Abscess of periodontium

—Gingival abscess

1. Clinically- erythematous, smooth, sometimes painful, and fluctuant swelling.
2. What this type of disease would look like radiographically - no changes
3. Specific organism associated with the disease - From bacteria that it carried deep into the tissue when a foreign substance such as toothbrush bristles forces the bacteria into the gingiva.
4. How would you diagnosis this- what would your differential diagnosis be? This abscess is localized and an acute inflammatory lesion. This lesion can occur due to microbial plaque infection, trauma, and foreign body impaction.

—Periodontal abscess

—1. Clinically- localized accumulation of pus within the gingival wall of a periodontal pocket (purulent eudate). The gingiva is edematous, erythematous, smooth, and shiny.
2. What this type of disease would look like radiographically- Early periodontial abscess present no radiographic changes. Periodontial abscess usually show on the radiographs as a radiolucent area long the lateral surface of the root of the tooth.
3. Specific organism associated with the disease- The microorganisms are primarily gram-negative anaerobic rods.
4. How would you diagnosis this- what would your differential diagnosis be? This lesion is found in patients with untreated periodontitis and related to moderate to deep periodontal pockets. Periodontal abscess are mainly related to incomplete calculus removal in clinical situations. Periodontal abscesses are linked to periodontal surgery, after preventive maintenance, after systemic antibiotic therapy, and as a result of recurrent disease. They can also be caused by tooth perforation or fracture and foreign body impaction. Patients with diabetes mellitus that is poorly controlled can be a predisposing factor as well.

—Periocoronal abscess

1. Clinically- result from inflammation of soft tissue operculum, which covers partially erupted tooth. Most often are found around mandibular third molars. The inflammation may be caused by retention of plaque, food, or trauma. Clinically - mild discomfort, swelling of tissue, tenderness, erythema, swelling of cheek, and systemic complications such as fever and malaice. Some patients posess no clinical signs or symptoms, however the gingival flap is often chronically inflamed and infected and has ulcerations along the inner surface.
2. What this type of disease would look like radiographically - no changes.
3. Specific organism associated with the disease - dental plaque, food impaction, trauma
4. How would you diagnosis this - what would your differential diagnosis be? Diagnose by clinical examination and symptoms.
