What term describes separate parts that come together to form a tooth?

The term that describes separate parts that come together to form a tooth is "lobes." During tooth development, teeth form from multiple lobes that eventually fuse together. Each lobe contributes to the overall structure and shape of the tooth, and this is particularly evident in the anatomy of molars and incisors, which may contain several lobes. The fusion of these lobes plays a significant role in determining the tooth's final appearance and functionality, including the cusps that are essential for biting and chewing.

While mamelons, ridges, and pits are also features observed on teeth, they do not refer to the individual developmental parts that combine to create the tooth itself. Mamelons are the small, rounded projections on the incisal edges of newly erupted incisors, ridges refer to the raised lines on the surface of teeth, and pits are small depressions found on the tooth surface. None of these terms capture the concept of distinct segments coming together during the embryonic phase of tooth formation as well as "lobes" does.
