Ukuhlaselwa kwabantwana kuqala ngokuqhelekileyo kwiminyaka engama-6 ubudala, kodwa ngaphakathi kwemida yeendlela eziphambene nokuphambuka kwangaphambili okanye ukuqhuma komva kunokwenzeka. Ukuba umntwana akanalo inyo elilodwa ngonyaka, kuyafaneleka ukumbona ugqirha-oku kungabonakalisa ingxaki yokuxilonga kunye nezixhobo. Mane uqaphele ukuba umntwana uzalelwe ngamazinyo okanye avela kwiinyanga ezintathu zokuqala zobomi.
Amazinyo aphuphuma kumabini athile ahlukeneyo - kumhlathi ophezulu nangaphantsi. Ngomnyaka, njengomthetho, sele unamazinyo angu-8. Iifowuni ezithintekayo kubantwana ziqala malunga neenyanga ezili-16-20. Okokuqala, iimfengane zomntwana emlonyeni ongaphantsi, kwaye emva koko emlonyeni omkhulu, ukhuphuke. Amazinyo okuqala omntwana ngokubanzi akulula ngaye kunye nabazali bakhe, kodwa iifeng zikhula ngokukhethekileyo.
Iimvumba ezithintekayo kubantwana: iimpawu
- umntwana uyaba ngongqoqo, aphumule, alala kakuhle;
- nciphisa ukutya. Umntwana akufanele atyiswe ngamandla, kodwa kuyimfuneko ukumnika isiselo esininzi;
- umntwana uhlala esondeza izandla kunye nezinto ezahlukeneyo emlonyeni wakhe;
- Umntwana ugcwele umquba, onokubangela ukucaphuka kwesikhumba emlonyeni;
- maxa wambi ngenye inxalenye yezinyo ezikhuphayo ziindawo zokuhamba kunye nokubomvu;
- Ngaphambili kwakukholelwa ukuba ngenxa yokuvuvukala kweentsontsho emva kwangoko, kufaka phakathi i-fangs, isifo sohudo singenzeka. Nangona kunjalo, uphando olutshanje luye lwabonisa ukuba ukuphazamiseka kwesihlalo akuhambelani nenkqubo yokubonakala kwamazinyo kwaye kubonisa ukuphulwa kwesondlo okanye ukugaya;
- ukwanda kweqondo lokushisa komzimba ukuya kuma-degrees ama-38 - abazali bahlala bekopela ngamazinyo ngaphandle kwesizathu kunyuka kwindleko ebushushu kumntwana. Kodwa ezi nkqubo zinxulumene ngqo ngokukhawuleza - ngexesha lokuqubuka kwamazinyo, ukukhuseleka kubuthakathaka kwaye amathuba okugula ayenyuka.
Ngaloo ndlela, ukuba inkqubo yokuhamba ihamba nobushushu obuphezulu,
Ziya kutshintshwa nini iintlungu kubantwana?
Ukususela kwiminyaka engama-6 ukuya ku-7, amazinyo amantombazana aphantsi kancane, anikezela amazinyo angunaphakade. Ukukhula kwamazinyo amatsha kwenzeka ngokohlobo olufanayo njengamazinyo obisi - okokuqala kuqala i-incisors yangaphambili, emva koko i-lateral. Iimfesane eziqhubekayo kubantwana zivela xa iimveliso zobisi ziphela - emva kweminyaka eyi-8-9. Ukulungelelaniswa kwamathambo amazinyo kugqityiwe malunga neminyaka eyi-11 ukuya kwe-12, kwaye uneminyaka eyi-17-25 i-molars yokugqibela-okubizwa ngokuba ngamazinyo obunzima-kukhula.
