Management Strategies in Patient with Turner’s Hypoplasia: A Rare Case Report

The development of the crown of permanent teeth begins around six months of age, with crown completion by the age of 4-5 years, and root completion by 10 years. During this period, trauma to the primary dentition can disrupt ameloblastic activity, resulting in developmental defects in the permanent successor. The extent of the defect depends on the stage of enamel formation at the time of injury. Turner’s tooth is a localised form of enamel hypoplasia commonly associated with trauma or infection of a primary predecessor. Clinically, it may present as well-defined white, yellow, or brown discolouration or varying degrees of enamel hypoplasia, sometimes involving the entire crown and compromising aesthetics and function. Herein, the authors present a case report of a 12- year-old male patient. with a history of early childhood trauma who presented with Turner’s hypoplasia affecting the maxillary anterior teeth. Clinical and radiographic evaluation revealed structural enamel defects with associated pulpal involvement in one tooth. The treatment plan included root canal therapy, apexification where indicated, reinforcement with fiber post and core and restoration with a Polymethylmethacrylate (PMMA) crown. Multidisciplinary approach, such as root canal treatment on vital teeth, crown lengthening, fibre posts and PMMA crowns, was adopted to restore aesthetics and function while preserving maximum tooth structure. The patient was reviewed clinically and radiographically regularly to assess healing and clinical progress, which was favourable.
