As a dangerous factor in vertical root fracture, dentinal crack formation is often associated with root canal instruments. We conducted this meta-analysis to compare the influence of two types of nickel titanium (NiTi) instruments that have different movements (reciprocating single-file versus full-sequence rotary file systems) on dentinal cracks formation during root canal preparation. Searches were conducted in PubMed, ISI Web of Knowledge, Embase and Cochrane Library using a combination of keywords. Titles and abstracts of all articles were independently assessed by two reviewers in accordance with the predefined inclusion criteria. Relevant studies were acquired in full-text form. Data in these articles were independently extracted. A meta-analysis was conducted using Review Manager 5.3. The results showed that the WaveOne and Reciproc files with a reciprocating motion produced significantly fewer dentinal cracks than the conventional rotational ProTaper technique.
作为垂直根折的一个危险因素，牙本质裂纹的形成常与根管器械相关。我们进行了这项荟萃分析，以比较两种具有不同运动方式（往复式单根锉与全序列旋转锉系统）的镍钛（NiTi）器械在根管预备过程中对牙本质裂纹形成的影响。使用关键词组合在PubMed、ISI Web of Knowledge、Embase和Cochrane图书馆进行检索。两名审稿人根据预先确定的纳入标准独立评估所有文章的标题和摘要。获取相关研究的全文。对这些文章中的数据进行独立提取。使用Review Manager 5.3进行荟萃分析。结果表明，与传统的旋转ProTaper技术相比，具有往复运动的WaveOne和Reciproc锉产生的牙本质裂纹明显更少。
