Unique Presentation of “U Shaped” Impacted maxillary Central Incisor with Surgical and Pedodontic perspectives: A Case report

BackgroundDilaceration, a developmental disturbance, is thought to be due to trauma leading to change in the position of the calcified portion of the tooth and the tooth is formed at an angle. Such an injury to a permanent tooth, resulting in dilacerations, often follows traumatic injury to the primary predecessor. A study by Patiletal, on Indian population reported the prevalence of very rare developmental dental anomalies and dilaceration was found to be only about 0.5% in prevalence.Case detailsA 9 year old male reported to the department of paediatric dentistry with complaint of missing central incisor in maxillary left arch. Radiographic examination revealed impacted maxillary left incisor with very unique and unusual extreme curve in root of same tooth giving it a characteristic U morphology. As the patient reported in mixed dentition stage, both the surgical, prosthodontic and pedodontic perspectives were kept in mind before planning for the treatment. Surgical removal was planned as it was not possible to save and place the tooth in the arch. Although surgical removal was challenging due to extreme curve and highly placed position of tooth, surgical removal was done successfully with roots and crown broken in two sections in spite of proper care during extraction procedure. Edentulous space was replaced with groper’s appliance considering mixed dentition stage of the patient after successful healing as per the pedodontic perspectives.ConclusionU shaped presentation of single rooted tooth is a one of the rarest findings. In children with age of interception, treatment should be planned wisely taking into consideration surgical, prosthodontic and pedodontic perspectives together.Key WordsU shaped root, dilaceration, impacted tooth, surgical and pedodontic perspectives
