old endo midterm Flashcards
Normal healing
RP
return to normal condition
RP
test not routinely done
says EPT
if doesnt have EPT put hot thermal?
untreated pulpal infections can become life-threatening
true
first thing you do when thermal testing
establish baseline
chronic infections favor
anaerobic flora
base line with how many teeth
2-3
start testing with percussion on suspected tooth
false
cold test with endo ice on q tip
false
cotton pellet
proprioceptors
PA
in PDL not pulp
Chronic infections with DST rarely become emergent
true
Which one lingers
IP
Which one would lead to PA lesion, select all that apply
asymptomatic and symptomatic irreversible pulpitis and necrotic
it can take weeks for radiolucency to show up. All medullary bone can be destroyed,
need 40% of cortical gone before it will show up on a x-ray.
both true
Figured out bacteria were anaerobic gram – in an infection.
true
Without bugs there would be no caries.
true
first thing you do with new patient
take medical history
If you have a tooth with no restoration but pain what should you do.
Quiz patient about recent/ history of trauma and use a tooth slooth/ transilluminator
For most endodontic diagnosis, what do you have to do
clinical examination and clinical testing
For most endodontic diagnosis, what do you have to do
clinical exam and clinical testing
for endo dx, you need pulpal and PA
true
SLOB
shift cone mesial and the DL is most mesial
purpose of BW
restorabilitiy
objective of dx or something
find etiology of CC and confirm its of endodontic origin
theory of pain
branstromm’s hydrodynamic
incorrect statement- necrotic spread to adjacent teeth
if patient points to specific tooth
there may be periapical inflammation - true
endo and implants have same criteria
false
patient cc need to be in own words
true
If patient has other issues after doing history and exam
refer
Endodontists recommend leaving tooth open
false
Systemic antibiotics to prevent swelling and fever
TRUE
most common portal of entry
leaky caries/restoration
better to do percussion test on SIP before taking radiographs
true
acute fibers
a fibers
chronic fibers
c fibers
Mistaken for LEO
Aberrant, normal anatomic landmark, oral manifestation of systemic disease
You have to confirm your diagnosis before you begin treatment plan
true
start percussion on suspected tooth
false
if no other damage to tooth, suspect crack and do tooth slooth and transillumination
true
most common cause
bacteria
DST, minimal swelling
chronic apical abscess
infection below mandibular molar and below muscle is localized swelling
false- cellulitis
antibiotics are only prescribed to pt with
swelling and temp
Patients chief complaint is pain with cold and chewing. There is an MO composite on #3.
Hypersensitivity to cold with lingering pain. Response to percussion but not palpation.
What is the Periapical diagnosis?***
symptomatic apical periodontitis
30 mesial broke. WNL to cold without lingering pain. No pain to percussion or palpation.
Radiograph shows deep mesial caries with intact lamina dura. What is the periapical
diagnosis?
within normal limits
which nerve fiber transmits acute pain
a fibers
12 awoke patient in the night. No pain to cold or EPT. Pain to percussion and buccal
palpation. Buccal vestibule is swelling. Radiograph shows thick PDL. What is the PA Dx?
AAA for PA
pulp necrotic for pulp
What is the difference between Reversible pulpitis and Symptomatic reversible pulpitis?
RP no pain lingers
SIP has lingering pain
According to SOAP, A means:
assessment
Where are cold and EPT performed?
buccal surface
20 has PARL. WNL to cold, percussion and palpation. What should you do?
take angle radiograph
Loss of lamina dura is an indicated by a radiolucency.
true
Patient has pain in upper right teeth, 2-8. All teeth are WNL. #30 hypersensitive to cold with lingering pain. why cant pt tell location
because only pain fibers are present and not specific (in pdl)
means pulpal
antibiotics cannot treat necrotic pulp because
blood supply is compromised
pulp contains no mechanoreceptors, only pain/nociceptors
false BOTH
What is the most cracked tooth?
mand 2nd molar
Systemic antibiotics are used when?
- Spreading infection (cellulitis)
systemic fever
NaOCl sterilizes pulp. works in 15 mins
false false
disinfects 30 mins
all cases of compromised pulp should be treated with
rct
