Trial Outcomes & Findings for Use of Platelet Rich Fibrin in Addition to CAF and SCTG for Treatment of Gingival Recession (NCT NCT03199118)

Subjects were selected from the outpatient clinic,Faculty of Dentistry, Cairo University between 30/09/2017 and 1/08/ 2019 Patients \>18 Periodontally and systemically healthy Miller class I or II buccal recession defects Presence of identifiable CEJ Clinical indication and/or patient request for recession coverage.

5 patients were excluded for not meeting inclusion criteria

Use of Platelet Rich Fibrin in Addition to CAF and SCTG for Treatment of Gingival Recession

measured from the cemento-enamel junction to the margin of the gingiva at the mid-buccal point of the teeth at basline, 3 months and 6 months. It is recorded in millimeters (mm) with lower values mean better outcome.

It was measured as the distance from mesial and distal papillae along the CEJ. It is recorded in millimeters (mm) where lower values means a better outcome.

(preoperative vertical recession - postoperative vertical recession/preoperative vertical recession) x 100.

measured from the gingival margin to the base of the pocket probe at the midbuccal point of the teeth. Its is recorded in millimeters (mm) where lower values mean better outcome.

measured from the CEJ to the base of the sulcus at the midbuccal point of the teeth. Its is recorded in millimeters (mm).

under local anesthesia from 3 mm below the gingival margin trans-gingivally piercing tissues horizontally, perpendicular to the long axis of the tooth until it contacts bone. Its is recorded in millimeters (mm) where higher values mean better outcome.

from the margin of the gingiva to the mucogingival junction at the midbuccal point of the teeth. Its is reported in millimeters where higher values mean better outcome.

printed yes/ no questionnaire with 3 questions: 1. would you do this surgery again? 2. would you recommend this treatment to others? 3. are you satisfied with the results?

The RES system evaluates 5 variables 6 months after surgery: Zero, 3, or 6 points are used for the evaluation of the position of the gingival margin (GM). A score of 0 or 1 point is used for each of the following variables: marginal tissue contour (MTC), soft tissue texture (STT), mucogingival junction (MGJ) alignment, and gingival color (GC). the points are then summed up to obtain one figure representing the RES. minimum value:0 maximum value: 10 which means better outcome for RES

Numerical Rating Scale (NRS) with numbers from 0 to 10 ('no pain' to 'worstpain imaginable') for the first 2 weeks postoperatively
