Trauma 4 - Long Term Complications of Primary Tooth Trauma Flashcards
Immediate trauma instructions for all injuries
- Soft diet for 10-14 days
- Normal diet just cut everything small and chew with molars - Brush with soft toothbrush after every meal
- Topical chlorrhexidine by parent twice daily for 1 week (on cotton wool rolls for swabbing)
Intrusion requires more frequent review
Enamel dentine fractures tx
Restore with composite or compomer (do not use GI)
Why are endo files avoided for enamel-dentine pulp fractures?
Endo file might encroach upon the follicle thats around the permanent tooth
We want to work 2mm back from the radiographic apex
Tx for an alveolar bone fracture (2)
- Reposition segment
- Splint to adjacent teeth 3-4 weeks
Why would you need localisation of intrusion injury with one film?
To decide whether the root of the tooth has gone into the permanent tooth germ or not
Or gone buccally or labially away from the tooth germ
What 2 types of film would you use to help localise?
PA or lateral pre maxilla
How would you take a localisation of intrusion injury with one PA? (3)
- Take a periapical size film
- If the apical tip appears shorter than the contralateral tooth then it has been displaced towards or through the buccal plate (preferable direction as its away from the developing tooth germ)
- If the apical tip is indistinct and the tooth appears elongated in comparison to the contralateral tooth then the apex is displaced towards the permanent tooth germ
What does a lateral pre maxilla identify?
Direction of displacement as providing a lateral view
How long to wait for an intrusion before consider extracting?
6 months consider extraction to avoid problems in eruption of permanent tooth
Tx for extrusion
Try to reposition maybe but probably just extract
Why do we not replant a primary avulsed tooth?
Possible damage to permanent tooth germ
