Ib qho ntawm feem ntau ntawm cov niam txiv yog qhov tsis kho ntawm tus menyuam cov hniav. Me nyuam cov hniav yuav kho tau thiab xav tau thiab nyob rau hauv cov kev kho mob uas lawv xav tau ntau tshaj cov laus.
Dab tsi yog qhov xav tau cov tshuaj fluoridation ntawm cov hniav hauv cov me nyuam?
Txoj kev tso cai no tau tso cai ntev ntev los tiv thaiv kev tiv thaiv kab mob hniav thiab lwm yam teeb meem. Thaum cov tshuaj fluorinating ntawm cov hniav, ib txheej tshwj xeeb yog tsim rau saum npoo, uas ua tau zoo tshaj qhov muaj zog ntawm tus hniav thiab tsis pub calcium uas yuav ntxuav tawm ntawm cov ntaub so ntswg kom sai.
Cov txheej txheem ntawm fluoridation los yog silvering ntawm cov mis nyuj cov hniav yog qhia rau cov me nyuam uas muaj cov kab mob. Qhov no tso cai rau kev tiv thaiv kom tsis txhob muaj kev tiv thaiv kab mob ntawm cov kua nplaum los ntawm fluorine, calcium thiab phosphorus nyob rau hauv cov lus ntawm ib qho tshwj xeeb muab tshuaj txhuam.
Hom tshuaj fluoridation hauv cov menyuam yaus
Muaj ob txoj hauv kev los ua txoj haujlwm no.
- Thawj txoj kev hu ua yooj yim. Ua ntej, tus kws kho mob ua tus cam ntawm tus neeg mob cov hniav. Tom qab qhov no, cov pwm puv no muaj cov tshuaj fluoride thiab muab tso rau hauv cov hniav. Qhov thib ob hom yog siv ntawm ib tug tshwj xeeb lacquer. Qhov kev xaiv thib ob yog tsis tshua muaj txiaj ntsig zoo, vim tias cov tshuaj calcium fluoride tsis tau tso rau hauv cov khaubncaws sab nraud povtseg ntawm tus txha nqaj, yog li ntawd nws yog txawb tawm tom qab txhua tus txhuam hniav.
- Txoj kev thib ob yog kev sib sib zog nqus fluoridation ntawm cov hniav hauv cov menyuam yaus. Qhov no, fluorine penetrates tob rau hauv cov khaub thuas cev thiab muaj tuas muaj, ua tus hniav kaum zaus muaj zog. Kev sib fluoro fluoridation ntawm cov mis nyuj yog nqa tawm hauv ntau theem. Ua ntej, tus kws kho mob nrog cov cuab yeej tshwj xeeb ntxuav cov hniav thiab cov chaw nruab nrab thiab ua rau lawv muaj cua txias. Tom qab ntawd cov hniav yog kho nrog molochkom hydroxide ntawm tooj liab thiab calcium, rinsed nrog dej. Nrog kev sib fluoridation ntawm cov mis nyuj, cov concentration ntawm ions uas ua los ntawm calcium fluoride crystals yog tsib zaug siab dua cov concentration tom qab cov tshuaj fluorination yooj yim.
Qhov tshwm sim ntawm cov tshuaj fluoridation ntawm cov mis nyuj
Tom qab cov txheej txheem no, lub qhov txhab ntawm tus hniav txhuam hniav yog nce los ntawm ib yam ntawm kaum, yog li qhov kev pheej hmoo ntawm hniav lwj lossis hniav rhiab heev txo. Cov txheej txheem tiv thaiv kev tiv thaiv yog tsim rau 6 lub hlis. Tus neeg mob me tuaj ntsib tus kws kho mob ib zaug xwb. Vim li ntawd, peb muaj cov nram qab no:
- Yog hais tias tus me nyuam muaj lub foob, ces lub sijhawm nws cov kev pab yuav raug ntev mus ntev;
- txo cov ncauj lus qis dua;
- tus mob ntawm daim tawv nqaij ntawm qhov ncauj thiab pos hniav normalize;
- Yog hais tias tus me nyuam muaj tus kab mob hypersensitivity, ces nws maj mam kis tau.
