Iikati kunye nezinja zabahlobo abaninzi azikhuliswanga zisebancinci, ngoko zifuna ngokwenene ukwazi ukuba zingakanani?Ingaba kukutya amantshontsho namantshontsho?Okanye ukutya inja yabantu abadala kunye nekati?Nokuba uthenga isilwanyana sasekhaya usemncinci, usazibuza ukuba isilwanyana sineminyaka emingaphi, ngaba sineenyanga ezi-2 okanye iinyanga ezi-3 ubudala?Ezibhedlele, siqhele ukusebenzisa amazinyo ukumisela kwangaphambili ubudala bezilwanyana zasekhaya.

Amazinyo anomahluko obalulekileyo ngokuxhomekeke kukutya akutyayo kunye nemikhwa yawo yokutya, kunye nobungakanani bamazinyo okucola amathoyizi kunye nokutya okusetyenzisiweyo.Ngoko ke, ngokuqhelekileyo, zichanekile kubantwana kunye neekati, ngelixa izinja ezikhulileyo, ukuphambuka kunokubaluleka.Kakade ke, oko kubizwa ngokuba kukutenxa kukwaphakathi.Iqhelekile into yokuba inja eneminyaka emi-5 ubudala itye amathambo ibe namazinyo anxiba nakrazula afana nenja eneminyaka eli-10 ubudala, kodwa awukwazi ukudibana nenja eneminyaka eli-10 ubudala enamazinyo afana nala. inja eneminyaka emi-5 ubudala.Ndakha ndadibana nomnini wesilwanyana esiza nesilwanyana esineenwele ezigolide esithi sineminyaka eli-17 ubudala.Yayiyinto enkulu leyo, kwaye kwakuyimfuneko ukumisela ubudala bayo kunye nemeko yomzimba ukuze unyango.Ivula umlomo wayo ukuze ibone amazinyo ayo, kwakuqikelelwa ukuba yayineminyaka esi-7 kuphela ubudala.Ngaba ndikhumbula iminyaka yootatomkhulu bayo ngokungalunganga?

Kakade ke, ukujonga amazinyo ebuntwaneni kunokutyhila izifo ezininzi zezilwanyana zasekhaya, ezinjengokunqongophala kwecalcium kunye namazinyo amiqolo emibini.Ngoko kubalulekile ukufunda indlela yokuqwalasela ukuphuhliswa kwamazinyo, ukumisela iminyaka kunye nempilo yabo.

Izinja ziqala ukuphuhlisa amazinyo ukusuka kwi-19 ukuya kwiintsuku ezingama-20 emva kokuzalwa;Kwiiveki ezi-4-5 ubudala, i-incisors yokuqala neyesibini yesifuba inobude obulinganayo (i-incisors);Kwiiveki ezi-5-6 ubudala, izinyo lesithathu lokusika linobude obulinganayo;Kwiiveki ezi-8 zabantwana, zonke ii-incisors zebele zikhule ngokupheleleyo, kwaye amazinyo esifuba amhlophe kwaye anqabile kwaye abukhali;

Ngethuba leenyanga ezi-2-4 emva kokuzalwa, izinja ngokuthe ngcembe zithatha amazinyo azo, zikhupha kwaye zikhule ama-incisors amatsha kwi-incisor yokuqala;Ukususela kwiinyanga ezi-5-6, buyisela i-incisors yesibini neyesithathu kunye ne-canines;Ngeenyanga ezi-8-12, zonke iimolars zitshintshwa ngamazinyo asisigxina (amazinyo asisigxina).Amazinyo asisigxina amhlophe kwaye acwebezelayo, kwaye i-incisors ine-protrusions ecacileyo.Ukuba i-yellow ibonakala, ibonisa i-tartar;

Xa inja ineminyaka eyi-1.5 ukuya kwe-2 ubudala, incopho enkulu ye-mandibular incisor yokuqala (izinyo langaphambili) igugile kwaye igungxulwe kunye nencopho encinci, ebizwa ngokuba yi-peak wear out;Kwiminyaka eyi-2.5, incopho ye-mandibular incisor yesibini (izinyo eliphakathi) igugile;Kwiminyaka eyi-3.5, incopho ye-incisors ye-maxillary igugile;Ngeminyaka eyi-4.5, incopho yezinyo le-maxillary ephakathi igugile;Iminyaka yezinja yeshumi elivisayo ifikelela esiphelweni, yaye ukuguquka kwamazinyo ngeli xesha akuchatshazelwa zizinto zobudala njengokutya ezikutyayo, ngoko ngokuthe ngcembe ziya zichaneka.

Ukususela kwiminyaka emi-5, i-incisor yesithathu kunye nencani ye-canine kwibunzi elingaphantsi ligqithise kancane (elingacwangciswanga), kwaye i-incisors yokuqala neyesibini i-rectangular shape;Ngeminyaka eyi-6, i-peak of the third maxillary incisor igugile kancinci, kwaye amazinyo e-canine anqabile kwaye ajikeleze;Ngeminyaka eyi-7, i-mandibular incisors yezinja ezinkulu zigqitywe kwingcambu, kunye ne-longitudinal elliptical surface;Kwiminyaka eyi-8, i-mandibular incisors yenja enkulu iyanxitywa kwaye ijonge phambili;Kwiminyaka eyi-10, indawo yokunxiba ye-mandibular yesibini incisor kunye ne-maxillary incisor i-elliptical longitudinally;Izinja ezinkulu zihlala ziphila iminyaka eyi-10-12 kwaye azifane zifumane ukulahleka kwamazinyo, ngokuqhelekileyo ngenxa yokuguga okukhulu kunye nokukrazula;

Kwiminyaka eyi-16, inja encinci inobomi obude, okanye kunoko inja ekhulileyo eqhelekileyo ene-incisors elahlekileyo, amazinyo e-canine angaphelelanga, kunye namazinyo aqhelekileyo angalingani;Ngeminyaka eyi-20, amazinyo e-canine awela kwaye kwakungekho phantse amazinyo emlonyeni womlomo.Ukutya yayikukutya okumanzi.

Xa kuthelekiswa nezinja zisoloko zisila amazinyo kwizinto eziqinileyo, nto leyo eyenza kube nzima ukumisela ubudala ngenxa yokuguga kwamazinyo, amazinyo ekati akhula rhoqo kwaye aphantse asetyenziswe njengeyona khrayitheriya yokugweba iminyaka.

Amazinyo e-canine eekati made, anamandla kwaye abukhali, anengcambu kunye nencam.Xa i-cavity yomlomo ivaliwe, amazinyo aphezulu e-canine abekwe kwicala elingasemva lamazinyo angaphantsi kwe-canine.Kukho umsantsa emva kwamazinyo e-canine, eyi-molar yangaphambili.I-premolar yokuqala incinci ngokwentelekiso, eyesibini i-premolar inkulu, kwaye eyesithathu i-premolar yeyona inkulu.Zombini ii-premolars ezingasentla nezisezantsi zinencam yamazinyo ezine, incam yezinyo eliphakathi inkulu kwaye ibukhali, enokukrazula inyama.Ngoko ke, ikwabizwa ngokuba lizinyo elicandekileyo.
