One of the major factors in a successful root canal therapy is the knowledge of anatomy and root canal morphology. The presence of4-rooted maxillary second molars has been described in only a limited number of case reports. The purpose of this report was to show presence of two palatal roots in maxillary second molar in one patient. A 43-year-old female patient was referred for root canal therapy of maxillary right second molar due to invasive caries. The diagnostic radiograph revealed presence of anomaly in roots. After access cavity preparation presence of four orifices in pulp chamber was confirmed and all of the steps of root canal therapy was performed. Knowledge of the most common anatomic characteristics and their possible variations of root canal morphology is fundamental. Report of uncommon cases can motivate the dentist to consider the rarities during root canal therapy
