Аннотация:
The increase of glass ionomer cement operational and technological characteristics to fix non-removable structures plays an important role in orthopedic treatment reliability improvement. The purpose of the study was to perform a comparative evaluation of the film thickness and the fluidity of popular glass ionomer cements: Fuji 1 (GC, Japan), Meron (VOCO, Germany), Polyacrylin (TechnoDent, Russia). The study revealed the dynamics of film thickness change and the fluidity of cements with delayed loading 60, 90, 120, 150, 180 and 210 sec after the commencement of mixing under the powder/liquid ratio recommended by the manufacturers. Throughout the study, the smallest film thickness was demonstrated by the "Polyacrylin" cement and the greatest fluidity was found in the "Fuji 1" cement. © Medwell Journals, 2017.
