DEFINITIONS Emergency means sudden occurrence or

unplanned negative or positive event.

Dental emergency is therefore dental conditions that may occur suddenly and requires dental professional intervention.

Illinois State Dental Society defined dental emergency as an oral condition that occurs suddenly and creates an urgent need for professional consultation and or treatment. These clinical conditions may include haemorrhage, infection, pain, and trauma

Page 4: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

However, for the topic we are concerned with today; Dental emergencies, will be tailored to the emergencies associated with dental profession.

By this it will be all encompassing i.e. Dental emergency as may occur in the dental clinic or outside the Dental clinic as may be explained latter.

Page 5: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

INTRODUCTION Dental emergencies though relatively rare,

are very important because precise and adequate handling is very essential to avoid severe complications and mortality.

The relatively rarity of dental emergencies is due to the ambulatory nature of dentistry so dental surgeons could be caught unawares esp. those that occur on the dental chair.

Hence adequate preparations and high index of suspicion on every patient during practice is very important and recommended.

Page 6: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

Thorough assessment of every patient and taken into cognizance the relevant findings before treatment is commenced will reduce incidence to the barest minimum.

The goals of the dental practitioner is to develop a sense of vigilance and anticipation to enable one respond to an urgent medical or dental needs in a reasonably confident and efficient fashion when it occurs as prevention is far better and cheaper than cure.

Page 7: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

CAUTION It is estimated that about 90% of

emergencies can be prevented. This means that 10% will occur in spite of our best efforts!!!

SOURCES OF DENTAL EMERGENCIES

This can be grouped into three major groups for the purpose of this discussion.

Arising from: 1. Patients 2. Dental Treatment 3. Trauma

Page 9: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

THOSE ARISING FROM PATIENTS:

(a) Attitude to dental care – Late, poor or never dental attendance (b) Application of self medications eg Toxins (touch and go, battery acids, aspirin, etc).

(c) Exercepated patients’ dental conditions eg toothache from untreated diseased tooth or teeth, cancers, abscesses etc.

Page 10: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

THOSE ARISING FROM PATIENTS:

(d) Unidentified or poorly managed medical conditions• Diabetes mellitus(Hyper/Hypo glycaemia), • Hypertension, • Ischaemic Heart disease (Angina pectoris/myocardial

infarction)• Cardiac Arrest, • Cerebrovascular Accident, • Fits/seizures, • Anaphylaxis, • Adrenal insufficiency, • orthostatic hypotension{dizzyness in upright position}, • Asthmatic attack.• Psychiatric conditions

Page 11: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

THOSE ARISING FROM DENTAL TREATMENT:

Broken tooth/teeth(retained roots) Post extraction haemorrhage Foreign bodies (swallowed denture), fish bones, broken fillings Post extraction trauma/swellings Endodontics Periodontal diseases(gingivitis) Others emanating from reaction of patient to treatment Fears and apprehensions – Fainting/ vasovagal syncope.

Page 12: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

THOSE ARISING FROM TRAUMA:

Maxillofacial Injuries/FracturesLacerations - Avulsion - Tooth displacement - Fracture of teethThese could be from RTA, domestic violence, playground or sports injury etc.

Page 13: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

TYPES OF DENTAL EMERGECIESThis can be grouped into two major parts: (a)Emergency occurring within the clinic: (i) Loss of consciousness(LOC) in the Dental Clinic; This could be as a result of

fainting/vasovagal syncope. Starvation(hypoglycaemia) – as a result

of Patient not taken meals at home before coming for dental treatment.

Page 14: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

TYPES OF DENTAL EMERGECIES Fit/seizures Anaphylaxis Adrenal Insufficiency Asthmatic attack Inhaled foreign bodies Psychiatric(Hyperventllation Syndrome)

Page 15: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

Fear/anxiety as a result of the sight of

dental gadgets and presumed fear of dental pain.

Diabetes Mellitus(hypoglycaemia/hyperglycaemia)

Ischaemic Heart disease(Angina pectoris/myocardial infarction).

Cardiac Arrest. Cerebrovascular Accident.

Page 16: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

FAINTING/VASOVAGAL SYNCOPY Defined as sudden loss of consciousness(LOC) due

to cerebral hypoperfusion. It is most common of LOC in the Dental Clinic. Patient is usually a fit able bodied young Man! Causes: Anxiety,pain,fatigue,high temperature and

humidity.

Presentation: Premonitory dizziness,weakness,nausea, Pallor, cold moist skin and then LOC.

Page 17: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

MANAGEMENT:

Lay patient on the dental chair and elevate the chair downwards to allow easy blood flow to the brain.

Loosen tight fittings, clothings. Lay Patient flat or in Trendelenborg

position. Recovery occurs within 3 minutes

otherwise consider other likely cause of LOC.

May need to reschedule appointment.

Page 18: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

DIABETES MELLITUS INDUCED LOC Usually occurs in known DM patient; Either due to a missed meal or poorly

controlled condition.Presentation: Drowsiness, disorientation or

aggressiveness could suggest hypoglycaemia.

There is dry mouth, dry skin and deep breathing in hyperglycaemia.

Page 19: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

MANAGEMENT Give oral glucose if patient is conscious

and I/V if unconscious (irrespective of whether is hypo or hyper) since you may not be able to differentiate.

1mg glucagon can be given in hypoglycaemia.

Page 20: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

ISCHAEMIC HEART DISEASEAngina Pectoris: Presenting with central crushing chest

pain usually precipitated by exertion. No physical sign associated. Relieved by rest and GTN.Myocardial infarction: Ischaemic necrosis of the cardiac musles. Pain more severe than AP and not

relieved by rest or GTN.

Page 21: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

CARDIAC ARREST Characterized by sudden pallor,

respiratory arrest, loss of pulse and LOC.Causes: Myocardial infarction(Asystole and

ventricular fibrillation, analphylaxis)Management: Cardiopulmonary resuscitation.

Page 22: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

CEREBROVASCULAR ACCIDENT (STROKE)

Presentation: Patient is usually a known hypertensive Severity depends on site and size of the

brain involved. Loss of consciousness. Weakness of limbs on one side. Facial dropping Speech affection.Management: Maintain airway and observe.

Page 23: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

FITS/SEIZZURES Known Epileptics Can occur in hypoglycaemia, drug

overdose(LA),may follow LOC. Presentation: LOC with rigid extended body. Jerking movements Incontinence may follow.Management: Most fits terminate spontaneously; just

prevent damage to Patient.

Page 24: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

FITS/SEIZURES 10mg I/V Diazepam can be given if

fitting does not end within 5minutes. Give oxygen. Avoid forcing mental or wooden objects

into patient’s mouth.

Page 25: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

ANAPHYLAXIS Type I hypersensitivity reaction. Usually a reaction to the fixative in local

anaesthetic(LA) called methyl paraben and I/V penicillin.

There could be facial flushing, itching,paraesthesia and peripheral coldness.

Rapid and weak pulse, cold clammy skin. LOC.

Page 26: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

MANAGEMENT Patient is laid flat; administer oxygen. Give I/V 100- 2OOmg hydrocortisone. 10 – 20mg chropheniramine I/V And if need be 1ml of 1:1000 adrenaline

i/m.

Page 27: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

ASTHMATIC ATTACK Usually a known asthmatic.Causes: Anxiety, infection or exposure to

allergens.Presentation: Breathlessness Expiratory wheezes Tachypnoea Use of accessory muscles of respiration

Page 28: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

MANAGEMENT Reassure and give inhaler 0.3cc of 1000 adrenaline may be

required Administer oxygen and I/V

hydrocortisone Avoid barbiturates, NSAID and narcotics

in Asthmatics. May need to see his Physician.

Page 29: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

INHALED FOREIGN BODY Usually a tooth or endodontic instrument Could result in respiratory obstruction,

lung abscess or death. Management: Heimlich manauver(not slapping the

patient on the back. Failing, an endoscopy will be needed. Also X- Ray usually needed for

localisation.

INHALED FOREIGN BODY

Page 31: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

HYPERVENTILATION SYNDROME

Patient is usually an anxious or hysterical woman

Overbreathing until carbon dioxide washes out resulting in tetany and paraesthesia

Palpitations, breathlessness and dizziness often associated.

Causes: Organic cause include pain.

Page 32: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

HYPERVENTILATION SYNDROME

It could be a response to acidosis or poor ventilatory exchange(compensatory physiological response).

Management: Reassurance Re- breathing into a bag to overcome

alkalosis. May require I/V diazepam.

Page 33: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

ADRENAL INSUFFICIENCY

Manifest as inability to cope with stress.

Causes: Include: Addison’s disease, acute

withdrawal of corticosteriods, pituitary or adrenal diseases or damage.

Likely when corticosteroid > 20mg daily for two weeks in the last two years.

Prevention: Preoperative steroids

Page 34: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

ORTHOSTATIC HYPOTENSION

Dizziness in upright position or sudden change in posture.

Causes include anti BP, tricyclics, Narcotics, poor postural reflex, pregnancy.

Management: Prevent by gradual change in position.Treatment: As in vasovagal syncope.

Page 35: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

Note: ONLY FEW EMERGENCIES CAN BE

TREATED DEFINITIVELY IN THE DENTAL SURGERY.

THE IDEA IS TO BE ABLE TO CARRY OUT LIFE SAVING GENERAL MEASURES: ENSURING PATIENT AIRWAY,

BREATHING AND MAINTENANCE OF CIRCULATION.

Page 36: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

TAKE HOME MESSAGE

Anticipation, Prevention and planning. Anticipation: what type of emergency

can you anticipate with this patient? Prevention: what can you do to

decrease the risk of occurrence? Planning: what would you do if the

problem occur?

forcep and open flap to visualise it Swallowed denture will be retrieved

through endoscopy by Otorhinolaryngologist or Cardiothoracic Surgeon after having barium swallow or barium meal radiograph.

Broken filling may occur from improper use of elevator and this have to be replaced

Page 45: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

THOSE ARISING FROM DENTAL TREATMENT: Endodontic emergencies may arise at the

preoperative, intraoperative and postoperative stages of dental care

Preoperative occurs from pulpitis, acute apical periodontitis. RCT will suffice for them except in reversible pulpitis where temporary dressing with dycal and ZOE is necessary

Intraoperative like flare up - do more biomechanical cleaning and dress root canal with non setting Ca(OH)2

Postoperative like high spots - grinding the high spots after detecting with articulating paper.

MANDIBULAR FRACTURE

Page 62: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

THOSE ARISING FROM TRAUMA:Mandibular Fractures Principles and practice of fracture

management as reduce, stabilize and fix, apply here.

For bilateral parasymphyseal mandibular fracture, the lack of tongue support will lead to it falling back and patient suffocating. Emergency measures like applying suture on the tongue and tying it to the patients apron.

THOSE ARISING FROM TRAUMA:Maxillary Fractures: Lefort I, II and III Principles and practice of fracture

management as reduce, stabilize and fix, apply here.

Lefort II fracture will cause backward slide of the segment which will occlude the airway. Emergency measures is to do manual or mechanical reduction.

Page 68: DR O.G. OGBEBOR (BDS,MPH,FMCGDP) NIGER STATE 2012 AGM/CME DECEMBER, 2012.

CONCLUSION Dental emergencies which arises from dental

and medical conditions needs urgent and precise care to prevent complications.

Proper history and clinical examination will help in reducing the prevalence of preventable dental emergencies in the dental clinic.

Training and retraining of dentist will help reduce dental emergencies associated with dental treatment.

Patient education to heighten awareness will help reduce dental emergencies associated with poor dental awareness and personal care.
