Peptides ine 8 inodzokororwa yeaspartate-serine-serine (8DSS) yakaratidzwa kukurudzira nucleation ye calcium phosphate kubva kune mhinduro mune enamel yemunhu.Pano takaedza kugona kwe8DSS kusimudzira kudzoreredzwa kwe demineralized enamel mune in vitro modhi yeyakagadzirwa yekutanga enamel caries.Maronda ekutanga caries akagadzirwa mu bovine enamel blocks, ayo akazoiswa pasi pe12 d yepH kubhasikoro pamberi pe25 µM 8DSS, 1 g/L NaF (positive control) kana buffer chete (negative control).Kutorwa kwe8DSS kwakasimbiswa neX-ray photoelectron spectroscopy.Kurasika kwezvicherwa, kudzika kweronda, uye zvicherwa zviri pamusoro pedenga uye pakadzika kwakasiyana kwemuviri wekukuvadza zvakaongororwa pamberi uye mushure mepH kubhasikoro nepolarized light microscopy uye transverse microradiography.Kurasika kwezvicherwa mushure mekutenderera kwepH kwakadzikira zvakanyanya mumasampuli e8DSS kupfuura mumasampureti e-buffer-chete, uye maronda mumasampuli e8DSS aive asina kudzika zvakanyanya.Samples dzakabatwa ne8DSS dzakaratidza zvakanyanya kukwirisa zvicherwa pane mabuffer-chete samples mudunhu rinokwira kubva pamusoro pedenga (30 µm) kusvika paavhareji kudzika kweronda (110 µm).Hapana misiyano yakakosha yakawanikwa pakati pemasampuli akabatwa ne8DSS uye ayo akabatwa neNaF.Izvi zvakawanikwa zvinoratidza kuti 8DSS ine mukana wekusimudzira remineralization ye demineralized enamel.
