A study carried out recently has revealed that chemicals found in certain dental fillings are causing children to behave badly. The study, which was carried out by the New England Research Institute, wanted children who had at least two cavities and examined their behaviour pre-dental treatment and after having work completed.
The findings showed a high number of children who had fillings fabricated from plastics-based bisphenol-A or BPA had distinctly more behavioural problems than children who had fewer of the fillings. The study also covered off children aged six to 10 years of age who had their cavities fixed with mercury-based filling, amalgam. Due to the levels of mercury this has been phased out but showed that his type of filling had no effect on the children’s conduct.
It had been exposed in previous research that people who had been exposed to BPA were hyperactive and showed signs of aggression. Composite fillings, including the BPA based kind, became the standard during the nineties as they were considered to look more natural and were thought to safer than those containing mercury.
