Definition: Physiologic wearing of teeth due to tooth-to-tooth contact, often associated with bruxism (teeth grinding).
Radiographic Features:
- Location: Incisal and occlusal surfaces
- Edge: Well-defined
- Shape:
- Flat occlusal plane
- Reduced crown height
- Internal:
- Radiolucent areas on incisal/occlusal surfaces
- Loss of enamel radiopacity in affected areas
- Number:
- Often affects all anterior teeth
- Can involve all teeth in severe cases
Key Diagnostic Signs:
- Generalized flattening of occlusal/incisal surfaces
- Uniform reduction in crown height
Clinical Significance:
- Can lead to decreased vertical dimension of occlusion
- May cause temporomandibular joint problems
- Potential for tooth sensitivity due to enamel loss
- Severe cases may require full mouth rehabilitation
- Often indicates need for night guard to prevent further damage
Note: While radiographs can show evidence of attrition, clinical examination is crucial for full assessment. Differentiation from abrasion and erosion is important for proper management. Identifying and addressing the underlying cause (e.g., stress, malocclusion) is essential for long-term treatment success.
