How is a ridge defined in dental terminology?

In dental terminology, a ridge is defined as a linear elevation of enamel. This means that a ridge is a raised, elongated area on the surface of a tooth, typically found on the occlusal (biting) surface of posterior teeth or along the cusps. Ridges play an important role in the function of teeth, as they contribute to the anatomy necessary for effective chewing and grinding of food.

The definition highlights the prominence of ridges in contributing to the overall form and function of the teeth. Understanding the prominence and placement of ridges can help dental professionals when analyzing tooth wear, fractures, or decay, and when preparing for restorative procedures.
