“…Debris expulsion from the apical foramen in the course of the biomechanical preparation of the root canal has been associated with post-operative pain [ 2 ]. Such debris may include microorganisms, irrigating solutions, infected dentin particles and pulpal tissue remnants, and their extrusion could depend on different factors; among those, the instrumentation strategies and irrigation play a crucial role [ 3 ].…”

This investigation aimed to examine the post-operative pain experienced following single-visit root canal treatment using the XP-endo shaper sequence (XPS), full-sequence self-adjusting file (SAF), and manual K-files (HKF). A randomized equivalence parallel design, double-blinded clinical study was conducted on 120 patients with symptomatic irreversible pulpitis, with or without clinical signs of apical periodontitis. Only teeth with fully formed roots and no periapical lesions were incorporated in the study. Patients were apportioned to one of three groups (n = 40) randomly: Group 1—XPS, Group 2—SAF, and Group 3—HKF. Pre- and post-instrumentation pain was rated utilizing Visual Analog Scale (VAS) with a spectrum of 0–100 mm. The descriptive statistics and one-way ANOVA with 95% confidence intervals were used for statistical analysis. The mean VAS scores before instrumentation were consistent in all three groups. At 6, 24, 48, and 72 h, patients with root canals instrumented by SAF had the lowest post-instrumentation mean VAS score, followed by XPS. For all time intervals, the patients in the HKF group had the highest VAS score. The full-sequence SAF instrumentation resulted in less post-operative pain than the XP-endo plus protocol, while manual instrumentation with K-files resulted in the highest post-operative pain.

“…Despite this, over the years, several limitations have been highlighted. Firstly, reciprocating instruments have been criticized for the possibility of extruding debris and bacteria in the periapical space in comparison to continuous rotary instrumentation [3,7,8]. Despite this, to date, the literature includes conflicting results, so further studies are needed [3].…”

The aim of this study is to assess the surface alterations of four reciprocating instruments before and after the shaping of four resin-simulated root canals. The following four different reciprocating instruments are selected: 10 Reciproc Blue (RB25), 10 WaveOne Gold (WOG), 10 EdgeOne Fire (EOF) and 10 recently introduced instruments OneRECI (OR), for a total of 40 new instruments. Before root canal shaping, each instrument is mounted on a stub in a standardized position and observed using a scanning electron microscope (SEM) to detect any surface alteration, such as microfractures, metal defects, deformations, blunt and disruption of cutting edges, debris, pitting and tip flattening. Micrographs are acquired at the level of the tip, 4 mm, 8 mm and 12 mm from it. After that, each instrument is used in four simulated resin root canals. SEM observation was repeated after the simulated clinical use to assess the wear resistance of the instruments. Surface alterations are registered before and after instrumentation and statistical analysis is performed using a Chi-Square test to verify homogeneity of defects distribution and GLM to evaluate the differences of RMS at baseline and after use for both groups (α level 0.05). Before simulated clinical uses, no alterations are found except for three cases of EOF with metal strips in correspondence to the tip, disruption of the cutting edge of WOG and oily spotting on two different OR. After simulated clinical use, EOF shows a statistically significant difference in terms of spiral distortion and flattening of the cutting edges. The OR shows the highest presence of debris despite the ultrasonic cleaning procedures. No instrument fractures are observed. EOF should be discarded after four clinical uses and carefully inspected after each insertion into root canals. Moreover, tough attention should be paid during disinfection and cleaning procedures after instrumentation considering the copious debris detected in each instrument, particularly in OR.

Aim. To evaluate the advantages of working with the Endoactivator device on the example of a series of clinical cases concerning the treatment of chronic apical periodontitis. Materials and methods. The series of clinical cases included five patients (two men and three women) who were treated for chronic apical periodontitis (diagnosis according to ICD-10 K04.5). The patients underwent endodontic treatment in two visits, namely, mechanical treatment with rotating nickel-titanium instruments, drug treatment using an Endoactivator device for sound activation of irrigation solutions and the introduction of calcium hydroxide between visits. Postoperative sensitivity was assessed according to the criteria: absent, low, medium and high. The patients informed the research doctors via messengers about the intensity of postoperative soreness. Results. Next results of postoperative sensitivity have been revealed: none of the patients noted high postoperative soreness, average soreness was noted by one patient, low soreness was noted by two patients and absence of soreness was noted by two patients. Conclusions: on the example of this series of clinical cases, convenient manipulation characteristics of the EndoActivator device were revealed. There were no cases of high postoperative sensitivity after operation of these devices in the presented series of cases. In all clinical cases, radiological methods confirm the positive dynamics of healing of periapical foci.
