| ABSTRACTBack ground: Dental impressions must be considered the potential to transmit the serious diseases to all dentalpersonal who routinely handle them; it is therefore recommended to disinfect dental impressions for all patients.Materials and methods: Five alginate impressions were made of bronze model with a complex surface of smallpyramids and flat surface in the middle part using perforated acrylic resin trays. These impressions were treatedseparately with selected disinfecting agent [ Hexyl tiethyl ammonium chloride salt, Tetra butyl ammonium iodide salt,Iodophor, Ethanol and 2-propanol]. Dimensional accuracy, surface detail reproduction, setting time wasinvestigated after disinfection of alginate. The data was analyzed by a computerized statistical program.Results: The results showed that the dimensional change was statistically in significant for most of the dimensions at 5percent level except some measurement show slight significant difference related to dimensional accuracy.Regarding reproduction of surface details, the results showed insignificant difference of the mean scores ofexperimental groups among the three evaluators. It was found that treating the alginate with the selecteddisinfecting agents will accelerate the setting time of the material.Conclusion: The testing disinfecting agents can be used safely regarding dimensional accuracy and surface detailreproduction, although setting time will be influenced compared to control alginate.Key words: Alginate, disinfection, dimensional changes, surface detail, setting time.
