How Do You Spell MARGINAL RIDGE?

1. A marginal ridge refers to a narrow elevated area located on the outer surface of a tooth, particularly in the back teeth known as molars and premolars. It forms the borders of the occlusal or chewing surfaces, running in either mesial or distal direction. The marginal ridge functions as a protective ridge that assists in preventing food particles and other debris from entering the crevices between the teeth.

   Anatomically, the marginal ridge is located at the junction of the occlusal and the proximal surfaces of a tooth, serving as a division between these regions. It is composed of enamel, the hard outer layer of a tooth, and primarily contributes to the structural strength and stability of the tooth. The marginal ridge also aids in guiding the cusps or the raised points on a tooth's occlusal surface during the chewing process, promoting efficient and effective mastication.

   Furthermore, the preservation of a tooth's marginal ridge is crucial for maintaining proper oral health. If it becomes worn down or compromised due to factors like tooth decay, attrition, or dental trauma, it can lead to various problems. These include increased susceptibility to dental caries, compromised chewing function, altered occlusion, and a higher risk of periodontal diseases. Dentists often closely examine and evaluate the integrity of the marginal ridge during routine dental check-ups to detect any signs of damage or deterioration and recommend appropriate preventive or restorative measures to maintain oral well-being.

2. One of the ridges of enamel on the outer edges of the masticatory, or occlusal surface of a premolar or molar tooth.
