This video shows how they fill a cavity with composite. The second syringe he use contain an adhesive. ( the glueueueue ) Several dentists told me that dentists never apply this material with a syringe but with a microbrush. The video tells me the opposite. These materials are volatile, so a syringe can easely clog. If they put to much pressure on a clogged syringe it can easely lead to accidents.( as in my case) Accidents lead to severe toxicity for a very very long time! They should take his license for his inaccurate work. I hope the little girl is oke....!!
