Modern Dental Assisting Tooth Morphology Flashcards
Bicanineate
two-cusp type of mandibular second premolar
Bifurcated
Divided into 2
Bifurcation
Area in which 2 roots divide
Canine eminence
external vertical bony ridge on the labial surface of the canines
Central groove
most prominent developmental groove on the posterior teeth
Cingulum
raised, rounded area on the cervical third of the lingual surface
Cusp
Major elevation on the masticatory surface of canines and posterior teeth
Cusp of Carabelli
Fifth supplemental cusp found lingual to the mesiolingual cusp
Diastema
Space between two teeth
Fossa
wide, shallow depression on the lingual surfaces of the anterior teeth
Furcation
Area between two or more root branches
Imbrication lines
slight ridges that run mesiodistally in the cervical third of the teeth
Mamelon
rounded enamel extensions on the incisal ridges of the incisors
Marginal Groove
A developmental groove that crosses a marginal ridge and serves as a spillway allowing food to escape during mastication
Marginal Ridge
Rounded raised border on the mesial and distal portions of lingual surfaces of the anterior teeth and the occlusal table of the posterior teeth
Molars
Teeth located in the posterior aspect of the upper and lower jaws
Morphology
study of form and shape, as of the teeth
Nonsuccedaneous
permanent teeth that do not replace a primary tooth
Pegged Laterals
incisors with a pointed or tapered shape
Succedaneous
permanent teeth that replace primary teeth
Triangular Groove
A developmental groove that separates a marginal ridge from a triangular ridge of a cusp
Tricanineate
a three-cusp type of mandibular second premolar
Trifurcated
divided into 3
Trifurcation
Area in which three roots divide
