目的比较两种根管治疗方法的根管充填质量、封闭剂挤出量和根尖病变的愈合率。假设测试是，这两种技术提出了类似的根尖牙周炎愈合的结果。材料与方法本研究是一项平行设计、实用、随机的临床试验。120颗前牙坏死牙髓和根尖周炎随机分配到器械与手锉和充填与横向压实技术或器械与一个单一的文件在往复运动和充填与单锥技术。根管充填质量、根尖周炎发生率、根尖周炎愈合情况是观察的结果。通过卡方分析对数据进行分析，并使用逻辑回归模型（α = 0.05）调整愈合的比值比。结果两种根管治疗方法在根管充填质量和根管挤出方面无显著性差异。治疗6个月后，两种根管治疗技术在根尖周炎愈合方面表现出相同的结果。愈合率仅受基线时根尖周状态的影响。结论前牙根管充填采用往复式根管锉配合单锥根管充填的质量与手动器械加侧方加压技术的质量相似。根尖病变的愈合率也相似。
Objectives To compare the root filling quality, the sealer extrusion, and the healing rates of apical lesions addressed via two endodontic treatment approaches. The hypothesis tested was that both techniques present similar apical periodontitis healing results. Materials and methods This study was a parallel-design, pragmatic, and randomized clinical trial. One hundred twenty anterior teeth with necrotic pulps and apical periodontitis were randomly allocated to be either instrumented with hand files and obturated with the lateral compaction technique or instrumented with a single file in a reciprocating movement and obturated with a single-cone technique. The root canal filling quality, the occurrence of sealer extrusion, and apical periodontitis healing were the outcomes of interest. Data were analyzed through chi-square analysis, and the odds ratio for healing was adjusted using a logistic regression model (alpha = 0.05). Results No significant differences were observed between the endodontic techniques regarding the root filling quality or sealer extrusion. Six months after treatment, both endodontic techniques presented equivalent results regarding apical periodontitis healing. The healing rate was affected only by the periapical status at baseline. Conclusions The obturation of the root canal of the anterior teeth using reciprocating file-matched single cones presented a similar quality to that obtained with manual instrumentation followed by the lateral condensation technique. Similar healing rates of apical lesions were also observed.
