Abstract

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 mechanical instruments 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.
