Another instrument frequently used with etching
and bonding procedures associated with composite
resins is a disposable brush with a reusable handle. An
example is shown in figure 4-12. Single-use disposal
brushes are being used more frequently, aiding in good
infection control practices.
CEMENT AND INSULATING BASE
The instruments in this group are used for mixing
and handling restorative resin, and various temporary
restorative, insulating, and pulp-capping materials.
Three different spatulas are available for mixing
restorative materials, as shown in figure 4-13. Some of
these spatulas can cause discoloration in the material
being mixed. The selection of a mixing spatula is not
critical except when preparing a permanent anterior
Some composite restoration
material discolors easily, so use the spatulas provided
by the manufacturer when working with it. The single-
ended #322 and #324 are suitable for mixing other
materials other than composites. A smaller version for
the #324 is the #313 spatula. The #313 is used for
mixing small quantities of cement.
Insulating Base Instruments
Insulating base instruments have a small metal ball
at the working end and are often referred to as calcium
hydroxide instruments. They are used to mix, carry,
and place insulating bases, and are available as a
