A ridge is an elevated portion of a tooth that runs in a line and is named for the specific location in which it occurs.Specifically,marginal ridges are the rounded borders of enamel that form the mesial and distal elevated shoulders of the occlusal surfaces of posterior teeth as well as the mesial and distal shoulders of the lingual surfaces of anterior teeth.
Fossae,grooves,and pits are depressed formations within the tooth.They are also described as concavities,indented areas,or simply concave structures.A fossa is broadly defined as a depression or concavity.Developmental grooves are shallow,depressed lines that separate primary parts of the crown or root.A pit is a pinhole evident within a fossa or anywhere on a tooth.A lingual pit occurs on the lingual surface of a tooth.
