Summary
A partially erupted maxillary second premolar resisted orthodontic extrusion and required a composite onlay. Despite restoration, the tooth developed external root resorption, indicating a complex treatment outcome.
Area of Science:
- Dentistry
- Endodontics
- Restorative Dentistry
Background:
- Partially erupted teeth present diagnostic and treatment challenges.
- Orthodontic extrusion is a common approach for managing impacted or unerethrupted teeth.
- Restorative interventions are often necessary for teeth with compromised coronal structure.
Observation:
- A maxillary second premolar was partially erupted and unresponsive to orthodontic extrusion.
- An adhesive composite onlay was used to restore the tooth's crown.
- The patient later experienced pain, and radiographic examination revealed root resorption.
Findings:
- The extracted tooth exhibited vital pulp but extensive external root resorption.
- Evidence of repair with bone-like material was observed on the resorbed root surface.
- The tooth's resistance to orthodontic extrusion may have been linked to underlying pathology.
Implications:
- This case highlights the potential complications of restorative and orthodontic treatments in complex dental cases.
- External root resorption can occur even after successful coronal restoration.
- Further research is needed to understand the etiology and management of such resorption patterns.
