Hauv ncaj qha kev kho hniav, tus kws kho hniav siv khoom hu ua cov tshuaj sib xyaw los tsim cov txhaws lossis nqus (hom loj dua ntawm kev ntim). Cov txheej txheem ua tiav thaum lub sijhawm mus ntsib chaw ua haujlwm. Nrog tsis ncaj kev kho hniav, tus kws kho hniav siv cov pwm ntawm cov hniav lwj. Cov pwm no raug xa mus rau ib lub chaw kuaj ntshav, uas tsim cov khoom ntim lossis ntim rau hauv.
Ua qhov no hauv kev txiav txim siab, qhov sib txawv ntawm kev kho ncaj qha thiab tsis ncaj qha yog dab tsi?
Ncaj kho hniav kho feem ntau yog siv thaum tus neeg mob cov hniav (los yog cov hniav) tsis zoo thiab noj qab nyob zoo txaus nyob. Tsis ncaj Cov txheej txheem kho hniav feem ntau tsim nyog rau cov neeg mob uas muaj kev puas tsuaj ntau dua thiab cov hniav lwj uas feem ntau ua rau cov hniav ploj.
Ib sab saum toj no, dab tsi yog cov lus nug rov kho ncaj qha? EXAMPLES: Cov yas yas, Cov Khoom Siv Ceramic, Cov plooj (porcelain), inlays, onlays, veneers. Ncaj Ncees . ncaj qha mus rau ntawm tus hniav thiab nws tuaj yeem carved, yoog, thiab tiav. EXAMPLES: Amalgam, Composite Resins, Ionomers iav, cov khoom siv hniav ntxuav hniav dawb, thiab cov khoom siv kho ib ntus.
Yog li ntawd, dab tsi yog direct restorative?
Cov ntaub ntawv kho ncaj qha . Kev kho ncaj qha yog cov uas tau muab tso ncaj qha rau hauv kab noj hniav ntawm tus hniav, thiab zoo li tus kom haum. Chemistry ntawm qhov teeb meem tshwm sim rau direct restorative cov ntaub ntawv tau tsim los kom muaj kev sib raug zoo dua qub.
Dab tsi yog kev kho kom ncaj qha hauv kev kho hniav?
Indirect restorations yog kho uas yog tsim sab nraum lub qhov ncauj. Indirect restorations muaj xws li crowns, inlays thiab onlays. Feem ntau, indirect restorations yuav tsum tau mus ntsib ob lossis ntau dua rau qhov chaw. Thaum mus ntsib thawj zaug, tus kws kho hniav npaj cov hniav thiab ua rau muaj kev xav ntawm thaj tsam kom rov zoo.

Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm cov khoom sib tsoo thiab qhov kov zoo?
Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm 'crude' kov thiab 'nplua' kov qhov hnov? Nyuaj kov yog hais txog kev nkag siab los ntawm kev txhawb nqa ntawm cov neeg txais khoom ntawm qhov tsis nkag siab nrog cov teb loj. Hauv kev sib piv, kev kov zoo yog hais txog cov neeg txais khoom ntawm kev nkag siab siab nrog cov chaw txais me me
Dab tsi yog qhov txawv ntawm qhov ncaj thiab tsis ncaj Elisa?
Hauv qhov ncaj qha elisa tsuas yog siv ib qho tshuaj tiv thaiv kab mob - qhov tshuaj tiv thaiv ib leeg yog sib txuas ncaj qha mus rau kev kuaj pom enzyme. Elisa tsis ncaj qha xav tau ob lub tshuaj tiv thaiv kab mob-thawj cov tshuaj tiv thaiv kab mob thiab ib qho enzyme txuas nrog cov tshuaj tiv thaiv kab mob thib ob uas ntxiv rau thawj cov tshuaj tiv thaiv kab mob
Qhov sib txawv ntawm bilirubin ncaj qha thiab bilirubin ncaj qha yog dab tsi?
Abb. Nco tseg: Conjugated bilirubin feem ntau tsis raug hu ua 'bilirubin ncaj qha' thiab unconjugated bilirubin tsis raug hu ua 'indirect bilirubin'. Ncaj thiab ncaj qha hais txog qhov sib xyaw ntsuas lossis kuaj pom hauv kev daws teeb meem. Indirect bilirubin yog rog-soluble thiab ncaj qha bilirubin yog dej-soluble
Qhov txawv ntawm Elisa ncaj qha thiab tsis ncaj Elisa yog dab tsi?
Hauv elisa ncaj qha tsuas yog siv ib qho tshuaj tiv thaiv kab mob - qhov no ib qho tshuaj tiv thaiv kab mob sib txuas ncaj qha mus rau kev tshawb nrhiav enzyme. Elisa tsis ncaj qha xav tau ob lub tshuaj tiv thaiv kab mob-thawj cov tshuaj tiv thaiv kab mob thiab ib qho enzyme txuas nrog cov tshuaj tiv thaiv kab mob thib ob uas ntxiv rau thawj cov tshuaj tiv thaiv kab mob
Dab tsi yog qhov txawv ntawm kev kuaj tsis ncaj thiab ncaj qha tiv thaiv kab mob?
Direct IF siv tib cov tshuaj tiv thaiv kab mob tiv thaiv lub hom phiaj ntawm kev txaus siab. Thawj cov tshuaj tiv thaiv yog ncaj qha conjugated rau fluorophore. Indirect IF siv ob lub tshuaj tiv thaiv kab mob. Thawj cov tshuaj tiv thaiv yog unconjugated thiab fluorophore-conjugated Secondary antibody qhia tawm tsam thawj cov tshuaj tiv thaiv yog siv los tshawb nrhiav
