what is the main aim of inter-visit dressing
to ensure and maintain a bacteriostatic/ cidial environment in the root-canal between RCT appointments
other objectives of inter-visit dressing
following disinfection, viable bacteria can still be isolated from approximately __% of root canals
50%
what intervisit dressing is commonly used
non-setting calcium hydroxide
outline calcium hydroxide
what is the commercial name for setting calcium hydroxide
Dycal
how long does it take for the hydroxyl ions in calcium hydroxide to diffuse through dentine
21 days (reaches a maximum pH of 9 here)
how long should calcium hydroxide be left in the root canal
optimally, between 2-4 weeks and no longer as its efficacy decreases rapidly afterwards
(disposable)
how is calcium hydroxide placed in the root canal(s)
a large K file/ straight probe carries the paste into the coronal 2/3 of the canal
a small K file e.g. size 10 or 15 to reach the apex
what should be placed on top of the calcium hydroxide
why does a material need to be placed on top of calcium hydroxide
to prevent the calcium hydroxide washing out
paste material that is rolled into a bead and placed in cavity over the calcium hydroxide
what material is an alternative to Cavit/ Coltosol
why is placing cotton wool in the access cavity not a good idea
what goes on top of the sponge/ Cavit/ Coltosol
what is the aim of a GIC restoration
outline the type of GIC used
note about GIC
what must you ensure when placing calcium hydroxide in the root canals
ensure calcium hydroxide does not touch the walls of the access cavity as this will compromise the bonding of GIC
what should happen at the appt. after placing the intervisit dressing
all the hard material in the access cavity should be removed before disturbing the Cavit
then wash out the Cavit and calcium hydroxide with a blunt needle/ K file and sodium hypochlorite
what is the collective term for Ledermix, Odontopaste and calcium hydroxide
medicaments
outline Odontopaste
outline Ledermix
outline DFUs
what are common post-op complications of RCTs
pain
swelling
loss of intervisit restoration
outline post-operative instructions
