Özet

Developmental disturbances of unerupted permanent tooth result from trauma to primary tooth as there is a close proximity between the root of the primary tooth and its permanent successor. The damage to the unerupted permanent tooth occurs by the transmission of traumatic forces to the permanent tooth germ. In the present case, however, a developmental disturbance on the permanent maxillary central incisor resulting from a direct effect of the inversely intruded primary maxillary central incisor is presented. The intruded tooth was extracted under general anesthesia. Upon eruption of the permanent central incisor, a localized crown malformation along with enamel hypoplasia which was not classified as a developmental disturbance before was observed. The damaged sites were restored with a light-cured composite resin.
