Microleakage along Glassix glass fibre posts

Aim was to evaluate microleakage along Glassix fibre posts (Harald Nordin sa, Switzerland) cemented with three different materials. The roots of central maxillary incisors were root filled and restored with Glassix posts cemented with Harvard cement (Richter & Hoffmann, Harvard dental GmbH, Germany), Fuji PLUS cement (GC Corporation, Japan) and Variolink cement (Vivadent, Liechtenstein) in three groups og 15 canals each. Twenty un-restored root served as a control group (10 filled with gutta-percha and sealer, the remaining 10 filled with gutta-percha only). Coronal microleakage was evaluated using a fluid transport system. The movement of an air bubble in a capillary glass tube connected to the apex of the experimental root section was measured over 5-min periods. Measuring was performed four times for each specimen and the mean values recorded. Analysis of variance and duncan tests were performed. The highest values of microleakage occurred in the group of canals in which glassix posts were cemented with Harvard cement, followed by PLUS cement and Variolink cement. Fuji PLUS and Variolink had statistically less (P>0.00001) microleakage compared with Harvard cement. Canals with Glassix posts cemented had least leakage.
