Q

AAP (asymptomatic apical periodontitis)

A

inflammation/destruction of periodontium
pulpal origin, pulp is non vital
-no sensitivity to percussion/palaption
-radiolucency seen w/ no clinical symptoms
-LEO 100% of the time, no pain

Q

AAA (acute apical abscess)

A

inflammatory rxn to pulpal infection
pulp is necrotic
RAPID onset of pain, swelling, tooth tender to pressure/percussion
pus formation
SWELLING & FEVER
-may or may not see PARL
-NO DST
-can lead to cellulitis

Q

CAA (chronic apical abscess)

A

gradual onset
little to no discomfort or pain
no sensitivity to percussion/palpation/biting
no swelling or fever, no pain
will see PARL always
DISTAL SINUS TRACT ALWAYS PRESENT

17
Q

CO (condensing osteitis)

A

diffuse RADIOPAQUE lesion
local bony rxn to a low grade inflammatory stimulus
-bone formed, not being resorbed
-asymptomatic, no tx (monitor)

18
Q

craze lines

A

vertical lines in enamel
not a concern

19
Q

fractured cusp

A

may be restorable
variable injury
transilluminate to see

20
Q

cracked tooth
greenstick fracture

A

most common site is mand. 2nd or 1st molar, then max premolar
sharp pain upon biting then relief
pulp is usually vital at first

21
Q

vertical root fracture

A

J shaped lesion on radiograph
drop off pocket

22
Q

every tooth needs how many diagnoses?

A

2!
pulpal
peri-radicular

23
Q

1st question to ask Pt?

A

what is your CC
best way to determine is to reproduce CC
can they localize source of pain?
if not, probs pulpal
(diffuse pain = pulpal)

24
Q

what is the objective of clinical testing?

A

find and confirm the etiology of Pt CC

25
Q

how does UMKC perform cold testing?

A

use Endo Ice with cotton pellets on affected and surrounding teeth

26
Q

5 types of clinical testing? (performed based on CC)

A

thermal: hot/cold sensitivity
EPT: only if pulpal status is in doubt, not routine)
percussion: tapping w/ mirror for PDL sensitivity
palpation: touching of gingival tissue
probing and mobility: perio health

27
Q

required radiographs? 3 minimum

A

straight on PA
Shift shot PA (M or D)
BWX

28
Q

3 basic conditions of the Pulp

A

normal (WNL)
inflamed:
-reversible (no tx or symptomatic tx)
-irreversible (pain lingering, spontaneous, symptomatic or asymptomatic)
infected:
-tooth heading for necrosis, MO infection

29
Q

why do you always test the tooth plus 2-3 adjacent teeth?

A

to establish a baseline first

30
Q

what are 3 possible outcomes of RP?

A
  1. if treated properly, return to normal
  2. may remain RP symptomatic
  3. may deteriorate to SIP or AIP
31
Q

what will lead to necrotic pulp?

A

inflamed or infected pulp
SIP and AIP if left untreated

31
Q

you can diagnose from radiographs alone

A

NEVER

32
Q

what follows pulpal necrosis?

A

the disease spreads rapidally peri-apically
-tooth becomes percussion sensitive
-spontaneous pain occurs
-may occur before radiographic evidence is seen

33
Q

how do we see radiolucency at apex

A

bacteria @ apex send signals to bone/osteoclasts that cause it to be resorbed

34
Q

when does a PARL become visible radiographically?

A

when 40% of the cortical bone is destroyed
-100% of medullary bone can be destroyed and still no lesion will be seen

35
Q

is all peri-radicular inflammation sensitive to percussion?

A

YES
-purely pulpal pain is not
-mechanoreceptors in PDL not in pulp
-percussion pain means infection has reached peri-apical tissues
