Bisphenol A fillings may have some unintended results.
A new study indicates that BPA fillings may be linked to behavioral problems in children. The research showed that children who had some type of dental fillings made from BPA had a higher chance to encounter some type of behavioral or emotional problem.
The research did not take into account the level of BPA in the fillings. There was no research done on some of the other chemicals that may have been present in the fillings, either.
The study was done, according to lead researcher Nancy Maserejian of the New England Research Institutes in Waretown, Mass., because the leaching process of chemicals from fillings is a hot-button issue in dentistry.
BPA fillings are becoming more prevalent because of their color, which blends in with teeth. BPA, however, is also a substance utilized in the manufacturing of packaging materials and tinned items.
The researchers poured through data of 534 children ages 6 through 10 who had some type of amalgam or composite filling. BPA was utilized in one of the two newer kinds of fillings.
Five years after the receiving the filling, the parents answered questions about their child’s behavior and attitude, in addition to school and any feelings of anxiety/depression. The researchers concluded that children with BPA fillings had a higher point score on average (signifying behavioral issues).
The research also concluded that children with fillings on chewing surfaces of their teeth also had a higher point score. The possible leaching of chemicals in this case may come from the constant chewing and grinding of the teeth.
