Which of the following immunoglobulins is found in the highest concentration in serum samples from adult periodontitis patients with inflamed gingiva?

The correct answer is: IgG

IgG is found in the highest concentration in serum samples from adult periodontitis patients with inflamed gingiva because it is the most abundant immunoglobulin in the human body, comprising about 75% of all immunoglobulins in serum. IgA may also be found in high levels in this sample, as it is present in saliva and mucosal secretions, but it is not typically found in high concentrations in the serum. IgD and IgE are both found in very small amounts in serum and are not typically associated with periodontitis or inflamed gingiva.
