Background The most popular approach to treating pulpal and periapical disease is endodontic therapy, but the most common failure after root canal therapy, if not followed by planned rehabilitation of the tooth, is tooth fracture, which may be so severe in some cases needing extraction. Inadequate endodontic restorations increase the risk of fracture and coronal leakage, which can disseminate bacteria and their byproducts and perhaps lead to the failure of root canal therapy. In order to offer protection against masticatory forces along with compressive obturation forces that can lead to vertical root fracture, research has also supported the use of post-endodontic treatment restorative materials with an elastic modulus that is either greater or comparable to the tooth itself for post-endodontic restorations. Restorative materials that can bond to root dentin can be used to create intraorifice barriers, which prevent coronal microleakage and reinforce the radicular dentin. The current in vitro study aims to assess the effects of various intraorifice barriers (an alkasite restorative material versus resin-modified glass ionomer cement) on the sealing ability of the intraorifice barriers following root canal therapy. Methodology In vitro, confocal laser microscopy is used to determine the microleakage of various intraorifice barriers. Conclusion The sealing ability of a post-endodontic restoration is crucial for the overall success of endodontic treatment, and this in vitro study protocol would ultimately help in selecting the appropriate intraorifice barrier.
背景 治疗牙髓和根尖周疾病最常用的方法是根管治疗,但根管治疗后最常见的失败情况(如果不进行后续的牙齿修复计划)是牙齿折断,在某些情况下折断可能非常严重,需要拔牙。根管修复不充分会增加牙齿折断和冠部微渗漏的风险,而冠部微渗漏会使细菌及其代谢产物扩散,可能导致根管治疗失败。为了抵御咀嚼力以及可能导致垂直根折的压缩性充填力,研究也支持使用弹性模量大于或与牙齿本身相当的根管治疗后修复材料进行根管治疗后的修复。能够与牙根牙本质粘结的修复材料可用于创建髓室口屏障,防止冠部微渗漏并增强根管牙本质。当前的体外研究旨在评估各种髓室口屏障(一种碱土硅酸盐修复材料与树脂改性玻璃离子水门汀)对根管治疗后髓室口屏障封闭能力的影响。方法 在体外,使用共聚焦激光显微镜测定各种髓室口屏障的微渗漏情况。结论 根管治疗后修复体的封闭能力对根管治疗的整体成功至关重要,并且该体外研究方案最终将有助于选择合适的髓室口屏障。
