This case report presents the protocol and outcomes of non-surgical retreatment performed on bilateral maxillary second molars (teeth #17 and #27) exhibiting an atypical two-canal anatomy. A 32-year-old systemically healthy male patient, who had undergone root canal treatment on both maxillary second molars approximately four years earlier, presented with pain and a sinus tract. The retreatment procedures were planned one month apart. Radiographic examination revealed a two- canal configuration in both molars, deviating from the commonly observed three-canal variant. Gutta- percha was removed using the ProTaper Universal Retreatment system (D1–D3), and the remaining filling materials were eliminated with ultrasonic tips. Calcium hydroxide was applied as intracanal medication between appointments. In the second session, sodium hypochlorite irrigation was ultrasonically activated, followed by final rinsing with saline and EDTA. Due to the irregular and wide canal morphology, mineral trioxide aggregate (MTA) was chosen as the obturation material. Within approximately two months following treatment, the patient reported complete resolution of symptoms first in tooth #17 and subsequently in tooth #27, with closure of the buccal sinus tract. Radiographic evaluation revealed periapical healing. This case highlights the importance of detailed anatomical assessment, ultrasonic activation, and bioceramic obturation materials in achieving successful endodontic outcomes. It also emphasizes that healing in bilateral cases may progress asynchronously, underscoring the need for close clinical follow-up.
