Zusammenfassung: | The remaining filling material after retreatment can harbor bacteria and organic tissues that can influence the outcome of the therapy.
The aim of this study was to evalúate, by micro-CT, the amount of filling material remaining in the root canal after its removal using WaveOne Gold or ProDesign RT.
Forty human mandibular canines were instrumented with the ProTaper Next system up to the X2 instrument (25.06) and filled with gutta-percha cones and AHPlus. Teeth were divided into 2 groups (n=20): WaveOne Gold 25.07 (WOG) and ProDesign RT 25.08 (PRT) for filling removal, after which they were scanned in a micro-CT device to quantify the volume of remaining filling material. The data were subjected to log
transformation, Student 's t-test was performed to account for multiple observationsper sample, significance was set at 5%.
Student 's t-test showed that there was no difference between the two systems regarding the volume of remaining filling material in the thirds: apical (p = 0.392), middle (p = 0.065), or cervical (p = 0.918).
Remaining filling material was present in all groups and both systems were similar in removing root filling material in mandibular canines. |
