Figure 29: Toward the end of the preparation<br />
sequence, when most of the gross reduction<br />
has been done, I need to be able to visualize<br />
what I am doing at the margin. I turn off the<br />
water to my KaVo ELECTROtorque handpiece<br />
(KaVo <strong>Dental</strong>; Charlotte, N.C.), turn the speed<br />
down to around 3,000 rpm, and slowly take<br />
my 856-025 bur back and forth across the<br />
margin, smoothing it out. With the water off, I<br />
can see everything I am doing, and by turning<br />
the rpm down low, I can keep from overheating<br />
the tooth. Being able to run a handpiece at<br />
low speeds with no water and high torque<br />
is the number one reason I insist on using<br />
electric handpieces.<br />

Figure 30: I notice we still have some decay<br />
on the mesial of tooth #8, so I remove that now<br />
with some Sable Seek ® and Seek ® Caries<br />
Indicator (Ultradent) and a small round bur. I find<br />
it easier to remove any remaining caries at the<br />
end of the preparation sequence rather than at<br />
the beginning, mainly for better access to the<br />
lesion itself, but also because I find I can do a<br />
better job with the bonding steps when I have<br />
better access.<br />

Figure 31: I have intact tooth structure on all<br />
sides of the carious lesion, so I have a high<br />
degree of confidence about the retention of<br />
this small composite filler I am doing to restore<br />
this (Vertise Flow [Kerr Corp.; Orange, Calif.]).<br />
Vertise Flow is a self-etching flowable composite<br />
that is perfect for small situations like this.<br />
Because it is a self-etching product, there is no<br />
separate etch and bond step. Vertise Flow also<br />
works very well for small Class I restorations,<br />
sealants, preventive resin restorations and quick<br />
little build-ups like this one.<br />
