What is the name of the condition characterized by improperly formed enamel?

1. Amelogenesis imperfecta

2. Enamel hypoplasia

3. Dental caries

4. Fluorosis

The correct answer is: Amelogenesis imperfecta

Amelogenesis imperfecta is a genetic condition that affects the formation of enamel, leading to enamel that is poorly formed and may exhibit various abnormalities in color, thickness, and texture. This condition is a result of a disruption in the process of amelogenesis, which is the development of enamel during tooth formation. Individuals with amelogenesis imperfecta may have teeth that are more susceptible to wear, sensitivity, and increased risk of dental caries due to the compromised enamel structure. On the other hand, enamel hypoplasia refers to a defect characterized by the underdevelopment or incomplete formation of enamel, which might result from systemic conditions during tooth development but is distinct from the genetic nature of amelogenesis imperfecta. Dental caries is a result of decay caused by bacteria and does not pertain directly to the formation of enamel itself. Fluorosis is a condition caused by excessive fluoride exposure during tooth development, which can lead to mottling or discoloration of the enamel but not necessarily to improper formation of the enamel structure as seen in amelogenesis imperfecta.
