Definition: Additional tooth or teeth beyond the normal dental complement.
Radiographic Features:
- Location: Can occur anywhere in maxilla or mandible
- Mesiodens: More common in maxilla (anterior region)
- Peridens: More common in mandible (premolar region)
- Distodens: Molar region
- Edge: Well-defined
- Shape: Tooth-like
- Internal structure: Mixed radiopaque/radiolucent
- Radiopaque: Enamel and dentin
- Radiolucent: Pulp chamber and root canal
- Number: Single or multiple
Key points:
- Classification based on location:
- Mesiodens (anterior)
- Peridens (premolar)
- Distodens (molar)
- May interfere with eruption of adjacent teeth
Clinical significance:
- Can cause malocclusion, crowding, or impaction of permanent teeth
- May require surgical removal or orthodontic intervention
- Early detection is crucial for proper treatment planning
Note: Thorough radiographic examination is essential for accurate diagnosis and localization of supernumerary teeth.
