Fresh cavities form at the margins of dental amalgam fillings due to microleakage

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that fresh cavities form at the margins of dental amalgam fillings due to microleakage?

Yes. Evidence from multiple histopathological studies confirms that new decay frequently develops along the margins and cavity walls of dental amalgam fillings due to microleakage and plaque accumulation.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked

The analysis

Papers [1], [3], and [4] specifically investigate the histopathology of caries around silver amalgam fillings, demonstrating that cavity wall lesions and demineralization consistently occur at the amalgam-tooth interface (microleakage areas). Therefore, the claim is well supported.
