The cusp of Carabelli is typically found on which type of teeth?

Maxillary 1st Molars
Mandibular 2nd Molars
Maxillary Canines
Mandibular 1st Molars

The correct answer is: Maxillary 1st Molars

The cusp of Carabelli is most commonly associated with maxillary first molars. This anatomical feature is an additional cusp that is located on the mesiolingual line angle of the maxillary first molar. It can vary in its presence, shape, and size, but when it does occur, it’s a distinguishing characteristic of this particular tooth. This cusp is considered a variation of dental anatomy, and its presence can be influenced by genetic and ethnic factors, often being more prevalent in certain populations. Maxillary first molars are key to understanding the complex nature of dental anatomy, and recognizing features like the cusp of Carabelli helps in diagnosing and providing appropriate dental care. The other options do not typically exhibit this cusp, making the identification of it on maxillary first molars a valuable and necessary knowledge for dental professionals.
