What defines dens evaginatus?

• A. Development of an extra tooth root
• B. Outfolding of tooth surface prior to calcification
• C. Fusion of two separate teeth
• D. Reduction in tooth size due to trauma

Answer: (B)

Dens evaginatus is defined as an outfolding of the tooth surface, typically occurring before the full calcification of the tooth occurs. This anomaly is most commonly observed in molars and can result in an accessory cusp appearing on the occlusal surface of the tooth. The outfolding involves the enamel and dentin and can lead to clinical complications, such as potential wear, fracture, or entrapment of food and plaque, which may predispose the area to caries or periodontal issues if not properly managed.

The developmental nature of dens evaginatus helps highlight its significance within pediatric dentistry, as it can affect the oral health and management strategies for young patients. Understanding this condition aids in formulating appropriate treatment plans and preventive care for children who present with this anomaly.
