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.
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 composite restoration. 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 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
