Umsebenzi nokuba isigqeba yezinyo kwabantu

A izinyo i ukuyilwa ithambo, apho igcinwa kwi alveoli eliphezulu kunye nemihlathi asezantsi. Umsebenzi ophambili kwemihlathi sele gawula ukutya, imfundo intetho enentsingiselo nokuthatha inxaxheba kwinkqubo nokuphefumla.
Kukho amaqela eziliqela ezikhoyo, nganye eneyazo isakhiwo izinyo ngamanye. Umzekelo, lo mgawuli 4 ezibekwe ongaphambili kwemihlathi, ilungiselelwe amasuntswana ukutya ngqo nibbles. Ngapha nangapha siphume ke canines, ezo zabelwe ifomu eyahlukileyo. Owona msebenzi lwabo eziqwenga ukutya zibe ngamaqhekeza amancinci. Ezinkulu nezincinci imihlathi inxaxheba kwinkqubo sokusila nokutshixiza ngokucokisekileyo ngakumbi. Amazinyo liqhele ezibonakala engama-20, ekuthiwa amazinyo ubulumko.
Iyonke isakhiwo izinyo kukuba kukho dentin kunye engundoqo. Undoqo izinyo ubunjwe kwalapho kunye imithambo yegazi, kwaye dentin isithsaba izinyo isale a wayesebenzisa okuqinileyo. isithsaba amazinyo iye iindawo eziliqela, ekubeni core singqongwe kuzo zonke macala omane. wayesebenzisa kukodwa ke into inzima kakhulu yonke umzimba womntu, ekubeni lenziwa calcium.
Isakhiwo umhlathi siqulathe inani amazinyo (at ekuvuthweni 32) ezisisigxina ephezulu nesezantsi ithambo umhlathi. Phakathi zombini iindawo oxhulumene emhlathini temporo-mandibular amalunga, ngenxa osenokuba nokuvula nokuvala emlonyeni. unqakrazo lula, ukuba akukho unxaxho enzulu weva iintshukumo xa ngequbuliso.
Ukuba ama ezinamagqabi avuthulukayo kwamazinyo, kuba iqela ngalinye umsebenzi walo. amazinyo Ubisi kuvela kunyaka wokuqala wobomi, baza ngokuthe ngcembe ewa kwaye endaweni ukhulisayo ngokusisigxina. Ubume kwamazinyo zaseprayimari aguqulelwe ukutya ukutya okuqinileyo apho umntwana esoloko isetyenziswa ngokuthe ngcembe. Kwakhona, amazinyo baby zibalulekile kumiswa eqhelekileyo welungu imihlathi umntu xa iyonke. Ngokuqhelekileyo, iminyaka 1.5-2 umntwana kufuneka libe 20 amazinyo ubisi. Ingakumbi ukuvela kwamazinyo lokuqala elandela non-esisigxina buhlungu, kunye ukudumba iintsini. Amaxesha amaninzi, umntwana uba nochuku yaye eguquguqukayo, ubushushu bomzimba wakhe liphuma, kukho norhudo.
esakhiwe izinyo senziwa kwiminyaka 6-7. Ngokulandelelana ngokupheleleyo ziyafana kuqhambuko amazinyo zaseprayimari. utshintsho lokugqibela kwenzeka malunga iminyaka 12-13, hayi kuquka amazinyo ubulumko, leyo ikhule kakhulu kamva. Amaxesha amaninzi, izinyo ubulumko sikhula kabuhlungu kwaye kancinane uyaqala ukuba ndiludilize. Ukunqanda ukutshatyalaliswa isakhiwo kwisigaba izinyo, kucetyiswa ukuba awasuse i izinyo owosulelekileyo akukho badlwengulwe isakhiwo ezikufutshane.
Kakade ke, ubume izinyo kufuneka kugcinwe ubomi. Ngokwaneleyo ukunakekela enobuchule impilo yomlomo kunye nokungabikho amanyathelo othintelo kunokukhokelela enkulu isifo seentsini kunye ukubola kwamazinyo. Kufuneka kukhunjulwe ukuba uninzi lweemveliso kuba nefuthe elibi kwi imeko kunye nempilo amazinyo akho, ukuze emva kokudla kufuneka ukucoca umlomo evela kwintsalela ukutya. Le ndlela ifanelekileyo kukuba ukucoca rhoqo ibhrashi kunye paste, kodwa oku akusoloko ayifumaneki kumsinga mihla ubomi. Okwangoku, zininzi iindlela ukugcina ucoceko yomlomo imini yonke (ukuhlafuna itshungama, umsonto, imicinga yokuvungula, njalo njalo).

inkqubo wokucoca kwamazinyo icandelo elahlukileyo kwi woogqirha bamazinyo ekubeni kukho indlela qualitative nemigaqo dentifrice. Xa naziphi na izitenxo nokuphambuka kuyacetyiswa ukuba bafune uncedo zabucala ezithe ayihlolayo ukumisela unyango olufanelekileyo okanye nokukhuselwa kwezifo ubambe.
