What are the three types of dens evaginatus?

The classification of dens evaginatus into three types is focused on the variations of the structures resembling a cusp that projects from the surface of a tooth. The correct answer identifies the classifications accurately.

Type I, known as a talon cusp, refers to a significant anomaly where an additional cusp-like structure extends from the facial surface of a primary or permanent tooth, resembling the talon of a bird. This can affect the function and aesthetic of the tooth but typically is asymptomatic.

Type II, the semi-talon cusp, is characterized by a less pronounced extension than the full talon cusp but still presents a small cusp-like elevation. This variation can arise when there is partial development of the talon cusp structure, indicating varying degrees of the condition.

Type III, termed trace talon, represents a minimal or subtle version of the talon cusp structure, often detectable only through imaging or close examination, making it the least prominent of the three classifications.

This classification scheme is crucial in understanding the morphological variations seen in dens evaginatus and aids dental professionals in diagnosis and treatment planning. The choices that include terms like hyperplastic, gemination, or hypocalcified incorrectly represent conditions that do not align with the categorization of dens evaginatus. The
