Niba igihombo cyumusatsi nikibazo kubantu bakuru, noneho kubora amenyo (izina rya siyansi caries) ni ikibazo rusange kubantu bafite imyaka yose.

Nk'uko imibare ivuga ko ingana z'inyoni zitera mu rubyinginzi mu gihugu cyanjye zirenga 50%, abantu benshi bafite imyaka irenga 80 ari hejuru ya 80%, kandi mu bageze mu za bukuru bari hejuru ya 95%. Niba bidafashwe igihe, iyi ndwara isanzwe ya bagiteri igoye igatera Pulpitis na fagitire ya apical, ndetse ikanatera amagufwa ya alveolar hamwe namagufwa ya urwanyi, bizagira ingaruka zikomeye mubuzima nubuzima bwumurwayi. Noneho, iyi ndwara ishobora kuba yarahuye n '"Nemesi."

Muri sosiyete y'Abanyamerika (AC) inama n'imurikagurisha ndetse n'imurikagurisha ryavuye muri kaminuza ya Illinois i Chicago rishobora kubuza imiterere y'icyorezo cy'inanga n'iryinyo yo kwangirika mu munsi umwe. Kugeza ubu, abashakashatsi basabye ipatanti, kandi imyiteguro irashobora gukoreshwa cyane mu mavuriro y'amavuko mu gihe kizaza.

Hariho ubwoko bwa bagiteri burenga 700 mukanwa k'umuntu. Muri bo, nta gisirikare y'ingirakamaro ari cyo gifasha gusya ibiryo cyangwa kugenzura izindi mikorobe, ariko nanone bagiteri zangiza inans. Bagiteri nkizo zishobora gukurikiza amenyo no guteranya igihano cyo gukora "biofilm", bigatuma acide of trode ofth iryiza enamel, bityo bigatuma inzira "yo kubora amenyo".

Ubuvuzi, fluoride flooride, stannous sluoride, sidanda nitrate cyangwa ifeza ya fayine ikoreshwa muguhagarika plaque yinyomoza kandi ikakubuza guterana amenyo. Hariho kandi ubushakashatsi bugerageza gukoresha nanoparticles yakozwe muri zinc oxide, oxide yumuringa, nibindi kugirango ifate amenyo. Ariko ikibazo nuko hari amenyo arenga 20 mu cyuho cyabantu, kandi bose bafite ibyago byo guhindurwa na bagiteri. Gukoresha inshuro nyinshi kuri ibi biyobyabwenge birashobora kwica selile zingirakamaro ndetse bigatera ikibazo cyo kurwanya ibiyobyabwenge bya bagiteri zangiza.

Abashakashatsi rero bizeye ko bazabona uburyo bwo kurengera bagiteri y'ingirakamaro mu munwa no gukumira amenyo. Bahinduye ibitekerezo byabo kuri ceride oxide nanoparticles (formulaire ya molecular: chaso2). Igice nikimwe mubikoresho byingenzi bya antibatege kandi bifite ibyiza byuburozi buke kuri selile zisanzwe hamwe nubukoresha budasanzwe bushingiye kubihinduka. Muri 2019, abashakashatsi baturutse muri kaminuza ya Nankkai basuzumye gahunda yuburyo bushoboka bwa antibacterialCerium oxide nanoparticlesmu bumenyi bw'Ubushinwa.

Raporo y'abashakashatsi muri iyo nama ivuga ko bakoze cerium oxide nanoparticles bashonga cerium nitrate cyangwa amonimium sulfate, kandi biga ingaruka z'ibice kuri "biofilm" byakozwe na StreptococCcus. Ibisubizo byerekanaga ko nubwo cerium oxide nanoparticles idashobora gukuraho "biofilm" ihari, bagabanije iterambere rya 40%. Mubihe bisa, izwi cyane izwi cyane anti-cavity agent feza sidanda ntishobora gutinza "biofilm". Iterambere rya "membrane".

Umushakashatsi w'ingenzi w'umushinga, Russell Pesivento wo muri kaminuza ya Illinois i Chicago, yagize ati: "Ibyiza by'ubu buryo bwo kuvura ni uko bigaragara ko ari bibi cyane kuri bagiteri. Nanoparticles izakumira mikoroguro gusa yo gukurikiza ibintu no gukora biofilm. Kandi uburozi bwuburozi n'imiterere ya metabolic kuri selile zo mu kanwa ka muntu mu isahani ya petri iri munsi ya feza iri mu buvuzi busanzwe. " 

Kugeza ubu, ikipe iragerageza gukoresha amata yo gutuza nanoparticles kuri ph idafite aho ibogamiye cyangwa idahwitse ya alkaline hafi ya saliva. Mu bihe biri imbere, abashakashatsi bazagerageza ingaruka ziyi mikorere kuri selile yabantu murwego rwo hepfo yigifu muburyo bwuzuye bwa microbive muri mikorobe yuzuye ya mikorobe yuzuye ya microbial, kugirango bahe abarwayi bafite umutekano mwiza muri rusange.
