OBLIQUE RIDGE Meaning and
Definition
-
An oblique ridge refers to a prominent elevation or ridge that is slanted diagonally across the occlusal or incisal surface of a tooth. It is typically observed in molars and premolars, although it can also occur in other teeth. The oblique ridge is formed by the joining of two triangular ridges, which are raised elevations on the cusps of the tooth.
This ridge extends obliquely across the occlusal surface, from the mesiolingual area to the distobuccal area of the tooth. It acts as a barrier that separates the occlusal table into two unequal halves. The ridge is more pronounced in some teeth, particularly the maxillary molars, and plays a vital role in occlusion and mastication.
The oblique ridge is crucial in guiding the movement of the lower teeth during chewing and grinding. It ensures that the cusps of the opposing teeth fit and engage in a stable and functional occlusion. This ridge also helps in the distribution of occlusal forces during chewing, preventing excessive stress on certain areas of the tooth and promoting proper tooth wear.
Understanding the presence and significance of the oblique ridge is essential for dental professionals, as it influences various dental procedures, including restorative dentistry, prosthetics, and endodontics. Dentists and dental hygienists carefully examine this ridge to assess occlusal relationships and detect any abnormalities or wear patterns that may affect the overall function and health of the dentition.

Etymology of OBLIQUE RIDGE
The word "oblique" originated from the Middle French word "oblic" meaning "slanting" or "slanted", which further evolved from the Latin word "obliquus" with the same meaning. "Ridge", on the other hand, is derived from the Middle English word "rigge" or "rygge" meaning "the crest of a hill". When combined, "oblique ridge" refers to a slanted or diagonal crest or elevated structure. In dentistry, the term specifically refers to a raised area on the occlusal (biting) surface of a tooth.
