Dental formula yembwa

 Kazhinji, imbwa dzose dzine 42 molars, asi dzimwe mhando dzine mazamu mapfupi, anonzi brachycephals, anogona kunge asina mazino (oligodontia). Iko kunewo kukanganisa kwakadaro sekuwedzera kwenhamba yemazino (polydontia). Chirevo chealphanumeric chinoshandiswa kurekodha maitiro emazino embwa.

• Incisors (Incisivi) - I
• Caninus - P
• Premolyar (Premolars) - P
• Molars (Molares) - M

Mune fomu yakatemwa, mazino emazino embwa anoita seizvi: shaya yepamusoro 2M 4P 1C 3I 3I 1C 4P 2M - 20 mazino ezasi shaya 3M 4P 1C 3I 3I 1C 4P 3M - 22 mazino mazino, uye tsamba inoratidza rudzi rwezino. : shaya yepamusoro M2, M1, P4, P3, P2, P1, I3, I2 I1, I1 I2 I3, C, P1, P2, P3, P4, M1, M2 shaya yezasi M3, M2, M1 , P4, P3, P2 , P1, I3, I2, I1, I1, I2, I3, C, P1, P2, P3, P4, M1, M2, M3

Kana iwe ukaitsanangura nemashoko ari nyore, ipapo mushaya yepamusoro yembwa pane 6 incisors, 2 canines, 8 premolars, 4 molars, muzasi meshaya - 6 incisors, 2 canines, 8 premolars, 6 molars.

 Zvisinei, maitiro emazino emukaka mazino embwa anotarisa zvakasiyana, nokuti. iyo P1 premolar ndeyemuno uye haina deciduous antecedent. Zvakare, M molars haina ma antecedents emukaka. Nokudaro, kana iwe ukanyora maitiro emazino emazino emukaka, zvinoratidzika sezvizvi: Mucherechedzo wemazino embwa pamberi pekuchinja kwemazino ndeaya anotevera: shaya yepamusoro: 3P 1C 3I 3I 1C 3P - 14 mazino pasi shaya: 3P 1C 3I 3I 1C 3P - 14 mazino kana shaya yepamusoro : P4, P3, P2, C, I3, I2, I1 I1, I2, I3, C, P2, P3, P4 shaya yezasi: P4, P3, P2, I3, I2, I1 I1 , I2, I3, C, P2, P3, P4  

Kuchinja kwemazino mumbwa

Kuchinja kwemazino mumbwa kunoitika paavhareji pazera remwedzi mina. Uye zvinoitika nenzira inotevera: 

 Ongorora: Premolars uye molars isina deciduous antecedents inokura uye inogara nekusingaperi. Zvakakosha kucherechedza kuti mamwe marudzi embwa ane maitiro. Semuenzaniso, iyo premolar haina kukura. Kana kuti mazino anomera panochinja mazino, asi iwo mukaka haadonha. Muchiitiko ichi, zvakakosha kuonana nachiremba wemazino uye kushandisa kubviswa kwemazino emukaka. Polydontia uye oligodontia inogona kuratidza kusaenzana kwemajini, kudya kusina kunaka kana zvirwere zvekare (rickets, kushaya calcium), nokuti inenge imbwa dzose dzine 6 * 6 incisor formula pane genetic level. Uyewo kuruma kunokosha. Mhuka zhinji dzinofanirwa kunge dziine chigero, asi kune dzimwe mhando dzekurumwa kwepasi kwakajairika (brachycephalic).

Dental formula yembwa: chinangwa chemhando yega yega mazino

Iye zvino ngatitaurire zvakawanda pamusoro pechinangwa chemhando imwe neimwe yemeno. vematombo - Yakagadzirirwa kucheka zvidimbu zvidiki zvenyama. fangs - dzakagadzirirwa kubvarura zvidimbu zvakakura zvenyama, uye basa ravo rinokosha rinodzivirira. Molars uye premolars - yakagadzirirwa kupwanya nekukuya mafiibhi echikafu. Zvinokosha kucherechedza kuti mazino ane utano anofanira kuva machena pasina plaque uye kusviba. Sezvo imbwa dzichikura, kupfeka mazino kunogamuchirwa. Inogona kutoshandiswa kuona zera reimbwa.
