Abstract
The longevity of restorative materials depends on the resistance to masticatory forces. The present study was undertaken to evaluate the microleakage properties of different restorative materials. A total of 30 specimen blocks were prepared with 10 samples of each type of restorative material, namely GIC Fuji IX, Filtek Z-350 Composite, and Cention-N. Class I cavities were prepared with dimensions 1.5 x 2 x 2 mm (l x b x h) of cavity size of orthodontically extracted premolars followed by restoration of each test material. We found thatCention-N has shown the least microleakage as compared to other groups. Mean microleakage was the least for Cention-N. It’s a newer restorative material having higher mechanical properties with lesser microleakage. Cention-N is a newer restorative material having promising properties. This material can be used as an alternative restorative material.
