Kana kurasikirwa kwebvudzi idambudziko kune vakuru, saka zino kuderera (yesainzi zita rechida) idambudziko rakajairika remusoro wevanhu veese mazera.

Sekureva kwehuwandu, zviitiko zvemazino caries pakati penyika yangu zvinopfuura makumi mashanu muzana, chiitiko chemazino, uye pakati pevakweguru, chikamu chinopfuura 95%. Kana isina kubatwa munguva, izvi zvakajairika mazino akaomeswa tishu tisse chirwere chinokonzeresa uye apical periodontitis, uye kunyange kukonzera kupfupika kwepfuma uye nejaya pfupa, iyo ichakanganisa zvakanyanya hutano nehupenyu hwemurwere. Zvino, chirwere ichi chinogona kunge chakasangana ne "Nemesis."

KuAmerican Chemical Sosaiti Parizvino, vatsvagiri vakanyorera patent, uye gadziriro inogona kushandiswa zvakanyanya mumakompiniki emazino mune ramangwana.

Kune marudzi anopfuura mazana manomwe emabhakitiriya mumuromo memunhu. Pakati pavo, hapana mabhakitiriya anobatsira chete anobatsira kuchera chikafu kana kudzora mamwe mikana, asiwo mabhakitiriya anokuvadza kusanganisira hutachiona hwehutachiona. Buttiika inokuvadza kudaro inogona kuomerera kumeno uye kuungana kuti aumbe "biofilm", pamba mashuga uye ubudise acidic byproducts kuti corrode enamel enamel, nekudaro achiratidza nzira ye "zino kuderera".

Clinically, Stannous Fluoride, Silver Nitrate kana Sirivheri DiAmine Fluoride inowanzoshandiswa kuti inhibit dental plaque uye kudzivirira zvimwe zino kuderera. Pane zvimwewo zvidzidzo zviri kuedza kushandisa nanharticles yakagadzirwa ne zinc oxide, mhangura oxide, etc. kubata mazino kuora. Asi dambudziko nderekuti kune meno anopfuura makumi maviri muchirongo chemuromo, uye vese vari panjodzi yekupararira mabhakitiriya. Iko kudzokorora kushandiswa kweaya madhiragi kunogona kuuraya masero anobatsira uye kunyange kukonzera dambudziko rekupesana nemishonga yebhakitiriya inokuvadza.

Naizvozvo, vatsvagiri vanotarisira kuwana nzira yekuchengetedza mabhakitiriya anobatsira mune yemuromo yemuromo uye kudzivirira zino kuderera. Vakatendeukira kune yavo cerium oxide naneoparticles (moleky formula: CEO2). Iyo tangi ndeye chimwe chezvinhu zvakakosha zveAntibacterial zvinhu uye zvine zvakanakira kuderera kwehupfumi kune zvakajairika masero uye iyo antibacterial mechanism inotsanangurira kushandurwa kwekushandurwa. Muna 2019, vaongorori vanobva kuNankai yunivhesiti zvakarongeka zvakarongeka zvinokwanisika zvinogoneka antibacterial mechanism yecerium oxide naneoparticlesmuSainzi China Zvishandiso.

Sekureva kweVanyori veMutsvagiro pamusangano, ivo vakagadzira cerium oxide naneparticles nekunyungudika kwemvura, uye vakadzidza mhedzisiro yeiyo "Biofilm" yakagadzirwa neRimba neTritrikcccus. Mhedzisiro yacho yakaratidza kuti kunyangwe iyo cerium oxide naneoplticles haina kukwanisa kubvisa "biofilm" iripo, ivo vakadzora kukura kwayo ne40%. Mumamiriro ezvinhu akafanana, kiriniki inozivikanwa anti-cavity Agent Silt nitrate haina kukwanisa kunonoka "Biofilm". Kuvandudzwa kwe "membrane".

Muongorori mukuru weprojekiti, Russell phsave peyunivhesiti yeIlinois kuChicago, akati: Nuoparticles ichangotadzisa microorganisms kubva kuanamatira kune chinhu uye kuumba biofilm. Uye kuine utsi hwenhumbu uye metabolic mhedzisiro pamasero emuromo wemumuromo mune petri ndiro iri pasi pesirivheri inotungamira mukurapwa kwakajairika. " 

Parizvino, timu iri kuyedza kushandisa zvombo kuti zvitumbise nanharticles pane isina kwayakarerekera kana isina kusimba alkaline ph padyo neiyo yemazita. Mune ramangwana, vatsvagiri vanoedza mhedzisiro yekurapa uku pamasero emunhu mune yakadzika yekugaya turakiti mune yakakwana yerudzi rwechirume, kuitira kuti varwere vane pfungwa dzakanaka dzekuchengetedza.
