TOLENTINO, Elen de Souza; CHINELLATO, Luiz Eduardo Montenegro  and  TARZIA, Olinda. Saliva and tongue coating pH before and after use of mouthwashes and relationship with parameters of halitosis. J. Appl. Oral Sci. [online]. 2011, vol.19, n.2, pp. 90-94. ISSN 1678-7757.

OBJECTIVES: The aim of this work was to evaluate saliva and tongue coating pH in oral healthy patients with morning bad breath before and after use of different oral mouthrinses. MATERIAL AND METHODS: Saliva and tongue coating pH of 50 patients allocated in 5 groups were measured respectively by a digital pHmeter and color pH indicators, before, immediately after and 30 min after rinsing 5 different mouthrinses: cetilpiridine chloride associated with sodium chloride, triclosan, enzymatic solution, essential oil and distilled water. RESULTS: Only triclosan and essential oil increased salivary pH immediately after rising. The enzymatic solution decreased salivary and tongue coating pH immediately after rinsing. CONCLUSIONS: Salivary pH tended to be acidic while tongue coating pH tended to be alkaline, even after rising. Triclosan and essential oil mouthrinses increased salivary pH immediately after rinsing. Enzymatic solution decreased saliva and tongue coating pH immediately after rising.
