| Summary: | Introduction: Scientifically and clinically there has been lot of
development in the field of aesthetic dentistry. However, there
is limited or restricted information regarding the color stability of
flowable composite materials.
Aim: The aim of this study was to evaluate the spectrophotometric
color stability of three different flowable composite materials
with respect to three different pH of saliva.
Materials and Methods: The study included 90 different
samples. Thirty samples in each composite group; (Group A:
G-aenial universal flo; Group B: Z 350 XT flowable; Group C:
Esthet x flow). All samples from each group were immersed
in distilled water for 24 hours. Total color difference (∆E) was
recorded for each sample. After this 10 samples from each group
were respectively immersed in 6.5, 7 and 7.5 pH of artificial
saliva. All samples were kept in dark room for seven days and
then ∆E for each sample was recorded and was compared to
previous recorded ∆E for the same sample.
Results: Maximum color change was seen irrespective of
material in 6.5 pH of saliva. G-aenial universal flo showed least
change irrespective of pH of saliva.
Conclusion: Thus, the present study reveals that acidic pH
level affects the coloration of composite resins by affecting the
surface integrity and as reported in previous studies, various
coloring agents in beverages and other dietary components
assists the process due to absorption of these coloring
substances into the resin matrix. |
