Definition
maxillary central permanent
Term
True or false, permanent teeth are white in color than primary teeth
Definition
false.
Term
One of the reasons primary teeth get cavities faster is because they are less mineralized?
Definition
true
Term
explain the lenght of a tooth in relation to crown size
Definition
the root is longer in lenght compared to the crown. The crown is shorter in lenght compared to the root.
Term
Explain the CEJ anatomy of a primary tooth.
Definition
it is constricted where the crown meets the CEJ causing a bulbous appearance.
Term
Which layers are thin in the primary tooth compared to the permanent tooth?
Definition
dentin and enamel
Term
Which layers are thin in the primary tooth compared to the permanent tooth?
Definition
dentin and enamel
Term
What unique feature about the pulp cavity effects the caries rate in primary teeth?
Definition
large pulp and pulp cavities makes primary teeth more susceptible to caries.
Term
Which teeth are more consistent in shape, primary or permanent?
Definition
primary
Term
What makes the crown appear round and bulbous?

Term
name two prominent feature on anterior primary teeth
Definition
cerivle ridges, and cingulums.
Term
describe the root properties of anterior teeth
Definition
tipped labially (facially) and they have a long root in proportion to the crown.
Term
What is the significance of having a tipped root?
Definition
allows room for the permanent crown to start forming.
Term
explain crown width on posterior teeth.
Definition
wider mesiodistally and short cervicle occlusally
Term

Definition
false.
Term
molars have a narrow chewing space in which direction?

Term
molars have a narrow chewing space in which direction?
Definition
buccolingual
Term
describe the buccal cusps of the posterior primary teeth and the occlusal surface
Definition
short and sharp, occlusal surface is short and shallow with not a lot of pits and grooves.
Term
which direction do the enamel rods slope in primary teeth?
Definition
occlusally.
Term
what is the significance of the root furcation on primary teeth?
Definition
short and small root trunks that allow cavities to travel deeply at a quick rate.
Term
why are the roots spread apart on posterior primary teeth?
Definition
allows room for the permanent crown to form.
Term
describe posterior root
Definition
slim and slender.
Term
which molar has wider spread roots, the first or the second?
Definition
second molar.
Term
explain the significance of the high pulp horns in primary teeth?
Definition
caries get to the pulp faster, seen well on the molars.
Term

Definition
MESIAL is more square and the distal is more round.
Term
maxillary lateral incisor features on the mesial distal aspect are?
Definition
more pointed at the mesial, rounded on the distal, small tooth.
Term
on the canines for both the maxillary and the mandibular, explain the contact points
Definition
mesial contact on maxillary is more apical, on the mandibular it is more coronal
Term
explain the feature of the roots of the maxillary molars
Definition
max 1st molar: short mesiobuccal root
max 2nd molar: large lingual root
