Functional Disorders of the Dentition and Other Signs and Symptoms Flashcards
___ is an unusual degree of movement of a tooth within its bony socket
mobility
how does periodontal disease contribute to mobility?
loss of bony support
T or F:
heavy occlusal forces cause cellular breakdown within the periodontal ligament space surrounding the root, creating apical migration of the epithelial attachment of the gingiva
false
does not create apical migration of the epithelial attachment of the gingiva
do heavy occlusal forces cause permanent alteration in the gingival attachment or supportive structures of the tooth?
no
what does primary traumatic occlusion cause?
mobility resulting from unusually heavy occlusal forces
what acts as support for primary traumatic occlusion?
normal periodontal supportive structure
when is primary traumatic occlusion reversible?
when heavy occlusal forces are eliminated
what is secondary traumatic occlusion caused by?
unusually heavy occlusal forces acting on already weakened periodontal supportive structures
T or F:
periodontal disease is already present in primary traumatic occlusion
false
it is present in secondary traumatic occlusion
what are mandibular tori thought to be associated with?
originally thought to be associated with heavy loading of the teeth, or interplay between genetic factors and environmental conditions
describe pulpitis when the etiology is due to heavy occlusal forces
- complaints of hot or cold sensitivity, usually of short duration, reversible but can become irreversible
- rule out caries and recent dental procedures
tooth wear is seen in up to ___% of general dental patients
95%
tooth wear is predominantly a result of ___
parafunctional activity
tooth wear often matches to eccentric positions assumed during ___
nocturnal bruxism
T or F:
tooth wear is normally asymptomatic
true
T or F:
there is strong evidence that tooth wear is associated with TMD
false
there is some thought that tooth wear is associated with infringement of the ___ during mastication
functional envelope of motion
T or F:
primary headache is an actual disorder
true
what are 3 causes of primary headaches?
- migraine (neurovascular pain)
- tension-type (origin in muscle tissues)
- trigeminal autonomic cephalgia
tension-type headaches make up ___% of all headaches
80%
T or F:
secondary headache is an actual disorder
false - they are caused by another disorder
___ headache is a common symptom associated with TMD
secondary
T or F:
various treatments can significantly decrease secondary headache pain
true
what are 4 terms that describe migraines?
severe, pulsating, unilateral, debilitating
migraines are described as ___
neurogenic inflammation of the cerebral vessels
T or F:
migraines appear to have a genetic component, with men affected more than women
false
while migraines appear to have a genetic factors, women are actually more affected than men
what are 3 symptoms of migraines?
nausea, photophobia, and phonophobia
what is the typical duration of migraines?
4-72 hours
migraines are often relieved by ___
sleep
migraines are preceded by ___, about how long before the migraine begins?
aura, about 5-15 minutes before the pain begins
what is the luminous phenomena associated with migraines?
flashes, sparks, or zigzags (teichopsia)
T or F:
migraines are a triggering mechanism from TMD pain
true
can successful treatment for TMD pain reduce frequency of migraine attacks? is it a true cure?
yes, it can reduce the frequency, but it is NOT a cure
what is the cure for migraines?
although successful treatment of TMD can reduce the frequency of migraines, medical treatment (prescription and education) is required to cure it
tention-type headaches are a ___, ___, ___ pain
constant, steady, aching pain
are tension-type headaches usually debilitating?
no - patients report they can perform daily activities
T or F:
tension-type headaches are bilateral, and migraines are unilateral
true
T or F:
it is common for tension-type headaches to be accompanied by auras and nausea
false
T or F:
myofascial pain/trigger point pain headaches are tension-type headaches of myofascial pain origin, and are heterotopic
true
otologic symptoms of TMJ pain present as ___
ear pain perceived more posteriorly
describe “fullness or stuffiness” associated with otologic symptoms of TMJ pain
eustachain tube and tensor veli palatini failure to equalize air pressure
T or F:
otologic symptoms of TMJ pain can be due to tensor tympani malfunction
true
describe the relationship between tinnitus/vertigo and TMJ pain
- altered hearing as a result of protective co-contraction
- innervation of the 5th cranial nerve (trigeminal nerve) can be associated through central excitatory effects
- TMD therapy may reduce otologic symptoms
