Dentistry 1 Flashcards
what are clinical signs of oral/dental pain?
most common: nothing at all!
ptyalism, dropping food, jaw chattering, bruxism, head shaking, face rubbing, sneezing, not wanting to eat, weight loss, depression, etc
tooth resorption is something that happens most commonly in
cats
what are the most common (4) causes of oral pain in dogs and cats?
periodontal disease
fractured teeth
tooth resorption
malocclusion
define periodontal disease
disease of the tissues that support and anchor the teeth: gingiva, cementum, alveolar bone, and periodontal ligament
what steps are required to assess periodontal disease?
- dental probing
- intraoral radiographs
what is the periodontum?
supporting structures of the teeth: the periodontal ligament, cementum, alveolar bone, and gingiva
what is the cementoenamel junction?
where the enamel transitions into cemetum
what is the normal peridontal pocket size in dogs and cats?
dogs: 0-3mm
cats: 0-1mm
how do you measure gingival recession?
measure mm from cementoenamel junction to where the gingival margin is
total attachment loss=
periodontal pocket + gingival recession
normal bone height is:
from the cemento enamel junction to the root apex
bone loss is when the bone height is..
below the cemento enamel junction
bone loss is measured how?
as a percent of normal bone height
describe stage 1 periodontal disease and what is the treatment?
gingivitis only with no attachment loss
treatment: dental cleaning
describe stage 2 periodontal disease and what is the treatment?
less than 25% attachment loss present
treatment: dental cleaning and root planing
describe stage 3 periodontal disease and what is the treatment?
25-50% attachment loss
treatment: dental cleaning and root planing, OR extraction OR referral for guided tissue regernation
describe stage 4 periodontal disease and what is the treatment?
more than 50% attachment loss
treatment: extraction
how do you treat tooth resorption in cats?
extraction, cant really do much else :(
what are some clinical signs suggestive of a tooth resorptive lesion?
most commonly nothing at all
others: halitosis, drooling, dropping food, sneezing, not wanting to eat, head shaking, jaw chattering, etc
in order to classify tooth resoprtion, you need
radiographs!!
the STAGE of a resoptive lesions is…
how deeply it penetrates the tooth
describe stages 1-5 for tooth resoprtion
1: loss of cementum and enamel but has not reached dentin
2: extends into the dentin
3: extends into the pulp cavity
4: extensive loss of tooth structure
5: complete loss of the crown
the TYPE of a resorptive lesions is…
how the roots behave
describe the types 1-3 for tooth resorption
1: roots are in tact
2: roots are resorbing
3: a combination (multi rooted teeth)
how do you treat resorptive lesions based on the stage?
stage 1: very difficult to recognize and youll never see it
stages 2-4: extraction
stage 5: tooth is already gone, can’t really extract this
how do you treat resorptive lesions based on the TYPE?
type 1: extraction including the roots
type 2: crown amputation because roots are not in tact
type 3: combination treatment
what stage and type of resorptive lesions is this and what is the treatment?
stage 3 since it’s into the pulp
type 1, roots are in tact
extraction
what stage and type of resorptive lesions is this and what is the treatment?
stage 4: most of tooth structure is gone
type 2: roots are gone
crown amputation
what stage and type of resorptive lesions is this and what is the treatment?
stage 5: on the one side, tooth nearly gone
type 3: one root gone, the other in tact
combination tx
what is your checklist for if you can do a crown amputation or not?
- root resorption is present and the root is being replaced by bone
- there is no stomatitis
- there is no endodontic disease (aka the pulp is not infected, if you see the pulp exposed, you need to extract)
- there is no advanced periodontal disease
