Which condition is characterized by a deficiency of enamel leading to increased tooth sensitivity?

• A. Dentinogenesis imperfecta
• B. Amelogenesis imperfecta
• C. Iron deficiency anemia
• D. Hypoplasia

Answer: (B)

Amelogenesis imperfecta is the condition characterized by a deficiency of enamel, which significantly disrupts the normal structure and development of the enamel layer on teeth. This genetic disorder results in the enamel being thin, poorly mineralized, or entirely absent, leading to various clinical presentations that include increased tooth sensitivity and a higher risk for dental caries and wear. Individuals with amelogenesis imperfecta often experience difficulty with tooth care due to this heightened sensitivity, which can be exacerbated by exposure to temperature changes or certain foods. The condition can also affect the aesthetics of teeth, as the enamel may appear discolored or pitted. In contrast, dentinogenesis imperfecta involves defects in dentin formation, leading to discolored or brittle teeth but not primarily affecting enamel. Iron deficiency anemia has no direct effect on enamel formation, focusing instead on systemic health. Hypoplasia refers to a condition where there is underdevelopment of tissue or an organ, which can include enamel hypoplasia, but the term is more general and does not specifically refer to the inherited enamel deficiency seen in amelogenesis imperfecta.
