Abstract

VARGAS, Carmen F.; KOSS, Myriam A.  and  LOPEZ, Maria E.. Immediate Action of Mouthwashes on Whole Saliva. Int. J. Odontostomat. [online]. 2017, vol.11, n.3, pp.339-346. ISSN 0718-381X.  http://dx.doi.org/10.4067/S0718-381X2017000300339.

Numerous studies confirm the effectiveness of mouthwashes on the viability of microorganisms that produce gingivitis and halitosis, but little is known about their influence on the oral environment. The objective of the following work was to analyze In vivo and In vitro the effect of mouthwashes on total non-stimulated saliva. We worked with saliva from healthy individuals. For In vivo study, samples were collected before and after oral rinsing at different times (1, 5, 10, 15, 30, 45 and 60 minutes). For the In vitro assay, the saliva was incubated with equal volume of the rinse solution at 37 ° C with shaking at different times (1, 5, 10 and 15 minutes). PH was determined immediately collected samples. Subsequently they were centrifuged and determined salivary flow and total proteins. Separation of proteins by SDS-PAGE electrophoresis was performed only in the In vivo assay. The results showed that fluoridated rinses hardly alter oral physiology through salivary flow, pH and total proteins. The combination of sodium fluoride / xylitol produced greater stimulation of salivary flow. The mixture of essential oils caused an increase in salivary flow and pH, reduced the total protein content, evidencing by SDS-PAGE that those involved were particularly those of medium and low molecular weight. Chlorhexidine due to its high substantivity, significantly increased salivary flow and pH In vivo. In vitro, outside the oral environment, the rinses studied had a similar effect on total proteins. Rinses used frequently altered salivary parameters, so that the action they exert on other components of saliva with important biological activity in the oral cavity could be studied.
