Cementoblastoma Solely Involving Maxillary Primary Teeth--A Rare Presentation

Area of Science:

• Oral pathology
• Odontogenic neoplasms
• Dental radiology

Background:

• Cementoblastoma is a rare, benign neoplasm originating from odontogenic ectomesenchyme, typically affecting tooth roots.
• It predominantly occurs in the second and third decades of life, with rare reports involving primary teeth or the maxilla.

Observation:

• A rare case of cementoblastoma in a ten-year-old boy presenting with a maxillary posterior swelling is discussed.
• Initial radiographic findings mimicked an odontoma, necessitating further diagnostic evaluation.
• The lesion involved the roots of a tooth in the transitional dentition.

Findings:

• The final diagnosis was confirmed as cementoblastoma.
• The study advocates for the use of polarized microscopy to support histopathological diagnosis, particularly regarding its cemental origin.
• Radiographic features can be misleading, resembling other radio-opaque lesions.

Implications:

• Cementoblastoma should be included in the differential diagnosis for radio-opaque lesions in the transitional dentition.
• Early and accurate diagnosis is crucial for appropriate management of cementoblastoma.
• This case expands the understanding of cementoblastoma presentation in pediatric patients.
