When people used the special mouthwash, their blood pressure went up within one day and stayed higher for the whole week they used it.

Scientific Claim

In healthy young adults, the blood pressure increase from disrupting oral nitrate-reducing bacteria occurred within 1 day of mouthwash use and was sustained throughout the 7-day intervention period.

Original Statement

“The blood pressure effect appeared within 1 day of disruption of the oral microflora and was sustained during the 7-day mouthwash intervention.”

Appropriate Language Strength

association

Can only show association/correlation

Assessment Explanation

The study design supports describing the temporal pattern of blood pressure changes following mouthwash use. The language 'occurred' and 'was sustained' appropriately reflects the observed pattern without implying causation.

More Accurate Statement

“In healthy young adults, the blood pressure increase following disruption of oral nitrate-reducing bacteria was observed within 1 day of mouthwash use and persisted throughout the 7-day intervention period.”

Similar Assertions

The blood pressure increase from using the special mouthwash was the same whether measured at the doctor's office, at home, or with a 24-hour monitor.

90%

When people start using mouthwash that kills mouth bacteria, their blood pressure can go up within just one day.

89%

When mouth bacteria are disrupted, blood pressure goes up regardless of how it's measured - whether at the doctor's office, at home, or with a 24-hour monitor.

89%

Even when people ate a diet low in nitrate, using the special mouthwash still increased their blood pressure, which suggests the effect comes from the body's own nitrate recycling process.

86%

The blood pressure increase from using the special mouthwash happened both during the day and at night, with the diastolic pressure going up more during the day.
