Maxillary Central & Lateral Incisors
Pulp cavity (chamber & canal) *Follows the configuration of the crown *the same as the central’s. but in some
& the root* specimens the incisal end of the
•mesiodistal section: chamber is rounded rather than the
-Wide pulp chamber presenting 3 pulp three pulp horns
horns.
-The chamber is wide till the cervical line
where it tapers towards the apical
foramen forming the root canal
•labiolingual section:
-pointed towards the incisal edge then
widens till the cervical line then tapers…
forming the root canal
•cross section at the cervix:
-circular & centered in the root
-or triangular because of the lingual
convergence (in the young)
features -Mesiolabial & distolabial shallow DGs -also has ML & DL DGs
-less prominent elevations & depressions -more prominent …
-larger shallow lingual fossa -smaller but deeper lingual fossa
-lingual pit is less common -lingual pit is more common
-deep developmental groove near the
cingulum on the lingual fossa
-another DG distal to the cingulum
which may extend on most of the
root’s length (not common)
-tubercle may exist as a part of the
cingulum
-a lot other variations may occur as
twisted roots or may be missing
