2 molars
1, Inferior alveolar artery; 2, dental arteriole; 3, pulpal branches;
4, periodontal ligament arteriole; 5 and 6, interalveolar arterioles.
hard and soft palate
The anteroposterior curved line that connects the cusp tips of the posterior teeth
curve of spee
The mediolateral curved line that connects the buccal and lingual cusp tips on each side of the arch (frontal view
curve of wilson
never flat
Allows maximum use of occlusal contacts
occlusal plane
crest or ridge that extends from the apex of a cusp of a premolar or molar tooth toward the central part of the occlusal surface
triangular ridge
cingulum
a U- or W-shaped ridge at the base of the lingual surface of the crown of the upper incisors and cuspidteeth,
a pointed end where two curves meet, in particular.
cusp
tubercle
. A small elevation of variable size on the crown of a tooth representing a thickened area of enamel or an accessory cusp.
ridge of teeth
any linear elevation on the surface of a tooth and is named according to its location
marginal ridge
transverse ridge
triangular ridge
oblique ridge
fossa
A rounded or angular depression in the occlusal surface of a posterior tooth bordered by the cusp ridges and the occlusal table.
sulcus tooth
The gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium.
he slight depression dividing the lobes on an anterior tooth, and running parallel with the long axis.
developmental grove
supplemental groove
minor, auxiliary groove that branches off from a much more prominent developmental groove.
divisions of tooth come together to form tooth
lobe
mesial, buccal (labial on canine), distal, and
cusp ridges

mesiolingual incisal and distal lingual incisal point angle
mesial lingual incisal point angle
and\distal lingual incisal point angle of ant teeth
perikymata (Greek plural of perikyma)
are the pits around the long prisms of tooth enamel. They indicate the places where enamel-producing cells used to make contact with neighboring cells and are the result of normal enamel apposition.
interdental pappilla
An extension of the gingiva that normally fills the triangular space (i.e. gingival embrasure) between two adjacent teeth in contact just below (cervical to) the proximal contact area
diastema
A space between two adjacent teeth (not contacting) in the same dental arch
incisal occlusal embrasure
buccal embrasure
lingual embrasure
ging or cervical embrasure embrasure
