The optical property is distinct in youthful teeth, where reflected light from the crown gives a blue appearance the incisal third, but in transmitted light the crown has an orange appearance in the incisal third. Available in opal effect 1 and opal effect 2 shades. Mix opal effect powders with Elegant Dent modelling liquid to achieve the correct consistency and obtain optimal results.
