Background: The present study was conducted to compare the microleakage of three different direct restorative materials amalgam (AA), glass ionomer cements (GIC), and Cention N (CN) in Class II restorations using stereomicroscope. Class V cavities were made in thirty intact caries free premolars and restored with restorative materials to be tested respectively. The restored teeth were stored for 24 h in distilled water and thermocycled for 500 cycles between 5°C and 55°C with a dwell time of 30 s in each bath. Samples were immersed in 0.5% basic fuchsin dye for 24 h. The teeth were sectioned along the buccolingual direction. Microleakage was evaluated under a stereomicroscope and data subjected to statistical analysis. The study concluded that out of all the restorative materials, CN a newer restorative material displayed minimum microleakage compared to AA and GICs.
Keywords: Microleakage, glass ionomer cements, restorative materials.
