A comparative study between the atomic absorption and spectrophotometric method in the assessment of the corrosion


journal of kerbala university, Volume 7, Issue 2, Pages 21-25

Back ground: Atomic absorption method is the most accurate method in the assessment for the determination of corrosion of dental alloy. The spectrophotometric method with the use of chromogenic complex was used also in the assessment of the corrosion. The aim of this study was to compare between the two methods.
Material and Methods: twenty amalgam specimens were used: each was stored in 5 ml of normal saline solution for 1 month. The specimens were randomly grouped into two groups (group A and group B). Then the assessment of the corrosion was done by measuring of the released mercury, for group A is done by the atomic absorption method and for group B by the spectrophotometric method.
Result: there is no statistical significant difference between two methods.
Conclusion: the spectrophotometric method was successful alternative method to the atomic absorption methods in the assessment of the corrosion.
