Kev hnov mob ntawm cov hniav feem ntau yog ua rau muaj kev tsis zoo xws li tsis muaj kab mob xws li tsis txawv txav, yaj yaus, zoo li tawg, thiab lwm yam. Qee zaum tib neeg tsim qhov teeb meem no rau lawv tus kheej, sim ua kom lawv cov hniav tawg nrog cov tshuaj txhuam hniav thiab cov tawv txhuam hniav. Qhov no, cov hniav pib sai li sai tau rau cov stimuli sab nraud.
Kev ntsuas tus kheej tsis zoo hauv lub qhov ncauj, qhov tseeb, tsis yog kev kho mob rau cov mob tsis zoo, tab sis pab kom txo tau lawv qhov kev mob, uas ua rau cov neeg mob txhawj xeeb - feem ntau ntawm cov hniav. Thaum mob hnyav, nws ua rau nws tus kheej tshwm sim nyob rau hauv daim ntawv ntawm lub zog muaj zog heev rau hauv cov hniav (tshwj xeeb tshaj yog lub forelegs), uas ua rau cov huab cua uas nkag rau hauv qhov ncauj kab noj hniav. Thaum zoo li no, nrog rau kev kho mob tsim nyog, koj yuav tsum xaiv cov khoom siv lub qhov ncauj zoo.
Kom tsis txhob raug mob ntxiv rau cov kab mob uas twb nkag tau lawm, koj yuav tsum siv tus txhuam hniav nrog ib lub caj dab muag muag. Cov tshuaj txhuam hniav uas tsis huv yog tsis haum - lawv txaus txhuam thiab tsis muaj cov khoom uas txo cov hniav. Thiab txawm tsis yog tag nrho kho thiab tiv thaiv pastes yog haum rau cov neeg zoo li no.
Nrog rau kev muaj zog ntawm cov hniav uas muaj cov pob txha tsis muaj mob ntawm cov tawv nqaij, koj siv tsis tau cov tshuaj uas muaj:
aluminium compounds raws li kev tivthaiv kabmob nrawm (heev txhuam);
chalk thiab silicon (abrasive);
sib txuas ntawm silicon thiab dej qab-bicarbonate (abrasive);
ntsev cov tshuaj txhuam hniav (abrasive).
Nws yuav tsum to taub hais tias qhov ntau zog ntawm cov khoom qub uas tau muab teev tseg yog pom tib yam nkaus xwb hauv kev mob plawv. Yog tias cov hniav zoo, muaj cov tshuaj txhuam hniav zoo huv thiab tsis tuaj yeem ua rau raug mob.
Thaum cov tshuaj hnyav dhau los yog pom zoo siv cov tshuaj txhuam hniav uas muaj cov kabmob uas muaj cov kabmob uas muaj cov kabmob "fluoride", uas ua rau cov duab tiv thaiv ntev ntawm cov hniav. Optimal kev xaiv yog ib txoj kev kho mob thiab tiv thaiv tshuaj tiv thaiv nrog tshuaj fluoride. Txawm li cas los, nws cov hauj lwm zoo tsis yog tshwm sim sai sai. Xws li ib qho muab tshuaj txhuam tau txo cov khoom vim yog cov ntsiab lus ntawm cov khoom me me ntawm silicon tebchaw. Lub poov tshuaj ions uas muaj nyob rau hauv qhov muab tshuaj txhuam, nkag mus rau hauv cov hniav ntawm cov hniav, khom rau ntawm qhov muag ntawm cov nqaij ntawm cov ntaub so ntswg thiab thaiv qhov kev xaav ntawm sab nrauv. Hydroxyapatite thiab tricalcium phosphate, uas yog ib feem ntawm qhov muab tshuaj txhuam, kuj thaiv kev nkag mus rau hlwb hlwb kho hlwb. Cov tshuaj yeeb dej caw, cov khoom siv sib xyaw ua ke ntawm cov ntaub so ntswg ntawm cov hniav, muaj peev xwm kho lub siab osmotic hauv lawv thiab txo cov nyhuv ntawm cov hlab ntsha. Cov nyhuv ntawm kev siv xws li muab tshuaj yog los ntawm hnub tim 4-9.
Qee tus neeg pib siv cov hniav elixirs nrog kev muaj zog ntawm cov hniav. Koj tsis tas yuav ua li no. Lawv muaj cawv (tsis pub tsawg tshaj 30%), nws khaus lub voos ntawm cov hniav. Tsis txhob haum thiab ntxuav yaug. Cov kws kho mob pom zoo kom siv cov tshuaj tsis yog dej caw thiab cov tshuaj tua kab mob nrog cov tshuaj fluoride.
Yog hais tias, nrog rau cov kab mob ntawm cov hniav, qhov chaw ntawm cov nqaij mos (ncig thiab tuav cov hniav) yog kuaj pom, tom qab siv lub tshuab ntxuav hniav ntawm lub qhov ncauj thiab tshem cov qe ntshauv ntawm cov pos hniav (ua los ntawm ib tus kws kho mob), ntses thiab tonics rau cov pos hniav cov pos hniav tsis siv).
Cov tshuaj txhuam hniav ua rau lub qhov muag tsis pom kev ntawm cov hniav thiab tsis siv raws li xav tau. Kev siv hlua yuav tsum tau siv tas li, tab sis raws li kev tiv thaiv ntawm qhov mob ntawm cov hniav, lawv tsis muaj dab tsi.
Ib tug neeg yuav nug: Kuv puas siv tau tus txhuam hniav fais fab? Cia peb xam nws. Feem ntau cov yuav tau ua, qhov no yog ua li cas nrog kev sib nkag siab ntawm cov hniav tsis tsim nyog nws. Ua ntej, tu lub taub hau hauv nws muaj qhov hnyav nruab nrab ntawm cov pob txha, rau cov kab mob sib kis tau tus mob no twb yog ib qho raug rho tawm. Secondly, nozzles rau hluav taws xob txhuam tuaj nyob rau hauv ob daim duab - puag ncig thiab rectangular. Tu cov pob txha caj npab nrog cov kab rov tav (tsis txais tos los ntawm cov kws kho hniav) yuav ua rau lub zog ntawm cov tawv nqaij ntawm cov hniav, yog li qhov kev xaiv no yuav tsum muab pov tseg. Fais txhuam nrog lub taub hau, nrog lub siab ntshaw, nws yog permissible - nws ua rau cov lus tsa suab rov qab los ua ib qho kev sib txhuam ntawm tus txhuam hniav.
Cov ntawv txhuam hniav thiab cov neeg me me (ntawm cov tufts ntawm bristles) txhuam hniav tuaj yeem yog ib qho kev pabcuam zoo, tshwj xeeb tshaj yog thaum muaj super-siab rhiab heev, thiab siv los kho lub cev tsis zoo ntawm cov ntaub so ntswg. Ntsuas dua nrog txhuam nrog ib hom kab bristle. Lawv kuj tuaj yeem siv rau kev siv cov npe ntawm pastes nrog hydroxyapatite nyob rau thaj tsam tsis zoo.
Irrigators, tshwj xeeb tshaj yog nyob rau hauv hom "da dej", txhawb kev atraumatic, tsis khaus, tsis mob tsis tu cov hniav ntawm cov khib nyiab thiab cov quav hniav. Koj tuaj yeem siv cov zom zom plaub uas tsis ntim cov khoom xyaw thiab cov khoom ntub, tab sis ntev ntev tom qab noj mov.
