CDH 4.5 Flashcards
What is the diagnosis of external inflammatory resorption?
Root surface intact but tramlines of root canal are distinct
What is the treatment of external inflammatory resorption?
Endo
If progressive conducer iodoform paste (vitapex) or CaOH every 6 months and plan for prosthetic
What is the diagnosis of internal inflammatory resorption?
Tramlines of root canal indistinct, root surfaces intact, radiolucency in pulp chamber, pink ‘cervical’ discolouration
What is replacement resorption (ankylosis)?
Initiated by severe PDL damage
Where bone directly fuses to dentine
What is the management of lateral luxation and extrusion?
Reposition under LA as very mobile
Flexible splint for 4 weeks
What are the current strategies for treatment for intrusion with closed apices?
0-3mm = allow spontaneous re-eruption, no movement after 3 weeks do ortho traction 3-7mm = disimpact and reposition with ortho and flexible splint for 2 weeks >7mm = disimpact and surgically reposition and flexible splint for 2 weeks
What are the current strategies for treatment for intrusion with open apices?
<7mm = allow for spontaneous re-eruption >7mm = disimpact and move ortho or surgically reposition and flexible splint for 2-4 weeks
What does MTA stand for?
Mineral Trioxide Aggregate
What advice would you give to a patient ringing about an avulsed tooth and why?
Hold tooth by crown
Rinse under saline or milk - not water as can cause PDL cells to lyse
Do not rub root
Replant, bite on tissue and go straight to dentist
If can’t be replanted - store in saliva/ saline/ milk/ tooth rescue box
How long can PDL cells survive outside of the mouth and in what environment?
Can survive 2-6hrs in pH 6.5-7.2
What milk is best to store an avulsed tooth in?
Chilled fresh low fat milk
What is the likely scenario of when the PDL cells are most likely to be viable?
Replanted immediately/ in 15 mins
What is the likely scenario of when the PDL cells are most likely to be viable but compromised?
Tooth in storage medium and extra oral dry time <60mins
What is the likely scenario of when the PDL cells are most likely to be compromised?
Total extraoral dry time >60mins
What is the managed treatment of an avulsed tooth with closed apices within 2 weeks after injury?
