What is the epidemiology for dental trauma in children 5 years of age?
- 20 to 30% will suffer dental trauma

What are the different traumatic injuries classifications?
- Concussion
- Subluxation
- Intrusion
- Extrusion
- Lateral luxation
- Avulsion
- Crown fracture
- Crown-root fracture
- Root fracture
- Bone fracture
How do you treat an uncomplicated crown frature (without pulp exposure)?
- NO PROBLEM IF VITAL
- RELAX AND RESTORE
- RECALL AND TEST SENSIBILITY
What are the treatment options for a complicated crown fracture?
- Pulp Cap: Use Bioceramic materials
- Pulpotomy: preferred if open apex
- RCT: preferred if apex closed or post necessary
Crown-root fractures often fracture at an…
angle
How can you see the crown-root fracture line?
Take several angled X-rays varying both vertical & horizontal angulations or CBCT
What is the treatment for a crown-root fracture?
- Anesthetize
- Remove FX element
- Determine Pulpal Exposure & Restorability
—if no exposure – restore
—if exposed VPT or RCT
—if open apex - VPT; RCT if apex closed - Be certain there is NOT a 2nd component of FX
Remember, the __ lesion is not always seen with a cracked root
J
J lesion, if present, does not always mean root is CRACKED/FRACTURED (___%)
28%

posterior
horizontal root fracture
Prognosis with horizontal root fracture depends upon…

What do you do to fix this?
Try to reposition and splint 2-4 wks, check for sensibility after 30 days. Refer to a specialist.
