Amazinyo asisiza ukuthi silume ukudla, sibize amagama ngendlela efanele, futhi sigcine isimo sobuso bethu sesakhiwo.Izinhlobo ezahlukene zamazinyo emlonyeni zidlala indima ehlukene ngakho-ke ziza ngezindlela ezihlukahlukene nobukhulu.Ake sibheke ukuthi yimaphi amazinyo esinawo emilonyeni yethu nokuthi yiziphi izinzuzo angaletha.
Uhlobo lwamazinyo
Ukuma kwamazinyo kuvumela ukuba enze umsebenzi othile ohlelweni lokuhlafuna ukudla.
8 ama-incisors
Amazinyo angaphambili kakhulu emlonyeni abizwa ngokuthi ama-incisors, amane phezulu namane, uma esewonke ayisishiyagalombili.Ukuma kwama-incisors kuyisicaba futhi mncane, kufana neshizolo.Bangaluma ukudla kube yizicucu ezincane lapho uqala ukuhlafuna, bakusize uphimisele amagama ngendlela efanele lapho ukhuluma, futhi ugcine izindebe zakho nokwakheka kobuso bakho.
Amazinyo abukhali eduze kwama-incisors abizwa ngokuthi ama-canines, amabili phezulu namabili phansi, uma esewonke amane.Amazinyo e-canine made futhi akhombe ngendlela futhi adlala indima ebalulekile ekuhlinzeni ukudla, njengenyama, ngakho izilwane ezidla inyama ngokuvamile zinamazinyo e-canine athuthukile.Hhayi amabhubesi namahlosi kuphela, kodwa nama-vampires akule noveli!
8 ama-premolars
Amazinyo amakhulu, athambile eduze kwamazinyo e-canine abizwa ngokuthi ama-premolars, anendawo eyisicaba kanye nemiphetho ephakanyisiwe, okuwenza afanelekele ukuhlafuna nokugaya ukudla, ukudla okulumayo kuze kube usayizi ofanele ukugwinya.Abantu abadala abavuthiwe ngokuvamile banama-premolars ayisishiyagalombili, amane ohlangothini ngalunye.Izingane ezincane azinawo amazinyo e-premolar futhi ngokuvamile aziqhumi njengamazinyo ahlala njalo kuze kube yilapho sezineminyaka eyi-10 kuya kweyi-12 ubudala.
Ama-Molars amazinyo amakhulu kunawo wonke.Zinendawo enkulu, eyisicaba enonqenqema oluphakanyisiwe olungasetshenziswa ukuhlafuna nokugaya ukudla.Abantu abadala banama-molars angapheli angu-12, angu-6 phezulu na-6 phansi, futhi angu-8 kuphela kuma-papillae ezinganeni.
Amazinyo okugcina avelayo abizwa ngokuthi amazinyo okuhlakanipha, aziwa nangokuthi amazinyo esithathu okuhlakanipha, avame ukuqhuma phakathi kweminyaka eyi-17 nengama-21 futhi atholakala engxenyeni engaphakathi yomlomo.Nokho, abanye abantu abanawo wonke amazinyo okuhlakanipha amane, futhi amanye amazinyo okuhlakanipha agqitshwa ethanjeni futhi awalokothi aqhume.
Njengoba izingane zikhula, amazinyo ahlala njalo aqala ukuqhuma ngaphansi kwamazinyo ezingane.Njengoba amazinyo ahlala ekhula, izimpande zamazinyo omntwana zimunca kancane kancane izinsini, okubangela ukuba amazinyo omntwana axege futhi awe, okwenza amazinyo angapheli.Izingane ngokuvamile ziqala ukushintsha amazinyo lapho zineminyaka eyisithupha ubudala futhi ziqhubeke zize zibe neminyaka engaba ngu-12 ubudala.
Amazinyo ahlala njalo ahlanganisa ama-incisors, ama-canines, ama-premolars, nama-molars, kuyilapho amazinyo ezingane engenawo ama-premolars.Amazinyo athatha indawo yama-molars avuzayo abizwa ngokuthi ama-premolars okuqala kanye nesesibili.Ngesikhathi esifanayo, i-mandible izoqhubeka ikhula ngesikhathi sokuthomba, idale isikhala esiningi se-molar.I-molars yokuqala ehlala njalo ivame ukuqhuma lapho eneminyaka eyisithupha, kanti i-molars yesibili ehlala njalo ivame ukuvela cishe eminyakeni eyi-12.
Igobolondo lesithathu elihlala njalo, noma izinyo lobuhlakani, ngokuvamile aliqhumi kuze kube yiminyaka eyi-17 kuye kwengama-25, kodwa ngezinye izikhathi lingase lingaveli, libe izinyo elithintekile, noma lingaqhumi nhlobo.
Kafushane, kunamazinyo ezingane angama-20 namazinyo angama-32 ahlala njalo.
