                         oxide/graphene oxide (MWCNTO/GO), nanohydroxyapatite (nHAp) and 
                         combination of them together or not to acidulated phosphate 
                         fluoride gel (F) have been tested as protective coating before 
                         root dentin erosion. Fourteen bovine teeth were cleaned, polished, 
                         divided into two parts (n=28) and assigned to seven groups: 
                         (Control) - without previous surface treatment; F treatment; nHAp; 
                         MWCNTO/GO; F+nHAp; F+MWCNTO/GO and F+MWCNTO/GO/nHAp composites. 
                         Each sample had two sites of pre-treatments: acid etched area and 
                         an area without treatment. After the biomaterials application, the 
                         samples were submitted to six cycles (demineralization: orange 
                         juice, 10 min; remineralization: artificial saliva, 1 h). Micro 
                         energy-dispersive X-ray fluorescence spectrometry (mu-EDXRF) 
                         mapping area analyses were performed after erosive cycling on both 
                         sites (n=84). mu-EDXRF mappings showed that artificial saliva and 
                         MWCNTO/GO/nHAp/F composite treatments produced lower dentin 
                         demineralization than in the other groups. Exposed dentin tubules 
                         allowed better interaction of nanobiomaterials than in smear layer 
                         covered dentin. Association of fluoride with other biomaterials 
                         had a positive influence on acid etched dentin. MWCNTO/GO/nHAp/F 
                         composite treatment resulted in levels of demineralization similar 
                         to the control group.",
