MTA apexification of avulsed tooth with severe root resorption
14 year-old girl presented with a swelling on her lip due to an abscess from the tooth #9. She reported that the tooth fell out from the socket and was put back by her pediatric dentist —2 years ago. Root canal treatment was initiated to drain the abscess and the patient was referred to us for treatment.
The tooth #9 had a very short root most likely due to incomplete root formation and external apical root
resorption. The tooth was very loose with 2nd degree mobility and the prognosis was guarded. However the patient was too young to obtain an implant. We decided to attempt root canal treatment using apexification approach to maintain the tooth at least as a space maintainer until she can obtain an implant. Ca(OH)2 was placed inside the root canal until the tooth was stable with normal mobility. Root canal treatment was completed with MTA as an apical barrier and a root canal filling. The root canal access cavity was restored with composite resin. At 1 year- and 2 year-recall, the tooth appeared very stable and asymptomatic with complete PA bone healing.
