The effect of gingival retraction paste versus gingival retraction cord on periodontal tissue health is controversial. The aim of the present study was to evaluate the effect of gingival retraction paste versus gingival retraction cord on periodontal health by a systematic review and meta-analysis and to provide scientific guidelines for gingival retraction method selection in clinical work.
The databases were systematically queried to collect studies exploring the effect of gingival retraction methods on periodontal tissue health in randomized controlled trials. Literature covering the period of January 1998 to April 2017 was extracted and the quality was assessed, followed by a random-effects meta-analysis with standardized mean differences and 95% confidence intervals. Eight studies met the inclusion criteria. The result of meta-analysis revealed that gingival retraction paste exhibited a less deleterious effect on the periodontal tissue compared with the gingival retraction cord technique measured by probing depth, Gingival Bleeding Index, and bleeding on probing (P < .05). However, no statistically significant differences were found in the measurements of Plaque Index, Gingival Index, and gingival recession between these two methods (P > .05).
Gingival retraction paste can work better than the gingival retraction cord method in protecting periodontal tissue health.
牙龈退缩膏与牙龈退缩线对牙周组织健康的影响存在争议。本研究的目的是通过系统评价和荟萃分析评估牙龈退缩膏与牙龈退缩线对牙周健康的影响，并为临床工作中牙龈退缩方法的选择提供科学指导。
系统检索数据库，收集随机对照试验中探讨牙龈退缩方法对牙周组织健康影响的研究。提取1998年1月至2017年4月期间的文献并评估质量，随后进行随机效应荟萃分析，计算标准化均数差和95%置信区间。八项研究符合纳入标准。荟萃分析结果显示，与牙龈退缩线技术相比，牙龈退缩膏在探诊深度、牙龈出血指数和探诊出血方面对牙周组织的有害影响较小（P < 0.05）。然而，在菌斑指数、牙龈指数和牙龈退缩的测量方面，这两种方法之间未发现统计学显著差异（P > 0.05）。
在保护牙周组织健康方面，牙龈退缩膏比牙龈退缩线方法效果更好。
