| Summary: | Purpose: This research examines the release of mercury from dental amalgam restorations over time, analyzing the relationship between the number of restored surfaces and mercury levels in artificial saliva. Materials and Methods: An in vitro study was performed utilizing 224 plastic model teeth restored with dental amalgam. The teeth were categorized based on the number of surfaces restored, which ranged from Group 1 (1 surface) to Group 6 (48 surfaces). These were then immersed in artificial saliva, and the mercury levels were measured at intervals up to 30 days using atomic absorption spectrophotometry. Results: The release of mercury increased in correlation with both the number of restored surfaces and the passage of time. Significant differences were noted among the groups, with the highest release occurring in the group with the greatest number of surfaces. Mercury levels exhibited a consistent rise from baseline to day 30. Conclusions: The amount of mercury released from amalgam restorations increases in relation to both the number of restored surfaces and the duration of exposure. |
