Aim: To describe and discuss the management of root perforation in the cervical third of a high esthetic demand zone in the maxillary incisor teeth.
Background and objectives: Biodentine is a calcium silicate-based repair material that requires a short setting time. This material has the advantage of setting in a matter of minutes without causing long-term discoloration, and exhibits biocompatibility similar to mineral trioxide aggregate (MTA). Polytetrafluoroethylene (PTFE) is a fluorocarbon solid, nontoxic to humans, highly resistant to heat and chemicals, and is used in dentistry as a barrier in adhesive restorations. We describe and discuss the management of root perforation in the cervical third of a high esthetic demand zone in the maxillary incisor teeth using these materials.
Case description: The present manuscript describes a technique in three cases of root perforation treated in a single-session appointment with Biodentine in combination with PTFE, that is utilized as a barrier to prevent the calcium silicate-based repair material from penetrating the root canal until the material fully sets, then the endodontic retreatment can be completed.
Conclusion: The technique described using PTFE as a barrier was effective to prevent the calcium silicate-based repair material Biodentine from penetrating the root canal during endodontic retreatment.
Clinical significance: Root perforation can be treated in a single session using PTFE and calcium silicate-based.
