Abstract
Amaç: Mevcut çalışmanın amacı, kurkumin içeren ve içermeyen oral filmlerin dişeti yara yeri iyileşmesine olan etkilerini klinik olarak ve TNF-alfa, IL-10, VEGF, alfa-SMA değerleri üzerine etkisini incelemektir. Materyal ve Metot: Çalışmaya 72 erkek Wistar Albino sıçan dahil edildi. Sıçanlar rastgele kontrol (K), deney (D) ve film (F) grubu olmak üzere üç eşit gruba ayrıldı. Genel anestezi altında tüm sıçanlara, damak bölgelerinde 4 mm çapında yara yeri oluşturuldu. K grubunda yara alanı boş bırakıldı. Çalışma sonuna kadar D grubuna kurkumin içeren, F grubuna ise kurkumin içermeyen oral film uygulandı. 3., 7., 14. ve 21. günlerde yara alanları ölçümleri IMAGEJ programı ile karşılaştırıldı. İlgili günlerde biyokimyasal değişimleri değerlendirmek amacıyla alınan doku örneklerinde, TNF-alfa, IL-10, VEGF ve alfa-SMA (ACTa-2) parametrelerinin qRT-PCR ile gen ekspresyon analizi, ELISA ile protein ekspresyonu tayini yapıldı. Veriler istatistiksel olarak değerlendirildi. Bulgular: Yara alanları K ve F grubu ile karşılaştırıldığında D grubunda 3., 7. ve 14. günlerde anlamlı şekilde azaldığı gözlendi (p<0.05). qRT-PCR gen ekspresyonu analizinde; 3. günde TNF-alfa D grubunda istatistiksel anlamlı olarak diğer gruplardan daha düşük bulunmuştur. 3. günde D ve F gruplarında VEGF değeri K grubundan istatistiksel olarak anlamlı yüksektir. 3.günde F grubunda IL-10 değeri istatistiksel olarak anlamlı yüksektir. Alfa-SMA (ACTa-2) açısından, 3. günde D ve F gruplarında K grubuna kıyasla, 7. ve 14. günlerde ise D grubu K grubuna kıyasla istatistiksel olarak anlamlı yüksek bulunmuştur. 21. günde ise gruplar arasında istatistiksel anlamda fark bulunmamıştır. Protein ekspresyonu açısından gruplar arasında istatistiksel olarak anlamlı farklılık yoktur. Sonuçlar: Çalışmanın sınırları dahilinde bulgularımız kurkumin içeren oral filmin erken dönemde periodontal yara iyileşmesini hızlandırabileceğini göstermiştir. Kurkumin içeren filmin, periodontal dokular üzerine etkisinin değerlendirildiği uzun dönem klinik çalışmalara ihtiyaç duyulmaktadır. Anahtar Kelimeler: Yara iyileşmesi, kurkumin, HPMC, oral film
Objective: The aim of the present study was to clinically evaluate the effects of curcumin-containing and curcumin-free oral films on gingival wound healing and to investigate their effects on TNF-alpha, IL-10, VEGF, and alpha-SMA levels. Materials and Methods: A total of 72 male Wistar Albino rats were included in the study. The rats were randomly divided into three equal groups: control (K), experimental (D), and film (F). Under general anesthesia, a 4 mm diameter wound was created in the palatal region of all rats. In the K group, the wound area was left untreated. Throughout the study period, a curcumin-containing oral film was applied to the D group, while a curcumin-free film was applied to the F group. Wound areas were measured using the IMAGEJ software on days 3, 7, 14, and 21. To assess biochemical changes, tissue samples collected on the respective days were analyzed for TNF-alpha, IL-10, VEGF, and alpha-SMA (ACTa-2) via qRT-PCR for gene expression and ELISA for protein expression. Data were analyzed statistically. Results: Wound areas in the D group were significantly reduced on days 3, 7, and 14 compared to the K and F groups (p<0.05). In the qRT-PCR gene expression analysis, TNF-alpha levels were significantly lower in the D group on day 3 compared to the other groups. On day 3, VEGF levels in the D and F groups were significantly higher than in the K group. IL-10 expression was significantly higher in the F group on day 3. Regarding alpha-SMA (ACTa-2), expression was significantly higher in the D and F groups compared to the K group on day 3, and in the D group compared to the K group on days 7 and 14. No statistically significant differences were observed between the groups on day 21. In terms of protein expression, no statistically significant differences were found among the groups. Conclusion: Within the limitations of this study, our findings suggest that curcumin-containing oral films may accelerate early-stage periodontal wound healing. Further long-term clinical studies are needed to evaluate the effects of curcumin-containing films on periodontal tissues. Keywords: Wound healing, curcumin, HPMC, oral film.
