CHAMPIONSGATE, FL, Lub Rau Hli 14, 2022/PRNewswire/ — Lub Tsev Kawm Ntawv Qib Siab International ntawm Oral Medicine thiab Toxicology (IAOMT) yog tsa kev paub txog kev tshawb fawb txuas cov ntsiab lus tseem ceeb ntawm cov mercury excretion mus rau qhov muaj cov hniav amalgam txhaws hauv lub qhov ncauj. Cov no hu ua "silver" fillings kuj hu ua amalgams yog tiag tiag 50% lossis ntau dua mercury thiab tau siv dav hauv Tebchaws Meskas, hauv txhua ceg ntawm tub rog, kev pov hwm tus nqi qis thiab cov menyuam yaus thiab cov neeg laus tsis zoo.
Nyob rau hauv lub kev kawm tam sim no, cov kws tshawb fawb David thiab Mark Geier tau tshuaj xyuas cov urinary mercury excretion ntawm ntau dua 150 lab tus neeg Asmeskas siv CDC's 2015-2018 National Health and Nutrition Examination survey (NHANES). Geiers ' pom muaj kev sib raug zoo heev ntawm tus naj npawb ntawm kev kho hniav amalgam sau qhov chaw hauv lub qhov ncauj thiab cov nyiaj mercury tawm.

Ntawm 91 lab (57.8%) cov neeg laus uas muaj 1 lossis ntau qhov chaw ntawm cov mercury txhaws, cov mercury hauv lawv cov zis sib cuam tshuam nrog cov naj npawb ntawm cov chaw ntawm amalgam. Cov Geiers tau sau tias, "Txhua hnub Hg vapor koob tshuaj los ntawm amalgams tau dhau ntawm kev tiv thaiv feem ntau California Lub Chaw Tiv Thaiv Ib puag ncig (EPA) txwv kev nyab xeeb rau kwv yees li 86 lab (54.3%) cov neeg laus". Teb Chaws Asmeskas EPA qhov kev pheej hmoo tsawg kawg nkaus (MRL) rau mercury yog qhov siab dua li CalEPA's MRL vim qhov tseeb tias los ntawm txoj cai CalEPA's MRL yuav tsum tiv thaiv qhov tsis zoo, tsis yog qhov nruab nrab. Txawm li cas los xij, 16 lab tus neeg laus raug cuam tshuam rau qib mercury ntau dua US EPA's MRL.
Cov ntaub ntawv zoo sib xws txog kev raug mob ntau dhau tau nthuav tawm los ntawm IAOMT ntawm FDA cov kws tshaj lij lub rooj sib hais txog kev nyab xeeb ntawm amalgam hauv xyoo 2010 thiab ib tus kws kho hniav ntawm lub vaj huam sib luag tau nug cov kws tshaj lij los ntawm Lub Chaw Haujlwm Saib Xyuas Tshuaj Tiv Thaiv thiab Tshuaj Tiv Thaiv Kab Mob (ATSDR) ntau npaum li cas tshaj MRL koj tuaj yeem ua tau. mus thiab tseem muaj kev nyab xeeb. Dr. Richard Kennedy ntawm ATSDR piav qhia tias ib tus tsis tuaj yeem tshaj MRL thiab tseem cia siab tias yuav muaj kev nyab xeeb.

"Cov tshuaj mercury vapors tsis tu ncua tawm-gassed los ntawm kev kho hniav amalgam sau nrog kev txhawb nqa xws li zom," piav qhia David Kennedy, DDS, yav dhau los IAOMT Thawj Tswj Hwm. "Nrog Geiers cov kev tshawb fawb tshiab koom nrog ntau pua ntawm lwm cov kev tshawb fawb, nws muaj ntau qhov tseeb tias mercury los ntawm amalgams ua rau muaj kev phom sij rau txhua tus, suav nrog cov me nyuam mos, cov neeg mob, kws kho hniav, thiab cov neeg ua haujlwm kho hniav."
Geiers txoj kev tshawb fawb yog ib feem nyiaj los ntawm IAOMT, ib lub koom haum tsis muaj txiaj ntsig uas ntsuas biocompatibility ntawm cov khoom siv kho hniav, suav nrog mercury filling txaus ntshai.
