Assessment of Real-Time Operative Torque during Nickel–Titanium Instrumentation with Different Lubricants

Assessment of Real-Time Operative Torque during Nickel–Titanium Instrumentation with Different Lubricants

The aim of the present study is twofold: to assess ex vivo the role of different lubricants on real-time torque generated during intracanal instrumentation and to check whether two different kinds of torque parameters, operative torque (OT) and average peak torque (APT), could produce similar result...

Forty extracted single-rooted teeth were selected for the present study and divided into four equal groups (n = 10): Group A, NaCl 0.2%; Group B, NaOCl 5%; Group C, ethylenediaminetetraacetate (EDTA), and Group D, EDTA and hydrogen peroxide.

In each sample, mean OT and mean APT were recorded and statistically analyzed with one-way ANOVA and a post hoc Bonferroni between groups (<i>p</i> < 0.05). EDTA (12.11 ± 4.45 Ncm) showed statistically significant <i>(p</i> < 0.05) lower values compared with the other tested irrigant for both parameters. Overall, the two different parameters were both able to differentiate between the influence of lubricants on torsional loads.https://www.mdpi.com/2076-3417/10/18/6201endodonticsnickel–titaniumtorqueroot-canal irrigants
