What is Turner's tooth associated with?

• A. Malnutrition during childhood
• B. Infection of a primary tooth
• C. Genetic predisposition
• D. Exposure to fluoride

Answer: (B)

Turner's tooth, also known as Turner’s hypoplasia, is associated with the infection of a primary tooth, typically when it becomes necrotic. This condition occurs when a systemic infection, such as from a decayed primary tooth, affects the developing permanent tooth underneath it. The enamel on the affected permanent tooth does not form properly, leading to signs of enamel hypoplasia, which may present as discoloration, pits, or grooves on the tooth surface.

In this context, the link to infection is crucial because it highlights the impact that dental health in childhood can have on the development of permanent teeth. This connection underscores the importance of managing dental health early in life to prevent complications that can arise from untreated infections in primary teeth.
