Anatomy Flashcards
Linear elevation of enamel found at the mesial and distal borders of the occlusal surface of posterior teeth
Marginal Ridges
Ridges which descend from the tips of cusps of posterior teeth toward the central area of the occlusal surface
Triangular Ridges
The combination of 2 triangular ridges, which transversely cross the occlusal surface on a posterior tooth to merge with each other.
Transverse Ridge
The ridge that is found only on maxillary molars.
Oblique Ridge
It crosses the occlusal surface of maxillary molars in an oblique direction from the triangular ridge of distobuccal cusp to a ridge of mesiolingual cusp.
Oblique Ridge
Form the shape of a four-sided somewhat rounded pyramid.
Cusp Ridges
The mesial and distal cusp ridges are also known as
Cusp Slopes
Found on molars and premolars on the occlusal surfaces of mesial or distal to marginal ridges
Triangular Fossae
Major, sharply defined narrow, linear depressions formed during tooth development and usually separating the lobes or major portions of a tooth
Developmental Groove
This is less distinct, also a shallow linear depression on the surface of a tooth, but is supplemental to a developmental groove and does not mark the junction of primary parts
Supplemental Groove
This is located in the buccolingual center of the tooth and runs mesiodistally
Central Groove
A long depression or valley in the surface of a tooth between ridges and cusps, the inclines of which meet at an angle
Sulcus
A very narrow cleft or crevice at the depth of any groove, caused by the incomplete fusion of enamel during tooth development
Fissure
Small pinpoint depressions located at the junction of developmental grooves or at terminals of those grooves
Pits
A term used to describe a landmark in the central fossa of molars where developmental grooves join
Central Pit
