■基于硅酸三钙的水泥对牙齿健康和生物相容性表现出几种有益的特性,可以诱导生物矿化。
■使用热和冷封堵技术评估基于硅酸三钙的密封剂的密封能力和管内渗透。
■在PubMed进行了电子搜索,Scopus,和WebofScience数据库,用于使用生物陶瓷进行牙髓治疗的牙齿及其在根管闭塞中的密封能力,直到2023年2月为止。
■在90篇文章中,16符合纳入标准,只有10个用于荟萃分析,其中四个涉及肾小管内渗透,四个寻址密封能力,两个解决了这两个变量。在密封能力组中,荟萃分析得出的标准化平均差(SMD)为-1.31,有利于测试组(温暖),具有一定的不显着趋势(p=0.081);关于肾小管内渗透,荟萃分析得出结论,SMD=2.34,有利于试验组(温暖),穿透率显著提高(p=0.032).
■热闭塞技术比冷技术引入了更大的肾小管内渗透,与冷技术相比,密封能力非常出色,接近统计意义。
UNASSIGNED: Tricalcium silicate-based cements exhibit several beneficial properties for dental health and biocompatibility, which can induce biomineralisation.
UNASSIGNED: To assess the sealing ability and intratubular penetration of tricalcium silicate-based sealers using warm and cold obturation techniques.
UNASSIGNED: An electronic search was conducted in PubMed, Scopus, and Web of Science databases for endodontically treated teeth with bioceramics and their sealing capacity in root canal obturation published up to February 2023.
UNASSIGNED: Of the 90 articles, 16 met the inclusion criteria, and only 10 were used for the meta-analysis, of which four addressed intratubular penetration, four addressed sealing capacity, and two addressed both variables. In the sealing capacity group, the meta-analysis concluded a standardised mean difference (SMD) of -1.31 in favour of the test group (warm) with a certain nonsignificant trend (p = 0.081); regarding intratubular penetration, the meta-analysis concluded an SMD = 2.34 in favour of the test group (warm) with significantly greater penetration (p = 0.032).
UNASSIGNED: The warm obturation technique introduced significantly greater intratubular penetration than the cold technique, along with a remarkably superior sealing capacity compared to the cold technique, approaching statistical significance.
