Ngaba Amazinyo Aqwalaselwa Ngamathambo?
Umxholo
Amazinyo namathambo ajongeka ngokufanayo kwaye abelana ngezinto eziqhelekileyo, kubandakanya nokuba zezona zinto zinzima emzimbeni wakho. Kodwa amazinyo ayilolona thambo.
Le mbono iphosakeleyo inokuvela kwinto yokuba zombini ziqulathe ikhalsiyam. Ngaphezulu kweepesenti ezingama-99 zekhalsiyam yomzimba wakho enokufumaneka emathanjeni nasemazinyweni akho. Phantse iipesenti ezi-1 zifumaneka egazini lakho.
Ngaphandle koku, ukwenziwa kwamazinyo kunye namathambo kwahluke kakhulu. Umahluko wabo usazisa ukuba baphola njani kwaye kufuneka bakhathalelwe njani.
Enziwa ngantoni amathambo?
Amathambo ziithishu eziphilayo. Zenziwe ngeprotein collagen kunye ne-calcium phosphate. Oku kwenza ukuba amathambo omelele kodwa abe bhetyebhetye.
I-Collagen ifana ne-scaffolding ebonelela ngesakhelo sethambo. I-calcium igcwalisa okuseleyo. Ngaphakathi kwithambo linobusi obufana nobusi. Ibizwa ngokuba lithambo le-trabecular. Ithambo leTrabecular ligutyungelwe lithambo le-cortical.
Ngenxa yokuba amathambo ezihlunu eziphilayo, zihlala zilungiswa kwaye zihlaziywa ebomini bakho bonke. Izinto eziphathekayo azihlali zifana. Izicubu ezindala zonakele, kwaza kwenziwa nezicubu ezintsha. Xa amathambo eqhekeka, iiseli zethambo zikhawulezela kwindawo eyaphukileyo ukuqala ukuphinda kuhlaziye izicwili. Amathambo akwanomongo, ovelisa iiseli zegazi. Amazinyo awanomongo.
Zenziwe ngantoni amazinyo?
Amazinyo awanazo izicwili. Ziqulethwe ziindidi ezine ezahlukeneyo zethishu:
- dentin
- inkamela
- isamente
- umgubo
Intlama ingumbindi wezinyo. Inemithambo yegazi, imithambo-luvo kunye nezihlunu ezinxibelelanayo. I-pulp ijikelezwe yi-dentin, egutyungelwe yi-enamel.
I-enamel yeyona nto inzima emzimbeni. Ayinayo imithambo-luvo. Nangona ukuguqulwa kwakhona kwe-enamel kunokwenzeka, ayinakuzihlaziya okanye izilungise kwakhona ukuba kukho umonakalo omkhulu. Yiyo loo nto kubalulekile ukunyanga ukubola kwamazinyo kunye nemingxunya kungekudala.
Isamente igubungela ingcambu, phantsi komgca weentsini, kwaye inceda izinyo lihlale endaweni elungileyo. Amazinyo anezinye izimbiwa, kodwa awunayo i-collagen. Kuba amazinyo awaphili kwinyama, kubalulekile ukugcina ucoceko lomlomo oluhle, kuba ukonakala kwangoko kwamazinyo akunakulungiswa ngokwendalo.
Umgca wezantsi
Ngelixa amazinyo namathambo kusenokubonakala ngathi zizinto ezifanayo xa uqala nje, ngokwenene zahlukile. Amathambo anokuzilungisa kwaye aziphilise, ngelixa amazinyo engenako. Amazinyo abuthathaka ngakumbi kuloo nto, yiyo loo nto kubaluleke kakhulu ukuba usebenze ngococeko lwamazinyo kwaye ubone ugqirha wamazinyo rhoqo.
