Cention is an amalgamation of composite resin and glass ionomer cement (GIC) with alkaline fillers, having superior mechanical and aesthetic properties. While the material has proven excellent in providing functional and aesthetic outcomes, its long-term performance in terms of microleakage needs to be studied. The present systematic review was conducted to analyze the currently available evidence concerning the microleakage of Cention and how it fares against GIC in the clinical scenario. A systematic search was performed across various electronic databases, including PubMed, Scopus, Web of Science, and Google Scholar, using the keywords "Cention", "glass ionomer cement", and "microleakage". In-vitro studies assessing microleakage in human extracted teeth after placement of Cention and comparing it to that of GIC were included in the review. Data extraction was performed. The extracted data included study characteristics (authors, publication year, study design), samples used for the study, types of interventions (Cention and conventional GIC), preparatory details (sectioning, thermocycling), and microleakage assessment methods, outcomes, and conclusive findings. The QUIN tool was used for assessing the risk of bias. Based on the conclusive findings presented by the authors of the studies included in the current systematic review, it was apparent that Cention exhibited lower microleakage when compared to GIC. Meta-analysis revealed that the reduction in microleakage on average was 3.12 times more in the Cention group compared to the conventional GIC, and the difference was not statistically significant (p>0.05). The majority of the included studies in the present systematic review found that Cention tended to have lower microleakage compared to conventional GIC, supporting its effectiveness in reducing leakage at the tooth-restoration interface. Our meta-analysis indicates a trend toward reduced microleakage in the Cention group. However, the lack of statistical significance and the presence of substantial heterogeneity and publication bias highlight the need for cautious interpretation.
Cention是一种由复合树脂和含碱性填料的玻璃离子水门汀（GIC）混合而成的材料，具有优异的机械性能和美学性能。虽然该材料在提供功能和美学效果方面已被证明非常出色，但其在微渗漏方面的长期性能仍需研究。本系统评价旨在分析目前关于Cention微渗漏的现有证据，以及它在临床情况下与GIC相比的表现。通过使用关键词“Cention”、“玻璃离子水门汀”和“微渗漏”，在包括PubMed、Scopus、Web of Science和谷歌学术在内的各种电子数据库中进行了系统检索。本评价纳入了评估在人类离体牙中放置Cention后的微渗漏情况并将其与GIC进行比较的体外研究。进行了数据提取。提取的数据包括研究特征（作者、发表年份、研究设计）、研究使用的样本、干预类型（Cention和传统GIC）、准备细节（切片、热循环）以及微渗漏评估方法、结果和结论性发现。使用QUIN工具评估偏倚风险。根据当前系统评价中纳入研究的作者提出的结论性发现，很明显Cention与GIC相比表现出更低的微渗漏。荟萃分析显示，与传统GIC相比，Cention组微渗漏平均减少量多3.12倍，且差异无统计学意义（p>0.05）。本系统评价中纳入的大多数研究发现，与传统GIC相比，Cention往往具有更低的微渗漏，这支持了其在减少牙齿修复界面渗漏方面的有效性。我们的荟萃分析表明Cention组有微渗漏减少的趋势。然而，缺乏统计学意义以及存在大量异质性和发表偏倚凸显了谨慎解读的必要性。
