Large erupted complex odontoma mimicking maxillary osteomyelitis.

Area of Science:

• Dentistry
• Oral Pathology
• Radiology

Background:

• Odontomas are the most common benign odontogenic hamartomas, typically presenting in the second decade of life.
• Complex odontomas, a subtype, are characterized by a disorganized mass of dental hard tissues.
• While often asymptomatic, odontomas can cause complications when erupting or associated with impacted teeth.

Observation:

• A case report of a male patient in his early 60s presenting with a large, solitary sclerotic complex odontoma.
• The odontoma was located in the middle and posterior maxilla, had erupted into the oral cavity, and communicated with the right maxillary sinus.
• The lesion's delayed presentation, significant size, specific location, and active suppuration were notable features.

Findings:

• The complex odontoma was a substantial, sclerotic mass of dental origin.
• Radiographic and clinical findings indicated eruption into the oral cavity and communication with the maxillary sinus.
• The patient's advanced age and the lesion's characteristics presented atypical features for a typical odontoma presentation.

Implications:

• This case underscores the importance of considering odontomas in the differential diagnosis of maxillofacial lesions, even in older adults.
• The unusual presentation of this complex odontoma highlights potential diagnostic challenges for clinicians due to delayed eruption and sinus involvement.
• Understanding the varied presentations of odontomas is crucial for accurate diagnosis and appropriate management of these benign odontogenic tumors.
