Dentistry Flashcards
what is periodontal disease the result of?
inflammatory response to dental plaque
how many dogs does periodontal disease affect?
87% over 3 years of age
how many cats does periodontal disease affect?
70% over 3 years of age
what is the earliest sign of periodontal disease?
ginvivitis
can gingivitis be reversed?
yes
what happens if gingivitis is left untreated?
will progress to periodontitis
is periodontitis reversible?
no
what is the cause of periodontal disease?
accumulation of plaque on the tooth surfaces
what is plaque?
a biofilm that accumulates on all surfaces of the teeth
what is plaque comprised of?
salivary mucopolysaccharides and glycoproteins
bacteria
oral debris
what oral debris can form plaque?
food remnants
desquamated epithelial cells
occasional inflammatory cells (if infection present)
what is calculus?
mineralised plaque
what always covers calculus?
plaques
what is calculus an ideal location for?
dental biofilm to stick to
does calculus cause gingivitis?
no
what does cause gingivitis?
plaque
what is gingivitis?
reversible plaque induced inflammation limited to the gingiva
what are the clinical signs of gingivitis?
inflammation
reddening (erythema)
often bleeding of gingival margin
halitosis
how is severity of gingivitis decided?
graded 1-3
what is grade 1 gingivitis?
mild
what are the clinical signs of grade 1 gingivitis?
redness
swelling
no bleeding on probing
what is grade 2 gingivitis?
moderate
what is grade 3 gingivitis?
severe
what are the clinical signs of moderate (G2) gingivitis?
redness
swelling
bleeding on probing
what are the clinical signs of severe (G3) gingivitis?
redness swelling bleeding on probing ulceration spontaneous bleeding
how is gingivitis prevented?
removal of accumulated calculus (periodontal dental treatment)
improved oral hygeine
how can oral hygiene be improved?
oral antiseptics
short term antibiotics
dietary change
tooth brushing
how is gingivitis prevented?
daily oral hygiene by owners from a young age
when may periodontitis develop?
untreated gingivitis
what does inflammation in periodontitis involve?
gingiva but also the surrounding periodontal ligament, alveolar bones and cementum
what will happen if periodontitis is left untreated?
teeth will fall out
what are the clinical signs of periodontitis?
dental deposits halitosis mucosal and glossal ulcers gingival recession bleeding dysphagia pain
describe clinically healthy teeth and gums with no gingivitis
no signs of gingival inflammation
no periodontal disease clinically evidant
describe the presentation of a tooth with gingivitis only (no periodontitis)
gingivitis
no attachment loss
height and architecture of the alveolar margin are normal
describe the signs of early periodontitis
less than 25% attachment loss (probing or radiographic assessment)
at most grade 1 furcation involvement in multirooted teeth
early radiographic signs of periodontitis
what are the signs of moderate periodontitis?
25-50% attachment loss (probing or radiography)
grade 2 furcation involvement in multirooted teeth
how is attachment loss in teeth assessed?
probing
radiographs
describe the signs of advanced periodontitis
more than 50% attachment loss
grade 3 furcation involvement in multirooted teeth
what is furcation involvement?
furcation involvement refers to bone loss at the branching point of the roots
in what type of teeth can furcation involvement during periodontitis occur?
Furcation involvement can only be present on multi-rooted teeth
where are dentals most often carried out?
prep
why are dentals most often carried out in prep?
dirty procedure
what table is needed for dentals?
grid over the top of a tray to catch water/blood etc (Torbridge set up)
what should be looked for during a conscious clinical dental exam?
halitosis
dysphagia
hypersalivation
why is the conscious dental exam of limited value?
gingivitis may be an indication of periodontitis which requires investigation under GA
what should be assessed during a conscious clinical dental exam?
gingival health rather than presence of calculus
why is the presence of calculus not of interest during a conscious dental exam?
will be removed during a scale and polish
what are the main steps involved in a dental?
exam
recording
scale and polish
how many teeth should adult dogs have?
42
how many teeth should adult cats have?
30
what level of sedation is needed for a dental?
full GA
how should the patients airway be managed during a dental?
tracheal intubation
why is a throat pack needed during a dental?
prevention of aspiration of irrigation fluids and debris
what is used during a dental to prevent aspiration?
mouth pack
how can the patient be positioned to aid the vet and reduce aspiration risk?
head down slightly
what should the surface of the dental table be like?
grid with a trough/sink underneath to catch water/blood
what drugs will be needed during a dental?
IVFT - considered
analgesia
what analgesia will be used for dentals?
methadone (opioid)
CRI - ketamine
local blocks - lidocaine/bupivicaine
where may local blocks be placed?
infraorbital
what must be prevented in dental patients?
hypothermia as tend to get wet and cold
what should be examined once the patient is under GA before the dental is started?
head shape
occlusion
each individual tooth (all surfaces)
oral cavity
what parts of the oral cavity should be examined during a dental?
lips cheeks tongue hard and soft palate larynx tonsils MM
what is occlusion in dentistry?
how the teeth come together (the bite)
what does AB stand for?
abrasion
what is abrasion caused by?
action of something abrasive against the teeth (e.g. a sandy ball)
what does AT stand for?
attrition
what is attrition caused by?
teeth grinding/knocking against teeth
what does Ca stand for?
caries lesion
what does CCF stand for?
complicated crown fracture
what does ED stand for?
enamel defect
what does GH stand for?
gingival overgrowth
what does GR stand for?
gingival recession
what does NAD stand for?
no abnormality detected
what does PE stand for?
pulp exposure
what does TR stand for?
tooth resorption
what does UCF stand for?
uncomplicated crown fracture
what does # stand for?
fracture
in the modified Triadan system what does the first number stand for?
the quadrant of the mouth
