IAOMT Oral Comments dzeNTP BSC

Mhoroi, ndiri Dr. Jack Kall, chiremba wemazino ari kudzidzira kwemakore makumi mana nematanhatu. Ini ndiri Sachigaro Mukuru weBhodi reVatungamiriri veInternational Academy yeOral Medicine uye Toxicology, kana IAOMT. Isu tiri sangano risingabatsiri rakavambwa muna 46.

Nhengo dzedu zana nemazana mashanu ndivanachiremba vemazino, varapi nevatsvaguri vanoferefeta nekutaura zvakachengeteka, marapirwo akavakirwa pasainzi kusimudzira hutano hwemuviri wese. Dingindira redu rinoti “Ndiratidze Sainzi”.

Yakawanda yekutarisisa kweAcademy yedu yanga iri pane toxicology yezvinhu zvinoshandiswa mukurapa mazino. Isu tiri sangano guru rakazvipira kune izvi. Isu takanyanya kutarisa pazvinhu zvitatu zvinowanzo shandiswa zvine chepfu mukurapa mazino:

1. mercury, neurotoxin, inoshandiswa mumalgam kuzadza
2. bisphenol A, endocrine disrupter, inoshandiswa muzvisimbiso uye kuzadza kwakaumbwa
3. fluoride inoshandiswa mu rinses, mazino, varnishes, simende uye kuzadza zvinhu

Zvose izvi zvinoiswa mumuromo. Pamusoro pezvo, fluoride inoshandiswa mune nzira dzekupinza zvakananga nenzira yemvura yekunwa ine fluoridated, fluoridated munyu, uye fluoride supplements.

Kweanopfuura makore makumi matatu sangano redu rave richitsigira nekupa mari kutsvagisa nezvehupfu hwefluoride. Isu tanga tichinyanya kufarira uye nekunetsekana zvakanyanya nezve zvidzidzo zvakangoburwa zvakaburitswa maererano neurotoxicity yefluoride uye saka tinotsigira iyo NTP's hurongwa hwekuongorora.

Isu takaodzwa mwoyo kuti fluoridation-inosimudzira zvido zvemazino mukati mehurumende yemubatanidzwa uye kunze kwayo, vanga vachiedza kufurira zvakawanikwa neNTP, kwete zvichibva pasainzi, asi mukuyedza kudzivirira mutemo wavo wekusimudzira mvura fluoridation.

Ndezvipi zvakakosha zvakawanikwa neNTP?

1. Ihwo humbowo hwechirwere chevanhu hunotsigira mhedziso ye "zvivimbo zvine mwero" kuti fluoride inovandudza neurotoxin. (BSC WG mushumo peji 342)
2. Kuti hapana chikumbaridzo chakachengeteka chakawanikwa chekuita kwefluoride paIQ. ( BSC WG report mapeji 87, 326, 327, 632, 703, 704)
3. Iko kufumurwa kwefluoride kunowanikwa nevakadzi vane nhumbu nevana muUS nhasi kuri mukati mechikamu umo zvidzidzo zvevanhu zvakawana yakaderedzwa IQ. (BSC WG shumo mapeji 25, 26)

Chirevo chinopa ruzivo rwakadzama pamusoro pezvidzidzo zvevanhu zvinopfuura 150 zvakaonekwa sezvine basa.

Chirevo chakashandisa nzira dzakasimba, dzakagara dzatangwa kuyera kunaka kwezvidzidzo zvega.

IAOMT inobvumirana nemhedziso dzeNTP.

Isu tinotenda kuti monograph yaifanira kunge yakaburitswa pazuva rayakada kuburitswa paruzhinji musi waChivabvu 18, 2022. Ongororo yakaitwa neNTP mushure mekuvharwa nekupatsanurwa kwefluoridation mukati meHHS, uye ongororo dzakataurwa neboka rinoshanda reBSC hazvizochinji. zvakawanikwa zvakakosha. Chero kumwe kunonoka kuzivisa mushumo wekupedzisira hakuna chikonzero.

IAOMT inotarisira kuti BSC ichatsigira kuedza kunoshamisa kwakaitwa nenyanzvi dzesainzi dzeNTP mukuongorora kwakarongeka. Tinobvumirana nevekunze vezera-vaongorori vakapa izvi zvirevo:

"zvawaita ndezvechizvino-zvino"

"Ongororo yacho pachayo yakanaka, uye wakanyatsogadzirisa mhinduro"

"Kuita zvakanaka!"

“Zvakawanikwa… zvakadudzirwa zvine mufungo”

Kubva pakunyatsoongorora uchapupu hwekubatana pakati pefluoride uye mazino emazino (kuora kwezino), IAOMT yakagumisa kushanda kwakanyanyisa kwehutano hwemazuva ano. Nyika dzine fluoridation nedzisina dzakasangana nekuderera kunoshamisa kwekuora kwemazino mumakore makumi mashanu apfuura, sezvakaratidzwa mugirafu rino zvichienderana nedata reWHO:

Muyedzo wenguva pfupi yapfuura wenharaunda yakakura yefluoridation, wakaitwa muEngland, wakangowana musiyano we 0.2 cavities pamwana mumazino emwana. Izvo hazvina kuwana zviverengero zvakakosha zvinobatsira zvachose mumazino echigarire. Chidzidzo ichi chakapihwa nePublic Health England, inotungamira kukurudzira fluoridation muEngland. Zvakadaro vanyori vechidzidzo ichi vakatogumisa kuti mabhenefiti "idiki kwazvo pane tsvakiridzo yakambotaurwa" uye kuti fluoridation haina kuderedza kusaenzana kwehutano hwemazino pakati pevarombo uye vana vakapfuma.

Kunyangwe US ​​CDC inobvuma kuti hapana humbowo hwekuti prenatal fluoride muna amai vane nhumbu kana mucheche mazino asati abuda inopa chero rubatsiro rwemazino. Idzi ndidzo nguva dzekuratidzwa uko humbowo hwekuvandudza neurotoxicity hwakasimba.

Nheyo yekona yegwaro rehutano hweveruzhinji rinozivikanwa seiyo precautionary musimboti rinofanira kutariswa zvakare. Chinonyanya kukosha chemutemo uyu chakavakirwa pamhiko yezvechiremba yemazana emakore yekuti "kutanga, usakuvadza." Asi, kushandiswa kwemazuva ano kwenheyo yokuzvidzivirira kunotsigirwa chaizvoizvo nechibvumirano chenyika dzakawanda.

Muna Ndira 1998, pamusangano wepasi rose waisanganisira vesainzi, magweta, vanogadzira mitemo, uye vezvezvakatipoteredza kubva kuUS, Canada neEurope, chirevo chepamutemo chakasainwa chikazozivikanwa se "Wingsspread Statement on the Precautionary Principle."530 Mariri, the zano rinotevera rinopiwa: “Apo chiito chinomutsa tyisidziro dzekuvadziko kuutano hwomunhu kana kuti mhoteredzo, matanho okuzvidzivirira anofanira kutorwa kunyange kana humwe hukama hwechisakiso nomugumisiro husina kusimbiswa zvizere nesayenzi. Muchirevo chechinyorwa chino mutsigiri wechiito, kwete veruzhinji, anofanira kutakura mutoro wehumbowo. "

Hazvishamisi kuti kudiwa kwekushandiswa kwakakodzera kweiyo nzira yekudzivirira kwave kwakabatana nekushandiswa kwefluoride. Vanyori vechinyorwa cha2006 chakanzi “Chii Chinorehwa Nemitemo Yekungwarira paKurapa Mazino Anoenderana Neuchapupu? vakakurudzira kudiwa kwekuzvidavirira kwekuwedzera kuratidzwa kubva kune ese fluoride masosi uye kusiyana kwehuwandu hwevanhu, ukuwo ichiti vatengi vanogona kusvika "yakanyanya" mazinga efluoridation vasina kumbonwa mvura ine fluoridated. Pamusoro pezvo, vaongorori veongororo yakabudiswa muna 2014 vakataura nezve chisungo chekuti mutemo wekuchengetedza ushandiswe pakushandiswa kwefluoride, uye vakatora pfungwa iyi imwe nhanho mberi pavakakurudzira kuti kunzwisisa kwedu kwemazuva ano kwemeno caries "inoderedza chero basa rakakura remangwana fluoride mukudzivirira caries."

Ini ndinovhara nenzvimbo yeIAOMT pafluoride:

"Muchidimbu, tichifunga nezvehuwandu hwakasimudzwa hwemanyuko efluoride uye kuwedzera kwehuwandu hwehuwandu hwefluoride muhuwandu hweAmerica, iyo yakakwira zvakanyanya kubva pakatanga mvura fluoridation muma1940, chave chinhu chinodiwa kudzikisa uye kushanda mukubvisa angadzivirirwa efluoride. kufumurwa, kusanganisira mvura fluoridation, fluoride ine mazino zvinhu, uye zvimwe zvigadzirwa zvine fluoridated.
