The purpose of this randomised clinical trial study was to compare the incidence and intensity of post-operative pain following the use of single-file and multi-file rotary instruments with continuous rotational motion for root canal preparation in asymptomatic permanent human teeth.
A total of 105 healthy consenting patients who fulfilled specific inclusion criteria and had premolar or molar teeth diagnosed with asymptomatic irreversible pulpitis without periapical pathosis requiring endodontic treatment participated in this study. The patients were randomly allocated by stratification into five groups of 21 according to the instruments and systems used for root canal preparation: (a) Neoniti A1 (#25) single file, (b) RaCe #25/.06 single file, (c) Mtwo #25/.06 single file, (d) Easy RaCe, (e) and Mtwo multifile. Endodontic treatment was carried out in a single appointment. The severity of post-operative pain was assessed by numerical rating scale scores until complete pain relief was achieved. Analgesic consumption and the incidence of pain were also evaluated. Data were analysed by one-way ANOVA and Tukey HSD tests.
When comparing different instruments and systems for canal preparation, the analgesic consumption, incidence and intensity of post-operative pain did not differ (p>0.05). The highest levels of post-operative pain were experienced after 6 h in all groups.
The post-operative pain did not differ between the single and multi-file root canal preparation techniques evaluated in this study.
本随机临床试验研究的目的是比较在无症状恒牙根管预备中使用单根和多根旋转器械连续旋转运动后术后疼痛的发生率和强度。
共有105名符合特定纳入标准、患有诊断为无症状不可逆性牙髓炎且无根尖周病变需要根管治疗的前磨牙或磨牙的健康受试者参与本研究。根据用于根管预备的器械和系统，将患者按分层随机分为五组，每组21人：（a）Neoniti A1（#25）单根锉，（b）RaCe #25/.06单根锉，（c）Mtwo #25/.06单根锉，（d）Easy RaCe，（e）Mtwo多根锉。根管治疗在一次就诊中完成。通过数字评分量表评分评估术后疼痛的严重程度，直至疼痛完全缓解。还评估了镇痛药的消耗量和疼痛发生率。数据采用单因素方差分析和Tukey HSD检验进行分析。
比较不同的根管预备器械和系统时，术后疼痛的镇痛药消耗量、发生率和强度无差异（p>0.05）。所有组在术后6小时经历的术后疼痛程度最高。
本研究评估的单根和多根根管预备技术之间的术后疼痛无差异。
