Efficacy of WaveOne Gold and ProDesign RT systems in removing filling material: a micro-CT analysis.
The remaining filling material after retreatment can harbor bacteria and organic tissues that can influence the outcome of the therapy.
Aim: 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.
Material and method: 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 10 transformation, Student 's t-test was performed to account for multiple observationsper sample, significance was set at 5%.
Results: 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).
Conclusión: Remaining filling material was present in all groups and both systems were similar in removing root filling material in mandibular canines.
