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. Soltaire–2, 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
