Flashcards
Acute apical periodontitis
Acute apical periodontitis
Early infection around a tooth root tip, characterized by inflammation and a small amount of bone loss.
Chronic periapical abscess
Chronic periapical abscess
A more advanced infection around a tooth root tip, with a formed abscess cavity and thick fibrous wall.
Epithelial proliferation
Epithelial proliferation
Cells lining areas of the infection, like the tooth root tip, grow rapidly creating a layer of cells.

Study Notes
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.
