“…Another limitation of the present study is that sample calculation was performed for the main outcome (reduction in periapical index) of a large trial (Figueiredo et al 2020), but not for OHRQoL. A prior similar study comparing changes on OHIP scores after the root canal treatment using either rotary or reciprocating files performed a sample size calculation for this outcome, and only 61 participants were included in that trial (Oliveira et al 2019). Therefore, the number of participants included in the present trial was almost two-fold that from the former trial.…”

Aim To assess the impact of two root canal treatment protocols on the oral health‐related quality of life (OHRQoL) of patients in need of root canal treatment on their anterior teeth. Methodology The sample consisted of 120 participants (mean age: 34 years) enrolled in a pragmatic randomized clinical trial evaluating two root canal treatment protocols. Anterior teeth with nonvital pulps were allocated for root canal preparation with either hand files and filled with lateral compaction of gutta‐percha (manual protocol) or canal preparation with a single file in a reciprocating movement and filled with a single cone technique (Reciproc protocol). OHRQoL data were assessed using the Oral Health Impact Profile instrument (OHIP‐14), which was administered before the root canal intervention (baseline), and 6 and 12 months after treatment. Demographic and clinical characteristics of participants were collected at baseline. Data were analysed using bivariate analyses, Poisson univariate and multiple regression (α = 0.05). Results The drop‐out rate from baseline was 27% and 28% at 6 and 12 months after treatment, respectively. Both root canal protocols significantly enhanced patients' OHRQoL, regardless of the follow‐up time (P < 0.001). After 6 months, patients treated with the Reciproc protocol had significantly lower OHIP‐14 overall scores (P = 0.030), as well as significantly lower scores for psychological discomfort (P = 0.031) and social disability (P = 0.013). After 12 months, no significant difference was observed between the two root canal protocols for OHIP‐14 overall scores (P = 0.174). Either large or moderate effect sizes were observed for all domains and overall scores at both evaluation times, irrespective of the protocol. Low‐income persons (RR = 2.03) and the Reciproc protocol (RR = 1.52) had a higher likelihood of a positive impact on OHRQoL 12 months after root canal treatment. Conclusions The two root canal protocols improved the OHRQoL and differences in scores were observed only after 6 months with poorer OHRQoL for the manual protocol. After 12 months, patients with low‐income status and treated with Reciproc were associated with a greater improvement in OHRQoL scores.

“…1 year). Two previous studies investigated the short-term impact of reciprocating systems on OHRQoL, but these evaluations were limited to assess OHRQoL changes 24 h (Oliveira et al 2019) or 14 days (Bartols et al 2016) after treatment ended. These studies found a positive impact of reciprocating systems on OHRQoL.…”

“…At the same time, it is fundamental to avoid an undesirable extrusion of debris in the periradicular tissues that can be associated with the induction of inflammation and delayed periapical healing [ 19 , 20 ]. Furthermore, apical extrusion is one of the most important factors associated with postoperative pain that seems to be related to the instrumentation technique [ 21 ]; hence, its evaluation is considered relevant from a clinical point of view.…”

The objective of this study is to evaluate the retreatment time and weight of apically extruded debris yielded by two different kinematics during the removal of different root canal filling materials. Forty straight single-rooted extracted teeth were instrumented with HyFlex CM files and obturated with two different techniques: 25.04 HyFlex experimental carrier-based obturators (Coltène/Whaledent, Altstätten, Switzerland) (group 1) or 25.04 single gutta-percha cones (Roeko Coltène/Whaledent, Altstätten, Switzerland) (group 2) and Guttaflow Bioseal as the sealer. Samples were divided into four subgroups (n = 10) according to the used kinematics for the removal of root canal filling materials: continuous rotation (A) or retreatment motion (B) with a Remover and HyFlex EDM Nickel-Titanium instruments activated with a CanalPro Jeni micromotor (Coltène/Whaledent, Altstätten, Switzerland). Time for retreatment was digitally recorded, and debris extruded from the apex was collected in Eppendorf tubes and weighted with an analytical balance. Data on retreatment time and apical extrusion were statistically analyzed with the Kruskal–Wallis test ( p < 0.05 ). Working length was achieved in all the retreated samples. The removal of root filling material resulted significantly faster with the Jeni mode ( p < 0.001 ), and the difference was significant for the removal of both filling materials ( p < 0.05 ). No significant differences on debris extrusion between single cone and experimental obturators groups were noted ( p > 0.05 ), and no significant differences between kinematics (continuous rotation vs. Jeni motion) were observed ( p > 0.05 ). All the tested retreatment strategies lead to an extrusion of material from the apex, and the weight of apically extruded debris was similar. The use of the innovative CanalPro Jeni kinematics accelerates the time for the removal of root filling materials.

“…The latter aspect, apical debris extrusion, is claimed to exert a clinically relevant impact on post-endodontic pain and thus on quality of life of patients after nonsurgical root canal treatment [5][6][7][8]. During the procedure of root canal preparation, pulp tissue remnants, dentine chips, microorganisms, and solutions used for canal irrigation may be extruded apically into the periradicular tissues [4,9].…”

The aim was to evaluate the canal straightening and the amount of apically extruded debris associated with five rotary nickel-titanium when preparing curved root canals. A total of 100 root canals in extracted human teeth (angles of curvatures 20°–30°; radii 5.9–13.5 mm) were divided into five groups (n = 20/group). The groups were balanced with respect to the angle and the radius of canal curvature. The root canals were prepared using conventional austenite 55-NiTi alloy instruments F360, F6 SkyTaper (both Komet, Lemgo, Germany), and the heat-treated NiTi Jizai, Silk-Complex and Silk-Standard instruments (all Mani, Tochigi, Japan) to an apical size 25. The amount of extruded debris was assessed with a micro balance. Statistical analysis was performed using Kruskal–Wallis test with Bonferroni correction at a significance level of p < 0.05. During canal preparation, neither instrument fractures nor procedural preparation errors were noticed. Regarding canal straightening, the use of Jizai instruments resulted in the significantly lowest straightening (p < 0.05), while no significant differences were obtained between all other groups (p > 0.05). Regarding the amount of apically extruded debris, no significant differences between all groups were obtained (p > 0.05). Within the limitations of this study, all instruments performed well, and especially the Jizai instruments showed an excellent shaping ability.
