17
Q

what should you do if a patient comes to the dentist with symptoms closely related to muscle hyperactivity

A

-educate the patient regarding the relationship between emotional stress, muscle hyperactivity and the problem
- refer to therapist
-once they understand problem, anxiety will be reduced which often reduces pain

18
Q

what does “if it hurts dont do it” mean with food

A

encourage pt to eat softer foods, take smaller bites, and chew slowly

19
Q

what other habits can aggrevate TMD symptoms

A

biting on objects
chewing on ice
heavy gum chewing

20
Q

what are the two types of relaxation therapy and define them

A
  • substitutive: a substitution for stressful events or an interposition between them (exercise, activities they enjoy)
  • active relaxation: therapy that directly reduces muscle activity (train sympomatic muscles to relax, biofeedback, negative feedback)
21
Q

what is an effective way to start stress reduction therapy

A

positive doctor patient relationship

22
Q

how should stress reduction therapy be approached

A

present stress as a factor early in tx so the patient can appreciate the relationship between pain, emotional stress and the dental procedure

23
Q

in the case of macrotrauma, definitive therapy is ____

A

of little use because the trauma is no longer present

24
Q

in the case of microtrauma, definitive therapy is ____

A

necessary to curtail the trauma

25
Q

definitive therapy would consist of ____

A

developing orthopedic stability

26
Q

there is _____ between the amount of bruxing activity and pain

A

no correlation

27
Q

how should patient education begin

A

by informing the patient that the teeth should only contact during chewing, speaking and swallowing

28
Q

what is nocturnal bruxism influenced by

A

factors such as emotional stress levels and sleep patterns

29
Q

what type of therapy is useful in providing immediate relief of the symptoms

A

supportive therapy

30
Q

what are the 2 types of supportive therapy

A

pharmacological therapy and physical therapy

31
Q

what are the common drugs used for pharmacological therapy

A

-analgesics
- antiinflammatories
- muscle relaxants
- anxyolitcs
-antidepressants
-anticonvulsives

32
Q

what are the modalities of physical therapy

A
  • thermotherapy: heat is prime mechanism because it increases circulation
  • coolant therapy: cold relaxes the muscles and relieves the pain. should not be left on longer than 5 to 7 minutes
33
Q

what is ultrasound therapy

A

method of producing an increase in temperature at the interface of the tissues and therefore affects deeper tissues than does surface heat

34
Q

what should ultrasound therapy be used in conjunctio with

A

surface heat therapy

35
Q

what is electrogalvanic therapy

A

utilizes the principle that an electric current will cause a muscle to contract
-rhythmic electrical impulse is applied to the muscle creating repeated involuntary contractions and relaxation

36
Q

what is transcutaneous electrical nerve stimulation

A
  • continuous stimualtion of cutaneous nerve fibers at a subpainful level
  • uses low votlagge, low amperage current of varied frequency
37
Q

what are manual techniques

A

-soft tissue mobilization: superficial and deep massage
- joint mobilization: gentle distraction of the joint

38
Q

what is muscle conditioning

A

exercises that can help restore normal function and range of movement

39
Q

when should assisted muscle stretching be done

A

when there is a need to regain muscle length
- but should never be sudden or forceful

40
Q

A

-stimulation of certain areas that cause the release of endogenous opioids which reduces painful sensations
