Abstract
Objectives: The aim of this study was to evaluate the bond strength of a new endodontic filling material containing added bioactive glass in comparison to a conventional polydimethylsiloxane-based material. Materials and methods: Fourteen single-rooted teeth were chemomechanically prepared, divided into two test groups and filled with the test material. The samples were embedded in acrylic resin and sectioned into 1 mm thick slices using a diamond saw. An average of 8 samples was obtained from each tooth GuttaFlow2 n=37, GuttaFlow bioseal n= 34). The force required to fracture each individual sample was measured using the ‘push out’ test method. The Kolmogorov-Smirnov test assessed the ‘bonding strength’ distribution, and the Mann-Whitney U test compared bonding strength differences between the filling material groups. Results: The Mann-Whitney U test showed no statistically significant difference between the two tested groups (P > 0.05). Conclusion: No statistically significant differences in bond strength between tested materials were observed.
