   Abstract:	Objectives: The purpose of this study was to examine the effects of the water movement across dentin bonded to conventional glass-ionomer cements. Material and method: Class V cavities were prepared on extracted permanent third molar teeth, filled with conventional glass-ionomer cement Fuji IX and stored in artificial saliva for one and 18 months. After the storage time interval, the teeth were sectioned longitudinally and examined by SEM (in secondary and backscattered electron mode) and EDAX. Results: Spherical structures were noted in the material adjacent to the interface with the hard dental substances after 18 months. The air voids found next to the interface between the traditional glass-ionomer cements and dentin are mainly “egg-shell-like” (although, solid ones were also found). They are probably a result of the continuation of the setting reaction in the air voids of the original polyalkenoate matrix, which appears because of water diffusion from the humid dentin. The EDAX analysis proved that these formations consist of high quantity of strontium, silica and aluminium. Conclusions: The described spherical formations may lead to improvement of the compressive strength, which is found in old restorations with conventional glass-ionomer cements.
