Abstract
The aim of the study is to evaluate the effects of resin-based and bioceramic-based sealants on the fracture resistance and push-out bond strength of teeth that have had endodontic treatment.
In this investigation, 80 single-rooted mandibular premolars from humans were employed. After decoronation, the root’s length was measured. The rotating file structure of the Plex V system was used to finish the instrumentation.
The samples were divided evenly between the two experimental sealers used to obturate them, Gutta-flow bioseal and AH Plus. According to the assessment method, each group was then split into two more manageable groups.
The roots were positioned on the universal testing equipment with their long axes vertically aligned in self-curing acrylic blocks to determine fracture resistance. The long axis of the roots was crushed at an acute angle. Each root’s minimum fracture force was computed. Through data collecting and statistical analysis, the push out connection’s strength is determined. In self-curing acrylic blocks, the roots were separated horizontally and arranged vertically along their long axes. Each root’s component was placed within the testing apparatus. Data collection and statistical analysis were performed on the values of each specimen at the time of displacement, which were recorded in Newtons.
According to the findings, the Gutta-flow bioseal-obturated group exhibited lower fracture resistance than the AH + sealer-obturated group. The findings of the push-out test showed a statistically significant difference (p0.001) between the push-out bond strengths of AH + sealer-obturated groups and those of Gutta-flow bioseal-obturated groups between (group I) and (group II).
Between (group I) and (group II), there was a statistically significant difference, where (p0.001). The apical third of the brain had the greatest mean Push-out strengths value, while the coronal had the lowest.
Conclusions:
Given the limitations of the current experiment, it is possible to make the following conclusions: • Roots sealed with GuttaFlow Bioseal showed reduced fracture resistance; and • The apical third of the root had the greatest push out bond strength of both sealers.
