Dens evaginatus typically results in what anatomical change?

• A. Formation of an extra tooth root
• B. Formation of an extra bump or cusp
• C. Displacement of the tooth in the gum
• D. Loss of tooth structure

Answer: (B)

Dens evaginatus is a developmental anomaly characterized by the presence of an additional cusp on the occlusal surface of a tooth, most commonly observed in the premolars. This extra bump or cusp, often referred to as an "accessory cusp," results from an abnormality during the development of the tooth in the dental arch. The formation of this extra structure can lead to unique occlusal patterns and may have implications for dental treatment, as these accessory cusps can be prone to wear, fracture, or caries if not properly managed. Understanding dens evaginatus and its presentation is crucial for proper diagnosis and treatment planning in dentistry. In the context of the other choices, the process does not involve the formation of an extra tooth root, a displacement of the tooth in the gum, or a loss of tooth structure, which are characteristics associated with different dental conditions.
