ʻAno niho o nā ʻīlio

 ʻO ka mea maʻamau, he 42 mau mola nā ʻīlio a pau, akā nalo paha nā niho (oligodontia) i kekahi mau ʻano me nā waha pōkole, ka mea i kapa ʻia he brachycephals. Aia kekahi hemahema e like me ka nui o nā niho (polydontia). Hoʻohana ʻia ka inoa alphanumeric no ka hoʻopaʻa ʻana i ke ʻano niho o nā ʻīlio.

• ʻImi (Incisivi) – I
• Kanu - P
• Premolyar (Premolars) — P
• Mola (Molares) – M

Ma ke ʻano i kuhikuhi ʻia, ua like ke ʻano o ke ʻano niho o nā ʻīlio: ʻāwae luna 2M 4P 1C 3I 3I 1C 4P 2M – 20 niho āwae lalo 3M 4P 1C 3I 3I 1C 4P 3M – 22 niho niho, a hōʻike ka leka i ke ʻano o ka niho. : āwae luna M2, M1, P4, P3, P2, P1, I3, I2 I1, I1 I2 I3, C, P1, P2, P3, P4, M1, M2 iwi ā lalo M3, M2, M1 , P4, P3, P2 , P1, I3, I2, I1, I1, I2, I3, C, P1, P2, P3, P4, M1, M2, M3

Inā wehewehe ʻoe iā ia ma nā ʻōlelo maʻalahi, a laila aia ma ka iwi ā luna o ka ʻīlio he 6 ʻoki, 2 canine, 8 premolars, 4 molars, ma ka iwi lalo - 6 incisors, 2 canines, 8 premolars, 6 molars.

 Eia naʻe, ʻokoʻa ke ʻano o ke ʻano niho o nā niho waiū o nā ʻīlio, no ka mea. He ʻōiwi ka P1 premolar a ʻaʻohe ona deciduous antecedent. Eia kekahi, ʻaʻohe waiu mua o nā mola M. No laila, inā kākau ʻoe i ke ʻano niho o nā niho waiū, ua like ia me kēia: ʻO ke ʻano niho o nā ʻīlio ma mua o ka hoʻololi ʻana o nā niho penei: ʻauwae luna: 3P 1C 3I 3I 1C 3P – 14 niho āwae lalo: 3P 1C 3I 3I 1C 3P – 14 niho a i ʻole āwae luna : P4, P3, P2, C, I3, I2, I1 I1, I2, I3, C, P2, P3, P4 iwi ​​ā lalo: P4, P3, P2, I3, I2, I1 I1 , I2, I3, C, P2, P3, P4  

Hoʻololi o nā niho i nā ʻīlio

Hiki ke loli o nā niho i nā ʻīlio ma ka awelika ma ka makahiki 4 mahina. A ke hana nei ia ma ke ʻano penei: 

 'Ōlelo Aʻo: E ulu a mau loa nā premolars a me nā mola me ka ʻole o ka deciduous antecedents. Pono e hoʻomaopopo he mau hiʻohiʻona kekahi o nā ʻīlio. No ka laʻana, ʻaʻole ulu ka premolar. A i ʻole e ulu ka mola i ka wā e hoʻololi ai i nā niho, akā ʻaʻole e hāʻule ka waiū. I kēia hihia, pono ke kamaʻilio ʻana i kahi niho niho a hoʻohana i ka wehe ʻana i nā niho waiū. Hiki i ka polydontia a me ka oligodontia ke hōʻike i ka genetic imbalance, ka hānai pono ʻole a i ʻole nā ​​​​maʻi ma mua (rickets, nele o ka calcium), no ka mea, kokoke i nā ʻīlio āpau he 6 * 6 incisor formula ma ka pae genetic. He mea nui hoʻi ka nahu. Pono ka nui o nā ʻohana i ka nahu ʻokiʻoki, akā aia kekahi mau ʻano maʻamau ka nahu undershot (brachycephalic).

Nā ʻano niho o nā ʻīlio: ke kumu o kēlā me kēia ʻano niho

I kēia manawa e kamaʻilio hou e pili ana i ke kumu o kēlā me kēia ʻano niho. kālai – Hoʻolālā ʻia no ka nahu ʻana i nā ʻāpana liʻiliʻi o ka ʻiʻo. Nā ʻāpala - ua hoʻolālā ʻia e haehae i nā ʻāpana nui o ka ʻiʻo, a ʻo kā lākou hana koʻikoʻi he pale. Molars a me premolars - i hoʻolālā ʻia e ʻohi a wili i nā meaʻai. He mea pono e hoʻomaopopo i nā niho olakino e keʻokeʻo me ka ʻole o ka plaque a me ka ʻeleʻele. E like me ka makahiki o nā ʻīlio, ʻae ʻia ke kapa niho. Hiki ke hoʻohana ʻia e hoʻoholo i ka makahiki kokoke o ka ʻīlio.
