Subtraction spectra (differences in the reflectance by the UV-
componentoftheillumination:fluorescenceinthereflectance
mode) of BUT based resin composite are presented in
Fig. 1
,
and those after thermocycling are presented in
Fig. 2
. The val-
ues for the fluorescent peak height and fluorescent area of
BUT based resin composites before and after thermocycling
are listed in
Table 1
. In the control group (no FWA), fluorescent
peak was not detected. The concentration of FWA influenced
the fluorescent peak height significantly (
p
<0.05), but thermo-
cycling up to 1000 cycles did not influence the value (
p
=0.902),
and there was no significant interaction between two independent variables based on two-way ANOVA. Fisher’s PLSD
interval by the concentration was 0.5. The concentration of

Subtraction spectra of varied resin matrices-based resin
composites are presented in

. The values for the fluo-
rescent peak height and fluorescent area are listed in
Table 2
.
Fluorescent peak wavelengths in BT and UT based resin com-
posites were similar to those of BUT based resin composites.
Peak height was influenced by the type of resin matrix and
concentration of FWA, and there was significant interaction
between two variables based on two-way ANOVA. Fisher’s
PLSA interval by the resin matrix was 0.9. Fluorescent area
