    EFFECT OF DIFFERENT ESSENTIAL OILS ON HUMAN DENTINE STRUCTURE
    (Soc Stiinte Farmaceutice Romania, 2017) Zgarian, Roxana Gabriela; Iacob, Filip; Kaya, Durmus Alpaslan; Rau, Ileana; Voicu, Georgeta; Tihan, Gratiela Teodora
    This paper revealed the effect of Oregano, Rosmarinus and Myrtus essential oils on the dentine structure stability for the improvement of collagen resistance against enzymatic activity. Several techniques were used: Fourier Transform Infrared Spectroscopy (FTIR), enzymatic degradation and Scanning Electron Microscopy (SEM). Results showed that all studied oils acted as protective films on the dentine after digestion of collagenase, even if the Oregano or Myrtus essential oils caused a demineralization process at the beginning. The oil treated slabs presented a significant lower mass loss than the non-treated slab after the action of the collagenase. This fact indicates a beneficial impact of these essential oils on the stability of the dentine.
