Yog tias cov plaub hau poob yog ib qho teeb meem rau cov neeg laus, tom qab ntawd cov hmoov txhuam hniav) yog ib qho teeb meem mob hlwb) yog ib qho teeb meem mob taub hau rau cov neeg ntawm txhua lub hnub nyoog.

Raws li kev txheeb cais, qhov xwm txheej ntawm cov neeg kho hniav ntawm cov neeg nyob hauv kuv lub tebchaws yog ntau tshaj li 80%, thiab cov neeg laus, cov feem sib npaug yog tshaj li 95%. Yog tias tsis kho lub sijhawm twg, cov kab mob no ua rau cov kab mob caj dab thiab ua rau mob pob txha, pob txha ua pob txha, uas yuav cuam tshuam rau kev noj qab haus huv thiab lub neej ntawm tus neeg mob. Tam sim no, tus kab mob no yuav tau ntsib ib qho "nemesis."

Hauv tebchaws Asmeskas cov neeg siv tshuaj (acs) Virtual Sib Tham thiab Kev Tshawb Fawb hauv Lub Caij Nplooj Siab Nanoparticy tsim uas tuaj yeem tiv thaiv kev tsim cov quav hniav hniav thiab hniav lwj hauv ib hnub. Nyob rau tam sim no, cov kws tshawb nrhiav tau thov rau patent, thiab kev npaj yuav siv dav hauv chaw kho hniav yav tom ntej.

Muaj ntau dua 700 hom kab mob hauv tib neeg lub qhov ncauj. Ntawm lawv, tsis muaj cov kab mob muaj txiaj ntsig nkaus xwb uas pab cov zaub mov zom lossis tswj cov kab mob phom sij, tab sis kuj cov kab mob ua rau muaj kev phom sij nrog rau Streptococcus mutans. Cov kab mob phem no tuaj yeem ua raws li cov hniav thiab sib sau ua "biofilm", haus cov piam thaj thiab tsim cov kua txiv hmab txiv ntoo uas corrode hniav txha hniav sib dhos, yog li paving txoj kev rau "hniav lwj".

Clinically fluoride, nyiaj nitrate, nyiaj nitrate lossis nyiaj diamine fluoride feem ntau yog siv los tiv thaiv cov quav hniav hniav thiab tiv thaiv kom txhob hniav ntxiv. Kuj tseem muaj cov kev tshawb fawb uas sim siv nanoparticles ua los ntawm zinc oxide, tooj liab oxide, etc. txhawm rau kho hniav. Tab sis qhov teeb meem yog tias muaj ntau dua 20 tus hniav hauv tib neeg qhov fab, thiab txhua tus muaj kev pheej hmoo ntawm cov kab mob. Kev siv cov tshuaj uas tua tau cov tshuaj ntawm cov tshuaj muaj txiaj ntsig thiab tseem ua rau muaj teeb meem ntawm cov tshuaj tiv thaiv ntawm cov kab mob phom sij.

Yog li, cov kws tshawb nrhiav kev cia siab tias yuav nrhiav txoj hauv kev los tiv thaiv cov kab mob tau txais txiaj ntsig zoo hauv qhov ncauj thiab tiv thaiv kom txhob hniav lwj. Lawv tig mus rau cerium oxide nanoparticles (molecular cov mis: CEO2). Lub particle yog ib qho tseem ceeb ntawm cov tshuaj tua kab mob tseem ceeb thiab muaj qhov zoo ntawm cov tshuaj lom tsawg thiab cov tshuaj tua kab mob uas tau hloov dua siab tshiab. Xyoo 2019, cov kws tshawb nrhiav los ntawm Nankai University systems tau tshawb xyuas cov tshuaj tua kab mob taucerium oxide nanoparticlesHauv cov ntaub ntawv tshawb fawb Tuam Tshoj.

Raws li cov kws tshawb nrhiav cov lus qhia ntawm lub rooj sablaj, lawv tau ua cerium oxide nitrate ntawm cov khoom "biofilm" tsim los ntawm Streptococcus mutans. Cov txiaj ntsig tau pom tias txawm hais tias lub cerium oxide nanoparticles tsis tuaj yeem tshem tawm cov muaj sia nyob "biofilm", lawv txo nws txoj kev loj hlob los ntawm 40%. Nyob rau hauv cov xwm txheej zoo ib yam li no, cov neeg sawv cev sib tua, tus neeg sawv cev sib tua nyiaj yog nitrate tsis tuaj yeem ncua "biofilm". Kev txhim kho ntawm "membrane".

Tus kws tshawb fawb tseem ceeb ntawm txoj haujlwm, Russell Cov Illinois ntawm Chicago ntawm Chicago, hais tias: "Qhov zoo dua ntawm txoj kev kho mob no yog tias nws zoo li tsis muaj kev phom sij rau qhov ncauj kab mob. Nanoparticles tsuas yog tiv thaiv cov kab mob me me los ntawm kev ua yeeb yam rau cov khoom thiab tsim ib lub biofilm. Thiab cov particle kev lom zem thiab cov kev mob metabolic ntawm cov hlwb hauv lub cev hauv cov tais petri muaj tsawg dua li nyiaj kho mob. " 

Tam sim no, pab pawg yog sim siv cov txheej txheej kom ruaj khov rau cov nanoparticles ntawm qhov nruab nrab lossis tsis muaj zog alkaline pH Kaw rau ntawm cov qaub ncaug ntawd. Yav tom ntej, cov kws tshawb nrhiav yuav sim cov nyhuv ntawm cov kev kho mob ntawm tib neeg hauv lub plab muaj kev nyab xeeb ntau dua kev ruaj ntseg.
