Definition: A small, round deposit of enamel found on tooth roots, primarily on molars.
Radiographic Features:
- Location: Most commonly on maxillary molars
- Edge: Well-defined
- Shape: Round
- Internal structure: Radiopaque, similar to enamel density
- Number: May be single or multiple
Key points:
- Most frequently occurs on maxillary molars
- Can be mistaken for overlapping adjacent roots on single radiographs
- May contain a small amount of dentin and pulp tissue (rare)
Clinical significance:
- Potential site for plaque accumulation and periodontal disease
- May complicate periodontal treatment
- Generally does not require treatment unless causing periodontal issues
Note: Two radiographs at different horizontal angles are recommended to confirm the presence of an enamel pearl and differentiate it from overlapping root structures.
