Summary
Scanning electron microscopy revealed enamel pearls with irregular surfaces, some featuring cementum. These findings highlight unique enamel pearl microstructures and potential resorption and repair processes.
Area of Science:
- Dentistry
- Oral Biology
- Microscopy
Context:
- Enamel pearls are developmental anomalies.
- Their microscopic structure is not fully understood.
- Scanning electron microscopy (SEM) offers high-resolution imaging.
Purpose:
- To characterize the surface morphology of enamel pearls using SEM.
- To identify structural irregularities and potential pathological changes.
Summary:
- Five enamel pearls were analyzed via SEM.
- External surfaces varied, with some bare enamel and others cementum-covered.
- Observed features included irregular enamel, Tome's pits, enamel caps, focal holes, resorption lacunae, and repair areas.
Impact:
- Provides detailed insights into enamel pearl microstructure.
- Contributes to understanding developmental anomalies in dental enamel.
- Informs potential clinical considerations for enamel pearls.
