Cementoblastoma involving the maxillary sinus.

Area of Science:

• Oral and Maxillofacial Surgery
• Pathology
• Odontogenic Tumors

Background:

• Cementoblastoma is a rare, benign odontogenic tumor originating from ectomesenchyme.
• Typically, it is associated with the roots of the mandibular first molar.

Observation:

• This report details an atypical cementoblastoma case.
• The tumor involved the roots of the maxillary first and second molars.
• It extended into the maxillary sinus and was linked to a displaced, unerupted third molar.

Findings:

• The initial clinical presentation was misleading, leading to suboptimal management.
• A definitive diagnosis was delayed by two years.
• This highlights diagnostic challenges in unusual presentations of cementoblastoma.

Implications:

• This case underscores the importance of considering rare pathologies in differential diagnosis.
• Accurate and timely diagnosis is crucial for effective management of cementoblastoma.
• Understanding atypical presentations aids in improving patient outcomes for odontogenic tumors.
