Effectiveness of three mouthrinses to inhibit acid formation by dental plaque under home-use conditions.

Abstract

A study was conducted to assess the effectiveness of three mouthrinses (Plax, Cepacol and Fluordent) to inhibit acid formation from plaque collected from 21 volunteer dental students. Plaque was collected on each side of the mouth, two hours after breakfast, once-a-week, after a period of 48 hours without any oral hygiene other than the use of the mouthrinses. Initial pH and the change in pH of plaque incubated with sucrose were recorded up to 120 min. Excepting Cepacol for the first week only, no inhibitory effect on acid formation was observed.
