Flashcards in Intro to common oro-dental conditions in Cats and Dogs Deck (22):
1

Lingually Displaced Mandibular Canine Teeth

unilateral or bilateral
often with with mandibular distclusion (short mandible)
can be painful
will result in extensive palatal defects if left untreated

2

mixed dentition - define

during teething - mix of deciduous + permanent

3

persistent deciduous tooth - define

temp tooth still there when permanent tooth has already erupted

4

persistent deciduous tooth - treatment

dental radiograph - if resorption present
extraction
long thin roots prone to fragmentation

5

supernumerary teeth

often incisor/premolar teeth
crowding can cause periodontal disease - extract more abnormally positioned teeth
some supernumeraries only a cosmetic issue

6

missing teeth causes

hypodontia - congenital absence
impacted or embedded tooth - no eruption
traumatic crown fracture below gingival margin
diagnose by radiograph

7

enamel hypoplasia

enamel develops prior to eruption - hypoplastic enamel
noxius event during tooth development + before eruption

8

abrasion

tooth surface wears against abrasive objects
can cause reparative dentin or pulp exposure if fast

9

attrition

tooth on tooth wear
can cause reparative dentin or pulp exposure if fast

10

fracture types

with pulp exposure
root
crown + root
chip - no pulp exposure
pulpal blush - near pulp-exposure, pink point showing through dentin

11

intrinsic staining

tooth discoloured from within - blunt trauma

12

pulp exposure - test with sharp explorer

has a hole which tip of explorer will sink

13

reparative dentin

hard continuous surface
sharp explorer shouldn't stick or sink into

14

commonly overlooked fracture

older slab fracture
often covered with calculus
calculus deposits quicker due to the rough surface
upper fourth premolar

15

draining sinus tract - location

muco-gingival junction
can be explored with blunt probe

16

can fractured teeth be left if no problem

nope
periapical pathology develops soon after trauma - abscess formation inevitable
pain can be v.severe

17

what happens inside fractured tooth?

pulp exposure - microbial invasion - pulpitis - pulp necrosis
periapical pathology - bacteria try get into jaw bone + produce toxins
interactions of bacteria with immune response - pathological changes in jaw bone

18

periapical radiolucency - appearance on radiograph

bulbous shape
loss of lamina dura

19

treatment for fracture on 1st presentation

analgesia
antibiotics

20

definitive treatment of fractured tooth

extraction
vital pulp treatment
root canal therapy

21

oral mass lesions

neoplasia
hyperplasia, cyst, hamartoma
need biopsy + imaging

22

impacted teeth

1st premolar most commonly affected
brachycephalics predisposed
high risk of cyst infection
