An in vitro assessment of push-out bond strength for four types of root canal sealers

A fluid-resistant seal must be created for a root canal (RC) treatment to be successful and this is typically accomplished by combining gutta-percha with an RC sealer. The push-out bond strength test is used to evaluate the root canal sealer's effectiveness. Therefore, it is of interest to estimate the push out bond strength of dissimilar root canal sealers.40 human premolar teeth were chosen, and after root canal preparation, 10 samples of each of the following sealant materials were used during obturation using gutta-percha cones: Group I: BIO-C ION + sealer; Group II: AH Plus; Group III: Bioceramic sealer (Sure Seal Root); and Group IV: -MTA-Fillapex. After that, the samples were sectioned into coronal, middle and apical parts by transverse sectioning. A universal testing machine was used to evaluate the push out bond strength (UTM). ANOVA was used to do statistical analysis on the collected data. Compared to the three other sealers, BIO-C ION PLUS sealer's push out bond strength (POBS) was noticeably stronger. The results of this investigation might help clinicians to choose an appropriate endodontic sealer.
