A linear elevation of enamel found on the occlusal surface of posterior teeth and the lingual surface of anterior teeth along the mesial and distal borders. These structures form the mesial and distal boundaries of the occlusal surface of premolars and molars, and contribute to the lingual fossa’s margins in anterior teeth. Their presence aids in containing food during mastication and contribute to the overall structural integrity of the tooth.
The presence of these enamel borders is critical for maintaining proper food flow and preventing food impaction between teeth, thereby reducing the risk of periodontal disease. Their developmental characteristics are crucial in understanding tooth morphology and function. Historically, the study of these ridges has been essential for dental professionals in restorative dentistry and occlusion analysis.
