Definition.
The bulk of tooth structure on the occlusal surface at the point of contact of posterior teeth is referred to as the marginal ridge..
Marginal ridge - A linear, rounded border of enamel that forms the mesial and distal margins of anterior teeth as viewed from the lingual, and the mesial and distal borders of occlusal surfaces on posterior teeth..
Marginal ridges are the rounded borders of the enamel that form and limit the margins of the occlusal surface.
Each premolar and molar has a mesial and distal ridge on the occlusal surface..
Food impaction often can be prevented by establishing consistent marginal ridges on adjoining teeth and accentuating food escape grooves.
Burch4 stated that all adjacent marginal ridges should be at the same height to prevent food lodgment and reten tion..
Ridges are any linear elevation on the surface of the tooth and receive the name after the position on the surface
Marginal ridges are the rounded borders of the enamel that form and limit the margins of the occlusal surface
Each premolar and molar has a mesial and distal ridge on the occlusal surface
On 233 mandibular second molars, marginal ridge grooves were found on 57% on the mesial and 35% of the distal marginal ridges
On 209 mandibular first molars, marginal ridge grooves were found on 68% on the mesial and 35% of the distal marginal ridges
Both the distal contact area and marginal ridge are located at a slightly more cervical level than on the distal of the first premolar
The distal root depression is deeper than the mesial depression on the maxillary second premolar
