What may result from Vitamin A deficiency during tooth development?

Tooth discoloration
Dentinogenesis imperfecta
Enamel hypoplasia
Root resorption

The correct answer is: Enamel hypoplasia

During tooth development, Vitamin A deficiency can lead to Enamel hypoplasia. This condition results from a lack of enamel being formed on the tooth, which can lead to pits, grooves, or thin areas on the surface of the tooth. This is different from tooth discoloration, which is a change in color of the tooth, and dentinogenesis imperfecta, which is a genetic condition affecting the formation of dentin in the tooth. Root resorption is a condition that occurs when the roots of the tooth start to break down or dissolve, and it is not directly related to Vitamin A deficiency during tooth development. Therefore, Enamel hypoplasia is the most accurate and specific answer among the options provided.
