Bisfenola A saturošo zobārstniecības kompozītu genotoksicitāte

2019

Daži zobārstniecībā izmantojamie sveķu kompozīti satur monomērus ar BPA kā bāzes elementu, kas izraisa dzīvo šūnu genotoksicitāti un spēj izraisīt dzīvo šūnu nāvi. Šie monomēri spēj noārdīties cilvēka siekalās esošo esterāžu iedarbībā, tādējādi izdalot toksiskos noārdīšanās produktus mutes dobumā. Izdalītie monomēri pat var iekļūt asinsritē, izejot cauri zoba struktūrām uz pulpu. Šī pētījuma mērķis bija izpētīt zobārstniecības kompozīta materiālu ietekmi uz cilvēka asins šūnām, tieši uz limfocītiem, un novērtēt šūnu DNS bojājumu līmeni. Lai izpētītu šo jautājumu, 4 dažādi komerciāli pieejamie zobārstniecības kompozīta materiālu fragmenti tika izmērcēti izolētās cilvēka perifēro asiņu mononu…
