ʻO ka incisor (i loaʻa mai ka huaʻōlelo incision, mai ka Latin ʻO ka ʻoki, incise) he ʻano niho, aia i loko o ka waha waha a hoʻohana ʻia e ʻoki i ka meaʻai.

Aia i ka niho kanaka he ewalu incisors i puunaueia penei:

• ʻElua ʻoki waena o luna
• ʻElua ʻaoʻao ʻaoʻao o luna
• ʻElua ʻoki waena haʻahaʻa
• ʻElua ʻāpana ʻaoʻao haʻahaʻa

'O ia ka po'o niho ma ke alo o ka maxilla a me ka ma'i, e pili ana i ka iwi ā luna a me lalo.

ʻO nā incisors nā niho mua i ʻike ʻia a he kuleana koʻikoʻi ko nā niho aesthetics. ʻO lākou ka poʻe i mua o nā ʻeha kino o ka wā kamaliʻi.

Hoʻohana ʻia ka huaʻōlelo "nā niho hauʻoli" e kuhikuhi i ka mamao ma waena o nā ʻāpana medial luna ʻelua. Ua kapa ʻia kēia mamao he "diastema".

Ua like pinepine ka waena waena a me ka ʻaoʻao lalo.

Aia i loko o ka waha waha a ma ke kihi o ka piko niho, he 4 mau canine, i puunaueia penei:

• ʻelua mau ʻīlio luna, aia ma kēlā ʻaoʻao kēia ʻaoʻao o nā ʻoki luna
• ʻelua mau ʻīlio haʻahaʻa, aia ma kēlā ʻaoʻao kēia ʻaoʻao o nā ʻāpana haʻahaʻa.

ʻO nā ʻīlio he niho ʻoi me ʻelua mau ʻaoʻao ʻoi. Mahalo i kēia a me ko lākou ʻano kiko, hoʻohana ʻia nā ʻīlio e ʻoki i nā meaʻai paʻa e like me ka ʻiʻo. He niho ʻokoʻa ia mai nā niho ʻē aʻe mai ka hoʻomaka ʻana o ka laina mammalian.

Loaʻa i nā carnivores kahi ʻīlio i hoʻomohala ikaika ʻia, akā ʻo ka kūpuna maʻamau i nā ʻohana carnivores o kēia manawa, ʻo ka Miacis, kahi mammal prehistoric liʻiliʻi o 60 miliona mau makahiki, he 44 mau niho a me nā canine maikaʻi ʻole.

Kapa ʻia kēia mau niho i kekahi manawa he "niho o ka maka" no ka mea, hiki i ko lākou mau aʻa lōʻihi loa a hiki i ka ʻāpana o ka maka. ʻO kēia ke kumu e hiki ai ke hoʻouna ʻia kahi maʻi ma nā canine luna i kekahi manawa i ka ʻāpana orbital.

ʻO ka premolar (molar, mai Latin molaris, loaa mai ʻulala, ʻo ia hoʻi ka huila wili) he ʻano niho i hoʻohana nui ʻia no ka wili ʻana i ka meaʻai.

Hoʻonoho ʻia nā premolars ma waena o nā ʻīlio, aia ma ke alo o ka piko niho, a me nā molars, aia ma ka hope. Aia i ka niho kanaka he ewalu mau premolar i puunaueia penei:

• ʻehā premolars luna, ʻelua o ia mau mea e kau ʻia ma kēlā me kēia iwi ā luna.
• ʻehā mau premolars lalo, ʻelua o ia mau mea e kau ʻia ma kēlā me kēia iwi ā hapa ma lalo.

ʻO nā niho mua he mau niho cubic liʻiliʻi ke ʻano, he lei aliʻi maʻamau me ʻelua mau ʻōpū poepoe.

ʻO ka molar (mai ka Latin molaris, loaa mai ʻulala, ʻo ia hoʻi ka huila wili) he ʻano niho i hoʻohana nui ʻia no ka wili ʻana i ka meaʻai.

Aia i loko o ka waha waha, ʻo nā molars nā niho hope loa o ka piko niho. ʻO ka niho kanaka he 12 mau mola mau i puʻunaue ʻia penei:

• ʻeono mau molar luna, ʻekolu o lākou i kau ʻia ma kēlā me kēia āpana ā luna a hāhai i nā premolars luna.
• ʻeono mau molar lalo, ʻekolu o lākou e kau nei ma kēlā me kēia iwi ā hapa ma lalo a ukali i nā premolars lalo.

ʻO nā mola ʻekolu, kapa ʻia nā niho akamai, he kumu ia o nā pilikia a me ka ʻeha. ʻO ka mea nui, hiki iā lākou ke hana i nā maʻi a i ʻole ka neʻe ʻana o nā niho.
