According to the manufacturer,
the anodized aluminum metal handpiece distributes
LED heat and prevents scratches, discoloration,
and damage from accidental falls. The handpiece
comes in 4 color options: silver, pink, blue, and gold.
Output Power
The output power provided by the Fusion curing
light is 1500 mW/cm2. When the 8 dentists who participated
in this evaluation were asked about the
importance of output power when purchasing a curing
light, 7 said it is very important and 1 said it is
important. The evaluators were then asked to rate
the output power of the Fusion curing light. Seven
evaluators rated it as excellent and 1 rated it as good.
One evaluator called the output power “Fantastic.”
Another evaluator said, “1500 mW/cm2 is great!”
Ease of Use
When asked about ease of use, the evaluators
focused on the position and feel of the
on/off switch. One evaluator rated the
ease of use of the Fusion curing light as
excellent, 3 rated it as very good, 2
rated it as good, and 2 rated it as fair.
Virtually all of the evaluators said that
they would like to see a change in the
design of the on/off switch. One evaluator
said, “The activation button should be
raised. It is difficult to find by touch and
the operator has to look [away from the
patient] to find the button, which distracts
[them] from where they are placing
the light.” Another evaluator said, “I’d
prefer a raised dot on the ‘go’ button.” A
third evaluator said, “The only issue is
that the trigger for turning the light on or
off needs tactile definition.”
Curing Time
According to DentLight, the Fusion
curing light cures all materials (bonding
agents and adhesives, bases, liners,
sealants, and lab materials) in less than 5
seconds for 2 mm A3 or lighter and 3
seconds for metal bracket bonding. The
evaluators were asked to rate the curing
time of the Fusion light. Six rated it as
excellent, 1 rated it as very good, and 1
rated it as good. One evaluator described
the curing time as “Fantastic.”
Size and Weight
The Fusion curing light is described
by the manufacturer as having a sleek,
anodized aluminum body that weighs
only 110 grams. When the evaluators
were asked to rate the size of the light, 7
rated it as excellent and 1 rated it as very
good. With regard to weight, 6 rated the
light as excellent and 2 rated it as very
good. One evaluator described the size
of the light as “Perfect. Very sleek, small,
and easy to handle.” Another evaluator
said the light is “very compact.” A third
evaluator said that the light’s “portability
is great.”
Overall Satisfaction
When the evaluators were asked if
they would recommend the Fusion curing
light to their colleagues, 7 said definitely
or probably. Five evaluators said
they definitely or probably would purchase
the light in the future.
At the end of the evaluation, the dentists
who participated were asked for
their overall satisfaction rating for the
Fusion curing light. Three rated it as
excellent, 4 rated it as very good, and 1
rated it as fair. One evaluator said that
the Fusion curing light is “easier to manage
than [another light].”
