Biology ntawm Plaque thiab hniav lwj
Cov quav hniav tsis yog tsuas yog cov khoom noj khoom haus; Nws yog ib qho kev sib koom ua ke biofilm uas muaj cov kab mob embedded nyob rau hauv ib tug nplaum matrix ntawm polymers. Cov kab mob no metabolize suab thaj los ntawm cov zaub mov thiab tsim cov kua qaub ua cov khoom lag luam. Cov kua qaub demineralize hniav enamel, cov khoom nyuaj tshaj plaws nyob rau hauv tib neeg lub cev, nyob rau hauv ib tug txheej txheem uas yuav siv sij hawm li 20 mus rau 30 feeb tom qab noj mov. Cov qaub ncaug ua raws li lub cev tiv thaiv ntuj, ntxuav tawm cov khoom noj, nruab nrab acids, thiab muab calcium thiab phosphate ions rau remineralization. Txawm li cas los xij, thaum acid tawm tsam tshaj cov txheej txheem kho ntuj, kab noj hniav tsim.
Lub luag haujlwm ntawm fluoride hauv Remineralization
Fluoride tau yog ib qho tseem ceeb tshaj plaws ntawm pej xeem kev noj qab haus huv nrhiav pom hauv kev tiv thaiv cov hniav lwj. Nws ua haujlwm los ntawm ntau lub tswv yim: inhibiting cov kab mob acid ntau lawm, txhim kho enamel tiv thaiv cov kua qaub tawm tsam, thiab tseem ceeb tshaj plaws, txhawb nqa remineralization. Thaum muaj fluoride nyob rau hauv cov txheej txheem remineralization, nws integrates rau hauv lub enamel siv lead ua qauv, tsim fluorapatite - ib tug compound ntau resistant rau acid dua cov thawj hydroxyapatite ntxhia. Qhov no yog vim li cas fluoride hauv tshuaj txhuam hniav, tshuaj ntxuav qhov ncauj, thiab cov khoom siv dej hauv zej zog tseem yog lub hauv paus ntawm kev tiv thaiv kab noj hniav.
Kab mob ntawm cov pos hniav: Tus kab mob ntsiag to
Kab mob periodontal, cuam tshuam ze li ib nrab ntawm cov neeg laus hnub nyoog 30 xyoo, pib ua gingivitis-mob ntawm cov pos hniav tshwm sim los ntawm cov quav hniav. Cov tsos mob muaj xws li liab, o, thiab los ntshav thaum txhuam hniav. Thaum tsis kho, qhov mob tuaj yeem ua rau muaj kab mob periodontitis, qhov twg cov kab mob ua rau lub cev tiv thaiv kab mob uas ua rau cov pob txha txhawb nqa thiab cov ntaub so ntswg nyob ib ncig ntawm cov hniav. Cov lus teb inflammatory tso tawm cytokines thiab lwm tus neeg nruab nrab uas taug kev los ntawm cov hlab ntsha, ua rau muaj kab mob hauv lub cev. Cov txheej txheem no piav qhia txog qhov zoo -cov ntaub ntawv sib koom ua ke ntawm cov kab mob hauv lub cev thiab muaj kev pheej hmoo siab rau kev mob plawv, mob stroke, thiab teeb meem hauv kev tswj ntshav qab zib rau cov neeg mob ntshav qab zib.
Siv Tau Txhua Hnub Kev Kho Hniav Qhov ncauj raws tu qauv
Lub hauv paus ntawm kev saib xyuas qhov ncauj zoo txuas ntxiv dhau ntawm tus txhuam hniav. Ib txoj haujlwm tseem ceeb suav nrog: txhuam hniav nrog cov tshuaj txhuam hniav fluoride tsawg kawg yog ob feeb, ob zaug ib hnub, siv cov lus tsa suab; ntxuav cov hniav ntawm cov hniav siv txhuam hniav los yog txhuam hniav, uas tshem tawm cov quav hniav los ntawm cov chaw uas txhuam hniav txhuam tsis tuaj yeem ncav cuag; siv cov tshuaj tua kab mob hauv qhov ncauj kom txo cov kab mob, tab sis qhov no yuav tsum tsis txhob hloov kho tshuab; thiab ntxuav tus nplaig, qhov chaw muaj cov kab mob tseem ceeb nyob. Qhov kev txiav txim tseem ceeb: kev txhuam hniav ua ntej txhuam hniav tau pom tias ua tau zoo dua ntawm kev txo cov quav hniav.
Cov Txheej Txheem Tshaj Tawm hauv Kev Kho Hniav
Kev saib xyuas qhov ncauj niaj hnub no tau hloov zuj zus los ntawm ib qho -loj- haum- tag nrho cov kev daws teeb meem rau tus kheej txoj hauv kev. Kev nce qib hauv kev nkag siab txog microbiome hauv qhov ncauj tab tom ua txoj hauv kev rau probiotics, prebiotics, thiab lwm yam microbiome- hloov cov khoom. AI-cov cuab yeej siv tau muab cov lus qhia tiag tiag- lub sijhawm tawm tswv yim ntawm cov txheej txheem txhuam hniav, thaum nyob hauv - cov khoom siv kuaj hauv tsev tuaj yeem saib xyuas cov kab mob thiab cov caj ces cuam tshuam rau cov teeb meem hniav. Cov kev tsim kho tshiab muaj txiaj ntsig tseem tab tom hloov cov qeb, nrog cov ntaub ntawv biodegradable, ntsiav tshuaj-raws li cov qauv, thiab cov khoom ntim rov qab uas txo cov pov tseg yas.
Kev Sib Txuas Rau Kev Noj Qab Haus Huv Tag Nrho
Qhov ncauj- kev sib txuas hauv qhov ncauj txhawb ntxiv tias kev noj qab haus huv ntawm qhov ncauj yog ib qho tseem ceeb ntawm kev noj qab haus huv tag nrho. Cov tib neeg uas muaj mob xws li ntshav qab zib, kab mob plawv, lossis lub cev tiv thaiv kab mob tsis muaj zog tuaj yeem xav tau kev kuaj hniav ntau zaus- nce thiab ntau dua kev saib xyuas txhua hnub. Kev mus ntsib kws kho hniav tsis tu ncua tseem yog qhov tseem ceeb rau kev tu cov kws tshaj lij thiab tshawb pom cov teeb meem ntxov, nrog ntau tus kws tshaj lij pom zoo mus ntsib txhua rau lub hlis rau cov tib neeg noj qab haus huv thiab ntau zaus rau cov neeg muaj kev pheej hmoo.
