聚乙烯基醚硅氧烷(PVES)具有用于制作精确和准确的牙科印模的理想特性。PVES的尺寸稳定性归因于其母体材料聚醚和聚乙烯基硅氧烷的更好的聚合物性能。随着化学消毒剂的推荐使用越来越受欢迎,人们越来越关注消毒剂对PVES尺寸稳定性的影响。本研究旨在了解PVES在化学消毒剂作用下的行为。
这些数据是从GoogleScholar检索的研究中收集的,Scopus,和PubMed使用关键字“乙烯基聚醚硅氧烷和消毒”或(乙烯基聚醚硅氧烷或聚乙烯硅氧烷醚或PVES)和(消毒剂或消毒)“的MeSH术语,对出版日期没有任何限制。在数据收集期间观察到PRISMA(系统评价和荟萃分析的首选报告项目)方向,筛选研究,和荟萃分析。检索了主要数据,并使用Harzing的Publish或Perish软件从数据库中批量导出;主要分析在MicrosoftExcel中进行,而效应大小的统计分析,双尾p值,研究之间的异质性使用MetaEssentials进行。使用Hedge'sg值在95%置信水平下使用随机效应模型计算效应大小。使用CochraneQ和I2测量研究之间的异质性。
由PVES弹性印模材料制成的牙科印模在尺寸稳定性方面没有显著变化。浸入化学消毒剂10分钟与PVES印象尺寸的临床无关变化有关。用次氯酸钠消毒与尺寸的临床显着变化有关,双尾p值为0.049。用2-2.5%戊二醛溶液消毒与任何显着的尺寸变异性无关。
Polyvinyl ether siloxane (
PVES) possesses ideal characteristics for making precise and accurate dental impressions.
PVES dimensional stability owes to its better polymeric properties derived from its parent materials poly ethers and polyvinyl siloxanes. As recommended use of chemical disinfecting agents is getting more popular, there is a growing concern associated with the effect of disinfectants on
PVES dimensional stability. This study was aimed to understand the
PVES behavior when subjected to chemical disinfectants.
The data was collected from research studies retrieved from Google Scholar, Scopus, and PubMed using MeSH terms of keywords \"vinyl polyether siloxane AND Disinfection\" or (Vinyl polyether siloxane OR polyvinyl siloxane ether OR PVES) AND (disinfectant OR disinfection)\" without any restriction to publication date. The PRISMA (Preferred Reporting Items for Systemic
Review and Meta-Analysis) directions were observed during the data collection, screening of studies, and meta-analysis. The primary data were retrieved, and batch exported from databases using Harzing\'s Publish or Perish software; primary analysis was performed in Microsoft Excel, while statistical analysis for effect size, two-tailed p-values, and heterogeneity among studies was performed using Meta Essentials. The effect size was calculated using Hedge\'s g values at the 95% confidence level using the random-effects model. Heterogeneity among studies was measured using the Cochrane Q and I2.
Dental impressions made from the PVES elastomeric impression materials showed no significant changes in dimensional stability. Immersion in the chemical disinfectant for 10 min was associated with clinically irrelevant changes in the dimensions of the PVES impressions. Disinfection with sodium hypochlorite was associated with clinically significant changes in dimensions, with a two-tailed p-value of 0.049. Disinfection with 2-2.5% glutaraldehyde solution was not associated with any significant dimensional variability.
