I-Peptides equkethe ukuphindaphinda kwe-8 ye-aspartate-serine-serine (8DSS) iboniswe ukukhuthaza i-nucleation ye-calcium phosphate kwisisombululo kwi-enamel yomntu.Apha siye savavanya amandla e-8DSS ukukhuthaza ukuvuselelwa kwakhona kwe-enamel encitshisiweyo kwimodeli ye-in vitro ye-caries yokuqala ye-enamel.Izilonda zokuqala ze-caries zenziwe kwiibhloko ze-enamel yenkomo, ezathi ke zaphantsi kwe-12 d ye-pH yokuhamba ngebhayisikile kubukho be-25 µM 8DSS, 1 g/L NaF (ulawulo olulungileyo) okanye i-buffer yodwa (ulawulo olubi).Ukufunxwa kwe-8DSS kwaqinisekiswa yi-X-ray photoelectron spectroscopy.Ilahleko yezimbiwa, ubunzulu bomonakalo, kunye nomxholo weeminerali kumphezulu ongaphezulu kunye nobunzulu obuhlukeneyo bomzimba wesilonda zahlalutywa ngaphambi nangemva kokuhamba ngebhayisikile nge-pH ngepolarized light microscopy kunye ne-transverse microradiography.Ilahleko yamaminerali emva kokuhamba ngebhayisikile ye-pH yayisezantsi kakhulu kwiisampulu ze-8DSS kunesampulu ze-buffer-kuphela, kwaye izilonda kwiisampulu ze-8DSS zazingaphantsi kakhulu.Iisampulu ezinyangwe nge-8DSS zibonise isiqulatho seminerali esiphezulu kakhulu kunesampulu ze-buffer-kuphela kummandla osuka kumaleko womphezulu (30 µm) ukuya kumndilili wobunzulu bomonakalo (110 µm).Akukho mahluko ubalulekileyo afunyenweyo phakathi kweesampuli eziphathwe nge-8DSS kunye nezo ziphathwe nge-NaF.Ezi ziphumo zibonisa ukuba i-8DSS inamandla okukhuthaza ukuxutywa kwakhona kwe-enamel ye-demineralized.
