Kungani i-methylene blue ishintsha umbala womchamo, wolimi nowamazinyo
I-methylene blue ingashiya umbala lapho ithinta khona umlomo futhi ingafaka umbala emchamweni ngemva kokungena emzimbeni. Lezi yizinqubo ezihlukene. Ulimi oluluhlaza sasibhakabhaka lukutshela ngokuyinhloko ukuthi udayi uthinte indawo ethile. Umchamo oluhlaza sasibhakabhaka oxubene noluhlaza satshani ungabonisa udayi ophuma ngomgudu womchamo. Akukho kulokhu okulinganisa umthamo owusizo, ukumuncwa emzimbeni, ukusebenza, ubumsulwa noma ukuphepha.
Ungathathi i-methylene blue eyengeziwe ngoba umchamo wakho ungakashintshi ube luhlaza sasibhakabhaka. Awukho umbala womchamo okuqinisekiswe ukuthi kufanele kufinyelelwe kuwo ekhaya. Izimpawu nezimo zokuchayeka zibaluleke kakhulu kunokufanisa umbala nesithombe.
Kungani umchamo ungabukeka uluhlaza satshani kunokuba ube luhlaza sasibhakabhaka
Ulwazi lokunikeza i-PROVAYBLUE efakwa emthanjeni luthi cishe u-40% we-methylene blue ukhishwa emchamweni ungashintshile. Leli nani lichaza indlela umuthi ocutshungulwa ngayo emzimbeni; aliyona indlela yokubala umthamo ophuzwa ngomlomo ngokubheka amanzi asendishini yendlu yangasese.
Umchamo usuvele unezinto eziwufaka umbala ophuzi. Udayi oluhlaza sasibhakabhaka phezu kwalowo mbala ophuzi ungadala ukubukeka okuluhlaza satshani noma okuluhlaza sasibhakabhaka okuxubene noluhlaza satshani. Ukuhlanjululwa nezimo zokubuka nakho kuthinta lokho okubonayo: uketshezi olusepayipini elincane, olusesitsheni esijulile sokuqoqa, kanye namanzi endlu yangasese akudingeki kubukeke kufana.
Embikweni kaKoratala noLeghrouz wesigameko sangemva kokuhlinzwa, i-methylene blue yanikezwa ngepayipi elidlula ekhaleni liye esiswini ukuze kuhlolwe isisu esasikulungisiwe. Umchamo wesiguli waba luhlaza satshani, umbala wayesufiphala phakathi kwezinsuku ezinhlanu. Lokhu kubhala indlela isigameko esisodwa esenzeka ngayo emtholampilo, hhayi umnqamulajuqu okufanele umchamo wawo wonke umuntu ubuyele ngawo embala wawo wangaphambili.
Kuthiwani uma i-methylene blue ingawenzi umchamo ube luhlaza sasibhakabhaka?
Ukubuka nje ngeke kwehlukanise izincazelo eziningana ezingaba khona: isikhathi okubukwe ngaso, ukuhlanjululwa komchamo, inani lento enemibala ekhona, kanye nesimo sayo samakhemikhali. I-methylene blue ingaguqulwa ngokusabela kokwamukela ama-electron ibe yi-leucomethylene blue engenambala; ucwaningo lokuhlaziywa komchamo womuntu lwathola lesi simo esiguquliwe emchamweni ngemva kokunikezwa ngomlomo. Ikhemistri ye-methylene blue ne-leucomethylene blue isiza ukuchaza ukuthi kungani umbala oluhlaza sasibhakabhaka obonakalayo nokuba khona kwale nhlanganisela kungeyona imiqondo engasetshenziswa esikhundleni somunye.
Ukungawuboni umbala oluhlaza sasibhakabhaka akuqinisekisi ukungamuncwa emzimbeni, umkhiqizo mbumbulu, ukucutshungulwa okusheshayo emzimbeni, noma isidingo sokuchayeka okwengeziwe. Ukubona umbala oluhlaza sasibhakabhaka oqinile akuqinisekisi ukumuncwa kahle noma ukwelashwa okusebenzayo. Akukho kulokhu okuveza ukuthi umkhiqizo unokungcola okungafuneki yini.
Uma kunombuzo mayelana nokuthi into iyini noma ukugxila kwayo, sebenzisa imibhalo yokuhlaziywa ehambisana neqoqo lomkhiqizo. Uma kunombuzo wokwelashwa, sebenzisa ukuqapha kwezokwelapha okunqunyiwe. Umuntu oqhathanisa imikhiqizo emibili ngombala womchamo ushintshe izinto eziningi ngesikhathi esisodwa, okuhlanganisa isikhathi nokuhlanjululwa, ngaphandle kokulinganisa noma yimuphi umkhiqizo.
Kungani ulimi namazinyo kungaba namabala
Uketshezi oluthinta umlomo lungashiya udayi olimini nasezindaweni zamazinyo. Ukusabalala kwawo kungase kungalingani ngoba ulimi alubushelelezi futhi lungagcina izinsalela. Ucwaningo lokufaka umbala ezilondeni zomlomo luchaza ngokukhethekile ukuqoqana kukadayi oweqile engxenyeni engaphezulu yolimi nasemifantwini yezinsini. Lolo cwaningo lwahlola indlela yokuxilonga esetshenziswa emtholampilo. Alwenzi indlela ibala elivele nje elibukeka ngayo ibe ukuhlolwa kwasekhaya kwesifo somlomo.
Ukuhlanza umlomo ngendlela evamile nemnene kuyimpendulo efanele ebala elingaphezulu elingenabuhlungu. Ungalukhuhli ngamandla ulimi noma usebenzise izisusi zamabala zasendlini, izincibilikisi noma i-bleach emlonyeni. Ibala eliqhubekayo naphezu kokuhlanza okuvamile, noma ushintsho oluhambisana nobuhlungu, izilonda noma ukuvuvukala, kudinga ukuhlolwa udokotela wamazinyo noma omunye udokotela. Asikho isithembiso esisekelwe ebufakazini sokuthi wonke amabala ayanyamalala phakathi kwenani elithile lamahora.
Ingabe i-methylene blue ingafaka amabala kuma-veneer, kuma-crown noma ezintweni zokugcwalisa amazinyo?
Ingafaka amabala ezintweni ezisetshenziswa emazinyweni, kodwa elithi “ama-veneer” alichazi into eyodwa. I-veneer eyenziwe nge-composite, into yokulungisa izinyo eyenziwe nge-ceramic, kanye nento enamathelisayo ezungeze indawo elungisiwe kuyizindawo ezihlukene. Ubufakazi obuvela kwenye ngeke buqinisekise indlela zonke ezinye eziziphatha ngayo.
Ocwaningweni lwaselabhorethri lwama-resin e-composite ayisithupha, abacwaningi baqhathanisa izindawo ezigugile nezingagugile ngemva kokuchayeka ku-0.5% we-methylene blue. Izilinganiso ezenziwe nge-spectrophotometry zabonisa amabala, anomehluko phakathi kwezinto ezisetshenzisiwe nezimo zezindawo zazo. Lezi kwakungamasampula aselabhorethri, hhayi iziguli eziphuza umkhiqizo othengiselwa abathengi. Okutholakele kusekela ukubheka amabala ezintweni zokulungisa amazinyo njengento ebalulekile; akubikezeli ukuthi i-veneer ethile izoba nebala elingasuki yini.
Uma into yokulungisa izinyo ishintsha umbala, nikeza udokotela wakho wamazinyo ilebula yomkhiqizo, isikhathi sokuchayeka, nemininingwane yento esetshenzisiwe uma yaziwa. Ungathathi amakhemikhali okuhlanza imigudu yezimpande zamazinyo asetshenziswe ocwaningweni lwamazinyo uwasebenzise ekhaya. Ukuhlanza izinto zasendlini kuyisihloko esihlukile esichazwe kokuthi ukususa amabala e-methylene blue ezindaweni nasezindwangwini.
Ukuqhathanisa ngezithombe okunomkhawulo obalulekile
Lezi zithombe ezishicilelwe zibonisa isigameko esifanayo esibikiwe sezokwelapha ezimweni ezimbili zokubuka. Zibonisa ukuthi kungani umbala obonakalayo udinga umlando wokuchayeka nokuhlolwa kwezokwelapha.
A. Isikhwama sokudonsa umchamo namapayipi. Umchamo oluhlaza sasibhakabhaka oxubene noluhlaza satshani owabonwa ngemva kokufakwa kwepayipi lokukhipha umchamo esigulini esafika sinenkinga yokungakwazi ukukhipha umchamo.
B. Ukubukwa kwesitsha. Umchamo wesigameko esibikiwe esitsheni esingabulawanga amagciwane. Iphepha alibiki ukukhanya okuhlelwe ngezinga elifanayo, ukulinganiswa kombala omhlophe, noma ukuqoqa ngesikhathi esifanayo.
Izithombe: Imifanekiso 1 no-2 evela ku-Lionardi, Hengky, noHaruman, 2024, ephinde yashicilelwa ngaphansi kwe-CC BY 4.0; iguqulelwe ku-WebP ngaphandle kokushintsha imibala noma ukusikwa. Ababhali babika ukuthi isiguli savuma ukuba kushicilelwe. Kwasolwa i-methylene blue, kodwa ayiqinisekiswanga ngokuhlolwa kwamakhemikhali, ekuchayekeni emuthini wesintu. Lezi yizithombe zezokwelapha ezinemithombo eshiwo, hhayi indinganiso yombala elinganisiwe noma ubufakazi bokuthi into iyi-methylene blue. Isithombe sekhava singumfanekiso wokuchaza.
Yiziphi izinguquko ezidinga ukuhlolwa?

Isiqondiso se-NHS ngegazi emchamweni seluleka ukuthi kuhlolwe ngisho noma igazi lilincane noma kwenzeka kanye kuphela. Isiqondiso sayo nge-cyanosis sibheka ukushintsha ngokuzumayo kwezindebe, ulimi noma ubuso kube luhlaza sasibhakabhaka oxubene nompunga njengesimo esiphuthumayo. Ungalibazisi ukuthola usizo ngesikhathi uzama ukugeza umbala.
I-methylene blue iphinde ibe nengozi ye-hemolysis, okuwukubhujiswa kwamangqamuzana egazi abomvu, ikakhulukazi uma kukhona ukushoda kwe-G6PD. Ubuthakathaka obusha obukhulu noma ukuphuzi kwamehlo ngemva kokuchayeka kudinga ukuhlolwa ngokuphuthumayo, ngisho noma ukushintsha komchamo ekuqaleni bekubukeka njengodayi. Lokhu kuyahambisana nezimpawu ezibikiwe zokubhujiswa kwamangqamuzana egazi abomvu okuhlobene ne-G6PD. Isiqondiso esibanzi sokuphepha kwe-methylene blue sichaza izimo ezifanele lapho ingafanele ukusetshenziswa khona nokusebenzisana kwayo nezinye izinto.
Letha isitsha noma isithombe selebula yaso, inani nesikhathi sokuchayeka, kanye nohlu lwemithi yakho. Yazisa ilabhorethri nge-methylene blue: ingaphazamisa ukuhlolwa komchamo okuthembele esikhombisini esiluhlaza sasibhakabhaka. Lowo mlando uwusizo kakhulu kunokuzama ukulinganisa ukuthi isampula libukeka liluhlaza sasibhakabhaka kangakanani.
