Ntchito ndi kapangidwe ka dzino anthu

dzino ndi fupa mapangidwe, amene kusungidwa mu alveoli wa chapamwamba ndipo nsagwada m'munsi. Ntchito yaikulu ya pachibwano ndi akuigwiritsa chakudya, maphunziro coherent kulankhula ndi kugwira nawo ndondomeko ya kupuma.
Pali magulu angapo a mabungwe, omwe ali munthu dzino dongosolo. Mwachitsanzo, wodula 4 pabwino mu Pachithunzipa cha pachibwano, anafuna kuti chakudya particles mwachindunji nibbles. Pa mbali ya incisors ndi canines, amene allocated mtundu wapadera. Ntchito yawo yaikulu ndi kugumula chakudya mu tiziduswa tating'ono ting'ono. Yaikuluikulu molars zimakhudzidwa ndondomeko umapezeka ndi bwino umapezeka. Mano lakutali kuti awonekere kwa zaka 20, wotchedwa nzeru mano.
Total dzino dongosolo ndi kuti pali dentin ndi pakati. Phata la dzino wapangidwa ndi molekezera mitsempha ndi mitsempha, ndi dentin wa korona dzino TACHIMATA ndi enamel olimba. korona mano ali pamalo angapo, chifukwa pakati ali kumbali zonse zinayi. Obweretsa enamel ndicho chikhazikitso chovuta mu thupi lonse la munthu, chifukwa tichipeza calcium.
nsagwada dongosolo imakhala nambala mano (pa kukhwima ndi 32) anakonza chapamwamba ndipo m'munsi nsagwada fupa. Pakati pa mbali zonse ogwirizana nsagwada temporo-mandibular mafupa, chifukwa chimene angathe kutsegula ndi kutseka pakamwa. kudina zosavuta, kuti si kupatuka akuluakulu angathe anamva kayendedwe pamene mwadzidzidzi.
Kodi kuonetsetsa deciduous ndi mano okhazikika, chifukwa gulu lirilonse ndi ntchito yake. Mkaka mano kuonekera mu chaka choyamba cha moyo, kenako dana ndi m'malo mwa kukula mpaka kalekale. Kapangidwe ka mano chachikulu ndinazolowera kudya chakudya chotafuna limene mwana wayamba ntchito pang'onopang'ono. Komanso, mano mwana zofunika mapangidwe yachibadwa la nsagwada olowa ndi munthu wonse. Childs, zaka 1.5-2 mwana ayenera 20 mkaka mano. Makamaka zikamera wa mano woyamba ndi wotsatira sanali okhazikika ululu ndi kutupa m'kamwa ndi. Nthawi zambiri, mwanayo zambiri kukwiya ndi Moody, limatuluka kutentha thupi lake, ndi kutsekula m'mimba.
Kapangidwe Yosatha ya dzino aumbike mwa zaka 6-7. The ndondomeko ya mwamtheradi yemweyo monga kuphulika kwa mano chachikulu. kusintha komaliza limapezeka pafupifupi zaka 12-13, osati kuphatikizapo mano nzeru, zimene kukula patapita nthawi yaitali. Nthawi zambiri, nzeru dzino limakula momvetsa ndiponso pang'onopang'ono chimayamba kutha. Kupewa chiwonongeko gawo dzino dongosolo, izo tikulimbikitsidwa kuti kuwachotsa kwa dzino ndi kachilombo ndi sanaphwanye dongosolo pafupi.
Kumene, kapangidwe dzino ayenera kuchita zimenezi pa moyo. Insufficiently woyenera m'kamwa zaumoyo ndi kupanda zodzitetezera zingachititse kuti akuluakulu chiseyeye ndi mano. Tiyenera kukumbukira kuti ambiri mwa mankhwala kungasokoneze pa chikhalidwe ndi thanzi la mano anu, kotero iliyonse chakudya muyenera kuyeretsa pakamwa ku zotsalira chakudya. Njira yabwino ndi zonse kuyeretsa ndi burashi ndi phala, koma zimenezi si nthawi zonse zilipo mu mtsinje yamakono ya moyo. Pa nthawi, pali njira zambiri kusunga m'kamwa ukhondo tsiku lonse (kumatafuna chingamu, ulusi toothpicks, etc.).

Mano kuyeretsa ndondomeko ndi gawo osiyana mu mano kuyambira pali njira Mkhalidwe ndipo akulamulira dentifrice. Pamene monyanyira aliyense ndi zolakwika m'pofunika kuti kupempha thandizo kwa katswiri amene amasanthula ndi mankhwala chithandizo choyenera kapena kupewa matenda kugwira.
