Dental Pathology Quiz: Periapical Conditions

What is primarily observed around the apex of a non-vital tooth in acute apical periodontitis?

Which characteristic radiographic finding is associated with acute apical periodontitis?

What type of inflammatory cells predominantly infiltrate the fibrous wall of a chronic periapical abscess?

What may result from epithelial proliferation in an apical granuloma?

Which condition is characterized by an infection spreading through tissues and a dense infiltrate of neutrophils and fibrin exudate?

Acute Apical Periodontitis

Inflammatory cells, mainly neutrophils, clustered around the apex of a non-vital tooth.
Inflammatory cells spreading into bone.
Minimal bone resorption.
Radiographically, slight fuzziness of the apical lamina dura.

Chronic Periapical Abscess

Abscess cavity at the apex of a non-vital tooth.
Thick fibrous wall surrounding the cavity.
Primarily neutrophils infiltrating the wall.

Epithelial Proliferation in Apical Granuloma

Odontogenic epithelium proliferation in response to inflammation.
Epithelial proliferation within the rests of Malassez in the periodontal ligament.
Cyst formation is a possible outcome.

Pre-Apical Granuloma

Epithelial cords started proliferation.
Proliferation inside pre-iapical granuloma.
Capsule

Cholesterol Clefts in Periapical Cyst

Lumen filled with cholesterol clefts.
Crystals form in the fibrous wall.
Epithelium overlying the focus breaks down.
Cholesterol leaks into the cyst lumen.

Cellulitis

Infection spreading through tissues.
Dense infiltrate of neutrophils, macrophages, and fibrin.
Separating muscle bundles in facial muscle.
Muscle bundles are usually tightly packed.
