T/F
dental rads only need done before extractions
false - do before and after to be sure
caused by failure of the primary tooth’s roots to undergo absorption
retained deciduous tooth
- toy breeds
- canine and incisors most common
where does the adult maxillary canine erupt compared to the deciduous canine?
and the mandibular canine?
rostral
lingual
T/F
two versions of the same tooth should never try to occupy the same space at the same time
TRUE
aside from canines, permanent teeth erupt ___ to deciduous teeth
lingual and palatal
most common breeds who experience crowding
brachycephalics
most common tooth in crowding
maxillary 3rd premolar
supernumerary teeth (polodontia) is most common with what teeth
premolars (PM3)
*tooth has extra cusp
extra root of normal size
joining of two teeth
fusion
one crown with two roots with one or two root canals
fusion
less than normal amount of teeth in arcade
incomplete splitting into two teeth
gemination
missing teeth
anodontia. oligodontia, hypodontia
the shelf on the palatal surface of the maxillary incisors where the mandibular incisors occlude or rest
cingulum
example of class one malocclusion
base narrow canine
what class is parrot mouth/over shot
class 2 - mandibular distocclusion
mandibular brachygnathism is an example of what malocclusion class
class 2- mandibular distocclusions
mandibular prognathism
class 3 mandibular mesiocclusion
undershot is what class malocclusion
class 3 mandibular malocclusion
what is class 4 malocclusion
wry bite – asymmetrical skeletal malocclusion
most common class 2 malocclusion in dogs
base narrow canines
most common dog breed for lance tooth
shelties
rostrally displaced canine tooth - deciduous tooth in normal location
lance tooth – extract
one or more of the maxiallary insicors are displaced toward the palate
rostral cross bite - class 1 malocclusion
maxillary premolars are lingual to mandibular premolars or molars
caudal cross bite - not common class 1
considered a type of prognathism when the incisor crowns meet
level bite
removal of primary teeth to avoid or correct problem
interceptive orthodontics
fluid filled cyst surrounding the crown of an unerupted tooth resulting from persistence of portions of the enamel forming epithelium
dentigerous cyst
may see swelling/blue hue
missing teeth and pain
some causes of enamel hypoplasia
high fevers
distemper
periapical inflammation
endocrine dysfunction early in life
pathological wearing due to contact with opposing tooth
attrition
caused by abnormal contact with crown surface by foreign object

post op care from gingival hyperplasia resection
twice daily for two weeks chlorhex .12% conc rinse
pulpitis

vital pulpotomy / root canal / extraction
T/F
endodontics is less invasive than extractions
true
what is the objective of vital pulpotomy
maintain a viable tooth that will continue to mature
____ is necessary to maintain dentin
the pulp
otherwise the tooth will become dehydrated and brittle
age range for vital pulpotomy
young <18 - 24 months
success lowers with age because pulp gets less resilient

sooner = better
<48 hours has 80% success
monitor at least yearly
