Teaching Module & Competency: Primary Tooth TraumaPrepared by :Cynthia Christensen; DDS, MSKarin Weber-Gasparoni; DDS, MS, PhDUniversity of Iowa2008
Objectives
Understand the incidence of primary tooth trauma
Understand how to triage primary tooth trauma
Understand clinical presentation of the most common types of primary tooth trauma and treatment options
Epidemiology of Tooth Trauma
30% of children suffer trauma to primary dentition.
Most injuries to primary teeth occur at 18-30 mo of age:
“…more traumatic dental injuries occur to younger
children, probably because the children are gaining
mobility and independence, yet lack full coordination
and judgment.”
Garcia-Godoy et al.
Clinical Examination
Intra/ extra oral soft tissues
Swelling Fractured, luxated, or
missing teeth Pulp exposures Occlusion Deviation on opening
TRIAGE: Occlusion Indicates Fractured Alveolus or Mandible
Immediate referral to Oral Surgeon or ER Advise patient to be kept NPO
Radiographic Exam
For young children, parent or dental staff must hold
Establish Baseline
Detect root or alveolar injuries or pathosis
What about Sutures?
Extraoral: Plastic/ENT surgeon best for esthetic outcome
Introral: Small laceration = No
sutures. Larger lacerations =
General Dentist or Oral Surgeon
Possibility: Foreign Body in Lip or Tongue
Checking for Tooth Fragment
Palpate puncture/laceration
Soft tissue radiograph
¼ the exposure time of nearest teeth
Common Injuries
Treatment Options
Concussion / Subluxation
Concussion: injury to the tooth and ligament without displacement or mobility
Subluxation: tooth is mobile, but is not displaced
Concussion and Subluxation Management
Periapical radiograph OTC pain meds prn Soft diet for 1 week Advise parent of possible
sequelae Follow-up, 2-4 weeks
Concussion/Subluxation
Neurovascular bundle at apex may be crushed or severed
PDL may be torn
Prognosis for Recovery = Good
Discoloration of Primary Tooth Post Trauma Color may change 2-4 weeks
after trauma
May retain/regain vitality and
return to near normal color
within 6 months
Monitor. Esthetics may be a
concern if color does not
resolve
Color may be pink, purple, grey or brown
Pulpal Obliteration/Calcific Metamorphosis
History of Trauma Tooth darker-usually
yellowish Radiograph shows pulpal
space narrowing or obliterated
NO TX-observe for normal exfolitation
All Teeth Do Not Recover: Abscess 6 Months Post Concussion
Note associated soft tissue swelling
Confirm Dx and check root structure with periapical radiograph
Radiographic Abscess #F
Note: #E resorption post trauma. No Tx #F extraction indicated
Tooth causing occlusalinterference
Follow up in 2 weeks: Advise parents of possible injury / damage to permanent teeth

LATERAL LUXATION / EXTRUSION INJURIES: RECOMMENDATIONS
**All treatment is ideal and assumes patient has manageable behavior.
Recommendations also assumeappropriate radiographic survey.
(Reference: AAPD Handbook of Dentistry)
Extract and advise parents of potential damage to permanent tooth
Tooth is aspirationrisk
Allow for spontaneousre-positioning or
re-position and splint orconsider extraction
Extrusion and Luxation With Occlusal Interference
Extraction is recommended
most of the time due to risk
of aspiration of mobile teeth
and damage to permanent
tooth bud
**Key = Degree of Severity
and cooperation
Extrusion and Luxation With Occlusal Interference
Primary Teeth Reposition
and Splinting RARE unless..
Excellent Patient Cooperation
Excellent Recall Compliance
Pulp Exposed
Dentin Exposed
Rough Edge Present
Smooth edge and if required
restore with composite
Clinical and radiographic follow up. Advise parents of
possible injury to permanent teeth and monitor forsigns of pathology
Composite or GIprovisional restoration
“band-aid” if symptomatic

Treatment Planning Crown Fracture Injuries
All treatment is ideal and assumes patient has manageable behavior.
Recommendations also assume appropriate pre-operative radiographs
