pediatric Flashcards
calcification dates of primary teeth
14,15,16,17,18 Weeks in utero
A, D, B, C, E
calcification dates of permanent teeth
First molars Birth
All anterior teeth except maxillary laterals 6 months
Maxillary laterals 12 month
First premolars 18 months
Second premolars 24 months
Second molars 30 months
multiple supernumerary teeth
cleidocranial dysplasia
congenital missing primary teeth
max LI
most ankylosed primary teeth
mand 1st molar
generalized microdontia
- Down syndrome, pituitary
dwarfism, ectodermal dysplasia
Localized microdontia
peg-shaped maxillary lateral
Generalized macrodontia
Pituitary gigantism or pineal
hyperplasia with hyperinsulinism
Localized macrodontia
Hemifacial hyperplasia
dens evaginatus
extracusp
dens in dente
dens invaginatus
dens in dente is seen in
per max LI
taurodontism is seen in which
4 amelogenesis imperfecta
blue sclera is seen in
dentinogenesis imperfecta
ghost teeth
regional odontodysplasia
concrescence is m.c seen in which teeth
per max molars
primary teeth features
- Thinner enamel
- Bigger pulp
- Whiter
- Occlusally directed
enamel rods - Cervical bulge
- More divergent roots
- Small or absent root
trunk
1* max CI
widest anterior MD
1* max canine
widest anterior FL
MCR > DCR just like
maxillary 1st premolar
* Cusp tip offset distal
* Longer and sharper cusp
than mandibular canine
(and even permanent
maxillary canine)
prominent MF cervical bulge is
max 1* molar
crown resembles max perm 1st molar
max 1*2nd molar
widest FL
max 2nd molar
CUSP OF CARABELLI,DL GROOVE, OBLIQUE RIDGE
max 2nd molarprimary
- Most Unique teeth
highest and sharpest, largest cusps
- ML “ice cream cone” cusp
- MB cusp
1* 1st mand molar
*Most distinct MF cervical
ridge and transverse ridge
* Most difficult primary
tooth to restore
1st mand molar
Widest MD * Crown resembles a
permanent mandibular 1st molar except that
MB, DB, and D cusps are
nearly equal in size
2nd mand molar primary
For primary incisors with proximal caries that approximate or involves incisal edge
strip crown
contraindicated of pulpectomy
primary first molars because they usually have lots of accessory canals
indication of extraction
Necrotic first primary molar, nonrestorable, or with root resorption
extraction exception
a second primary molar with mild to moderate root resorption in a young patient which could be saved by endo therapy as a space maintainer
Primary first molar with furcation
involvement
EXT
Primary second molar with furcation
involvement
PE
diagnosis of ankylosed teeth
Out of occlusion since other teeth continue normal eruption
– No mobility
– Hollow sound when tapped
– Radiographic loss of PDL space
eruption cyst is common in
incisor and mand molars
aversive conditioning is avoided in
timid,tense cooperative
HOME is used for
Uncontrolled
atomoxetine is used for
ADHD
Autism
– Repetitive behavior
– The heightened sense of light and sound
- Intervention with appliance therapy recommended for thumbsucking is
age 5 or 6
to complete primary
tooth crown how many years does it take
Takes 2 years
to complete permanent
tooth crown how many years does it take
- Takes 4-5 years
