Figure 1From: Occlusal disharmony accelerates the initiation of atherosclerosis in apoE knockout ratsRepresentative results of initial stages of atherosclerosis in descending aorta. Macrophage collection (arrowheads) was observed in the control group (A) and occlusal disharmony groups (B). Scale bar = 25 μm. Percentage of total aortic lumen area occupied by plaques (mean ± SD) was significantly higher in the occlusal disharmony group than in the control group (C). ap < 0.05, vs. control group, according to t-test (n = 7).Back to article page
