Summary
Chronic osteomyelitis with proliferative periostitis, a condition causing new bone growth, typically affects young patients' mandibles due to dental infections. This case highlights an unusual presentation linked to a developing third molar.
Area of Science:
- Oral and Maxillofacial Surgery
- Pathology
- Infectious Diseases
Background:
- Chronic osteomyelitis with subperiosteal new bone formation is a periosteal reaction to chronic inflammation or infection.
- In the maxillofacial region, this condition has been termed Garrè's osteomyelitis or periostitis ossificans.
- The term 'Garrè's osteomyelitis' is increasingly considered a misnomer, with 'chronic osteomyelitis with proliferative periostitis' being more accurate.
Observation:
- This condition commonly affects the mandible in young individuals.
- It is typically secondary to a dental infection.
- This report details an unusual case in a 12-year-old patient with mandibular involvement.
Findings:
- The source of infection in this unusual case was identified as a developing lower left third molar.
- Notably, the third molar appeared to have no direct communication with the oral cavity.
- This presentation deviates from the typical etiology of dental infection.
Implications:
- Accurate terminology is crucial for understanding and managing this pathology.
- Early diagnosis and intervention, including source removal and antibiotics, are key.
- This case underscores the importance of considering atypical sources of infection in pediatric mandibular osteomyelitis.

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
