Peb yog leej twg - cov programmers yooj yim lossis cov thawj coj ntawm cov tuam txhab loj - peb npau suav ntawm lub luag haujlwm zoo nkauj daus-dawb.
Nyob rau tib lub sijhawm, kev ntshai (ntau tus kws kho mob), peb ntshai ntawm kws kho hniav thiab faint ntawm qhov pom ntawm kev xyaum.
Tsis xav tsis thoob, tib neeg tau concocted ntau myths txog kev noj qab haus huv ntawm qhov ncauj. Cov hniav noj qab haus huv - qhov no yog kev zoo siab heev. Cia peb nyob me ntsis "mythbusters" thiab tshem tawm cov kev xav tsis zoo tshaj plaws txog peb cov hniav.
Lus dab neeg 1. Tsawg yog ntau
NW nyuam qhuav sawv, ib nrab qhib peb lub qhov muag, peb mus rau hauv chav dej. Chav dej. Da dej. Txhuam txhuam hniav (5 feeb! Tsis tsawg!). Tom qab tag nrho, peb paub peb tus kheej zoo: thaum yav tsaus ntuj, nkees ntawm kev ua haujlwm, peb feem ntau yuav "tsis nco qab" los ntxuav lawv.
Qhov no yog qhov uas cov dab neeg yug los hais tias cov hniav tuaj yeem raug txhuam ib hnub ib zaug. Qhov tseem ceeb yog ua tib zoo.
Tsis txhob ua raws li tus thawj coj ntawm koj tus kheej tub nkeeg. Cov kws kho hniav thoob plaws lub ntiaj teb no muaj kev sib koom siab ntawm qhov teeb meem no: cov hniav yuav tsum txhuam ob zaug ib hnub, rau 2-3 feeb, tom qab (!) thawj zaug thiab zaum kawg.
Lus dab neeg 2. Qab zib ua rau cov hniav lwj
Kev tshaj tawm thoob ntiaj teb thiab txawm tias kws kho mob lawv tus kheej pom zoo kom noj cov khoom qab zib me me li sai tau. Qab zib rhuav tshem cov hniav enamel. Nws yuav zoo li qhov tseeb indisputable.
Tab sis nyob rau hauv kev muaj tiag: nws tsis yog qab zib nws tus kheej uas spoils cov hniav, tab sis lub sij hawm ntawm nws cov nyhuv rau lawv. Cov hniav lwj yog tshwm sim los ntawm acid secreted los ntawm cov kab mob, uas nyob rau hauv lem pub rau qabzib thiab carbohydrates. Thiab ntev dua cov kab mob "noj", lawv tso kua qaub ntau dua.
Yog li ntawd, cov khoom qab zib chocolate tsis muaj teeb meem rau peb cov hniav ntau dua li cov khoom qab zib li niaj zaus. Muab, tau kawg, tias tom qab noj nws, peb yaug peb lub qhov ncauj.
Lus dab neeg 3. Kev tshem tawm ntawm tartar ua rau kev tshem tawm cov hniav
Tag nrho cov txheej txheem kho hniav yog ntshai. Tej zaum qhov no yog qhov ua rau cov dab neeg hais tias txawm tias kev ua haujlwm yooj yim xws li ntxuav cov quav hniav puas tsuaj rau cov hniav, loosens lawv, ua rau microcracks ntawm cov enamel thiab, thaum kawg, ua rau lawv poob.
Qhov tseeb, calculus yog lub cev txawv teb chaws hauv lub qhov ncauj. Tsis tshem nws, tab sis nws tus kheej spoils cov hniav. Tsis tas li ntawd, niaj hnub kev kho hniav txoj kev tu hniav (xws li ultrasound) muaj kev nyab xeeb thiab tsis mob.
Lus dab neeg 4. Cov me nyuam tsis muaj dab tsi txhawj txog
Ntau tus niam txiv tsis ua raws li, lossis lawv ua tsis tau zoo, rau cov hniav ntawm lawv cov menyuam. Dab tsi rau? Tom qab tag nrho, cov no tsuas yog cov hniav me nyuam xwb - lawv yuav poob tawm lawm.
Cov menyuam yaus zoo li no loj hlob mus rau cov tub ntxhais hluas uas muaj cov hniav tsis zoo thiab tsis raug tom. Thiab lawv niam lawv txiv yuav tsum tau siv nyiaj ntau heev rau kev kho hniav thiab cov kws kho hniav.
Thiab tag nrho nws yuav tsim nyog paub tias qhov tsis muaj kev tu cev ntawm qhov ncauj ntawm tus menyuam ua rau caries thiab poob ntawm cov hniav ntxov ntxov. Cov "qhov" muaj cov hniav mus tas li. Yog li ntawd, kev hloov ntawm cov mis nyuj cov hniav nrog cov mus tas li tshwm sim unevenly, cov hniav loj hlob crooked.
Nco ntsoov: txij li 2, 5-3 xyoos, tus me nyuam nyob rau hauv kev saib xyuas ntawm cov niam txiv tuaj yeem txhuam hniav nrog cov tshuaj txhuam hniav tsis muaj fluoride. Los ntawm lub tsev kawm ntawv theem pib, tus menyuam yuav tsum tawm dag zog ntawm nws tus kheej thiab tswj kev huv ntawm qhov ncauj.
Lus dab neeg 5. Yog lawv tsis mob ces lawv noj qab nyob zoo
Kuv niam ntshai heev ntawm kws kho hniav. Nws haus cov tshuaj tua kab mob rau lub lis piam, tsis mloog tej lus ntuas, thiab tsuas yog mus cuag kws kho mob thaum nws ua tsis taus pa. Thiab alas, nws tsis nyob ib leeg ntawm no.
Peb feem coob tsuas yog mus ntsib kws kho hniav thaum peb cov hniav pib mob. Meanwhile, mob yog ib qho xwm txheej ceev. Qhov no yog kev quaj ntsuag ntawm tus hniav tuag. Kev hnov mob (xws li cov tshuaj tiv thaiv kub thiab txias) tshwm sim thaum cov kab mob tau nkag mus tob rau hauv thiab mus txog cov paj hlwb.
Tab sis tsis txhob maj cem koj tus kheej. Tsuas yog tus kws kho mob tuaj yeem txheeb xyuas qhov teeb meem thaum ntxov. Tsuas yog txuag lub sijhawm thiab nyiaj txiag rau kev tiv thaiv kev kuaj hniav. Rau cov hom phiaj no, nws raug nquahu kom mus ntsib kws kho hniav qhov chaw ua haujlwm tsawg kawg ib zaug txhua rau lub hlis.
Yog li tsawg prejudice, cov phooj ywg. Saib xyuas koj cov hniav thiab, koj yog leej twg, sib qhia kev luag ntxhi rau ib leeg.
