Effect of Solvent Use on Postoperative Pain in Root Canal Retreatment: a Randomized, Controlled Clinical Trial
(Springer Heidelberg, 2020) Sen, Ozgur Genc; Erdemir, Ali; Canakci, Burhan Can
Objectives The aim of this randomized clinical trial was to assess the effect of solvent use during the removal of root canal filling on postoperative pain after retreatment. Materials and methods Ninety patients scheduled for root canal retreatment were randomly assigned to one of the following two groups according to the root canal filling removal procedure used: ProTaper retreatment (Dentsply Maillefer, Ballaigues, Switzerland) instruments or ProTaper retreatment instruments in combination with gutta-percha solvent. A single operator performed the retreatments in a single visit. The incidence and intensity of the postoperative pain were rated on a numeric rating scale by patients at 24, 48, and 72 h after retreatment. The analgesic tablet intake number was also recorded. Data were analyzed using Mann-Whitney U, Wilcoxon, and chi-square tests. Results For the intensity of postoperative pain, the difference between the two groups was not statistically significant. Moreover, no statistically significant difference was found between the two groups in terms of analgesic medication intake (P > 0.05). Conclusions The processes involving the use and non-use of a solvent in the removal of root canal fillings were found to be equivalent in terms of postoperative pain intensity and analgesic intake.
The Effect of Two Rotary and Two Reciprocating Niti Systems on Postoperative Pain After Root Canal Retreatment on Single-Rooted Incisor Teeth: a Randomized Controlled Trial

Aim This randomized clinical trial aimed to assess the effect of two rotary (ProTaper Retreatment + ProTaper Gold and Hyflex EDM) and two reciprocating (Reciproc Blue and WaveOne Gold) NiTi systems on postoperative pain after root canal retreatment on single-rooted incisor teeth. Methodology One hundred and eighty patients scheduled for root canal retreatment were randomly assigned to one of the four groups according to the NiTi system (ProTaper Retreatment + ProTaper Gold, Hyflex EDM, Reciproc Blue or WaveOne Gold) used for the removal of root canal fillings and further canal preparation. The working length was determined to be 1 mm shorter than the '0.0' mark of the apex locator. Root canals were filled with gutta-percha and an epoxy resin-based root canal sealer using a lateral compaction technique. The teeth were restored using a resin composite material. A single operator performed the retreatments in a single visit. The incidence and intensity of postoperative pain were rated on a numeric rating scale by patients 24, 48 and 72 h after retreatment. The number of analgesic tablets (400 mg Ibuprofen) taken by patients was also recorded. Data were analysed using the Mann-Whitney U, Wilcoxon and chi-square tests. Results For the intensity of postoperative pain, the difference between the four groups was not significantly different (p > .05). No significant difference was found between the groups in terms of analgesic medication intake (p > .05). Conclusions The rotary and reciprocating NiTi systems tested in this study were associated with similar intensity of postoperative pain and intake of analgesics following root canal retreatment on single-rooted incisor teeth completed in one visit.
Evaluation of Apically Extruded Debris From Curved Root Canal Filling Removal Using 5 Nickel-Titanium Systems

Introduction: This study evaluated the amount of apically extruded debris in the retreatment of curved root canals using different nickel-titanium (NiTi) systems: the ProTaper Universal Retreatment (Dentsply Maillefer, Ballaigues, Switzerland), Mtwo Retreatment (VDW, Munich, Germany), D-Race Retreatment (FKG Dentaire, La Chaux-de-Fonds, Switzerland), R-Endo Re treatment (Micro-Mega, Besancon, France), and Reciproc (VDW) systems. Methods: One hundred human mandibular premolars with curved root canals were prepared with the Reciproc #25. 08 NiTi system filled with AN Plus Jet (Dentsply DeTrey, Konstanz, Germany) sealer and gutta-percha and divided into 5 groups (n = 20). The canal filling was removed with the Pro Taper, Mtwo, D-Race, and R-Endo retreatment systems and Reciproc instruments. Final preparation was done with the Reciproc #40.06 NiTi system. Extruded debris was collected in preweighed Eppendorf tubes. The times required for retreatment were recorded. Results: Reciproc produced significantly (P <.001) more debris than the other systems. ProTaper R and Mtwo R produced significantly (P <.001) more debris than D-Race and R-Endo. The Reciproc group required significantly (P <.001) less preparation time than the other groups. Conclusions: In the retreatment of curved root canals, the Reciproc system extruded significantly more debris than the rotary retreatment NiTi systems. In addition, the ProTaper and Mtwo retreatment systems extruded significantly more debris than the R Endo and D -Race systems. The Reciproc system was significantly faster than the rotary retreatment systems.
