primary teeth Flashcards
a consequence of premature primary tooth loos
adult tooth crowding
what teeth are in primary dentition
central/lateral incisors, canines,molars
adult teeth # __-__ replace primary teeth A-J and adult teeth # __ replaces primary teeth K-T
4-13 replace A-J
20-29 replace K-T
succedaneous teeth
incisors, canines, premolars
premolars replace which teeth
replace primary molars
non-succedaneous teeth
molars
primary teeth crowns form between - months in utero
4-6
all primary teeth are erupted by age
2-3
order of emergence of primary teeth
mandibular central incisor other incisors first molars canines second molars
order of emergence of secondary teeth
first molars and mandibular central incisors 6
other incisors 7-9
mandibular canines 9-10
premolars 10-12
maxillary canines 12
second molars 12
3rd molars 17-21
which are whiter? primary or secondary dentition
primary
anterior roots of primary bend __ in apical third
labially/facially
which are larger in primary dentition, 1st or 2nd molars
second molars are larger than firsts
all primary incisors are longer incisocerically than mesiodistally EXCEPT
maxillary central incisor
mesial contact of primary maxillary canine
more cervical than distal
primary anterior maxillary canine has which cusp ridge longer (distal or mesial)
mesial cusp ridge is longer than distal, similar to only other which is permanent maxillary 1st premolar
primary mandibular cingula may be offset slight to the
distal
all molars wider mesiodistally than __ that will replace them
premolars
all primary molar have prominent
prominent buccal bulges
primary second molars resemble secondary
secondary first molars
*permanent 1st molars erupt next to primary 2nd molars
primary second molars are __ than permanent first molars
smaller
2nd primary molar looks like permanent
1st molar
maxillary primary second molar mesiobuccal cusp is ___ cusp
almost equal to mesiolingual
*while ML cusp is largest on permanent first molars
mandibular second molar has 5 cusps, 3 buccal and two lingual, just like the secondary dentition, the __ cusp is widest in the primary second molar
distobuccal cusp is widest
MB and D cusps are almost the same size in primary dentition while the D cusp in permanent is
the smallest
lingual or buccal cusps slight shorter than the other
lingual cusps slightly shorter than buccal
what is unique in shape about the primary 1st molar
no resemblance to any other molar
primary maxillary 1st molar, 4 cusps: 2 prominent =
and two very small
mesiobuccal and mesiolingual large
distobuccal and distolingual cusps very small
