Özet

Objectives: This study aims to evaluate the macroscopic andhistopathological effects of platelet-rich plasma (PRP) on healing of oralcavity wounds that were created in rats for experimental purposes. Materials and Methods: Forty-two female Wistar albino rats (age 2.5-3months; weighing 250 g - 350 g) were included in the study. Six rats wereselected for the preparation of PRP from their blood. The remaining36 rats were anesthetized and a wound was opened in their palate. Rats wererandomized into six groups. Each group contained six rats (3 for the PRP,3 for the control groups). Platelet-rich plasma was injected into the margins ofthe wounds in the PRP group. Control group did not receive any application.Six rats from the PRP and control groups were sacrificed in the first, secondand third weeks, their hard palates were photographed macroscopically,and histopathological examination was performed regarding the severity ofthe inflammation, neovascularization, fibroblast proliferation and collagenconcentration. Each parameter was statistically analyzed after scoring.Results: Although the macroscopic wound area was significantly smallerin the PRP group compared to the control group in the first and secondweeks (p 0.05).There was no statistically significant difference in the first and secondweeks regarding the severity of inflammation, while in the third week,the severity of inflammation significantly improved in the PRP groupcompared to the control group (p<0.05). In respect of neovascularization,fibroblast proliferation, and collagen concentration, there was no significantdifference between the PRP and control groups, but they showed astatistically significant increase in the PRP group compared to the controlgroup in the second and third weeks (p<0.005).Conclusion: Platelet-rich plasma application increased epithelization asa result of faster wound healing compared to regular wound healing inthe wound area. It can be concluded that PRP application has positivehistological and macroscopic effects on intraoral wound healing.

Abstract

Amaç: Bu çalışmada trombositten zengin plazmanın (TZP) sıçanlarda deneysel amaçlarla oluşturulan oral kavite yaralarının iyileşmesi üzerine makroskopik ve histopatolojik etkileri değerlendirildi. Gereç ve Yöntemler: Çalışmaya 42 dişi Wistar albino sıçanı (yaş 2.5-3 ay; ağırlık, 250 g - 350 g) dahil edildi. Altı sıçan kanlarından TZP hazırlanması için seçildi. Geriye kalan 36 sıçana anestezi yapıldı ve damaklarında yara açıldı. Sıçanlar altı gruba randomize edildi. Her grup altı sıçan içerdi (TZP grubu için 3, kontrol grubu için 3). TZP grubunda yaraların marjinlerine TZP enjekte edildi. Kontrol grubuna herhangi bir uygulama yapılmadı. TZP ve kontrol gruplarından altı sıçan birinci, ikinci ve üçüncü haftalarda sakrifiye edildi, sert damakları makroskopik olarak fotoğraf landı ve enf lamasyon şiddeti, neovaskülarizasyon, fibroblast proliferasyonu ve kolajen konsantrasyonu hakkında histopatolojik inceleme yapıldı. Her parametre skorlamadan sonra istatistiksel olarak analiz edildi. Bulgular: Makroskopik yara alanı birinci ve ikinci haftalarda TZP grubunda kontrol grubuna kıyasla anlamlı şekilde küçük iken (p 0.05). Enf lamasyon şiddetinde birinci ve ikinci haftalarda istatistiksel olarak anlamlı farklılık yoktu, fakat üçüncü haftada enf lamasyon şiddeti TZP grubunda kontrol grubuna kıyasla anlamlı şekilde iyileşti (p<0.05). Neovaskülarizasyon, fibroblast proliferasyonu ve kollajen konsantrasyonu açısından TZP ve kontrol grupları arasında anlamlı farklılık yoktu, fakat bunlar ikinci ve üçüncü haftalarda TZP grubunda kontrol grubuna kıyasla istatistiksel olarak anlamlı artış gösterdi (p<0.005). Sonuç: Trombositten zengin plazma uygulaması yara alanında sıradan yara iyileşmesine göre daha hızlı yara iyileşmesi sonucunda epitelizasyonu artırdı. TZP uygulamasının intraoral yaraların iyileşmesinde pozitif histolojik ve makroskopik etkileri olduğu sonucuna varılabilir.
