CHANGES IN RHEOLOGICAL PROPERTIES OF ORAL FLUID IN THE COURSE OF MUCOPROTECTIVE SPRAY APPLICATIONS
Therapeutic personal hygiene products for oral healthcare in the form of sprays for topical applications offer distinct advantages compared to alternative products and they are, therefore, becoming increasingly popular among people now. The goal of the research is to study changes in rheological properties of oral fluid in the course of using mucoprotective sprays with titanium glycerosolvate aquacomplex. The participants of this study were 39 dental student volunteers (the average age of 19±0.75 years) who were divided into three study groups of 13 people each. During two weeks the participants applied oral hygiene products in the form of sprays. The first group applied the spray with titanium glycerosolvate aquacomplex; the second group applied the spray with titanium glycerosolvate aquacomplex and tea tree; the third group applied the spray without titanium glycerosolvate aquacomplex. Changes in rheological properties of oral fluid were measured by the sialometry and viscosity tests. Simultaneously, to carry out organoleptic assessment of sprays, the participants were asked to rate the properties on the ten-point scale. Sialometry results showed diversity during the two-week course of spray applications. After the initial application of Spray 1 saliva flow rates were reliably higher (p≥0.90), (р05; Fig.1.). By the end of the study, though, the flow rates of Spray 2 prevailed ((p≥0.95). Thus, course applications of sprays with titanium glycerosolvate aquacomplex provide a more significant reduction in viscosity of oral fluid. Subject to high organoleptic properties, this can also improve rheological characteristics of oral fluid and reduce the risk of caries in patients.
