title: [The testing of the toxicity of the plastics used in orthodontics].
abstract: Eighteen bracket adhesives and one to three differently coloured samples of the plastic materials Orthocryl and Wil-o-dont used for removable appliances were tested for toxicity in vitro by cell culture using both L-929 mouse fibroblasts and human keratinocytes. The results differed from product to product. Some adhesives were moderately and some slightly toxic, while others were non-toxic. After 30 days of washing in PBS, none of the adhesives showed any toxicity. Orthocryl was not toxic regardless of colour, while the possible toxicity of Wil-o-dont could be a problem.
