Turner’s tooth refers to enamel hypoplasia occurring in a single tooth, also known as Turner’s enamel hypoplasia.
1.Turner’s teeth are most commonly found in the permanent upper incisors or upper and lower premolars, and their clinical manifestations vary due to the varying degrees of enamel hypoplasia. In mild cases, only the enamel is brownish-yellow, and in severe cases, there can be serious depression of the enamel and irregular crown formation.
2. The etiology of Turner’s tooth is mostly due to the occurrence of caries and apical tissue infection during the formation of the crown of the permanent tooth succeeded by the milk tooth underneath, or the trauma of the milk tooth embedded in the alveolar bone and affecting the permanent tooth embryo, which makes the enamel cell layer of the crown of the permanent tooth disturbed, resulting in the incomplete development of enamel of the permanent tooth, and the occurrence of Turner’s tooth.
When trauma or caries occurs in the milk teeth, it is necessary to consult the doctor in time, complete the examination, and standardize the treatment under the guidance of professional dentists to avoid the occurrence of Turner’s teeth.
