Summary
Long-term pulpectomy in primary teeth using zinc oxide-eugenol (ZOE) paste can lead to retained filling particles. These particles may migrate during permanent tooth eruption, necessitating surgical removal for aesthetic reasons.
Area of Science:
- Pediatric Dentistry
- Endodontics
- Oral Surgery
Background:
- Pulpectomy is a root canal treatment for primary teeth.
- Zinc oxide-eugenol (ZOE) paste is commonly used as a root canal filling material.
- Long-term outcomes of ZOE in primary teeth require further investigation.
Observation:
- A case report details a child who underwent pulpectomy with ZOE paste in primary teeth.
- After 28 months, ZOE particles persisted and migrated from the gingival mucosa to the alveolar bone.
- The migration coincided with the eruption of permanent dentition.
Findings:
- Retained ZOE filling particles were observed in the periapical area long after root resorption.
- Periodontal surgery was required for aesthetic reasons due to particle migration.
- The long-term consequences of retained ZOE particles during permanent dentition eruption remain unknown.
Implications:
- Careful clinical and radiographic evaluation is crucial for primary teeth treated with pulpectomy and ZOE.
- Monitoring for radicular and ZOE filling paste resorption is essential.
- Further research is needed to understand the effects of retained ZOE particles on permanent tooth development and eruption.
