Summary
This case study details a rare dental anomaly where a third molar fused with a supernumerary fourth molar caused recurrent infections. Surgical extraction successfully resolved the patient's inflammatory issues.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
Background:
- Dental anomalies are classified into groups including anomalies of volume, number, form, position, and union.
- Anomalies of union include fusion, gemination, concrescence, coalescence, and anchylosis.
- Gemination, a rare union anomaly with 0.5% prevalence, typically affects anterior teeth but can occur in bicuspids and molars.
Observation:
- A 19-year-old male presented with recurrent inflammatory episodes in the left retromolar area.
- The patient had a semi-impacted lower third molar fused with a supernumerary fourth molar.
- Radiographic studies confirmed shared roots, crown, pulp chambers, and canals between the two teeth.
Findings:
- The fused dental anomaly presented as a rare case of gemination involving a third and a supernumerary fourth molar.
- The condition led to recurrent periapical inflammation and infection, necessitating intervention.
- Surgical extraction of the semi-impacted third molar was performed under local anesthesia.
Implications:
- This case highlights the importance of recognizing and managing rare dental anomalies like molar gemination.
- Successful surgical intervention resolved the patient's symptoms and prevented further complications.
- Understanding such anomalies aids in accurate diagnosis and effective treatment planning in dentistry.
