INTRODUCTION
Emergency: Any urgent condition perceived by the
patient as requiring immediate medical or surgical
evaluation or treatment.
A sudden, urgent, usually unforeseen occurrence
requiring immediate attention.
28-1-10 3
Dental emergency :
An acute condition affecting the teeth, such as
inflammation of the soft tissues surrounding teeth or
past treatment complications of dental surgery
Endodontic emergency:
Defined as an unscheduled visit associated with pain
or swelling from pulpoperiapical pathoses requiring
immediate diagnosis and treatment
28-1-10 4
 1/3rd of all dental emergencies are from endodontic
origin
 90% of emergencies with pain as symptom, the pain
is pulpal or periapical
 In every year a number of on working days and
school days are lost due to dental pain in the world.
28-1-10 5
DIFFERENCE
Emergency
A condition requiring
an unscheduled office
visit with diagnosis and
treatment to be done
immediately , here the
visit cannot be
rescheduled because of
the severity of the
problem.
Urgency
Indicates a less severe
problem; a visit may be
scheduled for mutual
convenience of the
patient and the dentist

Diagnosis
Definitive treatment
Drugs
Diagnostic sequence
 Obtain information about the patient’s medical and dental
histories.
 Ask pointed subjective questions about the patient’s pain:
history, location, severity, duration, character, eliciting
stimuli.
 Perform extraoral examination
 Perform intraoral examination
 Perform pulp testing procedures.
 Use palpation and percussion sensitivity tests to determine
periapical status
 Proper Interpretation of radiographs
 Rapid and accurate diagnosis are important in the treatment of
endodontic emergencies
28-1-10 11
• SIGN - An objective evidence of a disease, such
evidence as is perceptable to the examining
physycian.
• SYMPTOM – It is a subjective , not usually visible to
others, symptoms are the patients experiences about
the illness, disease, or injury.
28-1-10 12
Most of the times patient
comes with chief
Complaint of
 Pain,
 Swelling,
 Transient loss of function.
 Esthetic abnormalities.
28-1-10 13
ACUTE PULPITIS
Acute reversible pulpitis:
 It is a mild to moderate inflammatory condition of the
pulp caused by noxious stimuli in which the pulp is
capable of returning to the uninflammed state
following removal of the stimuli
28-1-10 14
SYMPTOMS
 Short duration pain
 Does not linger
 Non tender to percussion
 Might be difficult to localize
 Might give an exaggerated response to vitality tests
 No radiographic significance.
28-1-10 15
CAUSES
 Caries close to the pulp
 Premature contact
 Recurrent caries
 Occlusal trauma
 Thermal Shock
 Microleakage
 Galvanic shock
 Chemical irritation - sweet or sour food
28-1-10 16
Choice of Treatment (Grossman)
The best treatment is prevention,
Protective base under restorations.
Avoid marginal leakage.
Occlusal reduction.
Avoid excessive heat during cavity preperation
Palliative treatment
Zinc oxide eugenol interim restoration
If pain disappears – restoration
If not - Pulp extirpation.
28-1-10 17
ACUTE IRREVERSIBLE
PULPITIS
 It is the persistent inflammatory condition of the
pulp, caused by a noxious stimuli
 Abnormal sensation to cold
 Abnormal sensation to hot
28-1-10 18
28-1-10 19
SYMPTOMS
 There is often a history of spontaneous bouts of pain which
may last from a few seconds up to several hours
 When hot or cold fluids are applied, the pain elicited will be
more significant; cold may relieve the pain
 Pain may radiate initially, but once the periodontal ligament has
become involved the patient will be able to locate the tooth
 The tooth becomes tender to percussion once inflammation has
spread to the periodontal ligament
 A widened periodontal ligament may be seen on the
radiographs in the later stages
Causes
 Bacterial involvement of pulp through caries.
 Other factors-chemical, thermal, mechanical, or
galvanic irritation
 Reversible pulpitis may deteriorate in to irreversible
pulptis
28-1-10 20
Treatment
 Anesthetize the affected tooth.
 Apply rubber dam.
 Prepare access cavity.
 Remove the pulp from the chamber
 Locate the root canal orifice.
 Extirpate the pulp by sequentially. Instrumenting
with reamer or files or broaches to within 1mm
short of apex
28-1-10 21
 Irrigate with sterile saline solution, NaOCl solution.
 Dry the root canal with sterile absorbent points.
 Insert a medicated cotton pellet moistened with an
obtudant.
 Place a temp filling .
 Relieve the occlusal trauma.
 Analgesic if required
28-1-10 22
28-1-10 23
PULPOTOMY
Conditions where pulpectomy is not possible in
multirooted teeth
 Anesthetize the affected tooth.
 Apply rubber dam.
 Prepare access cavity.
 Remove the pulp from the pulp chamber with
spoon excavator or round bur
 Cotton pellet moistened with formocresol is
placed in the cavity and it is sealed with
ZnOE
28-1-10 24
ACUTE ALVEOLOR ABSCESS
Localized collection of pus in the alveolar bone at the
root apex of the tooth following death of pulp with
extension of infection through the apical foramen into
the periapical tissue.
CAUSES
 Bacterial involvement
 H/0 of trauma
 Mechanical or chemical irritation
 Pulpitis or pulpal necrosis.
 Exacerbation of chronic periapical lesion.
 Endodontic-periodontic lesion ,deep pocket.
 In severe conditions this odontogenic
infection can spread into the adjacent
soft tissues and leads to life threatening
complication called as cellulitis.
 Bacteria mainly involving the acute cellulitis are
staphylococcus group
 They produce hyluronidase, fibrolysin, collagenase
that breakdown the intercellular cementing substance.
 This allows infection to spread rapidly
into the facial spaces and cause life
threatening situation
28-1-10 25
28-1-10 26
• Simultanious bilateral spread of infection into
submandibular, sublingual and submental space s is
called as ludwigs angina.
PHLEGMON:
 A massive cellulitis that does not go to suppuration
proceeds towards fast inflammatory infiltration of
subcutaneous tissue.
 Skin is bluish in color because of
tissue cyanosis
 Streptococcus haemolyticus
28-1-10 27
SYMPTOMS
Local reactions:
 Tenderness of tooth
 Severe throbbing pain
 Swelling
 Sinus tract
SYSTEMIC REACTIONS:
 Elevated temperature
 GI disturbances
 Malaise
 nausea
 Dizziness
 Lack of sleep
28-1-10 28
DIAGONSIS
 Pain and presence of swelling
 Mobility of tooth
 Non responsiveness to pulp testing
 Sensitiveness to percussion
 Small or large or diffuse radiolucency in radiographs
28-1-10 29
TREATMENT
 Local anesthesia
 Isolation
 Access cavity
 If drainage does not occur, apical foramen is
enlarged to 25, 30 no size to obtain the drainage. –
apical trephination .(weine)
 If time permits, complete cleaning and shaping of
the canals .
 Irrigation with NaOCl.
 Closed dressing given with ZnOE/ Placement of
intracanal medication
 Adjustment of occlusion
 If systemic involvement is present prescribing the
antibiotics and analgesics.
28-1-10 30
Apical trephination
BRITISH DENTAL JOURNAL VOL 198 NO. 12 JUNE 25 2005
• Incisional drainage is the first principle in
management of acute dentoalveolar infection.
• Penicillin-resistant bacteria are often present in acute
dental infection.
• The presence of penicillin resistant bacteria does not
adversely affect the outcome of treatment even if
penicillin is prescribed.
• It is likely that antibiotic therapy is often prescribed
unnecessarily in treatment of acute dental infection

TRAUMATIC AND
EASTHETIC EMERGENCIES
Traumatic injury to a tooth can cause
 1 cracked crown
 2. fracture crown
 3. fracture root
It can be broadly classified as
 1. Crown fracture
 2. Root fracture
28-1-10 32
CRACKED TOOTH
SYNDROME
 Incomplete fracture of a vital posterior tooth that involves the
dentin and occasionally extends into the pulp
 A fracture plane of unknown depth and direction passing
through tooth structure that if not already involving, may
progress to communicate with the pulp and
or periodontal ligament
 30-50 years of age.
 Mandibular 2nd molars > Mandibular 1st
molars > Maxillary premolars
 Men = Women
28-1-10 33
Two classic patterns of crack formation
1. Crack is centrally located and following the dentinal
tubules may extend to the pulp
2. Crack is more peripherally directed
and may result in cuspal fracture
28-1-10 34
Symptoms:
 Sensitive to hot and cold
 Pain upon biting and rapidly ceases after
relieving the pressure
Diagnosis:
 Thorough dental history.
 History of trauma,
 Clenching or bruxism and chewing habits.
28-1-10 35
 Examine the teeth with an explorer
 Check hot and cold sensitivity tests. If a sharp pain is
felt with temperature, and the pain rapidly diminishes
with removal of the stimulus, - fracture is more likely
present.
 Probe the gum tissue for pockets
 Check for a cracked filling, removal of filling help
to visualize the crack
28-1-10 36
1. Transillumination method
3. Use of dyes

28-1-10 48
MANAGEMENT (WEINE)
Part I (emergency treatment at the site of injury)
 Cleaning the tooth under the running water
 Reinsertion of tooth into the socket and
attain firm pressure .
 If reinsertion not possible place the tooth
in the transport media
28-1-10 49
Part II (emergency treatment at the dental office ):
 Place the tooth in the saline
 Health history, examination of area, radiographs
 Wiping the gross debris from the root surface with
wet sponge
 Irrigate the socket with saline
 Reimplant the tooth
 Check the position with radiographs
 Splint with arch wire and composite
28-1-10 50
Part III (completion of endodontic treatment)
 Closed apex - One week after replantation RCT is
adviced
 Open apex – watched with out pulp extirpation
 Stabilization period – 1 week
 Post operative instructions
 Soft diet
 Antibiotics and analgesics for 1-4 days
Use of emdogain is controversial
JCDA January 2000, Vol. 66, No. 1
28-1-10 51
TRANSPORT MEDIA

the injury and
reimplantation
 Fracture of alveolus
 Blood clot in socket
 Direct mud at site
Follow up
 1w, 1m, 3m, 6m, 12m,
and annually for 5yrs
28-1-10 54
Fate of Reimplanted Tooth
 Tooth may maintain vitality
 Periodontally sound tooth may result
 Possible external resorption
 Ankylosis
 If no endodontic treatment is done –internal
resorption
28-1-10 55
ROOT FRACTURE
 Ellis class VI
 873.63
Can be divided into
 Vertical &
 Horizontal
1. Coronal
2. Middle
3. Apical third
28-1-10 56
On the basis of level of root fracture in
relation to various horizontal plane of
periodontium
• Class 1:fracture line nearing the
gingival attachment.
• Class 2: fracture line extends below
the level of the attached gingiva but
not below the alveolar crest
• Class 3: fracture line with in the
coronal one third of the root, but
below the level of alveolar crest
• Class 4: when fracture line extends
below the level of the alveolar crest,
but with in middle third of the root
• Class 5: when fracture line is in the
apical third of the root
28-1-10 57
HORIZONTAL ROOT
FRACTURES
Diagnosis:
 Patients history
 Visual examination
 Radiographs
 Pulp vitality tests
Prognosis:
 Location of the fracture
 Root development
 Direction of fracture
 Displacement of fractured segment
28-1-10 58
28-1-10 59
Sequelae to root fractures (Andreasen)
 Healing with calcified tissues.
 Healing with interproximal connective tissue.
 Healing with interproximal bone.
 Healing with granulation tissue.
Treatment
Non surgical
 No mobilty – no treatment
 Mobile coronal fragment – repositioning
stabilization (4-6weeks)
 Nonseparated segments: Root canal therapy for both the
segments and stabilization with interradicular splints
 Separated segments: RCT for coronal segment only (apical
segment with vital tissue) . (cohen& burns)
28-1-10 60
28-1-10 61
Surgical treatment (weine)
Apical 1/3rd fractures: rct of coronal segment only, apical
segment is left, it may heal, resorb in most instance does
not cause any problem.
Middle 1/3rd fractures: placement of cr-co pin joining
coronal and apical segment.
VERTICAL ROOT FRACTURE
Etiology:
1. Physical traumatic injuries
2. Occlusal prematurities
3. Para functional habits
4. Resorption
5. Iatrogenic factors
Placement of posts
Forceful insertion of large sized files into
the canal, Vertical condensation

Hemisection:
 Multirooted teeth with fracture confined to one root
only
 Multirooted teeth with fracture confined to furcation
only
LUXATION
 Abnormal mobility of the tooth with in the socket
with or without displacement as a result of trauma or
injury
Five types of luxation injuries (Andreasen)
 Concussion
 Subluxation
 Extrusive luxation
 Lateral luxation
 Intrusive luxation
28-1-10 67
28-1-10 68
 Concussion : injury to supporting structures without
abnormal loosing or displacement
Subluxation: injury with abnormal
loosing
Extrusive luxation: partial displacment
of the tooth out of its socket
Lateral luxation: eccentric displacement
with fracture of alveolar socket
Intrusive luxation: displacement of
tooth deeper into the alveolar socket
Intrusion
28-1-10 69
Subluxation
Extrusive luxation
Lateral luxation
Intrusive luxation
TREATMENT
 Concussion: requires only
relieving pressure by selective
grinding
 Subluxation: occlusal relief
and splinting for 7-12 days
 Extrusive luxation: reposition
and splinting it for 2-3 weeks
28-1-10 70
28-1-10 71
 Lateral luxation: reposition and splinting it for
15 days
 Intrusive luxation:
1. repositioning immediately
2. wait and see with the hope that the tooth will re erupt
on its own
EMERGENCIES WHEN THE
PATIENT IS UNDER
TREATMENT (FLARE UP)
Etiological factors
 High filling
 Micro leakage
 Micro exposure of pulp
 Thermal or mechanical injury during cavity
preparation or an inadequate lining under metallic

1. Grade A – NSAIDS – preoperatively.
2. Grade B – Antibiotics – not recommended.
3. – NSAIDS used as a solution.
4. Grade C - Corticosteroids have a weak
5. evidence in pain management.
28-1-10 76
RECRUDESCENCE OF A
CHRONIC APICAL ABSCESS
 Phoenix abscess
 Chronic lesion become acute after
the first endodontic treatment.
Mechanism:
 Recrudescence = breaking out
 Facultative anaerobes multiply
rapidly after canal is opened by endodontic therapy
 Canal instrumentation reduces some strains and some
virulant bacteria will grow rapidly
28-1-10 77
28-1-10 78
Symptoms:
Mobility, tenderness to percussion and swelling
Treatment :
Incision and drainage through the root canal
Initial exudation: irrigation with warm saline
If drainage shows resistance- leave the tooth open
Closed dressing – 2-5 days later
If drainage is stopped –closed dressing
HYPOCLORITE ACCIDENT
 Expelling of NaOCl beyond
the apex
 This is due to locking the
needle of the irrigating
syringe in the canal and
forceful injecting the
irrigant
Symptoms :
 Sudden extreme pain with
in mins after the irrigation
 Swelling with in minutes
 Profused prolonged
bleeding.

IEJ Vol 42 2009
1EJ Vol 39 2008
28-1-10 81
IEJ, vol 41, 2008
TREATMENT
 Allow the bleeding to
continue ,
 Antibiotics, analgesics
for five and three days
respectively .
 Prescribing anti
histamines (since it
should be considered as
hypersensitive reaction)
28-1-10 82
ASPIRATION OR INGESTION
 A serious problem, life threatening event.
 Operator is responsible
Recognition:
 Sudden disappearance of slipped instrument
 Sudden violent gagging or spasmodic coughing ,
wheezing, decrease breathing sounds by the patient .
 Radiographic evidence of presence of file in the
alimentary tract or airway
28-1-10
83
TREATMENT
Radiographic examination
• To know nature and size of the foreign body.
• Antero-posterior chest radiograph.
• Lateral chest radiograph.
• Lateral neck radiograph
• Supine abdominal radiograph.
28-1-10 84
The draw back with these radiographs is limitation for
radio opaque objects, in this scenario the following
are considered.
• Gastroscopy.
• Bronchoscopy.
• Computed tommography.
• Monitoring of physical signs.
• Test of stool for occult blood.
28-1-10 85
 If the instrument is in pharyngeal pouch and
oesophagus try to locate and remove with blunt long
tweezer
 Instrument is in lungs – surgical intervention.
 Bronchus – causing problem – remove it surgically .
 If it is in the alimentary tract monitor
radiographically and physical signs.
 Advice the patient to take fibre diet so that it provides
better movement.
 Usually it passes in faeces, if not remove surgically.
Prevention of these accidents is done by the universal
use of rubber dam and using a dental floss tied to the
instrument.

PREVENTION OF FLARE UPS
 Proper diagnosis
 Determination of correct working length
 Radiographs
 Apex locaters
 Complete extirpation of pulp
 Proper Irrigation
 Aviod filling too close to radiographic apex
28-1-10 88
28-1-10 89
 Perform apical trephination only if necessary
 Reduce the tooth from occlusion if apex is severely
violated by over instrumentation
 Placement of intracanal medicament
 Prescription of mild analgesics and antibiotics whenever
condition warrants it
POST ENDODONTIC
TREATMENT
 High restoration
 Overfilling
 Underfilling
 Root fracture

  • 2.  Introduction  Definition  Difference between emergency and urgency  Diagnosis and management  Classification  Acute pulpitis  Acute alveolar abscess  Esthetic emergencies  Emergencies during the treatment  Post endodontic treatment emergencies  Conclusion  References 28-1-10 2
  • 3. INTRODUCTION Emergency: Any urgent condition perceived by the patient as requiring immediate medical or surgical evaluation or treatment. A sudden, urgent, usually unforeseen occurrence requiring immediate attention. 28-1-10 3
  • 4. Dental emergency : An acute condition affecting the teeth, such as inflammation of the soft tissues surrounding teeth or past treatment complications of dental surgery Endodontic emergency: Defined as an unscheduled visit associated with pain or swelling from pulpoperiapical pathoses requiring immediate diagnosis and treatment 28-1-10 4
  • 5.  1/3rd of all dental emergencies are from endodontic origin  90% of emergencies with pain as symptom, the pain is pulpal or periapical  In every year a number of on working days and school days are lost due to dental pain in the world. 28-1-10 5
  • 6. DIFFERENCE Emergency A condition requiring an unscheduled office visit with diagnosis and treatment to be done immediately , here the visit cannot be rescheduled because of the severity of the problem. Urgency Indicates a less severe problem; a visit may be scheduled for mutual convenience of the patient and the dentist 28-1-10 6
  • 7. CLASSIFICATION According to WALTON & TORABINEJAD 1.Pre treatment emergencies 2.Interappointment emergencies 3.Post treatment emergencies 28-1-10 7
  • 8. According to Grossman 1.Acute conditions a. Reversible pulpitis b. Irreversible pulpitis c. Alveolar abscess d. Periodontal abscess 2. Emergencies during treatment 3. Fractures I. Crown II. Root 4.Avulsed tooth 5.Reffered pain 28-1-10 8
  • 9. Before treatment 1. Pulpal pain 2.Acute periapical abscess 3.Cracked tooth syndrome During treatment 1. Recent restorative treatment 2. Periodontal treatment 3. Exposure of pulp 4. Fracture of root or crown 5. Pain as a result of instrumentation a. Acute apical periodontitis b. Phoenix abscess 28-1-10 9 BDJ: Vol 197 no 6 sep 2004; 299-305
  • 10. 3 D’s of successful management Diagnosis Definitive treatment Drugs
  • 11. Diagnostic sequence  Obtain information about the patient’s medical and dental histories.  Ask pointed subjective questions about the patient’s pain: history, location, severity, duration, character, eliciting stimuli.  Perform extraoral examination  Perform intraoral examination  Perform pulp testing procedures.  Use palpation and percussion sensitivity tests to determine periapical status  Proper Interpretation of radiographs  Rapid and accurate diagnosis are important in the treatment of endodontic emergencies 28-1-10 11
  • 12. • SIGN - An objective evidence of a disease, such evidence as is perceptable to the examining physycian. • SYMPTOM – It is a subjective , not usually visible to others, symptoms are the patients experiences about the illness, disease, or injury. 28-1-10 12
  • 13. Most of the times patient comes with chief Complaint of  Pain,  Swelling,  Transient loss of function.  Esthetic abnormalities. 28-1-10 13
  • 14. ACUTE PULPITIS Acute reversible pulpitis:  It is a mild to moderate inflammatory condition of the pulp caused by noxious stimuli in which the pulp is capable of returning to the uninflammed state following removal of the stimuli 28-1-10 14
  • 15. SYMPTOMS  Short duration pain  Does not linger  Non tender to percussion  Might be difficult to localize  Might give an exaggerated response to vitality tests  No radiographic significance. 28-1-10 15
  • 16. CAUSES  Caries close to the pulp  Premature contact  Recurrent caries  Occlusal trauma  Thermal Shock  Microleakage  Galvanic shock  Chemical irritation - sweet or sour food 28-1-10 16
  • 17. Choice of Treatment (Grossman) The best treatment is prevention, Protective base under restorations. Avoid marginal leakage. Occlusal reduction. Avoid excessive heat during cavity preperation Palliative treatment Zinc oxide eugenol interim restoration If pain disappears – restoration If not - Pulp extirpation. 28-1-10 17
  • 18. ACUTE IRREVERSIBLE PULPITIS  It is the persistent inflammatory condition of the pulp, caused by a noxious stimuli  Abnormal sensation to cold  Abnormal sensation to hot 28-1-10 18
  • 19. 28-1-10 19 SYMPTOMS  There is often a history of spontaneous bouts of pain which may last from a few seconds up to several hours  When hot or cold fluids are applied, the pain elicited will be more significant; cold may relieve the pain  Pain may radiate initially, but once the periodontal ligament has become involved the patient will be able to locate the tooth  The tooth becomes tender to percussion once inflammation has spread to the periodontal ligament  A widened periodontal ligament may be seen on the radiographs in the later stages
  • 20. Causes  Bacterial involvement of pulp through caries.  Other factors-chemical, thermal, mechanical, or galvanic irritation  Reversible pulpitis may deteriorate in to irreversible pulptis 28-1-10 20
  • 21. Treatment  Anesthetize the affected tooth.  Apply rubber dam.  Prepare access cavity.  Remove the pulp from the chamber  Locate the root canal orifice.  Extirpate the pulp by sequentially. Instrumenting with reamer or files or broaches to within 1mm short of apex 28-1-10 21
  • 22.  Irrigate with sterile saline solution, NaOCl solution.  Dry the root canal with sterile absorbent points.  Insert a medicated cotton pellet moistened with an obtudant.  Place a temp filling .  Relieve the occlusal trauma.  Analgesic if required 28-1-10 22
  • 23. 28-1-10 23 PULPOTOMY Conditions where pulpectomy is not possible in multirooted teeth  Anesthetize the affected tooth.  Apply rubber dam.  Prepare access cavity.  Remove the pulp from the pulp chamber with spoon excavator or round bur  Cotton pellet moistened with formocresol is placed in the cavity and it is sealed with ZnOE
  • 24. 28-1-10 24 ACUTE ALVEOLOR ABSCESS Localized collection of pus in the alveolar bone at the root apex of the tooth following death of pulp with extension of infection through the apical foramen into the periapical tissue. CAUSES  Bacterial involvement  H/0 of trauma  Mechanical or chemical irritation  Pulpitis or pulpal necrosis.  Exacerbation of chronic periapical lesion.  Endodontic-periodontic lesion ,deep pocket.
  • 25.  In severe conditions this odontogenic infection can spread into the adjacent soft tissues and leads to life threatening complication called as cellulitis.  Bacteria mainly involving the acute cellulitis are staphylococcus group  They produce hyluronidase, fibrolysin, collagenase that breakdown the intercellular cementing substance.  This allows infection to spread rapidly into the facial spaces and cause life threatening situation 28-1-10 25
  • 26. 28-1-10 26 • Simultanious bilateral spread of infection into submandibular, sublingual and submental space s is called as ludwigs angina.
  • 27. PHLEGMON:  A massive cellulitis that does not go to suppuration proceeds towards fast inflammatory infiltration of subcutaneous tissue.  Skin is bluish in color because of tissue cyanosis  Streptococcus haemolyticus 28-1-10 27
  • 28. SYMPTOMS Local reactions:  Tenderness of tooth  Severe throbbing pain  Swelling  Sinus tract SYSTEMIC REACTIONS:  Elevated temperature  GI disturbances  Malaise  nausea  Dizziness  Lack of sleep 28-1-10 28
  • 29. DIAGONSIS  Pain and presence of swelling  Mobility of tooth  Non responsiveness to pulp testing  Sensitiveness to percussion  Small or large or diffuse radiolucency in radiographs 28-1-10 29
  • 30. TREATMENT  Local anesthesia  Isolation  Access cavity  If drainage does not occur, apical foramen is enlarged to 25, 30 no size to obtain the drainage. – apical trephination .(weine)  If time permits, complete cleaning and shaping of the canals .  Irrigation with NaOCl.  Closed dressing given with ZnOE/ Placement of intracanal medication  Adjustment of occlusion  If systemic involvement is present prescribing the antibiotics and analgesics. 28-1-10 30 Apical trephination
  • 31. BRITISH DENTAL JOURNAL VOL 198 NO. 12 JUNE 25 2005 • Incisional drainage is the first principle in management of acute dentoalveolar infection. • Penicillin-resistant bacteria are often present in acute dental infection. • The presence of penicillin resistant bacteria does not adversely affect the outcome of treatment even if penicillin is prescribed. • It is likely that antibiotic therapy is often prescribed unnecessarily in treatment of acute dental infection 28-1-10 31
  • 32. TRAUMATIC AND EASTHETIC EMERGENCIES Traumatic injury to a tooth can cause  1 cracked crown  2. fracture crown  3. fracture root It can be broadly classified as  1. Crown fracture  2. Root fracture 28-1-10 32
  • 33. CRACKED TOOTH SYNDROME  Incomplete fracture of a vital posterior tooth that involves the dentin and occasionally extends into the pulp  A fracture plane of unknown depth and direction passing through tooth structure that if not already involving, may progress to communicate with the pulp and or periodontal ligament  30-50 years of age.  Mandibular 2nd molars > Mandibular 1st molars > Maxillary premolars  Men = Women 28-1-10 33
  • 34. Two classic patterns of crack formation 1. Crack is centrally located and following the dentinal tubules may extend to the pulp 2. Crack is more peripherally directed and may result in cuspal fracture 28-1-10 34
  • 35. Symptoms:  Sensitive to hot and cold  Pain upon biting and rapidly ceases after relieving the pressure Diagnosis:  Thorough dental history.  History of trauma,  Clenching or bruxism and chewing habits. 28-1-10 35
  • 36.  Examine the teeth with an explorer  Check hot and cold sensitivity tests. If a sharp pain is felt with temperature, and the pain rapidly diminishes with removal of the stimulus, - fracture is more likely present.  Probe the gum tissue for pockets  Check for a cracked filling, removal of filling help to visualize the crack 28-1-10 36
  • 37. 1. Transillumination method 3. Use of dyes 28-1-10 37 2. Tooth Slooth technique
  • 38. 28-1-10 38 ASSESSMENT OF TOOTH LARGE CRACK WITHOUT PULP INVOLVEMENT WITH PULP INVOLVEMENT SMALL CRACK RESTORE WITH COMPOSITE •STABILIZE THE TOOTH. •OCCLUSAL ADJUSTMENTS, •PERMANENT STABILIZATION, •BONDED OR CAST RESTORATION STABILIZE THE TOOTH , EXTIRPATE THE PULP, ENDODONTIC THERAPY, CAST RESTORATION VERTICAL FRACTURES WITH HOPELESS PROGNOSIS SHOULD BE EXTRACTED Treatment Dental traumatology 2006
  • 39. TOOTH FRACTURE  Most common cause is trauma,  More common in children Fracture of tooth or teeth mainly depends on the  Energy of Impact  Mass and velocity of object  Resilience of the object  Shape of the object  Angle of direction 28-1-10 39
