Information not yet classified
Some editorial classification fields are still pending. The source-reported outcomes and result are shown below; Hydrogenology does not infer a positive or negative signal from prose automatically.
Methods
Human participants studied for oral and dental health; aged 30–50 years. See eligibility criteria in the linked full text.
Human study; the article does not state one consolidated sample total, so no total is inferred.
5 min
Full text reports H₂ dissolved in drinking water. Detected intervention quantities or schedules: 1 ml, 5 min.
H₂ dissolved in drinking water — H₂ only unless the full text explicitly reports oxygen co-delivery.
H₂-related quantities reported in the intervention passages: 1 ml, 5 min. Values are not combined across different experimental arms.
Control or comparison condition reported in the full article; see the linked methods for arm-specific details.
Outcomes and reported result

The complete machine-readable article was checked for source identity, methods, intervention quantities, results, tables, funding and conflict declarations. This public record is based on the full article.
A reported association, difference or mechanism is not automatically a clinical benefit.
