The acute lesion may be primary (a) or secondary (b) and is characterized by the presence of a focus of neutrophils (PMNs). Inflammation can be localized only within the boundaries of the affected tooth, but it is also capable of capturing adjacent teeth, surrounding their soft gum tissue, sometimes even the tissues of the opposite jaw.
