Katsi nembwa dzeshamwari dzakawanda hadzisimudzwe kubva paudiki, saka ndoda kuziva kuti vane makore mangani? Kudyira katsi nembwanana here? Kana kudya chikafu chembwa nekatsi yevakuru? Kunyangwe iwe ukatenga chipfuwo kubva paudiki, iwe unozoda kuziva kuti inguva yakadii mhuka inovaraidza. Imwedzi miviri here kana mwedzi mitatu? Muzvipatara, tinowanzoona zera remhuka dzinovaraidza kuburikidza nemeno.

Pane musiyano wakakosha pakati pemazino nekuda kwekudya kwakasiyana uye tsika dzekudyisa, kushandiswa kwakasiyana kwemazino ekugeda matoyi uye svutugadzike, saka kazhinji kutaura, mazino anozove akanyatso kurongeka kune puppies uye kittens, nepo kutsauka kungave kwakakura kune vakuru. imbwa. Zvechokwadi, kunonzi kutsauka kunewo pakati. Imbwa ine makore mashanu inogara ichidya mapfupa, uye zino rinopera rakafanana nerembwa ine makore gumi. Asi haugone kusangana nembwa ine makore gumi ine mazino akafanana neembwa ine makore mashanu. Kare, ndakasangana nemuridzi wemhuka akauya nebvudzi regoridhe rainzi 17 years old. Chinhu chikuru. Inoda kuziva zera uye mamiriro emuviri isati yarapwa. Inofungidzirwa kuva nemakore manomwe paunoshama muromo kuti uone mazino. Kwakaipa here kurangarira zera rasekuru nasekuru vake?

Ehe, kana uchiri mudiki, iwe unogona zvakare kuziva hosha dzakawanda dzemhuka dzinovaraidza nekucherechedza mazino avo, sekunge ivo vasina calcium uye vane mitsara miviri yemeno. Saka zvakakosha kudzidza kuti ungatarisa sei kukura kwemeno uye kutonga makore avo uye hutano.

Imbwa inotanga kukura mazino anocheka mazuva 19-20 mushure mekuberekwa; Pamasvondo mana-5, yekutanga uye yechipiri mazamu incisors akaenzana kureba (incisors); Kana 5-6 mavhiki ezera, yechitatu incisor yakaenzana; Kune vana vemavhiki masere, ma-incisors akakura zvakakwana, uye mazino anocheka akachena uye akaonda uye akapinza;

Mukati memwedzi 2-4 yekuberekwa, vana vaduku vakatanga kuchinja zvishoma nezvishoma mazino anocheka, uye yekutanga incisor yakatanga kudonha uye kukura matsva incisors; Yechipiri uye yechitatu incisors uye canines inotsiviwa pazera remwedzi 5-6; Pazera remwedzi misere kusvika kumwedzi gumi nemiviri, ose molars anotsiviwa nemazino echigarire (mazino asingaperi). Mazino echigarire akachena uye akajeka, uye incisors ane protrusions dzakapinza. Kana pane yero, zvinoreva kuti pane tartar;

Kana imbwa iine makore 1.5-2, iyo huru yepamusoro yekutanga mandibular incisor (incisor) yakasakara, uye inoputika nepamusoro pepamusoro, iyo inonzi peak kupera; Pazera re2.5, cusp yechipiri mandibular incisor (zino repakati) yakanga yasakara; Pazera re 3.5, iyo yepamusoro ye maxillary incisor yakasakara; Pazera re4.5, cusp yepakati maxillary zino yakanga yasakara; Uku ndiko kuguma kwehujaya hwembwa. Zino rinoshanduka panguva iyi harina kukanganiswa nezera rezera pane chikafu chekudya, saka zvishoma nezvishoma vanova vasina kururama.

Sezvo imbwa yaiva nemakore mashanu, yechitatu incisor yehuma yakadzika uye canine cusp yakanga yakapfekwa zvishoma (isina kuputika), uye yekutanga uye yechipiri incisors yaiva rectangular; Pazera remakore matanhatu, cusp yechitatu maxillary incisor yakanga yakapfekwa zvishoma, uye mazino e canine akanga asina kujeka uye akapoteredza; Pazera remakore 7, mandibular incisors yembwa huru dzaive dzakapfekwa kumudzi, uye nzvimbo yekukuya yaiva vertical oval; Pazera re8, mandibular incisors yembwa huru dzakasakara uye dzakarerekera mberi; Pazera re10, kupfeka pamusoro pemandibular yechipiri incisor uye maxillary incisor yaiva longitudinal ellipse; Imbwa huru dzinowanzogara kwemakore gumi-12, uye kashoma kuva nemazino anodonha, izvo zvinowanzopfeka zvakakomba;

Kana imbwa duku ine makore 16 okukura, ine nduramo refu, kana kuti imbwa yakajairika. Iyo incisors inowira pasi, mazino e canine haana kukwana, uye iyo inonyanya kuzivikanwa mazino eyero asina kuenzana; Pazera remakore makumi maviri, mazino embwa akadonha, uye pakanga pasina mazino mumuromo.

Zvichienzaniswa nembwa dzinowanzogeda-geda zvinhu zvakaoma kugeda mazino, izvo zvinoita kuti zviome kutonga zera nekuda kwekupfeka mazino. Mazino ekitsi anokura nguva dzose uye anogona kunge akashandiswa seyakanakisa mwero wekutonga zera.

Mazino e canine ekitsi akareba, akasimba uye akapinza. Mazino embwa ane mudzi wezino uye muromo wezino. Kana muromo wemuromo wakavharwa, mazino epamusoro e canine anowanikwa kune posterolateral side yemazino ezasi e canine. Pane mukaha kuseri kwe canine zino. Yekutanga premolar idiki, yechipiri premolar yakakura, uye yechitatu premolar ndiyo yakakura. Iwo epamusoro uye epasi premolars ese anoumbwa nemazano mana emazino. Zino repakati zino rakakura, rakapinza, uye rine mhedzisiro yekutsemura nyama, saka inonziwo zino rakatsemuka.

Katsi inokura mazamu ayo ekutanga incisor mavhiki 2-3 mushure mekuberekwa; Yechipiri uye yechitatu incisors uye canines inoumbwa kumativi 3-4;

Katsi dzinokura yekutanga uye yechipiri incisors kutsiva mazamu incisors paanenge 3.5-4 mwedzi; Pazera remwedzi 4-4.5, yechitatu incisor inokura kuti itsive incisor yezamu; Mazino eCanine anokura mukati memwedzi mishanu kutsiva mazino embwa dzemwana;

Katsi inokura premolar mazino anenge 2 mwedzi; Yechipiri neyechitatu deciduous premolars inokura pamwedzi 4-6, uye zvishoma nezvishoma inotsiviwa nekusingaperi premolars; Yekutanga posterior molar inokura pamwedzi 4-5. Iyo huru zino kutsiva zera rekati rinenge 4-6 mwedzi. Munguva iyi, vanogona kurasikirwa nechido nekuda kwemazino.

Mushure mokunge kati iine 1 gore, incisors yayo yakaderera inotanga kupfeka; Mushure memakore manomwe, mazino ekati ekati akatanga kukwegura zvishoma nezvishoma, uye mandibular incisors yakave yakakomberedzwa; Mushure memakore gumi, mazino epamberi eshaya yepamusoro yekatsi anogona kudonha, saka unogona kugadzirisa kudya kwako maererano nekuchinja kwe te.
