Periodontal lateral abscess

Aetiolo& Usually a complication of advanced periodontitis. It may be due to injury to the pocket floor (?food-packing) or more virulent infection.

Pathology • Rapid acceleration of periodontal destruction.

• Destruction of epithelial pocket lining.

• Dense neutrophil infiltrate and suppuration (Fig. 43).

• Widespread osteoclastic resorption of bone (Fig. 44) increasing width and depth of pocket to form deep intrabony pocket.

• Pus may exude from pocket mouth or point on attached gingiva.
