Exam 2 Practice Flashcards
irreversible pulpitis is often defined by
a painful response to cold that lingers
a test cavity…
is employed when all other tests are inconclusive
when a patient reports severe pain on biting, the percussion test should
be performed first with digital pressure
the following is the most important finding of a chronic apical abscess
draining sinus tract
you have submitted a biopsy sample from a PA lesion on which you performed surgery. The histopathology report states that lesion is composed of fibrous CT with many young “budding” capillaries. A chronic inflammatory infiltrate can be seen throughout the lesion. what is the histologic diagnosis for this lesion
PA granuloma
a tooth with normal pulp should
give a quick sharp response to cold application
which pulp vitality test cannot be performed on tooth that has a gold crown
cold application
electric pulp test
heat test
cold application and EPT????
chatgpt says all the above aren’t reliable. cannot find anything in lecture.
wha is the best approach to determine if abscess is of periodontal or endodontic origin
pulp vitality tests
you suspect tooth #18 might have endo involvement. what teeth should be used as controls for diagnostic testing?
19 and #31
which theory best explains the referred pain phenomenon
covergence theory
which teeth are most likely to refer pain to the ear
mandibular molars
which teeth are more likely to refer pain to forehead area
maxillary incisor
what is not a feature of trigeminal neuralgia
reproducible tooth pain
a paatient presents with pain in upper right quadrant. several teeth in area are sensitive to percussion and sensitive to cold. hte patient says that pain increase when they bend down. there is no caries or large restorations present. what is likely source of patient pain
referred pain from max sinus
what histologic feaure must be present for lesion to be considered an apical cyst
fluid filled cavity
crown discolorization due to calcific metamorphosis usually is
yellow
spreading pain results from extension of these to surrounding teeth and neighboring structures
inflammatory mediators
a patient that complains of severe cold sensitivity most likely has
a vital but inflamed pulp
what theory best explains sensitivity to cold
hydrodynamic theory
a patient you are examining has extensive facial swelling, tooth #11 is very sensitive to percussion there is no sensitivity to cold testing
what is the most likely pulpal diagnosis
pulpal necrosis
a patient you are examining has extensive facial swelling, tooth #11 is very sensitive to percussion there is no sensitivity to cold testing
what is the most likely PA diagnosis
acute apical abscess
a patient you are examining has extensive facial swelling, tooth #11 is very sensitive to percussion there is no sensitivity to cold testing
what is the treatment for this tooth
- endodontic therapy
- antibiotic coverage
- drainage
the pulps in teeth are undergoing active internal resorption usually are
chronically inflamed
what is not true of hyeprplastic pulpitis
it is not highly innervated
true: highly vascularized, epi lining, and contains CT
T/F: heat test is part of routine endo exam
FALSE
T/F: radiographs are used to determine what kind of PA pathology the patient has
TRUE
T/F: during pulpitis histamine is responsible for vasodilation of pulpal blood vessels
TRUE
if tooth can feel cold the pulp is
vital
if you do a cold test and the tooth is non responsive to cold application, the tooth is likely
nectrotic
if a pulp is vital, does that mean it is a healthy pulp
not always
key findings on a pulp that has irreversible pulpitis
history of spontaneous pain and prolonged lingering pain after cold application
if you are drilling on a tooth and get a pulp exposure, and the exposure site is dry that means the pul pis
necrotic
what is the most diagnostic sign/symptom of symptomatic apical perio
pain to percussion
what is the most diagnostic sign/symptom of chronic apical abscess
sinus tract
what is the best diagnosis for a tooth with apical radiolucency, a necrotic pulp and no other sign or symptoms
asymptomatic apical perio
swelling and pain is seen in
acute apical abscess
what is the radiographic appearance of condensing oseitis
radiopacity at apex of tooth
doc my tooth hurts a lot and i cant even touch is is example of
chief complaing
T/F: when dealing with patient symptoms, it is important to try and reproduce the patients symptoms
true
a percussion test will tell us if
there is inflammation in the PDL
T/F: EPT will produce patient symptoms
FALSE
T/F: a tooth with PA radiolucency is a sure sign of endo disease, therefore, pulp test are not necessary
FALSE
you are observing a PA radiolucency on radiograph. this is an example of
objective sign
what is used at creighton for cold testing teeth
refrigerant spray
you have done a cold test and determined the pulp is normal. how would you record the findings
+
what is the chief complaint
patient describing his/her symptoms in his/her own words
what does spontaneous pain mean
unprovoked pain
what is the most useful in detecting cracks ont eeth
transillumination
how would you record a normal test for percussion
-
what is used as conducting media for EPT
toothpaste
T/F: when a sinus tract is present, it should be traced with gutta-percha point and x-ray taken to see the origin
TRUE
T/F: a percussion test should be done by tapping the tooth with index finger first if not sensitive then used the mirror handle
TRUE
T/F: acute apical abscess is associated with necrotic pulp
TRUE
what can show systemic invovlement such as fever, lymphadenopathy and malaise
acute apical abscess
what is a phenix abscess
acute apical abscess with radiolucency
T/F: a sinus tract will always appear on attached gingiva
FALSE
symptomatic apical periodontitis is always associated with necrotic pulp
false
pain to cold comes frmo
the pulp
is pulpitis visible on radiograpahs
no
almost all pulp stones are
false
overgrowth of pulp tissue into open carious lesion is referred to as
hyperplastic pulpitis
a tooth more sensitive to cold than other teeth, after cold is removed from sensitive quickly disappears is called what
reversible pulpitis
T/F: clinical findings closely correelaed to histology of the pulp
FALSE
symptoms of symptomatic irreversible pulpitis
lingering pain to cold AND spontaneous pain
