Nyob rau hauv cov evolution ntawm cov cuab yeej saib xyuas qhov ncauj, kev kho hniav txhuam hniav, raws li ib tug tshiab daim ntawv ntawm cov hniav ntxuav hniav dawb, tau maj mam dhau los ua ib qho kev xaiv tseem ceeb rau kev tu lub qhov ncauj txhua hnub vim lawv cov qauv tsim thiab yooj yim ntawm kev siv. Lawv cov organically sib xyaw ua ke cov tshuaj ntxuav hniav nyias nyias ntawm cov hniav txhuam hniav nrog ib lub tes tuav, khaws cov kev tu huv huv ntawm cov hniav txhuam hniav hauv thaj chaw nyuaj kom ncav cuag ntawm cov hniav thaum txo qis qhov cuam tshuam rau kev nkag, ua kom pom tseeb tus nqi hauv kev saib xyuas thiab siv hauv tsev.
Cov txheej txheem tseem ceeb ntawm kev kho hniav txhuam hniav muaj ob ntu: ib ntus thiab cov hlua khi. Tus kov feem ntau nta ib qho ergonomic nkhaus lossis ncaj tsim nrog tsis yog - plam nto kom yooj yim tuav thiab siv zog. Cov floss ntu feem ntau yog ua los ntawm cov nylon stranded los yog PTFE monofilament, nrog rau qee cov khoom uas muaj cov wax txheej rau kev txhim kho smoothness. Qhov ntev feem ntau tswj tau ntawm 4-5 cm, nrog rau ua ntej- teeb "C" zoo lossis lub tiaj tiaj uas tuaj yeem siv ncaj qha rau ntawm cov hniav yam tsis muaj phau ntawv winding lossis shaping. Qhov kev tsim no ua kom yooj yim rau cov txheej txheem ntau- kauj ruam ntawm "txiav- kho- kev ua haujlwm" cov hniav txhuam hniav rau hauv ib qho, tsis tu ncua " tuav- zawv zawg ". Qhov no yog tshwj xeeb tshaj yog haum rau cov neeg uas tsis muaj tes dexterity (xws li cov menyuam yaus thiab cov neeg laus) los yog thawj zaug flossers, txhim kho kev nkag tau zoo thiab ua raws.
Nyob rau hauv cov nqe lus ntawm kev ua haujlwm txuas ntxiv, cov khoom siv txhuam hniav tuav cov ntsiab lus tu tib yam li cov hniav txhuam hniav ib txwm siv - siv cov fiber ntau zoo kom nkag mus tob rau hauv qhov khoob ntawm cov hniav thiab cov gingival sulcus, tshem tawm cov khoom noj khoom haus, tshem tawm cov quav hniav thiab biofilm, thiab ntxuav cov qhov muag tsis pom kev uas txhuam hniav tsis tuaj yeem ncav cuag. Kev soj ntsuam kev soj ntsuam pom tau hais tias kev tiv thaiv kev tiv thaiv ntawm cov tshuaj txhuam hniav ntawm cov kab mob sib kis yog piv rau cov yob- hom tshuaj txhuam hniav thaum siv kom raug, zoo txo cov quav hniav ntawm cov hniav thiab ncua kev tsim cov tartar thiab gingival o tuaj. Nws qhov sib txawv ntawm qhov zoo yog nyob ntawm nws qhov kev hloov pauv: ib tus zuj zus ntim cov hlua khi yog ib qho yooj yim rau nqa, haum rau kev mus ncig, siv chaw ua haujlwm, thiab lwm yam tawm ntawm - ntawm - cov xwm txheej hauv tsev; qhov kev txhawb nqa kov txo cov kev txhawj xeeb ntawm kev nyiam huv uas cuam tshuam nrog kev sib cuag ntiv tes ncaj qha nrog cov hlua khi thiab zam cov teeb meem xws li xoob fibers lossis kev tswj kav ntev uas tuaj yeem tshwm sim nrog yob- hom tshuaj txhuam hniav.
Nws yog ib qho tsim nyog sau cia tias qhov kev ua tau zoo ntawm kev kho hniav txhuam hniav yog ze ze rau cov khoom tsim cov ntsiab lus. High- cov khoom zoo muaj cov ntaub qhwv nrog cov nro nruab nrab, ua kom muaj kev sib raug zoo thaum ntxuav thaum tiv thaiv kev tawg lossis cov pos hniav puas los ntawm kev quab yuam ntau dhau. Qhov kov ntev thiab curvature yuav tsum ua raws li cov cuab yeej siv tes, txo qhov qaug zog thaum siv ntev. Qee lub npe muaj cov ntaub nplaum tuab dua, cov tshuaj fluoride, los yog cov txhuam hniav sib xyaw nrog cov txhuam me me los hais txog cov kev xav tau tshwj xeeb, ntxiv dag zog rau lawv lub peev xwm ntxuav hauv qhov chaw dav dav, nyob ib puag ncig kev kho dua tshiab, lossis cov qhov khoob hauv qhov ncauj, ua kom pom cov cuab yeej teb rau cov ncauj lus tshwj xeeb.
Txawm hais tias kev siv cov hlua khi hniav muaj cov txiaj ntsig zoo hauv kev siv yooj yim, lawv qhov kev txhawb nqa tseem qhia txog qhov tseem ceeb ntawm kev siv kom zoo: cov hlua khi yuav tsum tau qhwv ib ncig ntawm cov hniav hauv qhov "C" thiab maj mam glided nce thiab nqis raws cov pos hniav, tsis txhob quab yuam txoj kab rov tav; nws yuav tsum muab pov tseg tam sim ntawd tom qab txhua qhov kev siv los tiv thaiv kev sib kis -. Raws li ib qho yooj yim txuas ntawm cov tshuaj txhuam hniav ib txwm siv, kev kho hniav txhuam hniav tsis tau hloov cov ntsiab lus tseem ceeb ntawm kev huv ntawm qhov ncauj- ua tiav cov quav hniav los ntawm kev cuam tshuam meej hauv kev nyuaj- mus rau - mus txog thaj chaw nruab nrab ntawm cov hniav -tab sis txo cov kev cuam tshuam rau kev siv cov cuab yeej siv kho mob ntau dua rau txoj hauv kev zoo tshaj plaws rau kev siv cov cuab yeej kho mob. kev nyiam huv ntawm cov pej xeem.
