Periostitis ossificans in a 10-year-old child

Area of Science:

• Pediatric Dentistry
• Oral and Maxillofacial Surgery
• Endodontics

Background:

• Periostitis ossificans (PO) is an osteomyelitis variant originating from odontogenic infections, primarily affecting children and adolescents.
• PO often results in the loss of the affected tooth, necessitating alternative treatment strategies.

Observation:

• A 10-year-old patient presented with mandibular asymmetry and signs of infection in tooth 36.
• Radiographic and CT imaging revealed characteristic onion-skin periosteal bone proliferation in the mandible.

Findings:

• Endodontic treatment of tooth 36, including root canal preparation and calcium hydroxide medication, was performed.
• Complete remission of periostitis ossificans was achieved within 14 months post-treatment.

Implications:

• Endodontic intervention presents a less invasive treatment option for pediatric periostitis ossificans.
• This approach can effectively manage the condition and minimize the risk of tooth loss in pediatric patients.
