Kungakhiwa yini izithelo zomvini uyoba isikhali entsha ekulweni nokubola kwamazinyo?

Izinga eliphakeme kunawo kwamagilebhisi iqukethe kwakwakhe yemvelo oluqinisa amazinyo futhi kuvimbele caries. Lokhu yaziwa izisebenzi ekolishi wodokotela bamazinyo kusukela University of Illinois e-Chicago. Ososayensi bathi ukutholakala zabo ezintsha kungavimbela kwamazinyo kubantu abaningi. Njengoba imbewu yamagilebhisi akhiphe uyakwazi ukwandisa amandla kophawu, ukuvumela kwakhe ukukhonza isikhathi eside.

Kuyini ephawulekayo leyavela embonini iwayini?

Ngokuvamile, niphonsa imbewu yamagilebhisi emva kokudla amajikijolo namanzi. Kodwa umkhakha iwayini ukukhiqizwa udoti-DRM. Extract imbewu yamagilebhisi, leyavela zokukhiqiza iwayini sekuyisikhathi eside, edayiswa ezitolo ukudla impilo. It is wafakazela ukuthi kuyazuzisa yokuthuthukisa imisebenzi inhliziyo kwegazi. Futhi manje, abacwaningi Chicago ukwazile ukwambula omunye umsebenzi ewusizo komkhiqizo. compounds zemvelo ezitholakala imbewu yamagilebhisi akhiphe olungavimba ukuphuma amazinyo, okwandisa ubude bokuphila ofakwe esiyinhlanganisela e iziguli nemitholampilo kwamazinyo. Izinga inkonzo nokuphila lwezimpawu ngemva sokubuyiselwa amazinyo nge izinto esiyinhlanganisela ngokuvamile ingeqi iminyaka 5-7.

Ingqikithi yalo ukutholakala

Ososayensi bathole ukuthi akhiphe imbewu yamagilebhisi kuqinisa dentin - amathambo izinyo izidakamizwa okuwugcwalisile ngalo ingaphakathi ngaphansi olukhuni yangaphandle koqweqwe lwawo ungqimba. Lapho amazinyo zilimele, izinto uphawu ayikwazi ukunikeza adhesion eliqinile le ukuze izicubu namathambo. Kodwa manje, ngoba zonke ziguli ezikhetha zezinhlanganisela sokubuyiselwa yamazinyo, kukhona izindaba ezinhle. Ngakolunye uhlangothi, la ofakwe kukhona ukubukeka yobuhle ngaphezulu, kodwa ngakolunye uhlangothi, abakwazi ukuncintisana ngokuya ukusebenza ofakwe ziyinhlanganisela, okuyizindawo inkosi 10 kuya ku-15 iminyaka (noma ngaphezulu). Lapho impahla itholakala alengayo phezu kwendawo ezilimele emhlabeni Yaqala iba yingxenye yomhlabathi izicubu. Ngaphambi Chicago bamazinyo umsebenzi kwaba ukuthola ikhemikhali enobuthi ngcono adhesion phakathi ofakwe esiyinhlanganisela bone izidakamizwa.

Abantu abaningi bavezwa kwamazinyo

Ngakho, lapho egcwalisa amazinyo bamba ingashintshwa ngokusebenzisa izinto ezintsha zemvelo. Ngokwe-Oral Health Foundation, ingxenye yesithathu yomphakathi wabantu omdala ababhekene nazo emazweni asethuthukile has caries. Angaba yizingxenye ezine Angaphezu kuka sabantu UK has uphawu okungenani oyedwa. Futhi njengoba caries iqhubeka, Inani eliyisilinganiso ofakwe izakhamizi Albion kuziwa eziyisikhombisa.

Njengoba caries ebhubhisa amazinyo?

Caries kwenzeka uma emlonyeni (ikakhulukazi emhlabeni amazinyo) zanqwabelana qwembe acid esesikhundleni nethonya elilimaza. Uma ukudla futhi wenze iziphuzo okusezingeni eliphezulu carbohydrate, ama-bacterium abahlala qwembe ukuguqula ushukela ube namandla. Lokhu kunomthelela ukwanda kwabo okusheshayo. Uma isikhathi akusho banakekele ngomlomo ingaphakathi kwenhlanzeko entrained amnandi ukudla acid ebhubhisa izinyo koqweqwe lwawo, okuholela kwamazinyo, futhi kukhona (izimbobo ezincane). Kuleso simo, uma ungathandi wamazinyo njalo, i-asidi iqala ukubhubhisa ungqimba olandelayo izinyo, le dentin. Ngenxa yalokho, emazinyweni avele izimbotshana abakhulu, futhi uma ungenalo ukubeka uphawu ngesikhathi, ungalahlekelwa esiningi izinyo.

Indlela yokuvimbela ukubhujiswa dentin?

Uma caries akuyona sezibhekwa njengosongo olukhulu kuwe, khona-ke imbubhiso ithambo lwalezozinto izinyo kuyinkinga enkulu ngaphezulu. Dentine siqukethe i-collagen, amaprotheni kwesakhiwo kwezicubu zezinzwa. Abacwaningi bathola ukuthi i-collagen ungakhiqiza kabusha kabana iqembu flavonoid oligomeric proanthocyanidins. Lezi zinto zehlela isitshalo ingatholakala imifino eziningi, kodwa amaqhawe okuqukethwe kwabo kubhekwe njengento imbewu yamagilebhisi akhiphe. Lapho odokotela bamazinyo ukunikeza unamathelise izinyo ezilimele, indaba esiyinhlanganisela kufanele abe adhesion ezinhle dentin. Ezinye izindawo kunzima okubuyisela, okuyinto kunciphisa ukuphila service. Uma dentin namanje ocebile collagen, inikeza adhesion kangcono futhi kuvimbela Ukungena umswakama. Kodwa manje ososayensi bathole indlela ukunciphisa ukuphuma amazinyo.
