The root canal aberrations and variations in maxillary second permanent molars is a constant challenge and successful endodontic management with latest adjuncts decreases the failure of missing a canal. Detection of all the root canals and their disinfection is important for proper healing and long-term survival of the tooth. It is considered that fusion of the teeth can occur anywhere and that the location of fusion can be in any of the cervical, middle, or apical thirds or in some combination. This case report discusses and highlights the management of endodontically challenged upper molars.
