A Case study of a Rare Case of Turner's Hypoplasia and Unilaterally Fused Deciduous and Permanent Lateral Incisor Caused By Trauma

Orofacial trauma is a serious orodental and general health problem that may have medical, esthetic and psychological consequences for children and their parents. When the root of the primary tooth is close to the unerupted permanent tooth, primary tooth trauma may result in developmental disturbances and pulpal reaction in that permanent tooth. We report an unusual case of an 8 year old girl who met with trauma at 15 months of age in which injury to the primary dentition resulted in developmental disturbances in the crown of the permanent tooth and fusion between permanent and deciduous tooth. Localized malformation of the crown and enamel hypoplasia was treated with a light-cured composite resin restoration. The treatment of fused permanent and deciduous incisor is also discussed.
