Abstract

Aim: It was aimed to evaluate gingival tissue Monocyte Chemoattractant Protein-1 (MCP-1) levels biochemically and count inflammatory cells in connective tissue and epithelium at the dentogingival junction in order to determine the relationship between inflammatory cells and gingival tissue MKP-l levels in 40 days experimental periodontitis model. Material and Methods: Thirty Wistar rats were used in the study. Fifteen rats were consisted of the experimental group and 15 served as controls. Periodontitis was created by adjusting silk ligatures to the mandibular molars in experimental group. Rats were sacrificed by cervical dislocation, gingival tissue samples were extracted from huccal region of mandibular first molars at 40 days. Histopathologically, inflammatory cells were counted in connective tissue and epithelium separately at the dentogingival junction by a light microscope transferred to a monitor with a camera apparatus. After homogenization, gingival tissue MCP-1 levels were analyzed by EEISA. Results: Numbers of lymphocytes and macrophages were significantly increased in connective tissue and epithelium at the dentogingival junction in periodontitis group than those in control group (P<0.05). Gingival tissue MCP-1 levels were significantly higher in periodontitis group (P<0.001). Conclusion: It has been concluded that infiltration of lymphocytes and macrophages in gingival tissue is related with MCP-1 expression and this expression may be an important stage of host response in periodontitis.

Özet

Amaç: Çalışmanın amacı, raflarda ligatür yardımıyla oluşturulan deneysel periodontitis modelinde biyokimyasal olarak dişeti dokusu Monosit Kemoatraktan Protein-1 (MKP-l) seviyesinin, histopatolojik olarak diş-dişeti birleşiminde bağ dokusu ve epiteldeki inflamatuar hücrelerin sayılarının belirlenerek; inflamatuar hücrelerle, dişeti dokusu MKP-l seviyesi arasındaki ilişkinin saptanmasıdır. Gereç ve Yöntem: Çalışmada 30 adet Wistar rat kullanıldı. Onbeş rat deney grubu ve 15 rat kontrol grubu olarak değerlendirildi. Periodontitis, deney grubunun mandibular molar dişlerinde ipek ligatür yardımıyla oluşturuldu. 40. günde servikal dislokasyonu takiben, mandibular I. molar dişin vestibül bölgesinden dişeti dokusu örnekleri alındı. Histopatolojik incelemede inflamatuar hücreler; dentogingival birleşim alanında bağ dokusu ve epitel dokusunda ayrı olarak, ışık mikroskobunda kamera sistemi ile görüntünün monitöre aktarılmasıyla sayıldı. Homojenize edilen dişeti dokusu örneklerinde dişeti dokusu MKP-l seviyesi ELİ S A ile tayin edildi. Bulgular: Periodontitis grubunda dentogingival birleşim alanında bağ dokusu ve epitelde lenfosit ve makrofaj sayısında kontrol grubuna oranla istatistiksel olarak anlamlı artış olduğu saptandı (P<0.05). Dişeti dokusu MKP-l seviyesinin periodontitis grubunda kontrol grubuna oranla istatistiksel olarak anlamlı yükseldiği belirlendi (P<0.00l). Sonuç: Ligatür yerleştirilerek mikrobiyal dental plak birikimi sağlanması yöntemiyle oluşturulan deneysel periodontitis modelinde dişeti dokusunda lenfosit ve makrofaj infillrasyonunun MKP-l sentezi ile ilişkili olduğu, dişeti dokusunda MKP-l sentezinin konak cevabının önemli bir aşaması olabileceği sonucune varılmıştır.
