Which tooth is identified as having three roots and five cusps?

• A. Lower first molar
• B. Lower second molar
• C. Upper first molar
• D. Upper second molar

Answer: (C)

The tooth identified as having three roots and five cusps is the upper first molar. This tooth's anatomical structure is key to its classification. The upper first molar typically has three major roots: the mesiobuccal, distobuccal, and palatal roots. It also features five well-defined cusps: two on the buccal aspect (mesiobuccal and distobuccal), two on the lingual aspect (mesiolingual and distolingual), and one on the cusp of Carabelli, which is an additional cusp that may vary in presence among individuals. Understanding the morphology of the upper first molar is crucial in dental practice, as it plays a significant role in the occlusal function as well as in the process of mastication. Moreover, the identification of this tooth with its characteristic roots and cusps can assist dental professionals in performing procedures such as root canal therapy, extractions, and restorations correctly.
