ABSTRACT
This paper describes the results of tests on the influence of human saliva and its substitutes on tribological characteristics of tested 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 used saliva substitutes had been prepared using pyrophosphates, xanthan gum, and mucins dissolved in a saline buffer. The results of the presented tribological tests show that the values of the tested parameters (coefficient of friction and linear wear) that were researched were different from each other. Some similarity was observed between the evaluated level of wear characteristics after the friction process in the environment of human saliva and of that in the environment of one of the tested mucins. The performed microscopic observations of surfaces of the enamel samples after friction revealed varied forms of tribological wear.
