Etiology: Teeth
Any tooth surface can develop a cavity.
Some surfaces are more prone, including newly erupted teeth due to immature enamel and teeth with developmental defects.
Nature of Enamel Defects
The cells that manufacture enamel are very sensitive to systemic insults. Disruption in the enamel production during tooth development will result in a defect which may be microscopic or macroscopic.
- 20-40% percent of children have developmental defects of enamel.
- Defects may appear as changes in translucency, color, or texture.
- It may be difficult to distinguish enamel defects from early clinical signs of caries though this does not affect management.
- Enamel defects are associated with substantially increased risk of ECC.
- Enamel defects occur more often in children who have:
- Lower socioeconomic status (SES)
- Premature birth
- Certain congenital, genetic diseases, or special needs, such as cerebral palsy and intellectual disabilities
