Q

How do you diagnose Persistent Idiopathic Facial Pain?

A

Diagnosis is via Exclusion of other causes

(due to non-specific symptoms – “poorly localised pain with widespread radiation” OR no help after several dental interventions - Ie several XLAs and still pain)

Q

What are the pharmalogical tx options for TMD?

A

● Analgesics – NSAIDs, Paracetamol or Opioids
● Corticosteroids – Iontophoresis or Intra-capsular injections
● Antidepressants
● Anxiolytics
● Sedative-Hypnotics
● Muscle relaxants

What would a typical SOCRATES look like for a patient with Trigeminal Neuralgia?
S – Normally UNILATERAL (60% right side) O – Anytime C – Flashing, Sharp, Shooting, Unbearable, Terrifying R – Distributions of the Trigeminal Nerve (first division rare) A – Weight loss T – Intermittent (Bouts last seconds, followed by pain free periods weeks-months) E – Provoking (Light touch, Eating or Talking) S – Moderate to Severe
33
What would a typical SOCRATES look for a patient with TMJD?
S – TMJ may be uni or bilateral O - Any C – Dull/Aching/Throbbing pain R – Pre/Post ear or Muscles of mastication A – Stress, Clicking, Tender muscles, Headache/Migraine T – Intermittent or constant E – Provoking (Chewing, Yawning or Opening wide) S – Mild to Moderate
34
What would a typical SOCRATES look like for a patient with Burning Mouth Syndrome?
S – Tongue, Lips, Palate (can radiate to whole mouth) O – Anytime C – Burning, Tender & “Irritating”/”Tiring” R – Whole mouth A – Feeling of Oral Dryness, Altered Taste, Depression/Anxiety T – Intermittent or constant (worse in evening) E – Provoking (Eating or Tension) S – Mild to Moderate
35
What special investigations need to be carried out for trigeminal neurlagia?
FBC MRI scan of posterior fossa to detect compression and rule out tumours and MS

What are cluster headaches?
Unilateral excruciating attacks of pain principally involving orbital, frontal and temporal regions
39
What are different disorders included in TMD?
Myofascial pain disorder TMJ disc interference disorders TMJ degenerative joint disease

Define ALLODYNIA
Pain due to a stimulus that would not normally provoke pain E.g. VZV Post-Herpetic Trigeminal Neuralgia can lead to pain touching skin or clothes
41
Define trigeminal neuralgia
Sudden, usually unilateral, severe, brief, recurring, stabbing pain in the distribution of one or more branches of the trigeminal nerve

50
What hormonal changes can cause burning mouth syndrome and how?

M>F ratio 5:1
56
What may you see in blood reports of pts with giant cell arteritis?
ESR (Erythrocyte Sedimentation Rate) above 50mm/min
