Abstract
Aims: This study was performed to evaluate the effect of
Pepsi, orange juice and coffee as storage media on the Degree
of Conversion (DC) of three types of composite resin.
Materials and Methods: Three types of visible light-curing
composite restorative material (Te-Econom, Tetric ceram
and VOCO) were used in this study, The specimen disks of
composites were prepared using Polyethylene mold 5mm in
diameter and 1mm in height, The degree of conversion was
measured for each group after storage for 7days in light-proof
boxes containing storage media, The degree of conversion of
the samples was measured by Fourier transform infrared
spectroscopy (FTIR), One way analysis of variance and
paired differences tests were used for statistical analysis.
Results: The results revealed that there was a significant
difference in the degree of conversion of the three types of
composite resins when stored in all type of storage media as
compared to dry samples(control group). Conclusions:The
degree of conversion of the three types of composite resin
was increased when stored in different storage media.
Key words: Storage Media, degree of Conversion, composite
Resin.
