Umsebenzi kanye nesakhiwo izinyo womuntu

A izinyo kuyinto ukwakheka ithambo, okuyinto lilondolozwe alveoli elingenhla kanye nemihlathi aphansi. Umsebenzi oyinhloko umhlathi ocanda ukudla, imfundo inkulumo ecacile iqhaza inqubo emishinini yokuphefumula.
Kunamaqembu eziningana izinhlangano, ngamunye ephethe isakhiwo izinyo ngabanye. Ngokwesibonelo, wokusika 4 isebangeni ongaphambili emhlathini, senzelwe izinhlayiyana zokudla oqondile nibbles. On zombili amazinyo kukhona canines, okuyinto abelwe ifomu eyingqayizivele. Umsebenzi wawo oyinhloko kokubahlubula ukudla ku izingcezu ezincane. Ezinkulu nezincane molars zinengxenye inqubo ukugaya ukugaya ngokuphelele. Amazinyo ezikude evelayo iminyaka engu-20, okuthiwa ukuhlakanipha amazinyo.
Ubude izinyo isakhiwo wukuthi kukhona dentin futhi ekujuleni kwenhliziyo. Umnyombo izinyo yakhiwa kwalapho kuhlangana khona imizwa nemithambo yegazi, futhi dentin umqhele izinyo is camera nge koqweqwe lwawo okuqinile. umqhele zamazinyo has evele eziningana, kusukela core uzungezwe nxazonke ezine. koqweqwe lwawo Sheer kungukuqiniseka sekukaningi kuyo yonke indikimba womuntu, ngoba liqukethe i-calcium.
emhlathini isakhiwo siqukethe sesibalo samazinyo (ekuvuthweni kuyinto 32) fixed yasenhla nemithombo yasenzansi emhlathini ithambo. Phakathi kwakho kokubili izingxenye axhunyiwe emhlathini temporo-mandibular amalunga omzimba, ngenxa okuyinto kungenzeka ibe ivula ivala umlomo. ukuchofoza lula, ukuthi akuyona ukuphambuka sina ungezwakala ukunyakaza lapho okungazelelwe.
Kufanele ukwaba lezihlahla namazinyo unomphela, ngoba iqembu ngalinye likwazi lwenza umsebenzi walo ohlukile. Ubisi namazinyo avele onyakeni wokuqala wokuphila, kancane kancane fall out futhi esikhundleni akhulise unomphela. Isakhiwo namazinyo eyinhloko aguqulelwe ukudla ukudla okuqinile lapho ingane Ufika esetshenziswa kancane kancane. Futhi, amazinyo ezinsana kubalulekile ukuze kumiswa ejwayelekile joint emhlathini nomuntu iyonke. Ngokuvamile, iminyaka 1.5-2 umntwana kufanele kube 20 ubisi amazinyo. Ikakhulukazi ukuvela amazinyo kuqala futhi okwalandela angesiwo agcwele kuyinto ubuhlungu, futhi ukuvuvukala izinsini. Isikhathi esining impela, ingane iba ekuhluthukeni futhi eguquguqukayo, izinga eliphansi lokushisa komzimba wakhe liphume, kukhona isifo sohudo.
kwakhiwa isakhiwo unomphela izinyo is eminyakeni 6-7. Kulandzelana kwalokucuketfwe lokuhleliwe ngokuphelele kuyafana ukuqhuma namazinyo eyinhloko. ushintsho Final kwenzeka cishe iminyaka 12-13, hhayi kuhlanganise nokuhlakanipha amazinyo, ezimila kamuva kakhulu. Isikhathi esining impela, izinyo ngokuhlakanipha ikhula kabuhlungu futhi kancane uqala ziwohloke. Ukuze ugweme ekubhujisweni isigaba izinyo isakhiwo, kutuswa ukuba bawasuse i izinyo onegciwane is umthetho isakhiwo eduze.
Yiqiniso, kufanele isakhiwo izinyo zigcinwe kukho konke ukuphila. Insufficiently abanekhono ukunakekelwa kwezempilo ngomlomo kanye nokuntuleka izinyathelo zokuvimbela kungaholela sina nesifo sezinsini futhi ukubola kwamazinyo. Kufanele kukhunjulwe ukuthi iningi imikhiqizo abe nomthelela omubi isimo nempilo amazinyo akho, ngakho njalo ngemva kokudla kumelwe bahlanze umlomo kusuka ukudla ezisalayo. Inketho okahle yokuhlanza njalo nge ibhulashi nokunamathisela, kodwa akunjalo ngaso sonke isikhathi etholakala ukusakaza yesimanje yokuphila. Okwamanje, kunezindlela eziningi ukulondoloza ukuhlanzeka temlomo usuku lonke (ushingamu, intambo, asikiweko, njll).

Amazinyo yokuhlanza nqubo ingxenye ehlukile amazinyo ngoba kukhona inqubo qualitative obusa dentifrice. Lapho yimuphi mfihlo ngeziphambeko uyelulekwa ukufuna usizo onguchwepheshe ohlola futhi zibeka ukwelashwa okufanele noma nokuvinjelwa kwezifo ubamba.
