Sažetak
The oral cavity is a microbial habitat with over 700 species that live in harmony with the human body [1]. Hard dental tissues include dentin, cementum and enamel which makes main building material of teeth. This is a group of tissues that was subjected to various degrees of mineralization during development, which is typically in the form of hydroxyapatite. Because of their environment teeth interact continuously with physiological fluids, containing biologically important ionic species [2]. The behavior of this species can affect the solid, the environment and biological system. Recently, it was shown that low temperature atmospheric pressure plasma jet (APPJ) could be applicable to therapies in field of dental medicine [3]. The opportunity to examine and understand interactions between APPJ and hard dental tissue has not been fully exploited particularly at the fundamental level where surface science techniques can provide detailed information [4]. To asses interaction between APPJ and hard dental tissue, XPS, AFM, OES and contact angle measurements were conducted. Sample preparation for surface techniques will be discussed in sufficient detail. After the treatment with APPJ chemical, morphological and wettability changes were revealed on the surface of the dentin and enamel. This results bring APPJ closer to clinical application in dental medicine [5, 6]. [1] Pennisi E. A mouthful of microbes. Science (New York, NY). 2005 ; 307(5717):1899-901. [2] Dorozhkin S.
