What does IADT stand for?
International Association of Dental Traumatology (IADT)
Trauma: Relevant non-dental injuries to be aware of?
Head injuries
Overdose
Facial fractures
Facial lacerations
Why should splints be flexible and how is this achieved?
To avoid undue stress, and allow for functional tooth movement.
Wire of <0.4mm is used to achieve this.
Trauma sequelae: Yellow/brown
Pulpal obliteration (reparative dentine shining through)
X-ray shows pulpal narrowing
Associated w luxations
Sensibility test;
Vital = manage aesthetics
Non-vital = RCT
—> specialist referral
Trauma sequelae: Grey
Blood products from pulpal haemorrhage
Associated w luxations, avulsions, complicated crown fracture
Non-vital = RCT and aesthetics
…or XLA
Trauma sequelae: Pink area
Shine through of invading tissue, usually from external cervical root resorption (ECRR)
Soon = tooth revascularisation ?Monitor, frequently review, should reverse.
Later = suspect ECRR
Refer to specialist.
Root resorption types: Internal inflammatory resorption
Inflammation within the pulp is breaking down the dentine in the pulp.
How would you manage this sequelae?
This is internal inflammatory root resorption.
RCT and aesthetic management.
If root has perforated, bioactive root filling material may be used (MTA & Biodentine).
Root resorption types: Internal replacement resorption
internal inflammatory resorption —> get replaced with bone.
shows clinically and x-ray as IIR.
Root resorption types: External inflammatory resorption (EIR)
Damage to PDL and root surface stimulates this in trauma.
Vital tooth = reparative process and is self-limiting
Similar symptoms to periapical periodontitis.
X-ray notice root canal is still visible = EXTERNAL resorption process.
Root resorption types: External cervical resorption (ECR)
Osteoclastic cells from the adjacent periodontium are thought to invade the exposed root surface, via gaps in the cementum, and form a fibrovascular lesion (resorption phase), which may ultimately become calcified and develop into a fibro-osseous tissue (reparative phase).
Root resorption types: External surface resorption (ESR)
his is a non-infective, transient, pressure-induced resorption. This resorptive process will stop progressing once the source of the pressure has been removed, resulting in repair of the resorbed root-face with cementum.
Root resorption types: Transient apical breakdown
A non-infected transient resorption of the apical portion of the root and the adjacent bone.
Widening of the apical PDL = resolves within a year.
This phenomenon is essentially an external inflammatory resorption (EIR) with a short resorption phase followed by repair.
What are key features of a splint following trauma?
Passive, flexible and conform to the arch.
0.4mm stainless steel wire
Pulpal canal obliteration (PCO) occurs more frequently in teeth with…
open apices, and is indicative of viable tissue within the root canal.
Tx of fully developed teeth (mature teeth with closed apex) that have been intruded/extruded/laterally luxated. OR fractures (involving the root)
Treat endodontically EARLY.
Calcium hydroxide placed 1-2 weeks after trauma for up to 1 month —> then RC filling.
This is to avoid external inflammatory resorption (associated w infection).
Tx of incomplete developed teeth (immature teeth with open apex) that have been intruded/extruded/laterally luxated. OR fractures involving the root
Regular check ups —> pulp could revascularise!
Weigh this up with the chance of inflammatory root resorption (this will be rapid).
Combined injuries of poorer prognosis may be considered for earlier RCT.
Enamel-dentin fracture with pulp exposure
Complicated crown fracture
—> partial 2-3mm
—> coronal (whole coronal portion, reaching level of orifices)
—> extirpation (pulpEctomy)
Place non-setting calcium hydroxide cement.
Pulp capping
APEXOGENESIS
Vital pulp therapy
within 24 hours of the incident!
If over 24 hours then pulp is likely contaminated and pulpotomy is opted for.

Non-vital immature permanent tooth tx
Mineral trioxide aggregate (MTA) plug of ~4-5mm then normal GP on top.
Sets in the presence of moisture.
Neglect
the persistent failure to meet a child’s basic physical and/or psychological needs, likely to result in the serious impairment of the child’s health or development.
Safeguarding vs child protection
Safeguarding = preventative approach to child protection
Child protection = reactive approach to suspected or known cases of abuse or neglect
What percentage of child victims of physical abuse show signs in the head and neck region?
60%
Key areas of non-accidental injuries occurring
