Despite legal regulations limiting emissions of persistent organic pollutants (POPs), including dioxins, to the environment, they still constitute a significant component of environmental contamination. They are released in large amounts during various processes of combustion in industry, the management of refuse materials and also as a result of situations that are partially beyond our control, like fires, explosions and damage in chemical industries. Observations originating from various studies prove that exposure to dioxins results in multiple toxic effects on humans and experimental animals. Among the various disorders caused by dioxins are abnormalities in dentition. The effects of dioxin may last long after exposure.
