چکیده    The aim of the present study was to compare the corrosion behavior of the ni-cr alloys used for crown and bridge casting in three mouthwashes,in relation to a reference solution,namely fusayama meyer saliva,in order to assess the influence of these products on the corrosion resistance of the ni-cr dental alloys. the three materials analyzed were ni-cr dental alloys: kera nc®,realloy n® and 4 all®,which were tested in three mouthwashes: hexa®,hexadyle® and coxydil® as well as in fusayama-meyer artificial saliva. the corrosion behavior study showed that in hexa® mouthwash the 4 all® alloy was the least resistance to corrosion,in fusayama-meyer artificial saliva tended to be more corrosive for kera nc® alloy,in coxydil® mouthwash exhibited the highest corrosion resistance for kera nc®,and 4 all® alloys,in coxydil® and hexadyle® mouthwashes exhibited the highest corrosion resistance for realloy n® alloy. the results obtained in the present study will enable us to provide attending practitioners with advice concerning mouthwash to recommended,depending on the treatment phase and the alloy used. so we can advise coxydil® mouthwash to patients treated with 4 all® and kera nc® alloys,coxydil® or hexadyle® mouthwashes for the patients treated with realloy n® alloy.
