ABS TR AC T Objective: To evaluate micro-leakage leakage of indirect resin composite inlay lutedto dentin after specimen's storage in distilled water and lactic acid. Materials and Methods: Standardized MOD Class II cavities were prepared in 48 intact human molars and restored ed with SR Nexco resin composite inlay restorations. The specimens were assigned into three sets (n=16) according to the luting resin cement used; group I: (etch-and--rinse (Variolink N), group II: self-etch (Panavia F2.0) and group III: self-adhesive adhesive (Rely (RelyXUnicem)). Each set was subdivided into two equal subsets (n=8) relative to the storage media either distilled wateror lactic acid. Half of the specimens of each subset were stored in each storage medium for 24h while the other half was stored for 168h (7 days). Results: There was significant difference (p
