    The Adjunctive Effect of Platelet-Rich Fibrin to Connective Tissue Graft in the Treatment of Buccal Recession Defects: Results of a Randomized, Parallel-Group Controlled Trial
    (Wiley, 2015) Keçeli, Hüseyin Gencay; Kamak, Gülen; Erdemir, Ebru Olgun; Evginer, Mustafa Serdar; Dolgun, Anıl
    Background: Platelet-rich fibrin (PRF) is an autologous preparation that has encouraging effects in healing and regeneration. The aim of this trial is to evaluate the effectiveness of coronally advanced flap (CAF) + connective tissue graft (CTG) + PRF in Miller Class I and II recession treatment compared to CAF + CTG. Methods: Forty patients were treated surgically with either CAF + CTG + PRF (test group) or CAF + CTG (control group). Clinical parameters of plaque index, gingival index, vertical recession (VR), probing depth, clinical attachment level (CAL), keratinized tissue width (KTW), horizontal recession (HR), mucogingival junction localization, and tissue thickness (TT) were recorded at baseline and 3 and 6 months after surgery. Root coverage (RC), complete RC (CRC), attachment gain (AG), and keratinized tissue change (KTC) were also calculated. Results: All individuals completed the entire study period. At baseline, mean VR, HR, CAL, KTW, and TT values were similar (P > 0.05). In both groups, all parameters showed significant improvement after treatment (P < 0.001), and except TT (P < 0.05), no intergroup difference was observed at 6 months after surgery. The amount of RC and AG, but not KTC and CRC, was higher in the PRF-applied group (P < 0.05). Conclusions: According to the results, the addition of PRF did not further develop the outcomes of CAF + CTG treatment except increasing the TT. However, this single trial is not sufficient to advocate the true clinical effect of PRF on recession treatment with CAF + CTG, and additional trials are needed.

    Comparison of two techniques in gingival recession treatment A randomized one-year clinical follow-up study
    (Wroclaw Medical Univ, 2022) Evginer, Mustafa Serdar; Olgun, Ebru; Parlak, Hanife Merva; Dolgun, Anil Barak; Keceli, Huseyin Gencay
    Background. Gingival recession (GR) is highly prevalent in the general population and represents a significant concern for patients and clinicians. Various surgical techniques have been proposed to treat gingival recession. Well-designed trials with clinician-and patient-based parameters, evaluating the envelope connective tissue graft (E-CTG) and semilunar coronally advanced flap (SCAF) techniques are still needed. Objectives. The aim of this trial was to compare the effectiveness of E-CTG and SCAF in the treatment of GR during a 1-year follow-up. Material and methods. A total of 42 patients with GR were treated with E-CTG (n = 20) or SCAF (n = 22). Clinician-based recordings of recession depth (RD), recession width (RW), probing depth (PD), clinical attachment level (CAL), keratinized tissue width (KTW), tissue thickness (TT), clinical attachment gain (CAG), root coverage (RC), keratinized tissue change (KTC), and wound healing index (WHI), as well as patient-based parameters of dentine hypersensitivity (DH), tissue appearance, patient expectations, and esthetics were collected at baseline (BL), 6 weeks (T1), 6 months (T2), and 1 year (T3). Results. After the treatment, E-CTG demonstrated better outcomes than SCAF in terms of CAG (50.70% vs. 33.33%), RC (85.60% vs. 35.60%) and KTC (1.70 +/- 1.49 mm vs. 0.36 +/- 0.96 mm) at T3. Similar findings were detected in terms of WHI, tissue appearance, patient expectations, and esthetics. Although inconvenient surgical experience was recorded, better results were obtained after E-CTG in terms of DH and meeting the RC expectations. Conclusions. Despite it being more difficult surgical experience and the risk of keloid formation, E-CTG was superior to SCAF in terms of RC percentage, reducing DH and obtaining satisfactory RC. However, it is still necessary to improve patient comfort in the case of E-CTG.

    Sığ miller sınıf I dişeti çekilmelerinde zarf tekniği ve semiluner koronale pozisyone flep tekniklerinin kök kapanması ve keratinize diş eti dokusu kazanımı düzeyine olan etkilerinin karşılaştırmalı olarak incelenmesi
    (Kırıkkale Üniversitesi, 2015) Evginer, Mustafa Serdar; Erdemir, Hatice Ebru Olgun; Özcan, Gönen
    Bu klinik çalışmanın amacı sığ dişeti (? 3mm) çekilmesi olan bireylerde zarf tekniği ile semiluner koronale pozisyone flep (SKPF) yönteminin kök kapanması, ataçman ve keratinize dişeti kazanımı ile hasta konforu açısından 1 senelik takip sürecinde karşılaştırmaktır. Ayrıca işlem ve takip süresi sonrasında bütün hastalara işlem sonrası kole hassasiyetinde azalma, hastaların post-operatif olarak işlemden memnuniyetleri ile iyileşme sürecinde ağrı ve konforları hakkında bilgileri elde edilmesi adına sayısal değerler verilmesi istendi. Çalışmaya toplamda 42 hasta dahil edilmiş olup zarf grubunu 20 hasta, SKPF grubunu 22 hasta oluşturmuştur. Yapılan klinik ölçümler ve cerrahi işlemler sonrası hastalar 6 hafta, 6 ay ve 12 ay sonrasında tekrar değerlendirildiğinde zarf grubunda %86 kök kapanma yüzdesi elde edilirken bu durum SKPF grubunda %48 olarak tespit edilmiştir. Ataçman kazanımı yönünden değerlendirildiğinde 1 senenin sonunda zarf ve SKPF grubunda sırasıyla %57 ve %33 operasyon başlangıcına göre değişim görülmüştür. Keratinize dişeti kazanımı bakımından zarf grubundan 1,70±0,70 mm kazanım görülürken, bu oran SKPF grubunda 0,37±0,07 mm' de kalmıştır. Operasyonel memnuniyet ve köle hassasiyeti değerlendirildiğinde zarf grubundaki hastaların SKPF grubuna göre daha iyi skor verdikleri tespit edilmiştir. Çalışmanın sonucunda sınıf Miller I sığ dişeti çekilmelerinde hem zarf tekniğinin hem de SKPF tekniğinin başarıyla uygulanabildiği, damaktan doku alınmadığı için SKPF grubunun operasyonel memnuniyeti daha iyi olsa da genel memnuniyet, hassassiyetin giderilmesi gibi diğer subjektif parametreler açısından zarf yönteminin daha avantajlı olduğu bulunmuştur.
