AIM

To analyse the efficacy of non-surgical therapy (NST) in terms of pocket closure (PC) and changes in percentage and number of pockets.

MATERIALS AND METHODS

Three databases (PubMed, EMBASE, and Scopus) were searched up to January 2020. Prospective studies with a minimum follow-up of 12 months and presenting data in terms of PC or number or percentage of pocket depths (PDs) before and after NST on systemically healthy patients were included. Random-effect meta-analyses were performed.

RESULTS

After screening 4610 titles and abstracts, 27 studies were included. Of these, 63.9% of PC was reported by one study. The percentage of PDs ≤3 mm changed from 39.06% to 64.11% with a weighted mean difference (WMD) of 26.14% (p < .001). This accounted for a relative increase of healthy sites of 64.13%. The mean percentage of PD ≥5 mm was 28.23% and 11.71% before and after treatment, respectively, with a WMD of 15.50% (p < .001). The WMD in the number of PDs ≥5 mm before and after treatment was 24.42 (p = .036). The mean number of residual PPD ≥5 after NST was 14.13.

CONCLUSIONS

NST is able to eradicate the majority of the pockets. However, residual pockets after NST may remain and should be considered cautiously for further treatment planning.

目的

分析非手术治疗（NST）在袋闭合（PC）和百分比及口袋数量变化方面的疗效。

材料和方法

检索了三个数据库（PubMed、EMBASE 和 Scopus），截至 2020 年 1 月。纳入了至少随访 12 个月且在系统性健康患者中以 NST 前后 PC 或袋深度（PD）数量或百分比数据呈现的前瞻性研究。进行了随机效应荟萃分析。

结果

在筛选了 4610 篇标题和摘要后，纳入了 27 项研究。其中，1 项研究报告了 63.9%的 PC。PDs ≤3 mm 的百分比从 39.06%变为 64.11%，加权均数差值（WMD）为 26.14%（p < .001）。这意味着健康部位的相对增加了 64.13%。PDs ≥5 mm 的平均百分比分别为治疗前的 28.23%和治疗后的 11.71%，WMD 为 15.50%（p < .001）。治疗前后 PDs ≥5 mm 的 WMD 为 24.42（p=0.036）。NST 后残留的 PPDs ≥5 的平均数量为 14.13。
