Endodontic management of maxillary second molar with fused paramolar tubercle and two palatal roots: An unusual case report

Morphological variations are frequently observed in the crown as well as in the roots of maxillary molars. One such diversity is the prescence of a supernumerary cusp termed as paramolar tubercle. The clinician must have a thorough knowledge of the external as well as internal tooth morphology and novel diagnostic aids like cone-beam computed tomography aids in the successful management of these cases. This case report describes the successful diagnosis and treatment of a four-rooted maxillary second molar with paramolar tubercle and five root canals. The maxillary second molar tooth had two palatal roots with individual canals in addition to the extra canal of tubercle. This combination is very rare and first of its kind to be reported in the literature.
