Objective: to show the characteristics of Turner´s hypoplasia and its potential causes through case reports, emphasizing the importance of early detection and differential diagnosis with other development defects of tooth enamel. Turner´s tooth is a local enamel hypoplasia, featured by a defect in quality and thickness of enamel. The most affected teeth are upper and lower premolars. The most likely etiology is from a periapical infection that was present in the primary tooth predecessor, affecting the development of the permanent tooth. The severity of hypoplasia may range from whitish or brownish stains to loss of tooth structure, which will influence proper clinical management, in addition to the degree of dentinal sensitivity, patient behavior, and caries risk. Case Reports: to present two case reports of pediatric patients with Turner's hypoplasia in premolars, with different degrees of severity and clinical procedures. Final considerations: the knowledge of the pathognomonic aspects of Turner´s hypoplasia is essential for correct diagnosis and determination of an appropriate treatment plan, aiming to preserve tooth structure, facilitate oral hygiene, and decrease tooth sensitivity.
