Q

Emotional Stress

A
  • Hypothalamus, Reticular system, Limbic system=Emotional Stress
  • Stress activates HPA axis (Hypothalamic-Pituitary-Adrenal axis)
    • prepares the body to respond to stress via ANS
  • ⇡ gamma efferent activity (ANS)→ muscle spindles contract

Q

Masticatory Muscle Activity: Functional vs Parafunctional Activity

A
  • Functional:
    • Chewing
    • Speaking
    • Swallowing
  • Parafunctional: can happen subconsciously
    • Clenching
    • grinding
    • cheek biting
    • tongue thrusting

Q

TMD: A patient may present with:

A
  1. Muscle disorder Only
  2. Intracapsular disorder only
  3. Primary intracapsular + Secondary Muscle
  4. Primary Muscle + Secondary Intracapsular
  5. Both→ indépendant of each other

Q

TMD: Event

A
  • interruption of normal muscle function
  • Local:
    • tooth fracture
    • restoration in supraocclusion
    • tissue damage from injection
  • Systemic:
    • Up regulation of ANS:
      • ⇡ emotional stress
    • Down regulation of descending inhibitory system
      • Systemic disorder
      • Illness
      • Fatigue
      • Diet

Q

Protective Co-Contraction: General

A
  • Masticatory M. 1st response to an event
    • Normal CNS reflex to injury or threat of injury
  • Antagonistic m. groups fire to protect injured parts
    • Open Mouth: ⇡ elevator m. activity
    • Close mouth: ⇡ Depressor m. activity

Q

Protective Co-Contraction: Etiology

A

Altered Sensory or Proprioceptive input

  • Change occlusal condition
    • poorly fit crown→high occlusal contact
  • Constant Deep pain

Q

Protective Co-Contraction: Treatment

A
  • do NOT treat the muscle (PCC=normal CNS response)
    • TREAT the etiology
  • Supportive Therapy:
    • restrict use of mandible w/in painless limit
    • Soft diet
    • NSAIDs

Q

Local Muscle Soreness: General

A
  • Non-inflammatory myogenous Pain disorder
  • Muscles 1st response to continued PCC
    • initial response to muscle overuse/fatigue
17
Q

Local Muscle Soreness: Etiology

A
  • continued PCC
    • secondary to alteration in local structures
  • Continued constant deep pain
  • Local tissue trauma
  • Unacustomed see of muscle
    • delayed onset local muscle soreness
  • ⇡emotional stress
18
Q

Local Muscle Soreness: Clinical Presentation

A
  • ⇣ Mandibular ROM
    • can’t achieve Full ROM
  • Minimum pain at rest
  • ⇡ pain w/fxn
  • Actual muscle weakness
  • Muscle tenderness to palpation
19
Q

Local Muscle Soreness: Treatment

A
  • Eliminate source of deep pain input
  • restrict use of mandible to painless limits
  • soft diet
  • cognitive awareness
  • stress management
  • NSAIDs
  • stabilization appliance
20
Q

Myofascial Pain: General

A
  • Regional myogenous pain
  • Trigger Points: local areas of firm, hypersensitive bands of muscle
    • Active:
      • always tender/painful
      • compressed=pt recognize pain
      • prevent fulll lengthening of muscle
      • weakens muscle
      • produces local twitch response when stimluated
    • Latent:
      • clinically quiescent (silent)
      • pain only when palpated
      • have taut muscle band
        • stiff muscle
        • restricted ROM
21
Q

Myofascial Pain: Etiology

A

Unclear

  • continued deep pain input
  • ⇡ emotional stress
  • Sleep Disturbance
  • Local factors:
    • habits
    • posture
    • muscle strians
  • Systemic factors:
    • ntr deficiencies
    • poor physical condition
    • fatigue
    • viral infection
  • idiopathic trigger pt mechanism
