Aim and background : Aim of this case report is to illustrate endodontic management of a taurodontic tooth. Case description : This manuscript is a case report that describes the endodontic treatment of a permanent taurodontic molar in a systemically healthy patient. A 56 year old female patient presented with pain in the maxillary left first molar, which exhibited hypertaurodonti sm and had three root canals. After radiographic evaluation, a conservative access cavity preparation followed by chemo mechanical preparation was performed. Passive ultrasonic irrigation was performed as an auxiliary protocol to finish cleaning, and a the rmoplastic obturation technique was used. Endodontic treatment of a tooth with hypertaurodontism might be difficult when it has complicated internal anatomy and supplementary root canals. At the follow up visit, the patient was asymptomatic, and radiograph ic evaluation showed improvement in the periodontal status. Considering the complexities of the current case, the six month assessment revealed favorable results due to the use of magnification during endodontic procedures as well as diligent attention to tooth preparation, cleaning and shape, and obturation techniques. Conclusion: This case report demonstrates that with careful diagnosis, meticulous treatment planning, and the use of advanced endodontic techniques, successful outcomes can be achieved in managing taurodontic teeth. This case underscores the importance of tailored endodontic approaches and the need for ongoing research and education to enhance the management of dental anomalies like taurodontism.
