Trauma Long Term Complications Flashcards
What are common sequelae of primary tooth trauma?
Discolouration
Discolouration and infection
Delayed exfoliation
Describe asymptomatic discolouration of teeth
Asymptomatic, can be vital or non-vital
Mild grey - immediate discolouration may maintain vitality
Opaque/yellow - pulp obliteration
If no signs of pulp necrosis or infection, then observe and review
Describe discolouration and infection
Symptomatic - non-vital
Sinus, gingival swelling and abscess may be present
Increased mobility
Radiographically evidence of periapical pathology may be evident
Extract or endodontic tx
Describe delayed exfoliation
Consequence of developing occlusion
Retained primary teeth can cause ectopic eruption of permanent successor, or can delay or prevent eruption
How does age of primary teeth trauma relate to injury of permanent teeth?
They younger the primary trauma, the more likely the permanent tooth will be injured
What damage to primary teeth, affects the permanent successor most?
Intrusion
Where primary trauma has occurred, what percentage of permanent teeth have enamel defects?
44%
What is enamel hypomineralisation?
Qualitative defect of enamel - normal thickness but poorly mineralised
White/yellow defect
What are the tx options for enamel defects?
No treatment
Composite masking and localised removal
Tooth whitening
What is enamel hypoplasia?
Quantitative defect of enamel - reduced thickness but normal mineralisation
Yellow/brown defects
What are the treatment options for enamel hypoplasia?
No tx
Composite maksing
What is dilaceration?
Abrupt deviation of the long axis of the crown or root portion of the tooth
What are the management options for crown dilaceration?
Surgical exposure and orthodontic realignment
Improve aesthetics restoratively
What are the management options for root dilaceration?
Combined surgical and orthodontic approach
When is delayed eruption common?
Premature loss of a primary tooth can result in delayed eruption of around 1 year due to thickened mucosa
