Diagnosis of some Bacteria Causing Gingivitis in People with Type 2 Diabetes and Investigating some of Their Biochemical and Immunological Parameters

The study aimed to isolate and identify of the types of bacteria which cause gingivitis. Gram positive bacteria were isolated by 89% more than gram-negative bacteria, 60 isolates were Streptococcus viridans and 5 isolates were Escherichia coli. The biochemical study showed a significant increase in concentration of total cholesterol (P 14"> 0.05) in the gingivitis and diabetes groups, as well as in very low density lipoproteins showed a significant increase in gingivitis and diabetes group (P 14"> 0.033), High-density lipoproteins showed a significant decrease in the group of gingivitis and diabetes compared to the control group at a significant level (P 14"> 0.018). In the immunological parameters, the results showed a significant decrease in the concentration of IL-10 in the group gingivitis and diabetes (P 14"> 0.05). The concentration of TNF- increased in gingivitis and diabetes at a significant level (P 14"> 0.05).
