A 7-year-old child presents with a yellowish discoloration on a maxillary central incisor. The mother reports a history of trauma to the primary tooth three years ago, accompanied by repeated infections and swelling. What is the most likely diagnosis?

Explanation

Turner's hypoplasia occurs as a result of trauma or infection affecting a primary tooth, which subsequently disrupts the development of the underlying permanent tooth, leading to localized enamel defects such as yellowish discoloration. Other conditions like generalized dental fluorosis, syphilitic hypoplasia, and rickets-related hypomineralisation usually present with different patterns or systemic involvement.
