Q

whats the difference between reversible pulpitis and normal pulp

A

Very similar but reversible pulpitis
stands out more
The tooth is more sensitive than the
surrounding teeth but pain does not
linger

25
what is severe inflammation that will not resolve even if the cause is removed
irreversible pulpitis
26
what are the types of irreversible pulpitis
Symptomatic Irreversible Pulpitis Asymptomatic Irreversible Pulpitis
27
what pulpitis is associated with spontaneous pain (does not need to be stimulated)
symptomatic irreversible pulpitis
28
is the characteristic of pain in symptomatic irreversible pulpitis variable
yes
29
how long does symptomatic irreverisble pulpitis last
minutes to hours
30
can you locate pain of symptomatic irreversible pulpitis
yes but localization is difficult due to proprioceptive nerve fibers
31
what can prolong pain in symptomatic irreversible pulpitis
stimuli (cold, hot)
32
in advanced cases of symptomatic irreversible pulpitis, ___ provides relief and ___ worsens pain
cold = relief heat = worsens
33
describe histology of symptomatic irreversible pulpitis
1. dilated blood vessels 2. intense infiltration by neutrophils (PMNs) 3. sometimes confined areas of lysis
34
if patient complains of cold sensitivity, the first thing you think about is that pulp is ___
VITAL
35
what are 2 key symptoms that allow you to say that your pt has symptomatic ireversible pulpitis
1. Spontaneous Pain 2. Persistent pain after a stimulus has been removed
36
irreverible pulpitis is usually ___ or the patient only reports ___
asymptomatic; mild symptoms
37
in asymptomatic irreversible pulpitis, is the diagnosis presumptive?
yes
38
what pulpitis is undiagnosed many times
asymptomatic irreversible pulpitis
39
histology of asymptomatic irreversible pulpitis
1. Lymphocytes 2. Plasma Cells 3. Macrophages 4. Some PMN's 5. Less fibroblasts 6. More Collagen Fibers
40
what is an overgrowth of pulp tissue into open carious lesion
hyperplastic pulpitis (pulp polyp)
41
hyperplastic pulpitis is [small or large] carious lesion
large (open caries allows for drainage)
42
hyperplastic pulpitis occurs in [young or old] patients
young
43
hyperplastic pulpitis is usually [symptomatic or asymptomatic]
asymptomatic -> open caries allows for draininge
44
what is hyperplastic pulpitis also called
pulp polyp
45
histology of hyperplastic pulpitis
1. Connective tissue stroma 2. Chronic inflammatory cells 3. Very vascularized 4. No nerve fibers 5. Lined by stratified squamous epithelium
46
hyperplastic pulpitis requires what tx
endodontic therapy
47
what occurs when the pulp is transformed into vascularized inflammatory tissue with dentinoclastic activity
internal resorption
48
is internal resorption a type of irrevresible pulpitis
yes
49
is internal resorption symptomatic?
no! asymptomatic
50
what has PINK TOOTH syndrome
internal resorption
51
what has an irregular enlargement of canal space seen on radiographs BUT pulp tests are usually within normal range
internal resorption
52
histology of internal resorption
1. Chronic inflammatory cells 2. Multinucleated Giant Cells (Dentinoclasts) 3. Giant cells have brush like projections 4. Giant cells secrete acid 5. Howship's lacunae
53
what is the tx of internal resorption
IMMEDIATE removal of pulp tissue and institution of root canal treatment
54
what is pulpal necrosis
dead pulp because pulp is encased in rigid walls and has poor collateral circulation
55
when pulp is encased in rigid walls and has poor collateral circulation, the venules and lymphatic collapse under the increased tissue pressure leading to ___
pulp necrosis
56
does pulp necrosis mainly look dry or liquid
dry
57
if you seen bleeding, pulp is what
vital
58
___ will inevitable lead to bacterial colonization of pulp space with or without PA involvement
pulpal necrosis
59
what are the types of pulp tests
1. cold test 2. electric pulp test 3. heat test (occasional with hard to find tooth)
60
what do you do during pulp test
1. test suspected tooth 2. test other teeth for comparison (called control teeth)
61
how to do cold test
apply cold directly to tooth with cotton pellet
62
how to record response to cold test
1. No response (-) 2. Mild response (+) 3. Moderate response (++) 4. Severe response (+++)
63
how to take electric pulp test
1. Applies electrical current to tooth 2. Simply record number when patient responds 3. also use control teeth 4. use toothpaste as conducting media
64
is pulp test asymptomatic many times
yes
65
if pain is present in pulpal necrosis, it's usually from what?
periradicular tissues or partial necrosis
66
is partial pulpal necrosis painful
YES! can be very painful
67
what does pain from partial pulpal necrosis come from
from remaining pulp tissue
68
what is the last tissue to die in partial pulpal necrosis
nerve tissue
69
partial pulpal necrosis is diagnosed as what
pulpal necrosis
70
once the pulp dies in pulpal necrosis, what does it become susceptible to
bacterial invasion
71
with pulpal necrosis, bacteria and byproducts have an effect on what tissues
surrounding periapical tissues
72
is pulp calcification the same as a disease
no, it's a physiological thing
73
what are types of pulpal calcifications
1. pulp stones 2. difuse calcificaiton (denticle) 3. calcific metamorphosis
74
what pulp stone resembles dentin
true
75
what pulp stone is concentric rings of amorphous mass of calcified tissue
false
76
are pulp stones attached or free?
BOTH! attached or free
77
where are pulp stones present
pulp chamber/ coronal pulp
78
most pulp stones are true or false
false
79
diffuse calcification are present where
radicular pulp; root canal
