超声器械与手用器械龈下刮治疗效比较的meta分析

Ultrasonic Scaler Versus Hand Instruments for Subgingival Scaling:A Meta-Analysis

目的:通过Meta分析评价超声器械与手用器械龈下刮治比较治疗成人慢性牙周炎的临床疗效。方法:计算机检索PubMed、Cochrane Library、EMbase、CNKI、CBM、WanFang Data等6个电子数据库,查找所有有关超声与手工龈下刮治比较治疗慢性牙周炎的随机对照试验(RCTs)。并追索所有纳入文献的参考文献,文献检索时限均从建库至2012年11月。由2名评价员按照纳入和排除标准独立进行文献筛选、资料提取和质量评价后,采用RevMan 5.0软件进行Meta分析。结果:最终7个RCT、224例受试者纳入本系统评价。Meta分析结果显示,超声与手工龈下刮治术后3个月复查时探诊深度、附着水平的改变无统计学差异;术后6个月复查时探诊深度、附着水平的改变无统计学差异。结论:现有研究证据表明,在牙周基础治疗过程中,采用超声与手工两种方法进行龈下刮治疗效相似。

Objective： To evaluate the clinical effectiveness of ultrasonic scaler versus hand instruments for subgin gival scaling treating chronic periodontitis in adults via meta--analysis. Methods： The following six electronic databases as PubMed,The Cochrane Library, EMbase,CNKI,CBM and WanFang Data were searched on computer from inception to November,2012,and the references of all selected literatures were also retrieved to collect the relevant randomized controlled trials （RCTs） on ultrasonic scaler vs. hand instruments for subgingival scaling treating chro nic peiodontitis. According to the inclusion and exclusion criteria,two reviewers independently screened literatures, extracted data,and assessed the methodological quality of the included RCTs. Then meta--analyses were performed using RevMan 5.0 software. Results： Finally,7 RCTs involving 224 patients that met inclusion criteria were entered into this review. The results of meta--analyses showed that： There were no significant differences in probing depth, clinical attachment level at 3-- month between the ultrasonic group and the hand group. There were no significant differences in probing depth, clinical attachment level at 6- month between the ultrasonic group and the hand group. Conclusion： The current evidence shows that ultrasonic scaler is similar to hand instruments in effectively improving the symptoms of chronic periodontitis in adults.
