Abstract
Aim:To evaluate the impact of ProTaper Next and Videya N rotary files on root fracture resistance during chemo-mechanical root canal preparation with and without root canal filling.
Methodology:The following files were used to randomly divide a total of 40 newly extracted mandibular premolars into 5 equal groups (n=8); group 1 prepared using ProTaper Next files without filling; group 2 prepared using ProTaper Next files and filled with guttapercha and Totalfil bioceramic sealer; group 3 prepared using Videya N files without filling; group 4 prepared using Videya N files and filled with guttapercha and Totalfil bioceramic sealer; and group 5 without preparation or filling as a control. Using a universal testing machine, all roots were loaded until they fractured, at which point the weight required in Newtons was recorded. The one-way ANOVA test and post hoc analysis were used to quantitatively analyse the data.
Results:The 4 experimental groups without a statistically significant difference between them considerably decreased the fracture resistance of the roots in comparison to the control group.The filled groups showed a non-statistically significant increased fracture resistance compared to the non-filled ones.
Conclusion:Chemo-mechanical root canal preparation decreases the roots’ fracture resistance. Root canal filling using bioceramic sealers might enhance the roots’ fracture resistance.
