Answer;
Cingulum
Developmental lobes or bumps on the incisal edge of new maxillary anteriors are called Cingulum.
Step-by-step explanation;
-Cingulum is a collection of white matter, fibers projecting from the cingulate gyrus to the entorhinal cortex in the brain, allowing for communication between components of the limbic system.
-It forms connections between the frontal lobe, parietal lobe and temporal lobe. In non-human primates,it is divided into distinct subcomponents on the basis of corticocortical connections.
