| Summary: | Background: Resin composite has many benefits, namely good mechanical
properties, fast polimerization, aesthetical quality, easy to handle, and its ability
to adhere on the surface of the enamel. However, there are also some
disadvantages from this material, one of them is the existance of residual
monomers. Bulk fill composite is available in the forms of sculptable (hard) and
flowable (liquid). Most of the matrix of the resins is diacrylate (aromatic or
aliphatic). Bis-gma, udma and tegdma are the matrix monomers which are
commonly used. The residual monomers of tegdma, bis-gma and udma show high
level of cytoxicity. Furthermore, they also have poor mechanical properties such
as wear resistance, hardness and tendency to change color and may cause pulp
reactions. Based on the background above, the authors wanted to analyze some
residual monomers which can be extracted by bulk fill composite with a thickness
of 4 mm and diameter of 5 mm in the soaking of 10 minutes, an hour and 24
hours. Purpose: To investigate the different amount of residual monomers in bulk
fill sculptable and flowable composites in the soaking of ethanol 75% (10 minutes,
an hour and 24 hours). Methods: Sculptable and flowable composites were used
in this study, samples (4 mm thick, 5 mm diameter) were prepared and
polymerized for 10 seconds with an intensity of 1025 mW / cm2 of light emitted
diode (LED). After the sample was made, each sample was immediately immersed
in a 75% ethanol solution which was used as an extraction liquid and stored in
amber colored bottles at room temperature. Samples were taken as many as 7 cc
at intervals of 10 minutes, an hour and 24 hours. Samples were analyzed by
HPLC. The data obtained were analyzed using Kruskal-Wallis Test, Independent
T Test and Mann-Whiteney Test at a significance level of p <0.05. Result: The
amount of elusion remaining monomers of bulk fill flowable composite was
higher than bulk fill sculptable monomer. Udma composite of bulk fill flowable
soaked in 75% ethanol solution for 24 hours was the highest among other
monomers. Conclusion: Residual monomers eluted inside bulk fill composite
resins in all time periods and the amount of eluted monomers increases with time. |
