345 - Delayed Replantation of Avulsed Tooth in 9-year-old with Rett Syndrome: A Case Report

Oral manifestations of Retts syndrome include bruxism, mouth breathing, tongue thrusting, and anterior open bite. These presentations create a less favorable oral environment for successful replantation of avulsed teeth. We report a case of delayed replantation in a 9-year-old female with Retts syndrome. She presented to the emergency department approximately one hour after avulsion with the tooth in a paper towel. She subsequently transferred to the dental clinic 2 hours later with the tooth in milk. Extraoral RCT was performed, and the tooth was replanted followed by a flexible splint. There was a total of over 4 hours extra-oral dry time. Patient has been followed for 3.5 years with no signs of clinical or radiographic pathology, pain, swelling or infection. This case illustrates successful replantation of an avulsed tooth in a pediatric patient with Rett’s syndrome despite an unfavorable oral environment.
