Description

This detailed anatomical illustration depicts an acute apical abscess affecting a lower molar, presented in a sagittal section. The image clearly shows a necrotic pulp chamber filled with darkened, decayed tissue extending through the root canal. The abscess cavity appears slightly elevated, with visible compression of nearby structures, and the cortical plate is beginning to thin. This visual effectively captures the acute stage of infection with clear contrast between healthy, inflamed, and purulent regions.
