Kutheni kufuneka ukuba fluoridation amazinyo?

Njengoko yokusebenza ibonisa, bilshinstvo abantu abeza wamazinyo kunye ingxaki ethile, kufuneka ukomeleza wayesebenzisa izinyo. Yayibubungqina eziphambili kakhulu ekomelezeni - oku kwandisa ubuntununtunu kunye nokuthintela yidityaniso. Le nto kufuneka ngenxa yokunqongophala kwezinto zomzimba kuyimfuneko ukuze inqaba lwawo, - calcium fluoride.

Inkqubo kakhulu luncedo kule meko ke fluorination kwamazinyo - sezisombululo ukutyabeka kunye lacquer kunye nomxholo high fluorine. Le nkqubo ivumela ukuba kuwanelisa amazinyo ion fluorine, nto leyo esithintelayo yidityaniso kunye ukubola kwamazinyo.

Fluoridation kwamazinyo yeentlobo ezimbini: ilula kwaye mihla nezinempumelelo fluoridation enzulu.

Uhlobo zokuqala ngokubanzi kusetyenziswa phantse zonke iinkonzo zamazinyo yaye elula ngokupheleleyo. Simple izinyo fluoridation lwenziwa ngeendlela ezimbini:

- usebenzisa "amacephe" umntu - okuvelayo zamazinyo eyenziwe wax kwaye ezaliswe ichiza fluorine aqulethe. Loo "icephe" ziyasetyenziswa amazinyo ukuze imiz 10-15. Ukuze kufikelelwe isiphumo oyifunayo kuya kufuneka aphinde inkqubo izihlandlo ezili-10, oko kukuthi, amaxesha 10 ukuya kutyelela wamazinyo;

- usebenzisa lacquer olusetyenziswa ibhrashi ekhethekileyo kumphezulu amazinyo. Le ndlela fluoridation inciphise inani utyelelo wamazinyo amaxesha 3-4;

Xa fluorination elula fluoro na mayifakwe kubunzulu Pore, njengoko kunjalo fluorination enzulu.

fluoridation anzulu amazinyo ezisekelwe amalungiselelo ukusetyenziswa emalzapechatyvayuschih.

Phambi kokuba nkqubo wenziwe ukuba fluorination olunzulu Ukucoca amazinyo welitye kunye kwakubhalwe bese komiswa usebenzisa umoya ezifudumeleyo ngokusebenzisa amazinyo inshorensi tampon ulwelo emalzapechatyvayuschey. Emva kwemizuzu embalwa kamva amazinyo etshile kwakhona, ngoko sebenzisa le tampon isale nesisombululo calcium hayidroksayidi zezobhedu.

Ngexesha yamazinyo inkqubo emalzapechatyvayuschey ukutyabeka elulwelo pores kulo izinyo wayesebenzisa kutshatyalaliswa ingena fluoro, kunye calcium hayidroksayidi kwi zokwaleka ziikristale zobhedu benziwa gel of silicic acid kunye calcium fluoride. Ezi ziikristale ukungena na, nkqu pores amancinci lo lwawo, nengqwalaselo fluorine kule izihlandlo ezihlanu ngaphezulu kunokuhlala fluorination elula.

Ngelishwa, ukulahlekelwa amazinyo, fluoride kunye neengxaki ezinxulumene nje kuphela abantu abadala. ERashiya, Ngokwezibalo, yidityaniso kuba sesithathu abantwana abaneminyaka iminyaka elishumi elinambini. Oku kwenzeka ngenxa yokuba kwilizwe lethu umkhwa encinane oqhelekileyo yothintelo yidityaniso. Ngelo xesha eYurophu, apho fluoridation amazinyo ubisi - nkqubo eliqhelekileyo, 1 kuphela umntwana ngaphandle kwekhulu na okanye unengxaki yidityaniso. Abantwana kunye nabantu abadala, kuyenzeka ukuba wenze zombini fluoridation elula enzonzobila. Ngenxa yale nkqubo lo lwawo lube nzima kakhulu snizhet izinyo ubuntununtunu kunye nengozi yidityaniso asakhasayo.

Kungenjalo, ngokuba ekomelezeni zamazinyo wayesebenzisa yobisi ayesebenzisa silvering. Le ndlela sikuko yokuba amazinyo kwisisombululo isicelo, leyo iqulathe zesilivere. Le fom isisombululo kwi amazinyo ezingabonakaliyo umboniso, nto leyo ithintela uphuhliso kunye ukuyilwa yidityaniso. Kufuneka iqondwe ukuba le nkqubo ayikho iyeza, ukuba nje ukugcinwa yezinyo lwawo, nto leyo ethintela ukusuka umonakalo ongaphezulu kude kube mzuzu xa umntwana ekhula phezulu. Oku kwanele ukuba ngokupheleleyo ugcine amazinyo abantwana.

Kufuneka kuqatshelwe ukuba fluoridation nesilivere - ezi nkqubo kakhulu ilula kwaye yalula kwaye akukho mfuneko ukwenza zomzimba. Xa bamazinyo, kwi-West ukuba ixhaphake kakhulu yaye ngokuthe ngcembe amazinyo aqhelekileyo kunye zasekhaya.

fluorination kunye nenkqubo silvering kufuneka wenziwe kunye rhoqo ethile, leyo ixhomekeke imeko kwamazinyo kwaye ziya makuxhaswe gqirha khona.
