Constant burning/aching pain
Fixed location
Often a fixed intensity
Genetic predisposition?
- Nerve ion channels that heal badly after injury

Physical
- TENS – occasionally helpful

Psychological
- Distraction
- Correct abnormal illness behaviour

What is the definition of atypical odontalgia?
Dental pain without dental pathology
- How difficult is this to diagnose
Distinct pattern of pain
Equal sex distribution
Pain free or mild between episodes
Intense unbearable pain
2-3 weeks duration
Settles spontaneously
Descri the treatment options ad their following effects for patient’s with atypical odontalgia?
Acute pulpitis pain
Endodontics relieves or reduces pain
- Pain returns after a short time
Extraction relieves pain
- Pain returns in adjacent tooth after a short time
Endodontics relieves or reduces pain
- Pain returns after a short time
Extraction relieves pain
- Pain returns in adjacent tooth after a short time
Patient Referred
Descri the pathway for a dentist trying to diagnose atypical odontalgia?
PRIMARY CARE – REFER!
Oral Medicine Management
Chronic strategy
- Reduce chronic pain experience
- Reduce frequency of acute episodes
Acute strategy
- Have a plan to control pain
opioid analgesics as required
high intensity/short duration
- Be prepared to extract tooth if needed
What is the definition of Persistent Idiopathic Facial Pain?
Pain which poorly fits into standard chronic pain syndromes
- Neuropathic
- CRPS
- TMD
- Trigeminal Neuralgia
- Migrainous Pain
- Atypical odontalgia
Often high disability level – autonomic component
Explain how to assess a patient with Persistent Idiopathic Facial Pai?
Believe patient
- Do not blame any associated depression for symptoms
Do not increase damage
- Surgery is not helpful!
Adopt holistic strategy
- Quality of life issues
- Pain control a bonus
- Realistic outcomes – Patient & Clinician
Use QOL/pain scores as treatment monitor
What is the definition of Oral Dysaesthesia?
Abnormal sensory PERCEPTION in ABSENCE OF ABNORMAL STIMULUS
Somatoform or Neuropathic?
- Where is the problem?
ame the 4 symptoms of Oral Dysaesthesia?
ALL modes of oral sensation involved
- Burning or ‘nipping’ feeling
- Dysgeusia
- Paraesthesic feeling
- Dry mouth feeling
ame the 4 predisposig factors for Oral Dysaesthesia?
Deficiency states
- haematinics
- zinc
- vit B1, B6
Fungal and Viral infections?
Anxiety and stress?
Gender – more women present to OM than men
What is the definition of Burning Mouth Syndrome?
Dysaesthesia most likely to be associated with haematinic deficiency
SITE important!
- Lips & tongue tip/margin = parafunction
- Multiple other sites - dysaesthesia
What is the definition of Dysgeusia?
bad taste’ - ‘bad smell’ - ‘Halitosis’
nothing detected by practitioner
nothing found on examination
REMEMBER!
- ENT causes - chronic sinusitis
- perio/dental infection
- GORD
nothing detected by patient’s partner?
What is the definition of Touch Dysaesthesia?
pins and needles’ - ‘tingling’
Normal sensation to objective testing
Pin/needle elicit pain!
CRANIAL NERVES test essential
MUST exclude organic neurological disease
MUST exclude local causes
infection
Tumour
MRI Essential – demyelination/tumour
What is the definition of dry mouth dysaesthesia?
VERY common
c/o debilitating dry mouth/‘sjogrens’
Eating OK
worse when waken at night
usually the most obviously associated with anxiety disorders
Descrie the management of dysaesthesia?
Explain the condition to the patient
- ‘pins and needles’ in the taste etc
Assess degree of anxiety
- Anxiolytic medication
- Clinical psychology
Treatment empower the patient
- Control is important
ame the types of medication for dysaesthesia?
Anxiolytic based medication
- Nortriptyline
- Mirtazepine
