Evaluation of saliva and tongue coat pH before and after use of mouthwashes

Abstract

The aim of this work was to evaluate saliva and tongue coat pH in oral healthy patients with morning breath through an analog pHmeter and color pH indicators, before and immediately after use of different mouthwashes and 30 minutes after rinsing, relating the possible pH alterations to parameters of halitosis. 50 patients were allocated in 5 groups, with 5 different solutions rinses – Cetilpiridine chloride associated with sodium chloride, Triclosan, enzymatic solution, essential oil and distilled water. Triclosan and essential oil increased saliva pH immediately after rinsing and enzymatic solution reduced saliva and tongue coat pH.
