Abstract:

Maxillary first molar teeth usually have 4 cusps, a few teeth have stuck cusps on the lingual side of the mesial tongue tip, while the presence of additional cusp on the buccal side of the mesial buccal tip is rarely reported, and it is even more rare for the cusp to connect with the dentin, cementum and pulp cavity of the main crown and fuse together to form C-shaped roots. A case of the buccal supernumerary cusp of the right maxillary first molar with C-shaped root canal was reported.

Key words: Supernumerary cusp, C-shaped root, Root canal therapy
