Objective: Inflammatory periodontal diseases may be associated with common systemic conditions and, as recently described, alterations in lipid levels in the blood. The aim of this study was to determine the possible effects of apolipoprotein E (ApoE) genotypes on the lipid levels in healthy people and patients with chronic periodontitis (CP) in relation to periodontopathic bacteria
Results: There was no evidence for a significant association between ApoE gene polymorphisms and CP (P > 0.05). Patients with CP had increased levels of total cholesterol and low-density lipoprotein (LDL) compared to controls (P < 0.05); however, no significant difference was found for triglyceride and high-density lipoprotein (HDL) levels. ApoE gene variability influenced LDL levels marginally (P = 0.08) but it did not modify total
