Nrog rau qhov sib txawv ntawm kev saib xyuas qhov ncauj ntau dua, kev kho hniav txhuam hniav, ua cov cuab yeej tseem ceeb rau kev tshem cov quav hniav ntawm cov hniav, tau hloov mus rau ntau hom vim qhov sib txawv ntawm cov khoom, cov duab, thiab kev siv cov xwm txheej. Cov hom no ua tau raws li qhov sib txawv ntawm qhov ncauj thiab cov neeg siv tus cwj pwm, muab cov kev daws teeb meem rau kev saib xyuas.
Raws li cov khoom siv, cov khoom siv kho hniav tseem tuaj yeem muab faib ua ob pawg: nylon thiab polytetrafluoroethylene (PTFE). Nylon hniav txhuam hniav yog tsim los ntawm ntau cov hlua ntawm cov fibers zoo twisted ua ke, sib txuas yooj yooj yim thiab kev sib txhuam kom zoo tshem cov quav hniav ntawm cov hniav. Qee cov khoom yog waxed los txo cov kev sib txhuam, ua rau lawv haum rau cov pos hniav rhiab heev los yog nruj nris ntawm cov hniav. PTFE hniav txhuam hniav, ntawm qhov tod tes, muaj cov qauv monofilament, du nto, thiab tsis tshua muaj kev sib cais lossis tawg. Nws muaj kev tiv thaiv tsawg dua thaum lub sij hawm ntxuav, ua rau nws tshwj xeeb tshaj yog haum rau qhov dav dav ntawm cov hniav los yog ib puag ncig kev kho dua tshiab (xws li cov yas thiab cov hlua khi), txo cov kev xav ntawm lub cev txawv teb chaws thiab kev tu tawv nqaij - mus rau - mus txog thaj chaw.
Raws li cov qauv tsim, kev kho hniav tuaj yeem muab faib ua ob pawg: yob- hom thiab ua ntej- tsim. Yob- hom tshuaj txhuam hniav yog qhov ntev thiab qhov txhab nyob ib puag ncig ib puag ncig, tso cai rau txiav mus rau qhov ntev raws li xav tau. Nws muaj qhov yooj yooj yim thiab cov khoom siv qis, ua rau nws tsim nyog rau cov neeg siv uas muaj nuj nqis kev lag luam thiab kev ywj pheej. Ua ntej- zoo li tus hniav txhuam hniav, feem ntau ib tus zuj zus ntim rau hauv "Y" los yog hneev nti, muaj ib qho ruaj khov kawg thiab lwm yam dawb, ua raws li tus hniav nto yam tsis muaj phau ntawv shaping. Qhov no yog cov neeg siv ntau dua -tus phooj ywg rau cov neeg pib tshiab lossis cov neeg taug kev, txawm hais tias tus nqi ntawm ib qho kev siv yog me ntsis siab dua, nws txhim kho kev yooj yim ntawm kev siv thiab kev nyiam huv.
Kev kho hniav tshwj xeeb txuas ntxiv nthuav dav nws cov ntawv thov. Cov tshuaj fluoride muaj cov tshuaj fluoride hauv nws cov fibers, tso tawm cov khoom tiv thaiv kab mob thaum ntxuav thiab ntxiv dag zog rau cov kua qaub tiv thaiv ntawm qhov chaw interdental, ua rau nws tsim nyog rau cov neeg muaj kev pheej hmoo siab -. Expandable dental floss expands me ntsis raws li kev sib cuag nrog cov qaub ncaug, nruj nreem kaw qhov chaw tsis tu ncua interdental thiab txhim kho kev tu cov kev pab cuam ntawm complex pits thiab fissures. Tsis tas li ntawd, cov khoom siv tshuaj txhuam hniav tsim los rau cov neeg mob orthodontic tso cai rau cov hlua khi rau hauv qhov khoob ntawm cov hlua khi thiab cov xov hlau, daws cov teeb meem kev tu vaj tse uas cov tsoos tsho tsis tuaj yeem ncav cuag.
Kev faib cov tshuaj txhuam hniav yog qhov tseem ceeb ntawm "kev thov-tsav" kev hloov pauv ntawm thev naus laus zis. Los ntawm cov ntaub ntawv thiab cov duab mus rau qhov yooj yim tu thiab txhim khu kev ua haujlwm, ntau hom kev kho hniav ua kom muaj kev sib txawv ntawm qhov ncauj los ntawm lawv cov yam ntxwv tshwj xeeb -txawm tias koj muaj cov pos hniav tsis yooj yim, qhov khoob ntawm cov hniav, lossis tab tom kho tshwj xeeb, koj tuaj yeem nrhiav cov cuab yeej tsim nyog. Kev nkag siab txog cov txheej txheem kev faib tawm pab cov koom haum tshaj lij qhia cov neeg siv kev paub txog kev xaiv, tso cai rau kev kho hniav kom hloov los ntawm "cov cuab yeej dav" mus rau hauv tus neeg nqa khoom tseem ceeb ntawm "kev kho tus kheej," thiab txhawb kev ntxuav qhov ncauj los ntawm "kev pab them nqi" mus rau "precision thiab efficiency."
