  • Title: [The development of initial enamel caries--a phenomenon of interfacial reactions].
    Author: Rentsch H, Merte K, Wörtz S, Zschau E, Plier F, Otto G.
    Journal: Zahn Mund Kieferheilkd Zentralbl; 1990; 78(3):217-21. PubMed ID: 2144085.
    Abstract:
    The investigation deals with earliest chemical changes in outermost enamel surfaces during initial caries development. After in vitro demineralization of enamel samples in acidulated hydroxyethylcellulose solution (pH = 5.1) for periods between 1 and 288 h the Ca/P molar ratios were determined in depths of 0.04 micron using the Rutherford Backscattering spectroscopy. The measured Ca/P ratios oscillate around the initial value. This behaviour is interpreted as a combined de/remineralization process.
