ʻAʻole hānai ʻia nā pōpoki a me nā ʻīlio a nā hoaaloha mai ka wā ʻōpiopio, no laila makemake maoli lākou e ʻike i ko lākou mau makahiki? ʻO ka ʻai ʻana i ka meaʻai no nā pōpoki a me nā ʻīlio? A i ʻole e ʻai i ka ʻīlio makua a me ka pōpoki? ʻOiai inā kūʻai ʻoe i pipi mai ka wā ʻōpiopio, noʻonoʻo mau ʻoe i ka makahiki o ka holoholona, ​​ʻo 2 mahina a 3 mau mahina paha? Ma nā halemai, hoʻohana mau mākou i nā niho e hoʻoholo mua i ka makahiki o nā holoholona.

He ʻokoʻa koʻikoʻi nā niho ma muli o ka meaʻai a lākou e ʻai ai a me kā lākou hana hānai ʻana, a me ka nui o nā mea pāʻani wili niho a me nā meaʻai i hoʻohana ʻia. No laila, ma ka ʻōlelo maʻamau, pololei lākou no nā ʻīlio a me nā pōpoki, ʻoiai no nā ʻīlio makua, ʻoi aku ka nui o ka deviation. ʻOiaʻiʻo, ʻo ka mea i kapa ʻia ʻo deviation he haʻahaʻa. He mea maʻamau i ka ʻīlio 5 makahiki ka ʻai ʻana i nā iwi a loaʻa nā niho e ʻaʻahu a uhae like me ka ʻīlio 10 makahiki, akā ʻaʻole hiki iā ʻoe ke hālāwai me kahi ʻīlio 10 makahiki me nā niho like he ilio 5 makahiki. Ua ʻike au i kekahi mea mālama holoholona nāna i lawe mai i kahi holoholona lauoho gula i ʻōlelo ʻia he 17 mau makahiki. He mea nui kēlā, a he mea pono e hoʻoholo i kona mau makahiki a me kona kūlana kino no ka mālama ʻana. ʻO ka wehe ʻana o kona waha e ʻike i kona mau niho, ua manaʻo ʻia he 7 makahiki wale nō. Ua hoʻomanaʻo hewa paha wau i ka makahiki o kona mau kūpuna?

ʻOiaʻiʻo, ʻo ka nānā ʻana i nā niho i ka wā kamaliʻi hiki ke hōʻike i nā maʻi he nui o nā holoholona, ​​​​e like me ka hemahema o ka calcium a me nā niho lālani pālua. No laila he mea nui e aʻo pehea e nānā ai i ka ulu ʻana o nā niho, e hoʻoholo i ko lākou mau makahiki a me ke olakino.

Hoʻomaka nā ʻīlio e ulu i nā niho deciduous mai 19 a 20 mau lā ma hope o ka hānau ʻana; I ka 4-5 mau pule, ua like ka lōʻihi o ka umauma mua a me ka lua (incisors); I ka makahiki 5-6, ua like ka lōʻihi o ka niho ʻoki ʻekolu; No nā ʻīlio he 8 mau pule, ua ulu pono nā ʻoki āpau a pau, a ua keʻokeʻo nā niho o ka umauma a lahilahi a ʻoi;

I loko o nā mahina 2-4 ma hope o ka hānau ʻana, hoʻololi mālie nā ʻīlio i ko lākou mau niho deciduous, hoʻoheheʻe a hoʻoulu i nā ʻoki hou mai ka ʻoki mua; E hoʻomaka ana mai ka makahiki 5-6 mau mahina, e hoʻololi i ka lua a me ke kolu o nā incisors a me nā canines; I ka makahiki 8-12 mahina, ua pani ʻia nā molar a pau me nā niho mau (permanent niho). He keʻokeʻo a ʻālohilohi nā niho paʻa, a ʻo nā ʻāʻī he ʻano kikoo. Inā ʻike ʻia ka melemele, hōʻike ia i ka tartar;

I ka 1.5 a hiki i ka 2 makahiki o ka ilio, ua mae ka piko nui o ka iwi mua (niho mua) a ua pulupulu me ka piko li'ili'i, i kapa 'ia he peak wear out; I ka makahiki 2.5, ua pau ka piko o ka lua o ka mandibular incisor (niho waena); I ka makahiki 3.5, ua pau ka piko o ka maxillary incisors; I ka makahiki 4.5, ua pau ka piko o ka niho maxillary waena; Hoʻopau ʻia nā makahiki ʻōpio o nā ʻīlio, a ʻaʻole pili nā loli o nā niho i kēia manawa e nā kumu makahiki e like me ka meaʻai a lākou e ʻai ai, no laila ke hele mālie nei lākou.

E hoʻomaka ana mai ka makahiki 5, ʻo ke kolu o ka incisor a me ka ʻīlio ʻīlio ma ka lae haʻahaʻa ua luhi iki (ʻaʻole i palahalaha), a ʻo ka ʻoki ʻoki mua a me ka lua he ʻano ʻehā; I ka makahiki 6, ua paʻa iki ke kiʻekiʻe o ke kolu o ka maxillary incisor, a ʻo nā niho canine he pōpō a poepoe; I ka makahiki 7, ua hoʻohana ʻia nā ʻāpana mandibular o nā ʻīlio nui i ke aʻa, me kahi ʻili elliptical longitudinal; I ka 8 o kona mau makahiki, ua aahuia na manamana lima o ka ilio nui a miki i mua; I ka makahiki 10, he elliptical longitudinally ka ʻili o ka mandibular second incisor a me ka maxillary incisor; He 10-12 mau makahiki ke ola o na ilio nui a he mea ma'amau ka poho o ka niho, ma muli o ke aahu a me ka waimaka;

I ka makahiki 16, ua lōʻihi ke ola o kahi ʻīlio liʻiliʻi, a i ʻole he ʻīlio ʻelemakule maʻamau me ka nalo ʻana o nā ʻoki, nā niho ʻīlio ʻaʻole piha, a me nā niho melemele like ʻole; I ka makahiki 20, hāʻule nā ​​niho ʻīlio a ʻaneʻane ʻaʻohe niho i loko o ka waha. ʻO ka ʻai ʻana he meaʻai wai.

Ke hoʻohālikelike ʻia me ka ʻīlio pinepine ʻana i ko lākou mau niho ma nā mea paʻakikī, he mea paʻakikī ke hoʻoholo i ka makahiki ma muli o ka ʻaʻahu ʻana o ka niho, ulu mau nā niho o nā pōpoki a aneane hiki ke hoʻohana ʻia ma ke ʻano he kumu maikaʻi loa no ka hoʻoholo ʻana i ka makahiki.

ʻO nā niho ʻīlio o nā pōpoki he lōʻihi, ikaika a ʻoi, me ke aʻa a me ka piko. Ke pani ʻia ka waha waha, aia nā niho ʻīlio luna ma ka ʻaoʻao hope o waho o nā niho ʻīlio haʻahaʻa. Aia ka hakahaka ma hope o nā niho ʻīlio, ʻo ia ka molar mua. He liʻiliʻi ka mua mua, ʻoi aku ka nui o ka premolar lua, a ʻo ke kolu ka premolar ka nui loa. He ʻehā mau ʻaoʻao niho o ka mua o luna a me lalo, ʻoi aku ka nui a me ka ʻoi o ka piko o waena, hiki ke haehae i ka ʻiʻo. No laila, kapa ʻia ʻo ia he niho māwae.
