Summary
A rare dental anomaly in a child presented as a missing primary molar, revealing a cystic lesion. Surgical removal confirmed a hyperplastic dental follicle, possibly an early adenomatoid odontogenic tumor.
Area of Science:
- Dentistry
- Oral Pathology
- Pediatric Dentistry
Background:
- Congenital absence of primary teeth can be associated with developmental abnormalities.
- Odontogenic tumors are a diverse group of neoplasms arising from tooth-forming tissues.
Observation:
- A 6-year-old female presented with a clinically absent mandibular second primary molar.
- Radiographs showed a radiolucent lesion around the unerupted tooth, with displacement of the permanent premolar.
- The lesion was surgically removed along with the unerupted teeth.
Findings:
- Histopathology revealed a hyperplastic dental follicle.
- Focal proliferation of odontogenic epithelium and duct-like structures were noted.
- The findings were consistent with an incipient adenomatoid odontogenic tumor.
Implications:
- This case highlights the importance of radiographic examination in diagnosing developmental dental anomalies.
- Early detection and surgical management are crucial for favorable outcomes.
- Understanding the histopathological features aids in differentiating benign conditions from early-stage tumors.
