Effect of different post-cure heat-treatment methods on the dimensional stability of a visible-light cured-composite inlays

A total number of 50 rectangular specimens, made of hybrid visible light cured composite were used in the present study. The specimens were divided into 5 groups (10 specimens each). Each group was treated with one of the post-cure heat-treatment methods. It was found that, the specimens exposed to...

Summary:A total number of 50 rectangular specimens, made of hybrid visible light cured composite were used in the present study. The specimens were divided into 5 groups (10 specimens each). Each group was treated with one of the post-cure heat-treatment methods. It was found that, the specimens exposed to the normal post-cure heat-treatment method demonstrated the minimum dimensional change values (0.62%, 0.166%, 1.4% and 2.23%) for length, width, and volume respectively. On the other hand, the specimens exposed to the (delay-heat) water ageing method displayed the maximum values (2.9%, 0.56%, 9.2%, and 9.98%) for the length, width, height, and volume respectively.
