Clinical evaluation of nickel-titanium mechanical instruments in three different movement patterns combined with warm vertical compaction in the single-visit endodontic treatment
Abstract：BACKGROUND:One-visit root treatment has been widely acknowledged by clinicians. The novel nickel-titanium instruments can improve the work efficiency, treatment efficacy and comfort, which not only meet the patients' psychological requirements, but also alleviate the doctors' workload. OBJECTIVE:To evaluate the clinical evaluation of the nickel-titanium mechanicallinstruments in three different movement patterns combined with warm vertical compaction in the single-visit endodontic treatment. METHODS:375 affected teeth from 375 patients with pulp necrosis and periapical periodontitis were randomly allotted to three groups:WaveOne reciprocating, ProTaper rotary and Twisted File Adaptive groups. All the canals of teeth were instrumented with a crown-down technique combined with ultrasonic irrigation, and then subjected to the root canal filling using warm vertical compaction. RESULTS AND CONCLUSION:The root canal preparation time differed significantly among groups (P<0.001), which was the shortest in the WaveOne group, and longest in the ProTaper group. There was no significant difference in the canal obturation among groups (P>0.05). The postoperative pain showed significant difference among groups at 24 and 72 hours (P<0.05). At 7 days postoperatively, there was no significant difference in pain among groups (P>0.05). These results indicate that the WaveOne can significantly improve the canal preparation and shows good molding effect;while the Twisted File Adaptive significantly reduces postoperative pain.
