Abstract

Background: Immediate Dentin Sealing (IDS) is a technique that applies an adhesive layer immediately after tooth preparation, prior to the placement of indirect restorations. This method is gaining attention due to its potential to improve the bond strength and mechanical properties of restorations, particularly in the posterior region where restorations endure significant masticatory forces. The objective of this systematic review and meta-analysis is to evaluate the effect of IDS on the fracture strength of indirect posterior restorations.

Methods: Following PRISMA guidelines, a comprehensive literature search was conducted in four databases: Web of Science, Scopus, Cochrane Library, and PubMed. Inclusion criteria focused on in vitro studies involving human teeth with indirect posterior restorations, published between 2014 and 2023. Studies using IDS were compared to those using conventional methods. The risk of bias was assessed using the Cochrane Collaboration's tool, and a meta-analysis was performed with a random-effects model. The standard mean difference and 95% confidence intervals were calculated to compare fracture strength, with I ² statistics assessing heterogeneity. Forest and funnel plots were employed to visualize results and publication bias, respectively.

Discussion: The results indicate that IDS generally enhances the fracture strength of indirect posterior restorations, particularly with ceramic materials like lithium disilicate. However, the effectiveness of IDS varies depending on the material and restoration type. While some studies demonstrated improved fracture resistance with IDS, others showed minimal benefit, especially with composite restorations. Additionally, IDS improved marginal adaptation and internal fit but increased the risk of severe failures, such as root fractures.

直接牙本质封闭对间接后牙体骨折强度的影响：系统回顾和荟萃分析方案。

背景：即刻牙本质密封（IDS）是一种在牙齿预备后，在放置间接修复体之前立即应用粘接剂层的技术。该方法因其提高修复体的粘结强度和机械性能的潜力而受到关注，特别是在修复体承受显著咀嚼力的后区。本系统综述和荟萃分析的目的是评估IDS对间接后路修复体骨折强度的影响。方法：按照PRISMA指南，在Web of Science、Scopus、Cochrane Library和PubMed四个数据库中进行全面的文献检索。纳入标准集中于2014年至2023年间发表的涉及间接后牙修复的体外研究。将使用IDS的研究与使用常规方法的研究进行比较。使用Cochrane协作工具评估偏倚风险，并使用随机效应模型进行荟萃分析。计算标准均差和95%置信区间来比较断裂强度，使用i2统计来评估异质性。森林图和漏斗图分别用于可视化结果和发表偏倚。讨论：结果表明，IDS通常可以提高间接后路修复体的断裂强度，特别是使用二硅酸锂等陶瓷材料。然而，IDS的有效性因材料和修复类型而异。虽然一些研究表明IDS可以改善抗骨折性，但其他研究显示益处很小，特别是复合修复体。此外，IDS改善了边缘适应和内部配合，但增加了严重失败的风险，如根骨折。系统评价注册：PROSPERO: CRD42024584545（注册日期：08/09/2024）。

期刊介绍： F1000Research publishes articles and other research outputs reporting basic scientific, scholarly, translational and clinical research across the physical and life sciences, engineering, medicine, social sciences and humanities. F1000Research is a scholarly publication platform set up for the scientific, scholarly and medical research community; each article has at least one author who is a qualified researcher, scholar or clinician actively working in their speciality and who has made a key contribution to the article. Articles must be original (not duplications). All research is suitable irrespective of the perceived level of interest or novelty; we welcome confirmatory and negative results, as well as null studies. F1000Research publishes different type of research, including clinical trials, systematic reviews, software tools, method articles, and many others. Reviews and Opinion articles providing a balanced and comprehensive overview of the latest discoveries in a particular field, or presenting a personal perspective on recent developments, are also welcome.
