Acidic saliva substitutes

Comparison of Artificial Saliva Substitutes

Human saliva consists of water, glycoproteins, enzymes, antimicrobial substances and electrolytes. From biophysical point of view, saliva is a viscoelastic fluid with distinct surface activity. Commercial artificial saliva used in salivary gland disorders should resemble normal saliva in biophysical properties. In this study we evaluated the biophysical properties of saliva and existing saliva ...

The effect of saliva substitutes on enamel erosion in vitro.

OBJECTIVES To investigate the effect of saliva substitutes on enamel erosion in vitro. METHODS A total of 204 bovine enamel samples were embedded in acrylic resin and allocated to 17 groups (n=12). The specimens were eroded in an artificial mouth (3 days; 6×30 s/days, flow rate: 2 ml/min) using citric acid (pH: 2.5). Immediately after the erosive attacks, saliva substitutes (12 sprays, 3 gels...

Development of a Remineralizing Saliva Substitute and Effects of Various Saliva Substitutes in Combination with Fluorides on Enamel and Dentin

Galvanic Corrosion of Orthodontic Brackets and Wires in Acidic Artificial Saliva: Part II

  Objective: Orthodontic wires should have high resistance against corrosion in the oral environment. Since the effect of pH on corrosion has been well recognized, this study sought to assess and compare the electrochemical corrosion of orthodontic brackets and wires of different brands in acidic artificial saliva.   Methods: This in vitro experimental study was conducted on 24 mandibular centr...

Influence of self-made saliva substitutes on tribological characteristics of human enamel.

This paper describes the results of tests on the influence of human saliva and its substitutes on tribological characteristics of friction pairs. Each pair consists of enamel and one of the following materials: ceramics, the Meridian B2 dental composite, the GK dental amalgam, and Ti-6Al-4V titanium alloy. The saliva substitutes used were prepared using pyrophosphates, xanthan gum, and mucins d...
