Amalgam dowel core
An amalgam dowel core, also termed a Nayyar core (after the clinician
who first reported the technique), is a method described for restora-
tion of endodontically treated molars before provision of an indirect
restoration such as a crown
34
. This direct core utilises the coronal pulp
space and a few millimetres of the radicular canal for retention. This
corono-radicular core (Nayyar core) is described fully in Chapter 4.
