Synonym(s): Chronic ossifying alveolar periostitis, pseudo-odontoma, dental lumps, eruption cysts

Contributor(s): Gordon Baker, Jill Richardson, Bayard A Rucker

Introduction

  • A description of the cain of inflammatory changes that occur in perialveolar osseous tissues.
  • It has also been descirbed as chronic ossifying periostitis, pseudo-odontoma and eruption cysts depending on etiology, location and nature of inflammatory response seen in the tissues.
  • Cause: benign inflammatory response to eruption of permanent teeth; term is also used to describe pathologic inflammation around the tooth root associated with periodontal disease   Teeth: periodontal disease  and dental decay   Teeth: caries - infundibular cement  .
  • Signs: swelling along the vertical border of the mandible ('bumps'); signs associated with periodontal disease.
  • Diagnosis: palpable lumps along the horizontal border of the mandible.
  • Treatment: none for benign condition; as for periodontal disease.
  • Prognosis: good. Some swelling may persist.

Pathogenesis

Etiology

  • Direct dental trauma and dentistogenic injury or maxillary/mandibular bone trauma and infections around reserve crowns and tooth roots.

Specific

  • Overcrowding of unerupted teeth.

Pathophysiology

Benign
  • Active dental sac during eruption of permanent premolars and molars   →   benign inflammation of the alveolar bone (periostitis)   →   focal enlargements along the ventral mandible.
  • With completion of eruption, active inflammation resolves   →   residual swelling due to new bone formation.
