Which dental anomaly is characterized by abnormal dental enamel formation?

Amelogenesis imperfecta is a specific condition that affects the formation of dental enamel. This genetic disorder leads to the aberrant development and mineralization of the enamel, resulting in varied manifestations such as thin, discolored, or pitted enamel. The enamel may be soft and can wear down more easily compared to normal enamel.

This condition can occur in different forms, including hypoplastic (insufficient enamel formation) and hypomaturation or hypocalcified types (enamel that is poorly mineralized). These characteristics directly correlate with the abnormal enamel formation that defines amelogenesis imperfecta.

In contrast, hypocalcification is more about the inadequate mineralization of enamel but does not encompass the broader spectrum of enamel development issues seen in amelogenesis imperfecta. Dentinogenesis imperfecta primarily involves dentin rather than enamel and affects the underlying tooth structure. Gingival recession is related to gum tissue rather than the formation of any dental structure, focusing on the condition of the gums rather than the enamel itself.
