Amakati nezinja zabangane abaningi azikhuliswanga kusukela ebuntwaneni, ngakho-ke ngingathanda ukwazi ukuthi zineminyaka emingaki?Ingabe idla ukudla kwamakati nemidlwane?Noma udle ukudla kwenja nekati yabantu abadala?Ngisho noma uthenga isilwane kusukela ebuntwaneni, uzofuna ukwazi ukuthi isilwane sineminyaka emingaki.Ngabe yizinyanga ezi-2 noma izinyanga ezi-3?Ezibhedlela, ngokuvamile sinquma ubudala bezilwane ezifuywayo ngamazinyo.

Kunomehluko omkhulu phakathi kwamazinyo ngenxa yemikhuba ehlukene yokudla nokudla, ukusetshenziswa okuhlukene kwamathoyizi okugaya izinyo nokudla okulula, ngakho-ke, uma sikhuluma nje, amazinyo ayoba anembe kakhulu emidlwaneni nasemazinyaneni, kuyilapho ukuphambuka kungase kube kukhulu kubantu abadala. izinja.Yebo, lokho okubizwa ngokuthi ukuchezuka nakho kulinganiselwe.Inja eneminyaka engu-5 ubudala idla amathambo njalo, kanti ukuguga kwamazinyo kuyefana nelenja eneminyaka engu-10 ubudala.Kodwa awukwazi ukuhlangana nenja eneminyaka engu-10 ubudala enamazinyo afana nenja eneminyaka emihlanu ubudala.Ngaphambili, ngahlangana nomnikazi wezilwane ezifuywayo owaletha izinwele zegolide ezibizwa ngokuthi iminyaka engu-17 ubudala.Yinto enkulu leyo.Idinga ukunquma ubudala nesimo somzimba ngaphambi kokuba zelashwe.Ilinganiselwa eminyakeni engu-7 ubudala lapho uvula umlomo wakho ukuze ubone amazinyo.Ingabe akulungile ukukhumbula iminyaka yogogo nomkhulu wakhe?

Yiqiniso, lapho usemncane, ungakwazi futhi ukwazi izifo eziningi zezilwane ezifuywayo ngokubheka amazinyo azo, njengokuthi ayinayo i-calcium futhi inemigqa emibili yamazinyo.Ngakho-ke kubalulekile ukufunda ukuthi ungabheka kanjani ukuthuthukiswa kwamazinyo futhi wahlulele iminyaka nempilo yabo.

Inja iqala ukukhula amazinyo avuzayo ezinsukwini ezingu-19-20 ngemva kokuzalwa;Emavikini angu-4-5 ubudala, ama-incisors esifuba sokuqala nesesibili anobude obufanayo (ama-incisors);Lapho amaviki angu-5-6 ubudala, i-incisor yesithathu ilinganayo;Emidlwaneni enamaviki angu-8 ubudala, ama-incisors ama-deciduous akhule ngokugcwele, futhi amazinyo aphuzi amhlophe futhi amancane futhi abukhali;

Phakathi nezinyanga ezingu-2-4 zokuzalwa, imidlwane yaqala ukushintsha kancane kancane amazinyo aphelile, futhi i-incisor yokuqala yaqala ukuwa futhi ikhule ama-incisors amasha;I-incisors yesibili neyesithathu kanye nama-canines ashintshwa eneminyaka engu-5-6;Eminyakeni eyizinyanga eziyi-8 kuya kweziyi-12, wonke ama-molars ashintshwa ngamazinyo angapheli (amazinyo ahlala njalo).Amazinyo ahlala njalo amhlophe futhi agqamile, kanti ama-incisors ane-protrusions ebukhali.Uma kukhona ophuzi, kusho ukuthi kune-tartar;

Lapho inja ineminyaka engu-1.5-2 ubudala, isiqongo esikhulu se-mandibular incisor yokuqala (i-incisor) sigugile, futhi sigubha nge-peak encane, ebizwa ngokuthi i-peak wear out;Lapho eneminyaka engu-2.5, i-cusp ye-mandibular incisor yesibili (izinyo eliphakathi) yayigugile;Lapho eneminyaka engu-3.5, ukuphakama kwe-incisor maxillary kwase kugugile;Lapho eneminyaka engu-4.5, i-cusp yezinyo le-maxillary eliphakathi lase ligugile;Isiphetho sobusha benja.Izinyo ezishintshayo phakathi nalesi sikhathi azithintwa kancane yisici sobudala kunesici sokudla, ngakho kancane kancane ziba nokungalungile.

Njengoba inja yayineminyaka engu-5 ubudala, i-incisor yesithathu yebunzi eliphansi kanye ne-canine cusp yayigqoke kancane (hhayi isicaba), kanti i-incisors yokuqala neyesibili yayiyi-rectangular;Lapho eneminyaka engu-6 ubudala, i-cusp ye-maxillary incisor yesithathu yayigugile kancane, futhi amazinyo e-canine ayengacacile futhi ayindilinga;Lapho eneminyaka engu-7 ubudala, ama-mandibular incisors ezinja ezinkulu ayegqokwe empandeni, futhi indawo yokugaya yayiyi-oval eqondile;Eminyakeni engu-8, ama-mandibular incisors ezinja ezinkulu agqoke futhi athambekele phambili;Lapho eneminyaka engu-10 ubudala, ukugqoka okuphezulu kwe-mandibular yesibili incisor kanye ne-maxillary incisor kwakuyi-ellipse longitudinal;Izinja ezinkulu ngokuvamile zihlala iminyaka eyi-10-12, futhi kuyaqabukela zibe namazinyo aqatha, okuvame ukuguga kakhulu;

Lapho inja encane ineminyaka engu-16 ubudala, iphila isikhathi eside, noma inja endala evamile.Ama-incisors awela, amazinyo e-canine awaphelele, futhi okuvame kakhulu amazinyo aphuzi angalingani;Lapho eneminyaka engu-20 ubudala, amazinyo e-canine awela phansi, futhi cishe kwakungekho namazinyo emlonyeni.

Uma kuqhathaniswa nezinja ezivame ukuququda izinto ezinzima ukuze zigaye amazinyo, okwenza kube nzima ukwahlulela iminyaka ngenxa yokuguga kwamazinyo.Amazinyo amakati akhula njalo futhi acishe asetshenziswe njengezinga elingcono kakhulu lokwahlulela iminyaka.

Amazinyo e-canine amakati made, aqinile futhi abukhali.Amazinyo e-canine anempande yezinyo kanye nechopho lezinyo.Lapho umgodi womlomo uvaliwe, amazinyo e-canine aphezulu atholakala ohlangothini lwe-posterolateral lwamazinyo aphansi e-canine.Kukhona igebe ngemuva kwezinyo le-canine.I-premolar yokuqala incane kakhulu, eyesibili i-premolar inkulu kakhulu, kanti eyesithathu i-premolar inkulu kakhulu.Ama-premolars aphezulu naphansi wonke akhiwe ngamathiphu amane wamazinyo.Ithiphu lezinyo eliphakathi likhulu, libukhali, futhi linomphumela wokudabula inyama, ngakho libizwa nangokuthi izinyo elihlukanisiwe.

Ikati likhulisa isifuba salo sokuqala emasontweni angu-2-3 ngemva kokuzalwa;I-incisors yesibili neyesithathu kanye nama-canines akhiwa cishe ngo-3-4;

Amakati akhula ama-incisors okuqala kanye nesesibili ukuze athathe indawo ye-incisors yebele cishe ezinyangeni ezi-3.5-4 ubudala;Lapho eneminyaka engu-4-4.5 izinyanga, i-incisor yesithathu ikhula esikhundleni se-incisor yebele;Amazinyo e-canine akhula cishe ezinyangeni ezingu-5 ukuze athathe indawo yamazinyo engane;

Ikati likhula amazinyo e-premolar cishe izinyanga ezi-2;I-premolars yesibili neyesithathu ikhula ezinyangeni ezi-4-6, futhi kancane kancane ishintshwe ngama-premolars ahlala njalo;I-posterior molar yokuqala ikhula ezinyangeni ezingu-4-5.Iminyaka eyinhloko yokushintsha izinyo yamakati cishe izinyanga ezingu-4-6.Ngalesi sikhathi, bangase balahlekelwe isifiso sokudla ngenxa yokuqaqamba kwamazinyo.

Ngemuva kokuba ikati lineminyaka engu-1 ubudala, ama-incisors alo aphansi aqala ukugqoka;Ngemva kweminyaka engu-7, amazinyo ekati ekati aqala ukuguga kancane kancane, futhi ama-incisors e-mandibular aba yindilinga;Ngemva kweminyaka engu-10, amazinyo angaphambili omhlathi ongenhla wekati angase awe, ngakho ungakwazi ukulungisa ukudla kwakho ngokuvumelana nezinguquko ze-te.
