artificial saliva sorption for three different types of Dental composite resin An in vitro study
Abstract
Aims: To evaluate the artificial saliva sorption for three different types of light
activated composite resin. Materials and Method: A total of thirty six specimens (bars)
(3x8x15)mm were prepared from three different types of light activated composite
resin. (Tetric N-ceram, Iv o clar-vivadent-Liechtenstein. Arabesk voco Germany.
Soltaire2, Heraeus, kulzer, Germany). Twelve specimens were prepared from each
type of composite resin. Complete fabrication of composite resin specimens, polished
and kept in three different types of artificial saliva medium, three specimens from
each type of composite resin as interactive specimens kept in type of artificial saliva
and the last three specimens kept in Deionized water as control medium. The weight of
each specimens was measured at an analytic balance before and after different time
intervals of storage (1,2,7,21,35,60) days to measure the amount of absorption of
artificial Saliva (gaining and loss of weight). The study showed a significant difference
(P< 0.05) in artificial saliva sorption among the three different types of composite
resin at different time intervals when kept in different artificial saliva medium. Tetric
N-ceram (nano composite) has more affect with three different types of artificial saliva
medium (gaining and loss weight) followed by Arabesk, Soltaire-2 composite resin for
different types of artificial saliva at different time intervals. Conclusion: Dental
composites are sensitive to artificial salive medium (gain and loss of weight) Tetric N
ceram (nano composite) interact actively followed by Arabesk and Soltaire-2 for
three different artificial saliva medium at different time intervals.
