Question · asked by 1 review
Grape seed extract (GSE) and its proanthocyanidin fractions vs Untreated or vehicle control (some studies vs positive antimicrobial controls, e.g. chlorhexidine/fluoride): Cell death / cytotoxicity
- Population
- Streptococcus mutans (in vitro cultures and biofilms)
- Intervention
- Grape seed extract (GSE) and its proanthocyanidin fractions
- Comparison
- Untreated or vehicle control (some studies vs positive antimicrobial controls, e.g. chlorhexidine/fluoride)
- Outcome
- Cell death / cytotoxicity
One study reported minimal cytotoxicity (<1% cell damage) with grape seed extract (ungraded).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
