Inflammatory pain Mediated by AA pathway Good surgical technique can minimise NSAID’s 3rd molar model -analgesic trials
Referred dental pain (4)
Fairly common from headache
Referred from another quadrant
Cardiac tooth pain - rare
Sinusitis
Maxillary sinusitis definition (2)
Constant burning pain with zygomatic and dental tenderness from the inflammation of the maxillary sinus
IASP 1994
Maxillary sinsusitis symptoms (4)
- C/O purulent rhinorhea
- recovery from a nasal cold and then a worsening of symptoms
- O/E purulent secretions in the nasal cavity
- ESR above 10mm per hour
Normal sinus functioning depends on (3)
- patent ostia
- satisfactory ciliary functioning
- appropriate amount of secretions
Oral dysaesthesia - aetiology (1)
Unknown
Management of oral dysaesthesia (2)
CBT improved 6/12
Oestrogen increased taste
Prognosis of oral dysaesthesia (1)
Unknown
Trigeminal neuralgia definition (1)
A sudden, usually unilateral, severe, brief, stabbing, recurrent pain in the distribution of one or more branches of the fifth cranial nerve
IASP 1994
Atypical facial pain (2)
I. present daily and persist for most or all of the day
II. should be confined at onset to a limited area of one or both sides of the face, but may spread to the upper or lower jaws and a wider area of the face and neck
III. should not be associated with sensory loss
or other physical signs
IV. Laboratory investigations should not
demonstrate relevant abnormalities
The pain may be initiated by trauma, but persist
without any demonstrable local cause
Atypical odontalgia definition (1)
Severe throbbing pain in the tooth without major pathology
IASP 1994
TMJ pain types (5)
Costens syndrome Temporomandibular joint dysfunction syndrome (TMD) Myofascial pain syndrome Facial arthromyalgia Oromandibular pain
TMJ pain definition (1)
Pain in the TMJ and muscles of mastication,
which may worsen upon chewing, possibly
leading to restricted jaw movement
after IASP 1994
Management of chronic pain (3)
- Assessment and diagnosis
- ensure no cause of concern - Explanation and reassurance
- Discuss/ suggest tx options
Biophyschological assessment (3)
Biological
Psychological - anxiety/ depression
Social context - work/ finances/ family
What is oral dysaesthesia? (1)
Burning pain in tongue from any cause
Local causes and diagnostic tools for burning mouth (7)
Bacterial - oral swabs Fungal - oral rinse for candida Allergy - patch test Geographic tongue - observe over time Parafunction - dental examination Oesophageal reflux - tooth erosion Xerostomia - salivary flow rates
Systemic causes of burning mouth (5)
< iron folate B12 Diabetes Menopause Psychogenic Cancerphobia
** Chronic pains
TMJ Neuralgic Atypical Vascular Location Temple, ear, jaws, teeth Nerve distribution Diffuse, deep ?across midline Orbit or upper face Localisation Poor, but usually unilateral Fair to good Poor Usually good Duration Weeks to years Seconds Weeks to years Minutes to hours Character Dull, continuous Lancinating, paroxysmal Dull, boring, continuous Throbbing, deep Precipitating factors Chewing, yawning Touch, wind, vibration Stress, fatigue Alcohol Signs Limited mouth opening, ?click None None Lacrimation, eye injected Aetiology Stress, parafunction Idiopathic, MS Nerve injury, stress Vasomotor, ?allergic Treatment Physiotherapy, behavioural, antidepressants Tegretol, nerve block, neurosurgery Antidepressants, behavioural Triptans
Management of oral dysaesthesia (3)
Correct deficiencies
Alter medications
Manage symptoms
Positive trials for oral dysaesthesia (5)
Topical clonazepam Antidepressants Alpha-lipoic acid Capsaicin capsule Cognitive behavioral therapy -EB
What is atypical odontalgia? (1)
Severe throbbing pain in the tooth without major pathology
What is atypical odontalgia (3)
• Pain associated with a tooth or tooth socket without any major pathology • Precipitated by dental procedures • If the tooth is extracted the pain often recurs after a few weeks at a new site
Phantom tooth pain or AO (3)
• Toothache with no dental pathology • Constant throb or ache • Dental treatment – no difference – Improvement for a week
Removal of a tooth with atypical pain –> outcomes (3)
•Pain remains same (with no tooth)
•Pain moves to adjacent teeth
•Pain in gingival tissue that previously
surrounded tooth
Aetiology of atypical odontalgia (5)
Sensitisation of nerves may occur after infection, extraction or even RCT Changes within the CNS and possibly ongoing neural activity ?? Female prevalence Tends to be older patients ?? Psychosocial factors
Abnormal pain responses and examples (4)
At the site of injury or no injury e.g. chronic
pain, abnormal pain responses can occur
e.g. phantom limb pain, AFP, traumatic lingual nerve dysaesthesia
What is hyperalgesia (1)
Stimulation is more painful
What is allodynia (1)
Non painful stimuli are painful
What is spontaneous pain (1)
Pain in absence of stimulus
Central sensitisation/ secondary hyperalgesia - changes in behaviour of central (SC) cells (4)
- Induced by tissue injury
- Increased spontaneous background firing
- Hyperexcitability to other low threshold input
- Increased size of receptive fields
Pain enhancement - wind up (1)
central, enhanced responsiveness and increased AP firing rate leading to increased perceived pain intensity
Describe atypical odontalgia (8)
Location Diffuse, deep ?across midline
Localisation Poor, does not fit anatomical boundaries of Trigeminal Nerve
Duration Weeks to years
Character Dull, boring, continuous, can be throbbing, aching “like a toothache”
Precipitating
factors
Stress, fatigue, nil
Signs None
Aetiology Nerve injury, stress
Treatment Antidepressants, behavioural (CBT)
LA block does not help
Possible types of therapy for atypical odontalgia (4)
•stress management - ? through GMP •relaxation / hypnosis •cognitive behaviour therapy, CBT (probably includes both of above) •psychological help for other problems inc. talking therapy
What is CBT? (4)
It is a way of talking about:
•how you think about yourself, the world and
other people
•how what you do affects your thoughts and
feelings.
CBT can help you to change how you think
(‘Cognitive’) and what you do (‘Behaviour’).
These changes can help you to feel better
Analgesic antidepressant drugs (3)
• As helpful with chronic pain with known
pathology as with unknown pathology or
aetiology
e.g.Chronic arthritis, post herpetic neuralgia
• Mainstay of management of AFP/AO
• Amitriptyline/nortriptyline 10-100mg nocte
Abnormal signs (3)
• Abnormal cranial nerve testing results
– Abnormal sensations
– Abnormal responses
• Vomiting/Headache - ICP
