Clinical Trial Summary
The aim of this study was to treat the areas with Miller Class I bilateral multiple gingival
recession in the maxillary teeth using the Titanium Platelet-Rich Fibrin (T-PRF), an
autogenous biomaterial applied in combination with a Modified Coronally Positioned Flap
(MCPF) prepared using microsurgical techniques, and the gold standard Subepithelial
Connective Tissue Graft (SCTG), to evaluate the efficacy of the treatments and to compare the
clinical results 6 months after the treatment.

AİM:
The aim of this study was to treat the areas with Miller Class I bilateral multiple gingival
recession in the maxillary teeth using the Titanium Platelet-Rich Fibrin (T-PRF), an
autogenous biomaterial applied in combination with a Modified Coronally Positioned Flap
(MCPF) prepared using microsurgical techniques, and the gold standard Subepithelial
Connective Tissue Graft (SCTG), to evaluate the efficacy of the treatments and to compare the
clinical results 6 months after the treatment.
MATERIALS AND METHODS A total of 20 patients (118 defects), consisting of 13 females and 7
males, with maxillary bilateral Miller Class I gingival recession who were aged between 18
and 65, applied to Necmettin Erbakan University, Faculty of Dentistry, Department of
Periodontology and had aesthetic anxiety and sensitivity problems due to multiple gingival
recessions were included in our study. As a randomized controlled clinical trial, in the
patients' bilateral recession sites, while gingival recessions of one group were treated with
T-PRF, the gingival recessions of the other group were treated with SCTG using a simple
randomization method. The study protocol was in accordance with the Declaration of Helsinki
of 1975, as revised in 2002 and was submitted to and approved by the ethical committee of
Necmettin Erbakan University and the Ministry of Health General Directorate of Health
Services (protocol number:2019/238). All patients included in the study were given detailed
information about the clinical trial, and their written informed consent was obtained. The
study was performed between January 2019 and November 2020 in Necmettin Erbakan University
Department of Periodontology.
The individuals were divided into 2 groups in accordance with the study protocol:
Group1: SCTG group (n=60) Group2: T-PRF group (n=58) The criteria for inclusion in the study
were determined as systemically and periodontally healthy volunteers between the ages of
18-65, the absence of parafunctional habits, non-smoking, the presence of Miller Class I
gingival recession defect in teeth located in the bilateral maxillary region, the absence of
any hard tissue defects in the relevant region and the absence of a restorative, endodontic
procedure or periodontal surgical intervention, a full-mouth plaque score (FMPS) of ≤ 25%,
having a marginal gingival thickness of at least 1 mm in the area with gingival recession,
the absence of a shallow hard palate dome, having a soft tissue thickness of at least 3 mm,
the absence of torus in the area where the graft was taken, the absence of any systemic
disease, not using antibiotics for any reason in the last 6 months, the presence of at least
20 teeth in the mouth, not being pregnant and breastfeeding, and patients who applied to the
periodontology clinic with various periodontal problems and were indicated for connective
tissue graft operation due to gingival recession. The individuals who were outside the
exclusion criteria and did not agree to participate in the study were excluded from the
study.
In the study with a sample size of 118, the effect size value (G * Power 3.1 for Windows)
calculated based on the power (1-β err probe) = 95% and α = 5% t-test was determined as 0.334
for the analysis of repeated measurements.
