Fissure sealing

Nrog rau qhov kev siv ntawm cov tshuaj tiv thaiv kev ntsuas kom tiv thaiv kom txhob nws yog tsis txo ntau lub xyoo, qhov tseeb ntawm caries teeb meem thiab yuav tsum tau. Tswvyim qhia hais tias tus loj heev ntawm qhov ncauj kab mob hnub no lom tsis pub dhau 60-98% cov me nyuam yaus ntawm kaum ob xyoos. Nyob rau hauv cov ntaub ntawv no, lub ntsiab nce nyob rau hauv morbidity thiab ceev ceev kom vam meej ntawm tus kab mob yog cai nyob rau hauv ib nrab rau ob lub xyoos tom qab lub tsos ntawm mus tas li cov hniav, uas yog, ntog ntawm lub hnub nyoog ntawm rau los sis xya mus txog kaum ib thiab kaum peb xyoos. Qhov no lub sij hawm yog tseem yus muaj los ntawm tsis tiav mineralization ntawm cov hniav. Nrog rau qhov no, yuav luag 90% ntawm lub chaw muaj kab noj hniav rau cov zom chaw.

Tsis paub qab hau txha hniav laus yus siab porosity thiab ib tug tsawg dua ceev packing ntawm muaju, nws muaj me ntsis ftorapatitopodobnyh muaju tsawg soluble nyob rau hauv acids tshaj hydroxylapatites. Qhov no, nyob rau hauv lem, ua rau nws ntau lam tau lam ua rau acids.

Feem ntau, fissure sealing nyob rau hauv cov me nyuam tshwm sim nthawv, lawm. Yog li lawv nrhiav tau tuab heev mineralized tsim muaj ua kev teeb tsa. Cov formations muaj nyob rau ntawm lub hauv qab ntawm lub fissure. Qhov no cheeb tsam yog tus tsuas yog cheeb tsam ntawm concentration cawv centrifugal currents los ntawm nyob ze folds thiab hillocks. Yog li, kev sib khi fissures lawm nqa tawm vim tus txha hniav laus cawv.

Nyob rau hauv cov ntaub ntawv ntawm kev noj qab nyob teeb meem thiab muaj ntawm lub zos xwm ntawm muaj tej yam kev loj hlob ntawm caries, tshwm sim sealing tsis muab qhov chaw.

Fissures yog distinguished los ntawm hom tsev. Lawv yuav ua tau funnel-puab, poob-zoo li tus, lub khob hliav qab-puab. Muaj kuj polypoid.

Lub funnel-zoo li tus deepening anatomical hniav yog qhib ntau, ib tug zoo mineralization. Lawv tsis cim ncua zaub mov seem, uas yog vim free ntxuav ntawm lub qhov ncauj kua. Lub funnel-zoo li tus fissures xam tau tias yog kariesrezistentnymi.

Conical ua si nraum zoov anatomical kho hniav mineralized, feem ntau vim cov kua ntawm lub qhov ncauj kab noj hniav. Txawm li cas los, lawv yog tsim tej yam kev mob rau lub ncua sij hawm ntawm kab mob thiab cov zaub mov seem.

Mineralization polypoid droplet thiab depressions yog nqa tawm tsuas yog los ntawm cov kev kho hniav sis plawv hniav. Qhov no txoj kev muaj ib tug tsawg dua siv, yog li ntawd lawv nyob twj ywm ib tug ntev lub sij hawm txaus saline.

Sealing fissures nruab nrab adirevnymi obturation cov ntaub ntawv. Qhov no txoj kev yog aimed ntawm kev tsim ib tug teeb meem los mus tiv thaiv tej yam ntawm sab nraud cariogenic kab mob.

Sealing txhawb remineralization kho hniav enamel. Qhov no yog vim lub xam nrog ntawm lub ions ntawm active cov khoom siv.

Nws yuav tsum tau muab sau tseg tias tactics sealing noj qab nyob zoo hniav txha hniav laus maturation yog xaiv nyob rau hauv raws li cov ntaub ntawv nyob rau hauv lawv cov thawj theem ntawm mineralization (NYM).

Fissure sealing yog ua mas nyob rau hauv thawj lub hlis ntawm qhov uas. Qhov tseeb feem ntau ua rau kev txhawj xeeb. Lawv yog txuam nrog rau cov tshwm sim ntawm teeb meem thaum lub sij hawm ripening ntawm cov zog ntaub so ntswg. Qhov no yuav ua puv thawm los ntawm cov nyob rau sealant uas tiv thaiv lub nkag mus ntawm qhov ncauj kua. Txawm li cas los, feem ntau niaj hnub kws tshawb fawb pom zoo hais tias lub mineralization feem ntau ib nrab kev cuam tshuam ntawm txha hniav laus maturation yog tsis cuam tshuam.

Ntxiv mus, lub ntsiab muaj nyob rau hauv cov qaub ncaug, muaj peev xwm sawv ntawm dawb do diffuse mus rau hauv thiab cov los ntawm cov txheej cov ntaub ntawv uas ntug. Qhov no, nyob rau hauv lem, muab ib tug physiological theem ntawm metabolic dab nyob rau hauv cov ntaub so ntswg nyob rau hauv lub zog kho hniav sealant, thaum tiv thaiv allergic ntawm loj protein molecules.
