2 Flashcards
morphologically identical to permanent maxillary 1st molar including cusp of Carabelli;
primary max 2nd molar
smaller and squatter than permanent maxillary 1st molar
primary maxillary 2nd molar
roots of primary max 2nd molar
more flared and slender
small rot trunk
prrimary max 2nd molar
primary max 2nd molar
greatest faciolingual diameter of all primary teeth
tf primary max 2nd molar is smaller than primary 1st molar
f
larger than primary 1st molar
primary mandib 2nd molar
identical to permanent mandibular 1st molar
primary mandib 2nd molar
smaller and squatter than permanent mandibular 1st molar
cervical bulges and constriction
primary mand 2nd molar
more flared and slender than permanent 1st molar
roots of primary mandib 2nd molar
how many roots for primary mandib 2nd molars
2
M and D
small root trunk
primary mandib 2nd molar
have more pronounced cervical ridges (
primary teeth or permanent
primary teeth
more constricted at the cervix (neck)
primary or permanent
primary teeth
tf crown roots are long and narrow in relation to crown width and length
T
most unique primary tooth morphologically
primary mandibular first molar
Primary teeth are smaller in overall dimensions
to permanent teeth
large pulps with long pulp horns
primary teeth
more flared and slender roots which extend beyond the crown outlines, thus allowing space for the growth and development of the succeeding permanent teeth
primary molar
primary molars
short root trunks
and furcation areas approaching the CEJ
tf Primary pre-molars have buccal and lingual surfaces that are more convergent occlusally, result in narrow occlusal table
f
Primary molars have buccal and lingual surfaces that are more convergent occlusally
correct the statement
primary teeth; thin enamel with dispersed thickness
primary teeth; thin enamel with consistent thickness
difference between primary molar and permanent molars
enamel rods of primary molars at the CEJ point occlusally rather than gingivally as with permanent molars
tf
Primary teeth have lot of dentin between pulp and dentino-enamel junction (DEJ)
F
Primary teeth have little dentin between pulp and dentino-enamel junction (DEJ)
comparatively longer and narrower roots with respect to their crowns
primary ant teeth
primary ant teeth vs permanent ant teeth
primary ant teeth
appear wider mesiodistally and shorter occlusocervically
more flared and slender roots which extend beyond the crown outlines, thus allowing space for the growth and development of the succeeding permanent teeth
primary molar
primary molars

primary ant teeth
primary ant teeth vs permanent ant teeth
primary ant teeth
appear wider mesiodistally and shorter occlusocervically
lack mammelons on incisal ridge
primary ant teeth
tf The teeth of children and young people are more sensitive than the teeth of older people to thermal change and dental operative procedures
t
leeway space
Primary molars are wider mesiodistally than the premolars that replace them
leeway space
allows space for some mesial movement of the permanent first molars as the premolars erupt
