Answer 3

periodontal disease
fractured teeth
tooth resorption
malocclusion

Question 4

define periodontal disease

Answer 4

disease of the tissues that support and anchor the teeth: gingiva, cementum, alveolar bone, and periodontal ligament

Question 5

what steps are required to assess periodontal disease?

Answer 5

1. dental probing
2. intraoral radiographs

Question 6

what is the periodontum?

Answer 6

supporting structures of the teeth: the periodontal ligament, cementum, alveolar bone, and gingiva

Question 7

what is the cementoenamel junction?

Answer 7

where the enamel transitions into cemetum

Question 8

what is the normal peridontal pocket size in dogs and cats?

Answer 8

dogs: 0-3mm
cats: 0-1mm

Question 9

how do you measure gingival recession?

Answer 9

measure mm from cementoenamel junction to where the gingival margin is

Question 10

total attachment loss=

Answer 10

periodontal pocket + gingival recession

Question 11

normal bone height is:

Answer 11

from the cemento enamel junction to the root apex

Question 12

bone loss is when the bone height is..

Answer 12

below the cemento enamel junction

Question 13

bone loss is measured how?

Answer 13

as a percent of normal bone height

Question 14

describe stage 1 periodontal disease and what is the treatment?

Answer 14

gingivitis only with no attachment loss

treatment: dental cleaning

Question 15

describe stage 2 periodontal disease and what is the treatment?

Answer 15

less than 25% attachment loss present
treatment: dental cleaning and root planing

Question 16

describe stage 3 periodontal disease and what is the treatment?

Answer 16

25-50% attachment loss
treatment: dental cleaning and root planing, OR extraction OR referral for guided tissue regernation

Question 17

describe stage 4 periodontal disease and what is the treatment?

Answer 17

more than 50% attachment loss
treatment: extraction

Question 18

how do you treat tooth resorption in cats?

Answer 18

extraction, cant really do much else :(

Question 19

what are some clinical signs suggestive of a tooth resorptive lesion?

Answer 19

most commonly nothing at all

others: halitosis, drooling, dropping food, sneezing, not wanting to eat, head shaking, jaw chattering, etc

Question 20

in order to classify tooth resoprtion, you need

Answer 20

radiographs!!

Question 21

the STAGE of a resoptive lesions is…

Answer 21

how deeply it penetrates the tooth

Question 22

describe stages 1-5 for tooth resoprtion

Answer 22

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

Question 23

the TYPE of a resorptive lesions is…

Answer 23

how the roots behave

Question 24

describe the types 1-3 for tooth resorption

Answer 24

1: roots are in tact
2: roots are resorbing
3: a combination (multi rooted teeth)

Question 25

how do you treat resorptive lesions based on the stage?

Answer 25

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

Question 26

how do you treat resorptive lesions based on the TYPE?

Answer 26

type 1: extraction including the roots
type 2: crown amputation because roots are not in tact
type 3: combination treatment

Question 27

what stage and type of resorptive lesions is this and what is the treatment?

Answer 27

stage 3 since it’s into the pulp
type 1, roots are in tact

extraction

Question 28

what stage and type of resorptive lesions is this and what is the treatment?

Answer 28

stage 4: most of tooth structure is gone
type 2: roots are gone

crown amputation

Question 29

what stage and type of resorptive lesions is this and what is the treatment?

Answer 29

stage 5: on the one side, tooth nearly gone
type 3: one root gone, the other in tact

combination tx

Question 30

what is your checklist for if you can do a crown amputation or not?

Answer 30

1. root resorption is present and the root is being replaced by bone
2. there is no stomatitis
3. there is no endodontic disease (aka the pulp is not infected, if you see the pulp exposed, you need to extract)
4. there is no advanced periodontal disease
