ARTIFICIAL SALIVA SUBSTITUTES EVALUATION: THE ROLE OF SOME CHEMICAL-PHYSICAL PROPERTIES

Abstract :

The evaluation of some chemical-physical properties of artificial saliva substitutes easily available on the E.U. market, such as viscosity, pH, buffering capacity, superficial tension, density and spinnbarkeit and compare the results with human natural saliva bibliographic data.

All the saliva substitute products were purchased on the net using University students as customer models. Viscosity and density measurement were performed using a falling ball type viscometer (Anton Paar� - Lovis 200 ME); Surface tension by using a tensiometer (KSV - Sigma 703d), while spinnbarkeit by own instrument built for the purpose. Buffering capacity was determined according to method described in literature.

Viscosity values ranging from a min. value of 1.682 mPa×s to a maximum value of 21.727 mPa×s, CMC based products have the highest viscosity values. Four products (Saliveze^�, Xerotin^�, Saliva Orthana^� and Xerostom^�) have a pH value higher than 6.00. Buffering capacity values ranging from a min. value of 0.909 mmol H⁺/L to 3.333 mmol H⁺/L reveal oad results between the samples.

Form our data and literature review lower values of viscosity and surface tension can be ascribed as the most important features that obtain patient compliance in artificial saliva substitutes. Nevertheless, products selection had to be based on market availability and personal preference.
