Area of Science:

  • Pediatric Dentistry
  • Developmental Biology
  • Oral Pathology

Background:

  • Regional odontodysplasia (RO) is a rare anomaly affecting dental development.
  • It involves both ectodermal and mesodermal components in contiguous teeth.
  • RO typically presents localized in one arch, affecting primary and permanent dentitions.

Purpose of the Study:

  • To report a rare case of regional odontodysplasia in a pediatric patient.
  • To describe the clinical and radiographic features of this anomaly.
  • To discuss the management and future treatment considerations for RO.

Main Methods:

  • Case report of a 5-year-old girl with RO.
  • Clinical examination and radiographic assessment.
  • Management with temporary partial acrylic denture and follow-up.

Main Results:

  • The patient presented with RO affecting the left maxillary arch, crossing the midline.
  • Affected teeth exhibited abnormal morphology, softness, discoloration, and a radiographic "ghostlike" appearance.
  • Primary teeth were missing due to prior extractions; permanent teeth showed the characteristic radiographic findings.

Conclusions:

  • This case adds to the understanding of RO in pediatric dentistry.
  • Early diagnosis and appropriate management are crucial for affected children.
  • Future treatment may involve extraction of permanent teeth and dental implant rehabilitation.
