Amakati nezinja zabangane abaningi azikhuliswa kusukela esemncane, ngakho-ke zifuna ngempela ukwazi ukuthi zineminyaka emingaki? Ingabe idla ukudla kwamakati nemidlwane? Noma udle ukudla kwenja nekati yabantu abadala? Ngisho noma uthenga isilwane kusukela esemncane, usazibuza ukuthi isilwane sineminyaka emingaki, ingabe sinezinyanga ezi-2 noma izinyanga ezi-3 ubudala? Ezibhedlela, ngokuvamile sisebenzisa amazinyo ukuze sinqume ubudala bezilwane ezifuywayo.

Amazinyo anomehluko omkhulu kuye ngokudla akudlayo kanye nemikhuba yawo yokudla, kanye nenani lamazinyo agaya amathoyizi nokudla okulula okusetshenzisiwe. Ngakho-ke, ngokujwayelekile, anembe ngokuqhathaniswa emidlwaneni namakati, kanti ezinjeni ezindala, ukuphambuka kungase kube okuphawulekayo. Yebo, lokho okubizwa ngokuthi ukuchezuka nakho kulinganiselwe. Kujwayelekile ukuthi inja eneminyaka emihlanu idle amathambo inamazinyo agugekayo aklebhule njengawenja eneminyaka engu-10 kodwa awukwazi ukuhlangana nenja eneminyaka engu-10 inamazinyo afana ne inja eneminyaka emi-5. Ngake ngahlangana nomnikazi wesilwane esifuywayo owaletha isilwane esifuywayo esinezinwele ezisagolide esasithi sineminyaka engu-17 ubudala. Kwakuyinto enkulu leyo, futhi kwakudingekile ukuba kunqunywe iminyaka yayo nesimo somzimba sokwelashwa. Ivula umlomo wayo ukuze ibone amazinyo ayo, kwakulinganiselwa ukuthi yayineminyaka engu-7 kuphela ubudala. Ngabe ngikhumbula iminyaka yogogo nomkhulu ngokungalungile?

Yiqiniso, ukubheka amazinyo ebuntwaneni kungase futhi kwembule izifo eziningi zezilwane ezifuywayo, njengokuntuleka kwe-calcium namazinyo asemigqeni emibili. Ngakho-ke kubalulekile ukufunda ukuthi ungabheka kanjani ukuthuthukiswa kwamazinyo, ukunquma iminyaka nempilo yabo.

Izinja ziqala ukwakha amazinyo aphumayo kusukela ezinsukwini ezingu-19 kuya kwezingu-20 ngemva kokuzalwa; Emavikini angu-4-5 ubudala, ama-incisors esifuba sokuqala nesesibili anobude obulinganayo (ama-incisors); Emavikini angu-5-6 ubudala, izinyo lesithathu lokusika linobude obulinganayo; Emidlwaneni enamasonto angu-8, wonke ama-incisors amabele akhule ngokugcwele, futhi amazinyo esifuba amhlophe futhi amancane futhi abukhali;

Phakathi nezinyanga ezingu-2-4 ngemva kokuzalwa, izinja kancane kancane zishintsha amazinyo azo, zichithe futhi zikhule ama-incisors amasha kusukela ku-incisor yokuqala; Kusukela eminyakeni engu-5-6 izinyanga, buyisela incisors yesibili neyesithathu kanye canines; Eminyakeni engu-8-12, wonke ama-molars ashintshwa ngamazinyo angapheli (amazinyo ahlala njalo). Amazinyo ahlala njalo amhlophe futhi ayacwebezela, kanti ama-incisors anezici ezicijile. Uma kuvela okuphuzi, kubonisa i-tartar;

Uma inja ineminyaka engu-1.5 kuya kwemi-2 ubudala, isiqongo esikhulu se-mandibular incisor yokuqala (izinyo langaphambili) siyaguga futhi siguge ngesiqongo esincane, esibizwa ngokuthi i-peak wear out; Eminyakeni engu-2.5, ukuphakama kwe-mandibular incisor yesibili (izinyo eliphakathi) kugugile; Eminyakeni engu-3.5, ukuphakama kwe-incisors ye-maxillary kugugile; Eminyakeni engu-4.5, ukuphakama kwezinyo le-maxillary eliphakathi ligugile; Iminyaka yokweva eshumini nambili yezinja iyaphela, futhi izinguquko emazinyweni phakathi nalesi sikhathi azithintwa izici zobudala njengokudla ezikudlayo, ngakho kancane kancane ziya zingalungile.

Kusukela eminyakeni engu-5, i-incisor yesithathu kanye ne-canine ithiphu ebunzini eliphansi igqoke kancane (hhayi isicaba), kanti i-incisors yokuqala neyesibili inesimo esingunxande; Lapho eneminyaka engu-6 ubudala, ukuphakama kwe-incisor yesithathu ye-maxillary kancane kugugile, futhi amazinyo e-canine abuthuntu futhi ayindilinga; Lapho eneminyaka engu-7 ubudala, i-mandibular incisors yezinja ezinkulu igqoke impande, ene-longitudinal elliptical surface; Lapho eneminyaka engu-8, ama-incisors enja enkulu ayagqokwa futhi atshekele phambili; Lapho eneminyaka engu-10 ubudala, indawo egqokekayo ye-mandibular yesibili incisor kanye ne-maxillary incisor i-elliptical longitudinally; Izinja ezinkulu ngokuvamile ziphila iminyaka eyi-10-12 futhi azivamile ukuzwa ukulahlekelwa amazinyo, ngokuvamile ngenxa yokuguga okukhulu;

Lapho eneminyaka engu-16 ubudala, inja encane inesikhathi eside sokuphila, noma kunalokho inja evamile esekhulile ene-incisors engekho, amazinyo e-canine angaphelele, namazinyo aphuzi angalingani; Lapho eneminyaka engu-20, amazinyo e-canine awela futhi cishe kwakungekho amazinyo emgodini womlomo. Ukudla ngokuyinhloko kwakuwukudla okuwuketshezi.

Uma kuqhathaniswa nezinja ezivame ukugaya amazinyo ezintweni eziqinile, okwenza kube nzima ukunquma iminyaka ngenxa yokuguga kwamazinyo, amazinyo amakati akhula njalo futhi angasetshenziswa njengendlela engcono kakhulu yokwahlulela ubudala.

Amazinyo e-canine amakati made, aqinile futhi abukhali, anempande kanye nethiphu. Lapho umgodi womlomo uvaliwe, amazinyo e-canine aphezulu atholakala ohlangothini lwangaphandle lwangaphandle lwamazinyo aphansi e-canine. Kukhona igebe ngemuva kwamazinyo e-canine, okuyi-molar yangaphambili. I-premolar yokuqala incane kakhulu, eyesibili i-premolar inkulu, kanti eyesithathu i-premolar inkulu kakhulu. Womabili ama-premolars angaphezulu naphansi anamathiphu amane amazinyo, kanti ichopho lezinyo eliphakathi lilikhulu futhi libukhali, elingadabula inyama. Ngakho-ke, libizwa nangokuthi izinyo eliqhekekile.
