working ends and come in single- and double-ended
types. Some of the more commonly used burnishers
are shown in figure 4-9.
COMPOSITE RESIN INSTRUMENTS
A variety of double-ended instruments make up
this instrument group. They are used to transport and
place dental cements, resins, temporaries, and
insulating and pulp-capping materials. The working
ends on composite resin instruments range from
varying small cylinders to assorted angled, paddle-like
shapes. Figure 4-10 illustrates the Woodson #3, #W3,
and #11 (also know as Stellite), which are some of the
commonly used instruments in this category.
Other types of composite resin instruments are
made of plastic. Plastic instruments can be heat
sterilized and used on composites and cements. They
either come included in the kit of resin material from
the manufacturer or, in some cases, can be ordered as a
set as shown in figure 4-11. Some advantages to using
plastic instruments are that they won't discolor or
contaminate the composite restoration, and composite
resin material will not cling to the instrument.
