The objective of this study was to investigate the effects of aging in distilled water or Saliva onmicrostructure, molecular structure, roughness and mechanical properties of Filtek and Silorane compositematerial. Ion released from Filtek and Silorane was measured. Candida Spp is adhered on the Filtek surface but Candida Spp and Aspergillus Sp is adhered on Silorane surface when aged in Saliva.Microstructure, molecular structure, hardness, bending strength, roughness and elasticmodulus values of Filtek and Silorane composite material are changed as a result of stored in distilled water or Saliva 30 days.
