    X-ray micro-analysis revealed phosphorus (P) and tin (Sn) in the marginal seal material of aged, amalgam-restored teeth. Other elements like calcium (Ca) and copper (Cu) were also detected in varying amounts.

    Area of Science:

    • Dental Materials Science
    • Analytical Chemistry
    • Materials Science

    Background:

    • Amalgam restorations are common in posterior teeth.
    • Understanding the marginal seal is crucial for restoration longevity.
    • Fractured teeth provide unique interfaces for material analysis.

    Purpose of the Study:

    • To determine the elemental composition of marginal seal material in fractured amalgam-restored teeth.
    • To identify key elements present at the amalgam-tooth interface.
    • To investigate the chemical nature of the marginal seal.

    Main Methods:

    • X-ray micro-analysis was employed to examine elemental composition.
    • Ten fractured, aged, amalgam-restored posterior teeth were analyzed.
    • Replicas were used to isolate and collect marginal seal material for analysis.

    Main Results:

    • Phosphorus (P) and tin (Sn) were consistently detected in all analyzed marginal seal samples.
    • Calcium (Ca), chlorine (Cl), copper (Cu), iron (Fe), sulfur (S), and zinc (Zn) were found in varying proportions across specimens.
    • Elemental composition varied among different marginal seal samples.

    Conclusions:

    • The marginal seal material in aged amalgam restorations contains specific elements like P and Sn.
    • The presence of various elements suggests complex interactions at the amalgam-tooth interface.
    • Further research can explore the role of these elements in seal integrity and longevity.
