    The effect of periodontal therapy on serum CRP, IL-6 levels and periodontal parameters in patients having poorly and well controlled type 2 diabetes with chronic periodontitis: A 3-month evaluation
    (2010) Dağ A.; Firat E.T.; Kadiroğlu A.K.
    Aim: To evaluate the effect of nonsurgical periodontal therapy on serum C-reactive protein (CRP), interlökin-6 (IL-6) levels and periodontal parameters in patients with poorly and well controlled type 2 diabetes with chronic periodontitis. Methods: Forty-five patients were included in the study. Of the 45, 30 had type 2 diabetes mellitus with chronic periodontitis (group 1A; poorly controlled group, n = 15, HbA1c ? 7% and group 1B; well controlled group, n = 15, HbA1c < 7%) and 15 were systemically healthy (group 2) with chronic periodontitis. Plaque index, gingival index, probing depth, clinical attachment loss, gingival bleeding index scores, serum CRP and IL-6 concentrations were measured at baseline and 3 months after the nonsurgical periodontal therapy. Results: After the nonsurgical periodontal therapy all periodontal parameters and CRP and IL-6 levels decreased significantly by the third month compared to baseline values in all groups. No statistically significant difference was determined among the groups between baseline and third-month periodontal parameters, or in CRP or IL-6 levels after nonsurgical periodontal therapy. Conclusion: Improvement in periodontal health is effective on control of systemic infection via reducing serum concentrations of CRP and IL-6 in patients with poorly and well controlled type 2 diabetes with chronic periodontitis. The effects of nonsurgical periodontal treatment seems to be independent of the degree of diabetic status. © 2010 Düzce Medical Journal.

    The effects of epidermal growth factor deficiency on rat gingival epithelia
    (2001) Ketan? M.A.; Dağ A.; Zeng?ngül A.?.; Büyükbayram H.; Özbağ D.
    Epidermal growth factor (EGF) is a low molecular mass polypeptide with 53 amino acids and is known to stimulate cell proliferation and differentiation in a wide range of tissues. EGF is thought to have important functions in epithelial growth and differentiation and in wound healing. In the present study, the teratogenic effects of sialoadenectomy on rat gingival epithelia were investigated histologically. Twenty adult female Wistar albino rats were divided into two groups (N = 10), a control and an experimental group. The experimental group was subjected to sialoadenectomy in order to create EGF deficiency. After 60 days of sialoadenectomy (EGF deficiency), control group rats were killed using pentobarbital and their maxilla removed. The sections were stained with haematoxylineosin and Mason triple for evaluation by using a light microscope. Astatistically significant reduction in body mass was noted in rats in the experimental group when compared to the control group. Decreasing the thickness of keratization layer, irregularity and disappearance of microscopic papilla, intraepithelial focal cystic lesions resulting from EGF deficiency, and a decrease in saliva, were noted. As a result, epidermal growth factor deficiency performed by sialoadenectomy caused body mass reduction and gingival epithelia abnormalities.
