He aha nā niho deciduous?

ʻO nā niho Deciduous ka manawa kūhelu no nā niho pēpē, nā niho waiū, a me nā niho mua. Hoʻomaka ka hoʻomohala ʻana o nā niho Deciduous i ka wā embryonic a laila hoʻomaka pinepine e hele ma kahi o 6 mau mahina ma hope o ka hānau ʻana.

Aia ma ka maʻamau he 20 mau niho mua - 10 o luna a 10 mau haʻahaʻa. ʻO ka maʻamau, hū ka hapa nui o lākou i ka manawa o ke keiki ma kahi o 2½ mau makahiki.

Āhea e komo ai nā niho o kuʻu pēpē?

ʻO ka maʻamau, e hoʻomaka nā niho o kāu pēpē i ka wā ma kahi o 6 mau makahiki. ʻO ka niho mua e komo i loko ʻo ka incisor waena - waena, niho mua - ma ka iwi ā lalo. ʻO ka niho ʻelua e hiki mai ana ma kahi o ka mua: ʻo ka lua o ka incisor waena ma ka iwi ā lalo.

ʻO nā niho ʻehā e hiki mai ana ka maʻamau o nā incisors ʻehā o luna. Hoʻomaka ka hoʻomaka ʻana o lākou e hū ma kahi o ʻelua mau mahina ma hope o ka komo ʻana o ka niho like ma ka iwi ā lalo.

ʻO ka lua o nā molars ka hope loa o nā niho deciduous 20, ke hele mai i ka wā o kāu pēpē ma kahi o 2½ mau makahiki.

Heʻokoʻa nā kānaka āpau: Loaʻa i kekahi i ko lākou niho pēpē ma mua, loaʻa i kekahi ma hope. Inā he mau nīnau a hopohopo paha kāu e pili ana i nā niho mua o kāu keiki, e nīnau i kāu kauka niho.

Hōʻike ka American Academy of Pediatric Dentistry i ka huakaʻi niho mua o kāu pēpē ma mua o ka hiki ʻana i ka makahiki 1, ma waena o 6 mau mahina ma hope o ka puka mua o ko lākou niho mua.

Āhea hiki mai nā niho paʻa?

E pani ʻia nā niho pēpē he 20 o kāu keiki me 32 mau niho mau, a makua paha.

Hiki iā ʻoe ke manaʻo i kāu keiki e hoʻomaka e nalo i ko lākou niho deciduous ma kahi o ka makahiki 6. ʻO nā mea mua e hele ka mea maʻamau ka mea i komo i loko: nā incisors kikowaena.

Lilo i kāu keiki ka niho hope loa, ka cuspid a i ʻole ka molar ʻelua, ma kahi o 12 mau makahiki.

Pehea nā niho deciduous mai nā niho makua?

ʻO nā ʻokoʻa ma waena o nā niho mua a me nā niho mākua:

• ʻO ʻEnamelia ʻO ka enamel ka papa o waho paʻakikī e pale i kou mau niho mai ka palaho. ʻOi ka lahilahi o nā niho kumu.
• Waihoʻoluʻu. ʻO nā niho Deciduous ke nānā keokeo. Hiki ke hāʻawi ʻia kēia i ka enamel lahilahi.
• Nui ʻOi aku ka liʻiliʻi o nā niho mua ma mua o nā niho mau o nā mākua.
• Kinona. Hele pinepine mai nā niho paʻa mua me nā puʻupuʻu e ʻānai i ka manawa.
• Mole. ʻOi aku ka pōkole a me ka lahilahi o nā aʻa o nā pēpē pēpē no ka mea ua hoʻolālā ʻia e hāʻule i waho.

Hoʻomaka ka hāʻule ʻana o nā niho deciduous ma kahi o 6 mau makahiki e hoʻololi ʻia e 32 mau niho makua makua.
