“…Forty-eight articles were excluded because they did not meet the inclusion criteria. 46 - 93 One of the main reasons for exclusion was that extrusion was evaluated with different methods instead of weighing debris, such as visual evaluation 51 - 53 , 74 , 81 , 87 , 89 , 90 , 93 or measuring the volume of debris. 49 , 54 , 55 Eleven articles were excluded because data regarding incubation conditions after NSRCRT procedures were missing.…”

Background. This study aimed to systematically and comprehensively review the effect of various treatment variables on apically extruded debris (AED) during non-surgical root canal retreatment (NSRCRT). Methods. The study protocol is shared in the Open Science Framework database (https://osf. io/kjtdg/?view_only=17060180705745ec9dae9a01614f3880). An electronic search was conducted up to July 2022 to reveal related studies. Two reviewers critically assessed the studies for eligibility against inclusion and exclusion criteria and data extraction. Quantitative data synthesis was performed, and the risk of bias in the studies was also evaluated. Results. Forty-six studies were included in the systematic review and 14 in the meta-analysis. Conflicting or limited evidence was found for the effect of sealer type, obturation technique, and solvent use. The manual instrumentation increased the amount of AED compared to rotary instrumentation during the removal of filling materials (P<0.001). There was no significant difference in the amount of AED between the use of rotary and reciprocating files during the removal of filling materials (P=0.181). Conclusion. Rotary instruments can be recommended instead of manual instruments during the removal of filling materials to control the amount of AED. Further studies with a low risk of bias are needed to clarify the effect of other treatment variables on AED during NSRCRT.

Background/Aim. During retreatment, filling material and debris may extrude and trigger an inflammatory reaction of periapical tissues. Resilon? has not been investigated in terms of solvent use and influence on apical extrusion during retreatment. This study evaluated the amount of apically extruded debris during Resilon? removal using ProTaper, Twisted File and Hedstrom instruments, with and without solvent. Methods. In total, 72 extracted teeth with single canal were used. Canals were prepared with ProTaper Universal (F2) and filled with Resilon? and RealSeal sealer, before being assigned randomly to 6 groups (n=12 each). Retreatment in groups 1, 2 and 3 was done with ProTaper, Twisted File or Hedstrom instruments, without solvent; in groups 4, 5 and 6 the same instruments were used with chloroform. Apically extruded debris was collected in a simulated periapical environment and assessed visually. Additionally, the time required for retreatment was recorded. Data were analysed statistically using Mann-Whitney U test, with a significance level of 0.05. Results. There were no significant differences in apical extrusion debris between groups (p > 0.05) regarding solvent use. Rotary instruments, without solvent, were associated with significantly less debris extrusion when compared with hand files (p < 0.05). When solvent was used, rotary instruments caused higher degree of extruded material, that was similar to the results of hand instruments. Conclusion. Within the limitations of this study, the use of rotary instruments without solvent resulted in a lower degree extrusion of Resilon ? material compared to hand instruments, while greater caution is advised in the presence of solvent when rotary instruments are used to remove this material.
