions (Oral Health Impact Profile: OHIP-14) that assess the patient's perception regarding the impact of oral conditions on their well-being
Keratinized tissue height (KTH) baseline, 1, 3 , 6, 9, 12 and 24 months To measure the tissue thickness, a guiding device will be made to standardize the region to be measured and then, at a specific point, the mucosa will be punctured with an endodontic spacer and the thickness marked with a rubber marker. Then, using a digital caliper, the thickness will be measured.
