Study Notes
Common Pathologic Conditions of the Jaws
- The most common pathologic condition of the jaws is dental abscesses.
- Direct pathways for infectious and inflammatory agents to invade bone include periodontal disease and dental caries.
Inflammatory Response
- Injuries stimulate an inflammatory response aimed at isolating the injury and creating an environment conducive to tissue repair.
- This response depends on factors including the nature and extent of the injury, as well as the individual's immune response.
Specific Inflammatory Lesions
- Apical periodontitis involves inflammation specifically around the apex of a tooth.
- Cellulitis extends to the overlying soft tissue from an infection.
- Diffuse sclerosing osteomyelitis is common in the posterior mandibular area, characterized by intermittent swelling and extraoral drainage.
- A periapical granuloma exhibits a focal reaction often due to a long-standing infection paired with high tissue resistance.
Osteomyelitis and Radiographic Features
- Chronic osteomyelitis is characterized radiographically by a moth-eaten appearance.
- The primary clinical symptom of acute osteomyelitis includes localized pain and swelling.
- Osteoradionecrosis has a radiographic appearance characterized by radiolucency, typically seen post-radiation therapy.
Conditions Related to Medication and Inflammation
- Medication-related osteonecrosis of the jaw (MRONJ) results in progressive bone destruction linked to antiresorptive and antiangiogenic treatments.
- Chronic dentoalveolar abscesses typically feature pus formation and can create a large area of communicate infection.
Clinical Features and Symptoms
- Symptoms of pericoronitis include pain, swelling, and difficulty in opening the mouth.
- Chronic apical periodontitis displays mild pain or may be asymptomatic.
Radiographic Characteristics
- Radiographically, chronic suppurative osteomyelitis shows mixed radiolucent and radiopaque areas.
- In chronic sclerosing osteomyelitis, new bone formation may present initially as a thin radiopaque line parallel to the bone surface, later evolving to an onion skin appearance.
Aims of Radiographic Interpretation
- Tutorials on radiographic interpretation of inflammatory lesions aim to develop diagnostic skills and understanding of various lesions' manifestations.
- Objectives include identifying radiographic features associated with specific inflammatory conditions for accurate diagnosis and management.
Additional Notes on Conditions
- Cystic degeneration can complicate long-standing periapical granulomas.
- Pre-existing periodontal disease may predispose individuals to osteomyelitis.
- Chronic with proliferative periostitis, also known as Garre’s osteomyelitis, typically leads to new bone formation around the affected area.
