IADT Guidelines Flashcards
What guidelines are to be used for dental trauma?
IADT 2012
(International association of dental traumatology)
What is prevalence of dental trauma?
25% of children
33% of adults
What is the most common traumatic injury to the primary dentition?
Luxation injuries.
What is the most common traumatic injury to the permanent dentition?
Crown fractures.
What are some consequences of primary trauma on developing permanent dentition?
Tooth malformation (dilaceration)
Impacted teeth
Eruption disturbances
What general advice can be given to a patient after they sustain a TDI?
Care for optimal healing
Avoid contact sports
Good OH
Rinsing with antibacterial agent (CHX)
Describe this TDI.
Infraction of an incisor.
Incomplete fracture of the enamel, without loss of tooth structure. Likely to be asymptomatic unless a luxation injury is involved.
What is the management for this TDI?
Infraction of an incisor.
In cases of marked infractions, etching and sealing with resin to prevent discoloration.
No review necessary.
Describe this TDI.
Note: No dentine has been exposed.
Enamel fracture of the 12.
What symptoms/features would you expect from this TDI?
Note: Dentine not exposed. No associated luxation injury.
No TTP
Normal mobility
Positive response to pulp tesing
What would your managment be for this TDI?
Note: Dentine not exposed, no sign of luxation injury.
Locate tooth fragment
Radiograph to rule out root fracture
If fragment available bond to tooth.
Conventional restoraiton if not present.
Review 6-8wks, 1yr.
Describe this TDI.
Note: Dentine exposed, but pulp sound.
Enamel-dentine fracture.
Fracture confined to enamel and dentine, pulp not exposed.
What is TDIs typically reslt in TTP?
Luxation, concusson, and root fracture.
What would you rmanagment be for this enamel dentine fracture?
Locate tooth fragment
Bond fragment to tooth if available
Cover exposed dentine with GI or composite
If dentine is pink, then place CaOH liner (indicates its within 0.5mm of pulp.
Review 6-8wks, 1yr
Describe this TDI.
Enamel-dentine-pulp fracture (complicated)
Clear exposure of pulp, which will be sensitive to stimuli.
What would your managment of this TDI be?
Note: Tooth is not TTP.
Complicated EDP fracture.
Generally advantagous to preserve pulp in young patient.
Pulp cap, or partial pulpotomy if open apex.
Conventional RCT if mature apex.
Conventional restorative treatment or bond fragment.
Review: 6-8wks, 1yr
Describe this TDI.
Note: Coronal fragment is mobile but there is no pulpal exposure?
Uncomplicated root-crown fracture.
Fracture involving enamel, dentine, and cementum.
Would be TTP
Sensibility test positive for apical fragment.
Confirm with radiograph.
What would your managment be for this TDI?
Note: Coronal piece mobile, no pulpal exposure.
Uncomplicated crown root fracture.
Tooth can be stabilised to adjacent teeth, if in an emergency situaton and treatment plan uncertain. Tx options:
- Fragment removal and gingivectomy
- Orthodontic extrusion for crown placement
- Surgical extrusion for crown placement
- Extraction followed by prosthesis
Note: All fractures with severe apical extensions will require extraction. Vertical fractures almost always do.
Review: 6-8wks, 1yr
What radiographs can be used to investigate potential root fractures?
Periapical
Occlusal variatons
What would your managment of this TDI be?
Note: Radiographic evidence of pulpal exposure, coronal fragment mobile.
Complicated crown-root fracture.
Tooth can be stabilised to adjacent teeth, if in an emergency situaton and treatment plan uncertain. Tx options:
- Appropriate pulp therapy for tooth development
- Fragment removal and gingivectomy
- Orthodontic extrusion for crown placement
- Surgical extrusion for crown placement
- Extraction followed by prosthesis
Note: All fractures with severe apical extensions will require extraction. Vertical fractures almost always do.
Review: 6-8wks, 1yr
Why is pulpotomy prefered for developing teeth?
Preserve vitality, to enable apexification
This creates a more durable root and an apex that is easier to seel during obturation.
What are the clinical signs of root fracture?
Coronal segment may be mobile
Tooth may be TPP
May bleed from gingival sulcus
Negative sensitivity testing
Transient crown discolouration may occur
What are the radiographic signs of root fracture?
Fracture involving root of tooth in horizontal/oblique plane.
Can use differing oblique views to visualise horizontal fractures.
Apical third more commonly oblique.
Mid-coronal third more commonly horizontal.
What is the management for root fracture?
Reposition if displaced
Check position radiographically
Stabilise with flexible splint
Monitor healing up to a year
If pulp necrosis develops, carry out RCT of coronal fragment
What are the reveiew appointments for a root fracture?
4ks (remove splint)
6-8wks
16wks
6mths
1yr
Yearly for 5 yrs
How long should a root fracture be splinted for?
4 weeks
Consider longer if root fracture near cervical area (up to 4 months)
