Cov evolution ntawm kev kho hniav, los yog yuav ua li cas los kho caries nyob rau hauv lub nanotechnology era?

Kev Kho Hniav teeb meem , muaj ntau ntau raws li muaj cov neeg. Thawj cov hniav puas vim tsis txaus zaub mov ua, cov neeg pluag qhov ncauj thiab tsis muaj kev kho mob. Tam sim no, cutters thiab hauv paus txawm raug kev txom nyem vim hais tias ntawm cov loj loj xaiv ntawm cov zaub mov, mas overly ua thiab qab zib, tag nrho cov tau ua txhaum ntawm lub hauv paus ntsiab lus ntawm cov khoom noj kom thiab txoj kev ua neej. Tab sis lub theem ntawm kev loj hlob ntawm niaj hnub kho hniav yuav ua rau nws yooj yim mus teb cov lus nug: "Yuav ua li cas mus kho cov hniav lwj?", Kom qhia nws mus rau lub heev thaum ntxov rau theem thiab maj txoj kev mus kho rau ib qho chaw twg rau tus kws kho mob.

Kab noj hniav los yog qhov nyob rau hauv cov hniav

Caries - ib tug pathological kev puas kho hniav ntaub so ntswg, uas ua rau tsim muaj kab noj hniav. Thaum lub sij hawm tus txheej txheem no, kho hniav nyuaj cov ntaub so ntswg softened thiab demineralized. Txawm li cas los ntawm ib yam ntawm cov plaub theem ntawm tus kab mob yog kev puas tsuaj, tab sis nyob rau hauv thawj theem kab mob no yog tsuas qhia nyob rau hauv tsis yog detectable kev puas tsuaj enamel, tsis muaj mob. Tus thawj theem yuav siv sij hawm qhov chaw yuav luag tsis paub los ntawm tus txiv neej. Yog li ntawd, nyob rau ntawm no theem, cov lus teb rau lo lus nug li cas los kho caries, ib qho yooj yim - nrog rau cov kev pab los ntawm qhia tshwj xeeb uas xaiv kev tu cev cov khoom (tshuaj txhuam hniav, txhuam hniav, thiab lwm yam).

Qhov seem cov kauj ruam coj qhov chaw nrog rau cov kev nce ntawm mob rhiab heev rau ib tug ntau yam ntawm stimuli, tshuaj (qaub, qab zib) kub (txias, kub) thiab mechanical (khoom noj). Thaum qhov no yog qhov tshwm sim los ntawm cov kab noj hniav ntawm txawv ntau thiab tsawg thiab cov neeg kawm ntawv ntawm kev puas tsuaj.

kev kho mob

Nyob rau hauv dav dav, lub txoj kev ntawm kev kho mob ntawm kev kho hniav caries muaj xws li qhov kev tshem tawm ntawm puas qhov chaw ntawm lub ntxiv filling ntawm lub puas cheeb tsam check cov ntaub ntawv uas ntsaws. Lub puas feem kaw tshwj xeeb phaj los yog veneer.

Luv luv txog lub ntsaws ruaj ruaj

Filling ntaub ntawv raug muab faib ua ntau yam muaj pes tsawg leeg cements, yas, composites thiab cov hlau ntsaws. Yog tsis muaj kev foob yog tsis yooj yim sua kom tiv nrog ib qho teeb meem - yuav ua li cas los kho caries. Maas tab sis yog pheej yig heev cov ntaub ntawv uas, tab sis nws yog tag rau tus xov tooj ntawm cov xim, nws yog phem "glued" rau tus hniav nto, thiab heev taus. Yas thiab composites sai sai erased thiab hloov lawv cov xim. Siv hlau los ntsaws, nyob rau hauv cov kev phem ntawm nws exceptional zog thiab durability, muaj ib tug unpleasant nws yog xim hlau xim thiab tsw.

Niaj hnub nimno composites photopolymer tsis muaj drawbacks ntawm lub saum toj no cov ntaub ntawv thiab muaj cov loj loj tus naj npawb ntawm zoo. Polymers txig koom, glued mus rau cov hniav nto, lawv yog check heev, lawv ntxoov ntxoo ruaj khov rau xyoo lawm, lawv yog resistant rau puas. Nyob rau hauv tas li ntawd, ib tug ntau yam ntawm cov xim thiab ntxoov ntawm no cov ntaub ntawv uas pab kom xaiv ntawm lub zoo meej piv ntawm lub ntuj luag ntawm tus neeg mob. Lub polymer yog tshuam recreates ib tug tej thaj chaw deb ntawm tus hniav. Yog li, nws yog ua tau los los yog ib feem, los yog tsim zoo ib tug tag nrho cov hniav. Zoo li lub cutter los yog cov haiv neeg yuav tsis tau sib txawv los ntawm tus thawj thiab tej yam ntuj tso. Tab sis lwm cov ntaub ntawv tseem siv nyob rau hauv kev kho hniav. Piv txwv li, raznosortnyh cements siv nyob rau hauv xyuas kev xyaum, vim hais tias lawv muaj tsawg toxicity, raws li zoo raws li cov laus - raws li ib lub hauv paus rau photopolymeric ntsaws los yog me kho. Yas - mus tshem tawm me me plab teeb meem, rau nruab ib ntus ntsaws los yog raws li koom haum pab cov ntaub ntawv.

Tab sis nyob rau hauv kev phem ntawm lub loj loj xaiv ntawm cov ntaub ntawv rau kev kho hniav, tsis muaj leej twg ntawm lawv yuav tsis hloov tej yam ntuj tso cov hniav. Tsuas yog lawv yog qhov zoo tshaj plaws, tsim los ntawm qhov rau tib neeg. Thiab tsis muaj caries kev kho mob tsis yog ib tug panacea rau cov teeb meem no. Thaum caries paub qab hau cov neeg kho li cas? Tsuas yog kab prophylaxis ntawm inflammatory kev ntawm lub qhov ncauj kab noj hniav yog lub feem ntau yooj yim, npaum thiab yog kev txiav txim siab.

Kev tiv thaiv raws li cov haib tshaj riam phom tiv thaiv kab mob

Caries Tiv Thaiv muaj xws li kev zam yam yuav ua tau rau tus kab mob no, thiab ua rau kom cov nqaij mos kuj mus teeb meem influences. Tej zaum pib optimally tu thiab tiv thaiv txawm thaum lub sij hawm me nyuam hauv plab kev loj hlob ntawm tus me nyuam thiab tsis tas txog thaum ib tug ripe laus muaj hnub nyoog. Dua li ntawm qhov simplicity ntawm cov kev ua ub, lawv lub hwj chim thiab efficiency yog enormous.

Meej pem kev noj haus, ib tug tag nrho thiab xuas, tsis muaj kab mob - tu kev cai, ib tug noj qab nyob zoo txoj kev ua neej - qhov no yog qhov zoo tshaj plaws cov lus teb rau ib tug ntsiag to thiab mob "yuav ua li cas los kho caries ???". Nws yog qhov zoo tagnrho riam phom nyob rau hauv qhov kev sib ntaus nrog rau feem ntau kev mob nkeeg, cov Tib yam siv rau kev kho hniav muaj kab mob. Tsis txhob kariesprovotsiruyuschih ntau yam (qab zib thiab mos cov khoom noj, qhov ua txhaum tej yam ntuj tso alkaline ib puag ncig nyob rau hauv lub qhov ncauj kab noj hniav, kom tsawg ntawm cov kub dhau heev lawm thiab cov zaub mov txias, kev siv ntawm canines li openers schelkushki li al.) Yuav tau tig mus ua si rau tus kws kho hniav nyob rau hauv cov ntaub ntawv ntawm lub kho-prophylactic.
