Trauma Flashcards
Signs of intracranial Pressure
Loss of consciousness Nausea and vomiting Dizziness Headache Lethargy or irritability Memory loss Pupil size and reaction to light
Occlusal view for primary teeth
Occlusal plane
Gentle bite to stabilize
Outside edge should be at incisors
60 degrees through bridge of nose
2 week radiographic evidence
Pulpal necrosis
3 week radiographic
Inflammatory resorption
6 week radiographic
Replacement resoprtion ankylosis
Short term reaction of teeth to trauma
Pulpal hyperemia (pulpitis) Internal hemorrhage
Long term reactions of teeth to trauma
Pulpal necrosis
Pulp canal obliteration
Inflammatory resorption
Replacement resorption
Pulpitis internal hemorrhage
May lead to cold sensitivity
This is an immediate response
May be transient q
Pulp canal obliteration and pulpal necrosis
These are long term responses
Both ar irreversible
PCO causes yellow discoloration
Replacement resoprtion
Direct union of bone and root
Resorption of root and replacement with bone
Direct results of loss of vital PDL
Lack of mobility and dull percussion sound
2 types of injuries
Injuries to the tooth =fractures
Injuries to the PDL=luxation
Goals of fracture
Temp cover up
Establish follow up plan
Goals of luxation
Resportion and stabilize
Establish follow up plan
Class I fracture
Limited to enamel
Restore perm with composite
Ignore primary
Class II fracture
Fracture includes enamel and dentin
Pulp is not exposed
Class II primary tooth
Composite/GI
Then monitor for symptoms
Definitively restore with composite/GI
3-4 week follow up
Class II fractures Permanent Teeth
Bond fragment if available
Composite blind aid
6-8 weeks clinical and radiographic exam
Class III Fractgure
Involves enamel and dentin and pulp is exposed
Class III fractures primary teeth options
Partial pulpotomy
Pulpotomy
Pulpectomy
Extraction
Class III primary teeth usually comes down to
Behavior
Partial pulpotomy
Extraction
Class III primary teeth follow up
1 week clinical exam
6-8 weeks clinical radiographic exam
1 year clinical and radiographic exam
Class III fractures permanent young tooth
Young tooth with open apex or closed apex
Direct pulp cap Partial pulpotomy (Cvek technique)
Class III fractures permanent mature tooth
Mature tooth with closed apex
Pulpectomy
Direct pulp and partial are also options
Cvek Partial pulpotomy
Single tooth isolation
Access the pulp chamber to a depth of 1-2 mm
Extend to allow access keep in dentin
Bleeding is good
Medicaments
Condense a sufficient thickness of dry calcium hydroxide powder to fill preparation at least 1 mm in depth
If no bleeding
Tooth may be necrotic and pulpectomy is indicated
Class III fractures permanent teeth
Restoration can occur after success of Cvek has been determined
Typically after 6-8 weeks follow up
Strip crown or composite buildup
Chin trauma
Posterior crown fracture
Mandibular consular fractures
Cervical spine injury
