阻生牙拔除术后并发症防治的系统评价/Meta分析的汇总评价

Prevention and Treatment of Complications after Impacted Tooth Extraction: An Overview of Systematic Reviews and Meta-Analyses

目的对防治阻生牙拔除术后并发症的系统评价/Meta分析进行汇总评价。方法计算机检索PubMed、e Cochrane Library、CBM、CNKI和WanFang Data,收集防治阻生牙拔除术后并发症的所有系统评价/Meta分析,同时手工检索15种专业期刊并追溯纳入研究的参考文献,检索时限均为从建库至2012年9月30日。由两位研究者按照纳入标准独立筛选文献、提取资料后,采用AMSTAR评价纳入研究质量并采用GRADE系统进行证据质量分级。结果共纳入12个相关系统评价/Meta分析,其中5个涉及干槽症防治,6个涉及肿胀预防,7个涉及疼痛防治,6个涉及张口受限,2个涉及感染预防,3个涉及出血预防,1个为拔牙术后神经损伤的治疗。基于AMSTAR的质量评价结果显示,7个研究质量为轻度限制,5个为中度限制。GRADE系统的质量评价结果显示,2个研究的证据分级为高级,12个为中级,9个为低级,7个为极低级。结论当前防治阻生牙拔除术后并发症的系统评价/Meta分析结果可为临床实践提供一定参考,临床医生应结合实际情况进行循证决策。此外,仍建议开展更多大样本、高质量研究予以证实。

Objective To evaluate the relevant systematic reviews/meta-analyses that focused on the prevention and treatment of complications after impacted tooth extraction. Methods The systematic reviews/meta-analyses on the prevention and treatment of complications after impacted tooth extraction were searched in PubMed, The Cochrane Library, CBM, CNKI and WanFang Data from inception to September 30th, 2012, and a total of 15 professional journals and the references of included studies were also retrieved manually. Two reviewers screened the literature according to the inclusion criteria and extracted the data. Then the AMSTAR was used to evaluate the quality of the included studies, and the GRADE system was used to evaluate the quality of evidence. Results A total of twelve relevant systematic reviews/ meta-analyses were included, of which five focused on the prevention and treatment of dry socket, six on the prevention of swelling, seven on the prevention and treatment of pain, six on the prevention of limitation of mouth opening, two on the prevention of infection, three on the prevention of bleeding, and one on the treatment of nerve damage after tooth extraction. Based on AMSTAR, seven studies were minor limitations and five studies were moderate limitations. Based on GRADE system, two was high quality of evidence, twelve were moderate, nine were low, and seven were very low. Conclu- sion Currently, the systematic reviews/meta-analyses on the prevention and treatment of complications after impacted tooth extraction can provide some references for clinical practice, which should be combined with the real condition by clinical doctors when making an evidence-based decision. However, it also suggests performing more high quality and large sample studies to prove this conclusion.
