On which tooth is the cusp of Carabelli usually found?

The cusp of Carabelli is typically found on the upper molars, specifically on the mesiolingual cusp of the maxillary first molar. This accessory cusp can vary in size and presence, but it is most commonly associated with maxillary molars.

In dental anatomy, the maxillary first molar is characterized by having multiple cusps, and the cusp of Carabelli is considered an anatomical variation that few individuals may possess. It is not found on lower incisors, and while lower molars and upper incisors may have various anatomical features, the presence of this specific accessory cusp is primarily a trait associated with the upper molars. This is why selecting the upper molars as the answer is accurate and reflects an important aspect of dental anatomy and variations.
