IAOMT's Response to the National Toxicology Program's (NTP) Board of Scientific Counselors (BSC)

IAOMT Oral Comments for NTP BSC

Nyob zoo, kuv yog Dr. Jack Kall, kws kho hniav muaj 46 xyoo. Kuv yog Thawj Tswj Hwm ntawm Pawg Thawj Coj ntawm International Academy of Oral Medicine thiab Toxicology, lossis IAOMT. Peb yog ib lub koom haum non-profit uas tau tsim nyob rau xyoo 1984.

Peb 1500 cov tswv cuab yog kws kho hniav, kws kho mob thiab cov kws tshawb fawb uas tshawb xyuas thiab sib txuas lus muaj kev nyab xeeb, kev kho mob raws li kev tshawb fawb los txhawb kev noj qab haus huv ntawm lub cev. Peb lub ntsiab lus yog "Show Me The Science".

Ntau ntawm peb lub Academy qhov kev tsom mus rau toxicology ntawm cov ntaub ntawv siv hauv kev kho hniav. Peb yog lub koom haum loj tshaj plaws rau qhov no. Peb tau tsom tshwj xeeb rau peb cov khoom siv tshuaj lom neeg hauv kev kho hniav:

1. mercury, ib tug neurotoxin, siv nyob rau hauv amalgam txhaws
2. bisphenol A, ib qho kev cuam tshuam endocrine, siv nyob rau hauv sealants thiab composite fillings
3. fluoride siv nyob rau hauv yaug, tshuaj txhuam hniav, varnishes, cements thiab filling cov ntaub ntawv

Tag nrho cov no yog muab tso ncaj qha rau hauv lub qhov ncauj. Tsis tas li ntawd, fluoride yog siv nyob rau hauv cov kev hloov ntawm kev noj cov tshuaj fluoridated, fluoridated ntsev, thiab tshuaj fluoride.

Rau ntau tshaj 30 xyoo peb lub koom haum tau txhawb nqa thiab pab nyiaj rau kev tshawb fawb txog tshuaj fluoride toxicity. Peb tau txaus siab tshwj xeeb thiab muaj kev txhawj xeeb heev txog kev tshawb fawb tsis ntev los no hais txog cov neurotoxicity ntawm fluoride thiab yog li txhawb NTP qhov kev tshuaj xyuas zoo.

Peb poob siab tias fluoridation-txhim kho hniav kev nyiam nyob rau hauv tsoom fwv teb chaws thiab sab nraum nws, tau sim los cuam tshuam rau NTP qhov kev tshawb pom, tsis yog raws li kev tshawb fawb, tab sis nyob rau hauv ib qho kev rau siab tiv thaiv lawv txoj cai ntawm kev txhawb dej fluoridation.

NTP qhov kev tshawb pom tseem ceeb yog dab tsi?

1. Cov ntaub ntawv pov thawj ntawm tib neeg kev sib kis tau txhawb nqa qhov xaus ntawm "kev ntseeg siab nruab nrab" tias fluoride yog ib qho kev loj hlob ntawm neurotoxin. (BSC WG report page 342)
2. Tias tsis muaj qhov chaw nyab xeeb raug pom zoo rau cov tshuaj fluoride cuam tshuam rau IQ. (BSC WG report page 87, 326, 327, 632, 703, 704)
3. Cov tshuaj fluoride uas tau ntsib los ntawm cov poj niam cev xeeb tub thiab cov menyuam yaus hauv Asmeskas niaj hnub no yog nyob rau hauv ntau qhov kev tshawb fawb tib neeg tau pom tias txo IQ. (BSC WG report page 25, 26)

Daim ntawv tshaj tawm muab cov ncauj lus nthuav dav ntawm ntau dua 150 tib neeg kev tshawb fawb pom tias muaj feem cuam tshuam.

Daim ntawv tshaj tawm tau siv cov txheej txheem nruj, tsim ua ntej los ntsuas qhov zoo ntawm cov kev tshawb fawb ntawm tus kheej.

IAOMT pom zoo nrog NTP cov lus xaus.

Peb ntseeg hais tias cov monograph yuav tsum tau luam tawm nyob rau hauv nws lub hom phiaj tshaj tawm hnub tim 18 lub Tsib Hlis 2022. Cov kev hloov kho NTP tau ua tom qab nws raug thaiv los ntawm fluoridation-txhim khu kev faib hauv HHS, thiab cov kev hloov kho uas tau hais los ntawm BSC pawg neeg ua haujlwm yuav tsis hloov pauv. kev tshawb pom tseem ceeb. Ib qho kev ncua ntxiv hauv kev tshaj tawm tsab ntawv ceeb toom zaum kawg yog tsis ncaj ncees.

IAOMT vam tias BSC yuav txhawb nqa qhov kev siv zog zoo kawg uas NTP cov kws paub txog kev tshawb fawb tau muab tso rau hauv qhov kev tshuaj xyuas no. Peb pom zoo nrog cov neeg saib xyuas sab nraud uas tau hais cov lus no:

"qhov koj tau ua yog lub xeev-ntawm-tus-kos duab"

"Qhov kev tshuaj ntsuam nws tus kheej yog qhov zoo heev, thiab koj tau hais meej cov lus"

“Ua tau zoo!”

“Nrhiav… tau txhais objectively”

Los ntawm kev ua tib zoo tshuaj xyuas cov pov thawj ntawm kev sib koom ua ke ntawm cov tshuaj fluoride thiab cov kab mob hniav (cov hniav lwj), IAOMT tau xaus lus tias qhov kev ua tau zoo yog overstated rau niaj hnub no qhov ncauj noj qab haus huv teeb meem. Cov teb chaws uas muaj cov tshuaj fluoridation thiab cov uas tsis muaj ob qho tib si tau ntsib tib qhov kev poob qis hauv cov hniav lwj dhau 50 xyoo dhau los, raws li qhia hauv daim duab no raws li WHO cov ntaub ntawv:

Qhov kev sim loj tshaj plaws hauv zej zog fluoridation tsis ntev los no, ua tiav hauv tebchaws Askiv, pom tsuas yog qhov sib txawv ntawm 0.2 kab noj hniav rau ib tus menyuam hauv cov hniav me nyuam. Nws pom tsis muaj qhov txiaj ntsig tseem ceeb ntawm txhua qhov ntawm cov hniav mus tas li. Txoj kev tshawb no tau raug txib los ntawm Public Health England, tus thawj coj txhawb nqa ntawm fluoridation hauv tebchaws Askiv. Txawm li cas los xij, txoj kev tshawb fawb cov kws sau ntawv txawm xaus lus tias cov txiaj ntsig "muaj tsawg dua li qhov kev tshawb fawb yav dhau los tau hais tseg" thiab tias fluoridation tsis txo qis kev noj qab haus huv ntawm cov hniav ntawm cov menyuam yaus thiab cov neeg muaj nyiaj.

Txawm tias US CDC lees paub tias tsis muaj pov thawj tias muaj cov tshuaj fluoride ua ntej cev xeeb tub hauv niam cev xeeb tub lossis hauv cov menyuam mos ua ntej cov hniav tau tawg muab cov txiaj ntsig kho hniav. Cov no yog lub sijhawm raug pom tseeb uas cov pov thawj rau kev loj hlob neurotoxicity muaj zog tshaj.

Lub hauv paus ntawm txoj cai tswjfwm kev noj qab haus huv rau pej xeem hu ua txoj cai ceev faj yuav tsum tau txiav txim siab ib yam. Lub hauv paus ntsiab lus ntawm txoj cai no yog tsim los ntawm kev cog lus kho mob ntau pua xyoo kom "ua ntej, tsis txhob ua phem." Txawm li cas los xij, kev siv niaj hnub no ntawm lub hauv paus ntsiab lus kev tiv thaiv tau txais kev txhawb nqa los ntawm kev pom zoo thoob ntiaj teb.

Thaum Lub Ib Hlis Ntuj xyoo 1998, ntawm lub rooj sib tham thoob ntiaj teb uas muaj cov kws tshawb fawb, kws lij choj, cov tsim cai lij choj, thiab cov kws saib xyuas ib puag ncig los ntawm Asmeskas, Canada thiab Europe, cov lus tshaj tawm tau raug kos npe thiab dhau los ua lub npe hu ua "Wingspread Statement on the Precautionary Principple." 530 Nyob rau hauv nws, lub cov lus qhia nram qab no tau muab: “Thaum ib qho kev ua ub no ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv lossis ib puag ncig, yuav tsum tau ceev faj txog kev tiv thaiv kev sib raug zoo txawm tias qee qhov kev sib raug zoo thiab kev sib raug zoo tsis tau tsim los ntawm kev tshawb fawb. Nyob rau hauv cov ntsiab lus no tus neeg txhawb nqa ntawm ib qho kev ua, es tsis yog pej xeem, yuav tsum ris lub nra ntawm pov thawj. "

Tsis yog qhov xav tsis thoob, qhov kev xav tau ntawm cov ntawv thov tsim nyog ntawm txoj cai ceev faj tau cuam tshuam nrog kev siv tshuaj fluoride. Cov kws sau ntawv ntawm xyoo 2006 tsab xov xwm hu ua "Lub Ntsiab Cai Tswjfwm Ntiag Tug txhais li cas rau Cov Ntawv Pov Thawj-Raws Kev Kho Hniav?" qhia txog qhov yuav tsum tau ua kom suav nrog kev nthuav tawm los ntawm txhua qhov chaw fluoride thiab cov pej xeem sib txawv, thaum tseem hais tias cov neeg siv khoom tuaj yeem ncav cuag qib "zoo" fluoridation yam tsis tau haus dej fluoridated. Tsis tas li ntawd, cov kws tshawb fawb ntawm kev tshuaj xyuas luam tawm xyoo 2014 tau hais txog lub luag haujlwm rau txoj cai tiv thaiv kev siv tshuaj fluoride, thiab lawv tau siv lub tswv yim no ib kauj ruam ntxiv thaum lawv hais tias peb niaj hnub kev nkag siab ntawm cov hniav caries "txo qis dua lub luag haujlwm tseem ceeb yav tom ntej rau fluoride hauv kev tiv thaiv kab mob. "

Kuv kaw nrog IAOMT txoj haujlwm ntawm fluoride:

"Raws li cov ntsiab lus, muab cov tshuaj fluoride ntau ntxiv thiab qhov nce ntxiv ntawm cov tshuaj fluoride hauv Asmeskas cov pej xeem, uas tau nce ntau heev txij li cov dej fluoridation pib hauv xyoo 1940, nws tau dhau los ua qhov tsim nyog los txo thiab ua haujlwm kom tshem tawm cov fluoride uas tsis tuaj yeem zam tau. raug, suav nrog dej fluoridation, fluoride uas muaj cov ntaub ntawv kho hniav, thiab lwm yam khoom fluoridated.
