Kutheni iFluoride Toothpaste isetyenziswa kakhulu?
I-fluoride toothpaste ifumaneka kakhulu eMelika kuba ingqinwe ukuba iyathintela imingxunya kwaye iyaxhaswa kakhulu yimibutho ephambili yamazinyo kunye nezempilo yoluntu. Amagunya ezempilo, kuquka iZiko loLawulo lweZifo kunye nokuThintela (CDC), athi i-fluoride yehla kakhulu kumazinga okubola kwamazinyo kuzwelonke. Namhlanje, ngaphezulu kwe-95% ye-toothpaste ethengiswa eMelika ine-fluoride—ehlala isetyenziswa njenge-sodium fluoride okanye i-sodium monofluorophosphate malunga ne-1,000–1,100 ppm. Iingcali ziyavuma ukuba ukudibanisa amanzi ane-fluoride kunye ne-fluoride toothpaste kunika ukhuseleko oluphezulu ekuboleni xa kuthelekiswa nokusebenzisa nayiphi na indlela yokulinganisa yodwa. Ngenxa yoko, ukuxubha kabini ngemini nge-fluoride toothpaste eyamkelwe yi-ADA kuye kwaba yindlela eqhelekileyo phantse kuwo onke amakhaya aseMelika.
Imvelaphi Yembali YeFluoride Kwimpilo Yomlomo YaseMelika
Ukusetyenziswa kwe-fluoride kunyango lwamazinyo lwaseMelika kuqale ekuqaleni kwenkulungwane yama-20, xa uGqr. Frederick McKay wafumanisa "iColorado Brown Stain," kamva eyanxulunyaniswa ne-fluoride yendalo egqithisileyo emanzini. Ngo-1945, iGrand Rapids, eMichigan yaba sisixeko sokuqala ehlabathini ukugcwalisa umbane wamanzi kawonke-wonke nge-fluoride, nto leyo enika ubungqina obucacileyo bokuba i-fluoride iyanciphisa imingxunya. Ngeminyaka yoo-1970, abantu baseMelika abangaphezu kwezigidi ezili-100 bafumana amanzi ane-fluoride, kwaye uphando lwakhawuleza lwajika lwaya ekufakeni i-fluoride kwi-toothpaste.
Ngo-1956, iProcter & Gamble yazisa iCrest, i-toothpaste yokuqala ye-fluoride eyathengiswa kuzwelonke. I-Crest yafumana i-Seal of Acceptance ye-American Dental Association ngo-1960, nto leyo eyabangela ukuba nezinye iimpawu zilandele. Ngeminyaka yoo-1970, i-fluoride yayisele imiselwe njengesixhobo esiqhelekileyo sokulwa nemingxunya, kwaye phantse yonke i-toothpaste ephambili kwiishelufu zase-US yayine-fluoride.
Isicelo kunye noMgaqo
Ukwamkelwa kweFluoride Toothpaste kwiMarike yaseMelika
Emva kokuqaliswa ngempumelelo kweCrest, imakethi yamazinyo eMelika yatshintsha ngokukhawuleza. Ngeminyaka yoo-1980, phantse zonke iimpawu eziphambili zazinika ifomula ye-fluoride, kwaye ukwamkelwa kwabathengi kwanda kakhulu. Uphando lwemarike ngeminyaka yoo-1990 lubonise ukuba ngaphezulu kwe-90% yabantwana nabantu abadala baseMelika babesebenzisa i-fluoride toothpaste. Namhlanje, ii-aisles zeevenkile ezinkulu zilawulwa ziimveliso ezisekelwe kwi-fluoride, eziqhutywa ziingcebiso ezinamandla ezivela koogqirha bamazinyo kunye nemfuneko yokuba nayiphi na i-toothpaste ephethe i-ADA Seal kufuneka ibe ne-fluoride.
Isikhokelo soLawulo esiLawula iFluoride kwiToothpaste
E-United States, i-fluoride toothpaste ilawulwa njengeyeza elithengiswa ngaphandle kwe-counter (OTC) phantsi kwe-Food and Drug Administration's (FDA) Anticaries Monograph (21 CFR 355). I-FDA ivumela iikhompawundi ezithile ze-fluoride—ezifana ne-sodium fluoride, i-sodium monofluorophosphate, kunye ne-stannous fluoride—kwizinga elilawulwayo. Iifomyula ze-toothpaste eziqhelekileyo zinqunyelwe kwi-850–1,150 ppm fluoride (0.085%–0.115% fluoride ion). Udidi "lwe-high-fluoride" (ukuya kuthi ga kwi-1,500 ppm) luvunyelwe kuphela ngezilumkiso ezongezelelweyo zokhuseleko; nantoni na engaphezulu kwe-1,500 ppm ifuna ummiselo.
Iimfuneko zokubhala iilebheli nazo zingqongqo. Intlama yamazinyo kufuneka izichaze ngokucacileyo njenge "anticavity" okanye "fluoride" kwigama lemveliso, idwelise isithako se-fluoride esisebenzayo kunye nepesenti yaso, kwaye ibonise isilumkiso sokhuseleko lomntwana phantsi kwesihloko esithi "Iinkcukacha zeDrug": "Gcina kude nokufikelela kubantwana abangaphantsi kweminyaka emi-6 ubudala. Ukuba kuginywe ngengozi ngaphezulu kwento esetyenziselwa ukuxubha, fumana uncedo lwezonyango okanye uqhagamshelane neZiko loLawulo lweTyhefu ngokukhawuleza." Imiyalelo yokusebenzisa—njengokuxubha kabini ngemini kunye nokujonga abantwana abangaphantsi kweminyaka emi-6—nayo iyafuneka. Le mithetho iqinisekisa ukuba abathengi bafumana isikhokelo esicacileyo malunga nokusetyenziswa kwe-fluoride ngokukhuselekileyo nangokusebenzayo.
Ukusebenza kakuhle kunye nokhuseleko
Iingenelo zezeMpilo zoLuntu kunye nokusebenza kakuhle
Uphando lweminyaka emininzi lubonisa ukuba i-fluoride toothpaste iyanciphisa kakhulu ukubola kwamazinyo. Uphononongo olubalulekileyo oluvela kwiCochrane Collaboration lufumanise ukuba i-fluoride toothpaste (≥1,000 ppm) ithintela imingxunya ebantwaneni ngokufanelekileyo kunezinye iindlela ezingezizo i-fluoride. Ngokomndilili, ukuxubha kabini nge-fluoride toothpaste kunciphisa umngcipheko wokubola kwamazinyo nge-14–30%. Isenzo se-fluoride esisesikhundleni sinceda ekuvuseleleni i-enamel kwaye, xa idityaniswe namanzi ane-fluoride, inokunciphisa ukubola ukuya kuthi ga kwi-25% kwinqanaba labemi. Ezi ziphumo ziye zabonakala kumazwe kwihlabathi liphela, ziqinisekisa i-fluoride toothpaste njengenye yezona ndlela zokungenelela ezingabizi kakhulu kwimpilo yomlomo.
Iingxaki zoKhuseleko kunye neengxabano
Eyona ngxaki iphambili yokhuseleko nge-fluoride toothpaste kukuvezwa kakhulu kwamazinyo kubantwana abancinci, okunokukhokelela kwi-dental fluorosis (amazinyo amhlophe okanye amdaka). Idatha yase-US ukusuka ngo-1999-2004 ibonisa ukuba malunga ne-40% yolutsha lubonisa inqanaba elithile le-fluorosis, nangona uninzi lweemeko zincinci kwaye zintle kuphela. Ukunciphisa umngcipheko, iingcali zezempilo zicebisa ukusebenzisa inani "lerayisi-grain" le-toothpaste kubantwana abangaphantsi kweminyaka emi-3 kunye nenani "leepizi" kubantwana abaneminyaka emi-3-6, kunye nolawulo lomntu omdala ukuthintela ukuginya.
Ubuthi be-fluoride obubukhali obuvela kwi-toothpaste bunqabile kakhulu, bufuna ukutyiwa ngobuninzi. Imibutho ephambili yezempilo—kuquka i-CDC, i-ADA, kunye ne-American Academy of Pediatrics—iqinisekisa ukuba i-toothpaste ene-fluoride ikhuselekile xa isetyenziswa njengoko kuyalelwe. Nangona izifundo ezimbalwa ziphakamise imibuzo malunga nempembelelo ye-fluoride ekuphuhlisweni kwemithambo-luvo kumanqanaba aphezulu okuchaphazeleka, oku kuchaphazeleka kungaphezulu kakhulu koko umntwana angakufumana kwi-toothpaste okanye emanzini ane-fluoride.
Kufuphi
Xa abazali belandela imiyalelo yokusebenzisa ebhalwe ngamagama, umngcipheko wokwenzakala emzimbeni awunakulinganiswa.
Izenzo Zakutshanje Zezopolitiko Nezomthetho eMelika
Ngowama-2024 nangowama-2025, amazwe aliqela atshintshe indlela yokuthintela ukusetyenziswa kwamanzi amdaka kuluntu—isenzo esinefuthe elingathanga ngqo ekuxhomekekeni koluntu kwi-toothpaste ene-fluoride. Umzekelo, i-Utah neFlorida zapasisa imithetho ethintela ukusetyenziswa kwamanzi amdaka, nto leyo eyabangela ukuchaswa okukhulu ziingcali zamazinyo nezezempilo zoluntu ezilumkisa ukuba ukususa i-fluoride kusenokwenzeka ukuba kuya kwandisa imingxunya, ingakumbi phakathi kwabantwana. Ijaji yelizwe ikwayalele i-EPA ukuba iphinde ihlole imigangatho ye-fluoride emanzini okusela, icaphula izifundo malunga nemiphumo enokubakho yophuhliso lwe-neurode. Ngelixa esi sigwebo sibhenelwa, i-CDC kunye ne-ADA baqinisekisile ukuba ukusetyenziswa kwamanzi amdaka kuseyenye yezona mpumelelo ziphambili kwimpilo yoluntu kwimbali yase-US.
Ukuhlolwa ngokusemthethweni kwentengiso yamazinyo nakho kuye kwanda. Ekuqaleni kuka-2025, kwafakwa amatyala etyala lamaqela ngokuchasene nabavelisi abakhulu bamazinyo, betyhola ukuthengisa "okukhohlisayo" ebantwaneni—amabango okuba amazinyo amazinyo anencasa, anophawu lweekhathuni akhuthaza ukuginya nokulahlekisa abazali. Igqwetha Jikelele laseTexas liqalise uphando malunga nokuba ukupakisha kunye neentengiso kuyaphula na imigaqo ye-FDA malunga nokusetyenziswa kwe-fluoride. I-ADA iphendule ngokuphinda ithi amazinyo amdaka akhanyayo, asetyenziswa phantsi kweliso, akhuselekile kwaye ayasebenza.
Impendulo yoShishino kunye neMikhwa eBalaseleyo
Abavelisi abakhulu bamazinyo—abafana neColgate-Palmolive kunye neProcter & Gamble—bagxininisa ukunamathela ngokungqongqo kwiimfuno ze-FDA monograph, uvavanyo oluqinileyo lwezithako, kunye nokubhala iilebhile ezicacileyo. Babonisa ngokucacileyo i-ADA Seal of Acceptance kwiphakheji ukuqinisekisa abathengi ngokuqinisekiswa komntu wesithathu. Abavelisi bakwabandakanya iikepusi ezimelana nabantwana kunye nemiyalelo yedosi ukunciphisa iingozi zokuginya. Emva kwemingeni yezomthetho yakutshanje, amaqela oshishino aqinise isikhokelo sokusetyenziswa ngokukhuselekileyo: abantu abadala kufuneka bajonge abantwana abangaphantsi kweminyaka emi-6, kwaye kufuneka kulandelwe ngokungqongqo ubungakanani bamazinyo (irayisi-iinkozo okanye ubungakanani beepizi).
Ukongeza kwiimveliso eziqhelekileyo, ezinye iinkampani "zendalo" okanye ezizodwa zibonelela ngee-toothpastes ezingena-fluoride ukuhlangabezana neemfuno zabathengi. Nangona kunjalo, ezi mveliso azinazo izityholo zokungaphila kwaye zisenokungabi nanqanaba lifanayo lokuthintela ukubola. Ngokubanzi, imeko yeli shishini icacile: i-toothpastes ene-fluoride ihlala iyeyona ndlela isebenzayo yokukhusela imingxunya, kwaye abavelisi baya kuqhubeka nokuphucula ukulebhelisha, ukupakisha, kunye nemizamo yemfundo ukuqinisekisa ukusetyenziswa okukhuselekileyo nokuqondayo.
Iimbono zeHlabathi jikelele malunga noLawulo lweFluoride
Kwihlabathi liphela, kukho ukuvumelana ngokubanzi malunga neenzuzo ze-fluoride toothpaste, nangona iinkcukacha zomthetho zahlukile. Kwi-European Union, ii-toothpaste zihlelwa njengezinto zokuthambisa kwaye zifikelela kwi-1,500 ppm fluoride. Iifomyula zabantwana zihlala ziqulathe i-500–600 ppm ukunciphisa umngcipheko we-fluorosis. Ekubeni imalunga ne-3% kuphela yabantu baseYurophu abafumana amanzi ane-fluoride, i-fluoride toothpaste idlala indima ebalulekileyo ekuthinteleni ukubola. Imithetho yaseKhanada ifana neyaseMelika, iphatha i-toothpaste yokulwa nesifo samathambo njengeyeza elithengiswa ngaphandle kwemvume kwaye ixhasa isikhokelo somthamo ofanayo kubantwana. I-Australia ivumela ukuya kuthi ga kwi-1,450 ppm fluoride kwi-toothpaste kwaye ixhasa kakhulu i-fluoride yamanzi kuluntu. Imibutho yamazwe ngamazwe, kuquka ne-World Health Organisation, icebisa ukusebenzisa i-toothpaste ene-1,000–1,500 ppm fluoride kwiindawo ezingenayo i-fluoride emanzini. Ngamafutshane, ngelixa ukuhlelwa nokusetyenziswa kwahluka kancinci, i-fluoride toothpaste ibonwa njengebalulekileyo kwimpilo yomlomo.
Isiphelo kunye nobizo lokwenza isenzo
I-fluoride toothpaste isalokhu isisiseko sezicwangciso zempilo yomlomo eMelika. Iingcali zempilo eziphambili—kuquka i-CDC, i-ADA, kunye ne-American Academy of Pediatrics—ziyaqhubeka nokucebisa ukuxubha kabini nge-fluoride toothpaste kwaye zigxininisa ukubekwa esweni okufanelekileyo kunye nomthamo wabantwana abancinci. Nangona kukho iimpikiswano ezithile, amashumi eminyaka obungqina besayensi aqinisekisa ukuba i-fluoride toothpaste ikhuselekile kwaye isebenza kakhulu ekuthinteleni imingxunya. Njengoko imigaqo-nkqubo yokukhupha amanzi kunye ne-fluoride itshintsha, i-toothpaste iya kuhlala iyeyona ndlela ifikelelekayo kubantu baseMelika yokukhusela amazinyo abo.
I-IVISMILEikhuthaza bonke abathengi ukuba bakhethe i-toothpaste ene-fluoride evunyiweyo yi-ADA kwaye balandele imiyalelo ebhalwe apha: sebenzisa isixa serayisi-inkozo kubantwana abangaphantsi kweminyaka emi-3, isixa seepizi esilingana ne-3-6 ubudala, kwaye ujonge ukuxubha. Ngokudibanisa ukusetyenziswa kwe-toothpaste ngokufanelekileyo nokutya okunesondlo kunye nokuhlolwa rhoqo kwamazinyo, iintsapho zinokuphucula impilo yomlomo kwaye zonwabele uncumo oluqaqambileyo nolunempilo kwiminyaka ezayo.
