Perforation Repair of a Primary Tooth: A 1-Year Follow-Up Case Report

Aim and Background Primary teeth are more susceptible to perforation during endodontic treatment due to their anatomical features. Perforations, unintended communications between the root canal and external root surface, are a common procedural accident in endodontics, often leading to tooth loss. Managing these perforations in primary teeth is challenging, with prognosis dependent on factors such as location, size, and contamination. Traditional sealing materials have limitations like microleakage and toxicity. Mineral trioxide aggregate (MTA) is superior due to its sealing ability, biocompatibility, and promotion of hard tissue formation. Case Presentation This case report describes a furcal perforation repair in a primary molar using MTA in a 5-year-old child. Repulpectomy with calcium hydroxide based obturating material was performed. Follow up was done at 3, 6 months and 1 year. Conclusion With availability of bioactive materials like MTA, perforations in primary teeth can be repaired with good clinical and radiographic success. Clinical significance As stated the best space maintainer is the primary tooth by itself. Therefore, perforation repair with MTA can be a viable alternative to extraction in young children thus the tooth can be preserved and meet the functional demands.
