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

Is it true that modern toothbrush features remove more plaque than regular toothbrushes?

Yes. Multiple clinical trials and design studies demonstrate that modern toothbrush features, such as electric power, ionic technology, photocatalytic elements, and optimized manual bristles, remove significantly more dental plaque than standard manual toothbrushes.

Verdict: SUPPORTED · 7 sources for, 1 against · Last checked

The analysis

The retrieved literature strongly supports the claim that modern toothbrush features (such as ionic power, acoustic/electric action, specialized bristle designs, photocatalytic elements, and visualization tech) improve plaque removal over standard traditional brushes. While one smaller study found non-significant differences in orthodontic patients, the overwhelming majority of clinical trials and robot test studies demonstrate statistically significant improvements, leading to a 'SUPPORTED' verdict.
