The objective of the study was to assess the impact of periodontal crown lengthening surgery on clinical parameters at adjacent and non-adjacent sites compared to treated sites.
An electronic search was carried out on MEDLINE-PubMed, The Cochrane Library, and ISI Web of Science databases between 1978 and 2015. Methodological quality assessment was based on Cochrane recommendations. Meta-analyses were assessed with RevMan 5.0 and heterogeneity between studies by the Higgin test (I ). Clinical attachment level (CAL) and probing depth (PD) were the primary outcome variables. Four case series studies were included and three in the meta-analysis. All studies showed high risk of bias.
The surgery promoted significant changes in treated, adjacent, and non-adjacent sites. There were greater changes in PD (mean difference -0.14, 95 % CI -0.18 to -0.10, p < 0.00001) and CAL (mean difference 0.16, 95 % CI 0.13 to 0.20, p < 0.00001) in treated sites when compared to adjacent and non-adjacent sites for PD (mean difference -0.09, 95 % CI -0.12 to -0.05, p < 0.00001) and CAL (mean difference 0.91, 95 % CI 0.87 to 0.94, p < 0.00001).
Crown lengthening surgery results in changes of clinical parameters in treated, adjacent, and non-adjacent sites.
Clinical and esthetic alterations on the adjacent/non-adjacent teeth can lead to clinical and esthetic alterations, which must be considered in surgical planning.
本研究的目的是评估与治疗部位相比，牙周冠延长术对相邻和非相邻部位临床参数的影响。
于1978年至2015年间在MEDLINE-PubMed、考克兰图书馆及ISI科学网数据库进行电子检索。方法学质量评估基于考克兰推荐意见。使用RevMan 5.0进行荟萃分析，并通过希金斯检验（I²）评估研究间的异质性。临床附着水平（CAL）和探诊深度（PD）为主要结局变量。纳入四项病例系列研究，三项纳入荟萃分析。所有研究均显示存在高度偏倚风险。
手术促使治疗部位、相邻部位和非相邻部位发生显著变化。与相邻和非相邻部位相比，治疗部位的PD（平均差值-0.14，95%可信区间-0.18至-0.10，p<0.00001）和CAL（平均差值0.16，95%可信区间0.13至0.20，p<0.00001）变化更大，相邻和非相邻部位的PD（平均差值-0.09，95%可信区间-0.12至-0.05，p<0.00001）和CAL（平均差值0.91，95%可信区间0.87至0.94，p<0.00001）。
冠延长术导致治疗部位、相邻部位和非相邻部位的临床参数发生变化。
相邻/非相邻牙齿的临床和美学改变可导致临床和美学改变，手术规划时必须予以考虑。
